Outdoor heating systems are very popular among homeowners. The best solution for creating heat in a private house may be the installation of water floors. However, to make the right choice and to install it in the room - a difficult task, since this process has its own nuances and requires some knowledge.

Features: Pros and Cons

Water warm floor is a construction of a heating circuit consisting of pipes. They are connected to the main heating system.

The undoubted advantages of such a device are considered:

• The rationality of the use of energy, which avoids significant waste of material resources. When installing such a system, electricity monetary costs decrease almost twice.
• Creating comfort and comfort in the dwelling.
• Uniform distribution of heat all over the room.

• A fairly high level of security due to the fact that the coolant is located under the floor, therefore there is no risk of getting a burn or injury.
• Indelible compatibility with finishing materials. For example, the device is easily suitable for coatings such as tile, linoleum or laminate. If materials with chemical additives are used, then it should be specified on the package. Check whether the manufacturer allows the manufacturer to establish such products in residential premises.
• Connection variability. So, you can connect immediately to the main heating system, and you can create separate design Heat supply.

However, a warm water floor system has some minuses:

• To obtain a small heating temperature, you need to have a mixer that works in a complex with a water pump.
• It often leads to a decrease in pressure in central heating.
• It takes a lot of time on the installation due to the need to create multi-layered installation.
• In the event of the appearance of leaks, you need to open all the coverage that it entails its possible damage.
• Warm water floor will not cope with the heating of the entire premises, so there must be a boiler for heating the entire space.

In general, such a design has more advantages and, of course, will be the Savior in the winter season. It is not recommended to disable the winter system.

Mounting schemes

The quality of the material is distinguished by the following types of laying of warm water floor in a country cottage, in the country:

• Concrete. Here is a screed with mounted waterproofing and thermal insulation, fixing pipes with a reinforcing grid. As a fastening, a tile, stone or parquet board are used as a cover.
• Polystyrene.. This is a simple installation option using special polystyrene slabs, which after pressing is obtained by a convex form. Pipes are placed inside.
• Wooden overlaps.

For the last mounting scheme is quite simple. For a device of such a method of heating in private wooden houses, there are several methods for laying water structures on a dumping surface. Under the floor, plastic tubes are installed. They provide the receipt of hot water.

The maximum heating temperature of such surfaces is no more than 30 degrees, otherwise the drying of the wooden coating will begin.

Circulation hot water occurs constantly. It is important to remember that the heating system indoors is not related to the heating of the floor. The process of heating is carried out by boilers of any kind. Most. the best option It will be if the boiler consists of two heating circuits. That is, one of them is designed to create heat in the indoors itself, and the other is for a warm-alone system.

This design will save money, as the air begins to rise from the bottom up, and the convectors create heat during the receipt of cold from the windows. The water heating floor system, which is based on the gas boiler, is the following:

• Pipe entering natural gas.
• Pipe for water supply.
• Heating system feed line in two directions.
• Collector.
• Two directions for water warm floor.

Technology arrangement

Installation of the heating system is possible only after necessary training Basis. This is done to create an ideal overlap by restoring or replacing it. This stage includes important points:

• Removing the old coating and dismantling a rough base.
• Removing all types of isolation.
• Purification of the surface from contamination.
• Verification of structures for stability by inspection. If worn parts of the beams are detected, they need to be cut and replaced with a piece of the same size.
• Use of substances to protect against fungus and mold.

It is important to pay attention to the fatality of the foundation, the presence of protrusions. You can not allow too much large drops. If the surface defects are greater than 2 cm, then it is necessary to make alignment by imprints of small rubble. This method is suitable for laying warm water under wooden floors.

Installation of light water floor can be made both with a screed, and by means of dry floor under the tile or tree. It is important to know that start mounting the floors better in the room where the boiler is located. One section for mounting should not have an area of \u200b\u200bmore than 40 m.Truba for installation have the ability to deformation, so it is not difficult to give heating elements Any shape. Experts believe that the method of laying a spiral is most effective.

Can be used both plastic and metal plastic pipes. Often specialists use polypropylene devices that are distinguished by stability, tightness.

It is important that these structures are suitable for installation in heating systems. Otherwise, the use of unsuitable devices can lead to inefficient scheme Heating. It is important to explore the labeling on the pipe.

As for the boiler, there is an opportunity to choose. Not only gas, but electrical or solid fuel operating on solid fuel can be purchased. It all depends on the location of the house. The need for a collector system is explained by the fact that it is important to ensure the work of the entire water floor and maintain a given temperature.

Not in all boilers there is a built-in circulation pump. In such cases, it must be purchased separatelySince without it is impossible cycle of water. It is better to choose such a pump that has three speeds. The remaining parts for the arrangement of the warm water floor system are acquired on the basis of individual features Each device.

How to make heating with your own hands?

Preparation of the surface by aligning it

This can be done with a concrete screed or special compositionssold in construction stores. Next process base is recommended using primer. Do not forget about the insulation, which must be put on the prepared surface.

Laying thermal insulation

This process is not difficult, it is enough just to fix the joints of the assembly tape. From materials for insulation, there are such as foam plastic, polystroplane insulation. Best thick It is considered to be 5 cm. In some cases, when styling on the ground or with increased cold protection, thickness is allowed to 10 cm.

Laying pipes

The reinforcing grid is laid out, providing full fastening. The pipes themselves can be installed in the form of a snake or spiral. It all depends on the personal wishes of the host of the room, but the masters believe that the spiral installation scheme is preferable. With the first laying option, an uneven heating of the floor is possible. To calculate the width of the installation, many values \u200b\u200bare taken into account. These include wall thickness, pipe diameter and other factors. The optimal length of the pipe is 100 m, as the water cools, removing from the beginning of circulation.

Heating materials may be the most common water pipes, however, their service life will be significantly lessspecial devices. There are subtleties of plating pipes, which consist in the fact that the connection to each other needs to be carried out with adapters. In the event that metal-plastic pipes are installed, the metal surface must be removed within 3 cm from the start of the pipe.

The pipe is attached to thermal insulation with fixing connections. They are necessary to facilitate the floor mounting and guaranteeing the proper placement of the pipe. Fasteners can be plastic or metal elements.

It is important to know that for a warm floor you need to use only a solid piece of pipe. At the same time, the maximum length of each contour should reach 100 m. Otherwise, it will have to use too high pressure for optimal speed heat transfer.

Preparation and collector connection

Installation of this device occurs according to the instructions specified on the package. In each case, the installation process will differ due to the fact that there are many different models on sale. The correct arrangement of the collector box should provide the same water pressure in all circuits.

Mounting boiler

Often, during the connection of the boiler to the heap system, a problem is created, which is that the temperature of the water is several times higher than the water floor required. Therefore, it is important to make water with lower temperatures in the pipes. This is possible by diluting the water already cooled, which comes in the opposite direction.

The design of the heating must pass the assembly process consisting of the following scheme:

• Installing the control valve.
• Fixing the circulation pump.
• Mounting a collector.
• Ensuring the flow of water reduced temperature.
• Connecting the pipe to the boiler.

If the screed is used, the process occurs under pressure. Mixtures for a screed can be cement and sand, concrete or dry.

When using cement and sand, it is best to acquire ready-made means, which includes a special plasticizer. This element allows you to make a solution plasticand also increases the level of heating due to thermal conductivity. For concrete composition, it is recommended to acquire the cement of a special M-300 brand.

Dry materials include sand, various additions for heat expansion and to reduce air bubbles. During the last stage Works need to take steps to prevent cracks on time. There are two options here:

• When the room is divided into two halves, each of them is poured separately using a special tape. Further, all existing gaps are removed by shtlock.

• After drying the screed, the perimeter of the room is cut into sectors with the help of a grinder, and the seds formed are closed with silicone. Then they must be past.

In the design with a wooden floor, the whole process is much simpler, as it does not require the installation of the screed. It is enough just to cover the boards a special box where heating pipes are placed. An important feature is an proper placement pipe. The whole design is placed at the level below the boiler. This will contribute to free heating and cycling on plastic heating elements.

It is worth discreeting the issue of laying water underwear without a screed in more detail. There are many advantages, one of which is a small weight of the design, as well as the lack of the need to wait for cement drying. This is the heating system that allows you to significantly save money.. Installation of such a design requires the use of the foundation where the contours of the pipes will be laid. It can be wooden or polystyrene.

Also must be present from metal, which evenly distribute heat. You can equip the warm floors both under the tile and under the laminate, but in all cases you need to take care of good heat transfer.

To date, the installation system is applied using gypsum fiber sheets. They are laid as the basis, fill the gaps between pipe contours, serve top layer Under the selected coating. This design is easily disassembled, if necessary, repair. Moreover, hypus fiber lists Perfect warmly.

Another possible option for creating water floors without a screed is the use of aluminum sheets, in which there are already departments for laying pipe contour. But the masters note that the dry-fiber elements are much better in quality. The advantages of such materials are as follows:

• Availability of price.
• Simple scheme Processing.
• Safety.

From the ability to establish warm water floors do not need to refuse, since this system will greatly facilitate life due to the creation comfortable conditions Accommodation and savings for the purchase of energy.

Competently installed heat in the dwelling can be made without costly services of specialists. It is enough just to know the necessary subtleties of this process and choose the right equipment for heating.

Today, many owners of private houses are installed for additional or basic heating warm water floor. They have a lot of advantages: it evenly warms the room, increases comfort, does not require additional energy costs, because it works from one boiler with radiators. In this article, we will consider how to install a warm floor in a private house with your own water, not even having experience in conducting such works.

Preparation and calculation of materials

Such responsible work should begin with planning and prepare all the necessary materials. Strictly speaking, only experts who have information about the level of heat leakage in a particular room can be accomplished. But for individual needs, as a rule, approximate calculations are used, which are quite satisfying the requirements.

To begin with, it is necessary to draw the plan for the location of the pipes of the warm floor of water in a private house. Vividly and clearest things will be drawn on a sheet of a diagram on which the system can be calculated, based on the square square. Each cell will correspond to the same step, that is, the distance between the pipes of the system. The zone of moderate climate:

• With a fairly good isolation of windows and houses, the distance between the adjacent twists of the pipe can be made about 15-20 cm.
• If the walls are well insulated - 10-15 cm.
• In spacious rooms, where part of the walls are cold, and some are warm, variable moves: near the cold walls the distance between the adjacent turns of the pipes is not too large, but as they approach warm walls - It increases.

Choosing flooring for a warm floor:

• Those who are on the warm water floor are going to lay a thick wooden coating or parquet make a serious mistake. The tree does not spend heat, because of which it will greatly prevent the heating of the room. The efficiency of such heating may be even worse than the radiator, in turn, the cost of heating is quite large.
• The perfect coating for the warm floors is ceramic, stone or porcelain tile. Heating, she will be wonderful to keep warm, and this is the best option for the bathroom or kitchen. In the rooms where the warm floor is made - the children are very fond of playing, and just walking barefoot much more pleasant than on a wooden parquet.
• A little worst option for flooring, more appropriate for a bedroom or a guest room - laminate or linoleum. Such materials are well transmitted heat, without lowering the efficiency of water heat supply. At the same time, the laminate must be chosen minimum thickness, and linoleum - without a substrate with insulation.

Important! When heated, many artificial materials are able to allocate harmful evaporation into the air. That is why the flooring with chemical additives must have a product manufacturer's mark about the possibility of their use in residential areas on warm floors.

Base under the warm floor

If we are talking about housing with concrete overlaps, then the best option for the base under the warm floor of water with your own hands in a private house is a concrete screed with water heating.

Important! The same method is also used for the first floors (basement) private cottages if the base of the floor is on the sand pillow, which is located directly on the ground.

In homes, where there are wooden floors this option is not suitable. Wooden beams The overlap simply will not stand the big weight of the screed of concrete, whatever it is thin. In this case, a lightweight version of the warm floors is used, which we will talk about a little later.

Installation of warm floors with their own hands begins with thorough preparation of the base, which should be even, without any depression and protrusions. The maximum allowable drop can be 5 mm.

Important! If the depth of the surface defects has 1-2 cm, then you will have to pour, and then dissolve the thin layer of fine rubble (granite dropout) with a grain size of up to 5 mm. On top of the leveling layer, it will be necessary to put the film and in the process of laying thermal insulation walk along wooden panels. Otherwise, the leveling layer will serve as a source of irregularities.

Water warm floors laying schemes

The most common schemes for laying water warm floors - spiral and snail:

• Snail evenly warms the entire area of \u200b\u200bthe floor.
• But the helix can provide a greater level of warm-up in the coldest area of \u200b\u200bthe room. For this purpose, the first branches of the pipe, which will be served hot water, are laid out there.

According to a predetermined plan, the exact length of the pipe is determined.

Important! For warm floors, it is necessary to use only a solid piece of pipe. If the room is large, then several heating circuits should be planned. Moreover, the length of the pipe of each of these circuits should not exceed 100 m. Otherwise, it will be necessary too big PressureIt is necessary for the normal flow rate of hot water. By area, it approximately corresponds to 15 square meters.

Warm floor with water, with his own hands, in a private house, it is better to do from a metal plastic pipe, the diameter of which is 16 mm. It is easily nuts with a sufficiently small radius, and it is much more convenient to work with it than with a stitched polyethylene pipe. The pipes with a diameter of 20 mm are undesirable, because the large diameter will require an increase in concrete thickness, which will negatively affect the effectiveness of the heating system.

As a rule, the pipe flow per 1 square meter of the area is:

• 10 meters at a step 10 cm.
• 6.75 meters in step 15 cm.

Selection of thermal insulation and fasteners

So that the heat does not go down, it is necessary to lay a layer of dense foam.

Important! The density of the insulation should be chosen at least 25, and better - 35 kg / cubic meters. Lighter types of foam simply will challenge under the weight of a concrete layer.

Insulation and heat transferman

The optimal thickness of the insulation is 5 cm. When laying on the ground or, if necessary, higher cold protection, when the floor below is bad or unheated premises, the thickness of the heat-insulating layer can be touched up to 10 cm.

To reduce heat loss, on top of the insulation, it is recommended to use a heat transfer screen consisting of a metallized film. It can be:

• The reflective screen from the foam rubber, which is glued behind the radiators.
• Penofol (metallized foamed polyethylene).
• Normal food aluminum foil.

The metallized layer is rapid enough due to the aggressive effect of concrete, so the screen itself also needs to be protected. Such a protective layer will serve polyethylene filmwhich is often used for greenhouses in the greenhouse. The thickness of this film must be approximately 75-100 microns.

Moreover, it provides the necessary humidity for the ripening screed of concrete throughout the period of its frozen. The pieces of the film should be laid the flashes, and the joints of the connection thoroughly glue with scotch.

Fasteners for pipes

Top thermal insulation are installed fasteners for pipes. Their appointment is to fix the neighboring pipes of the pipe and place it on the floor with strict accordance with the preliminary scheme. The fasteners hold the pipe until the concrete screed acquires the necessary degree of hardness. The use of fasteners facilitates the installation of a warm floor by water with their own hands in a private house and guarantees correct location Pipes in the thick of the concrete pillow.

Fasteners can serve special metal strips, welded metal mesh, plastic brackets that fix the pipe to foam base:

• Metal strips are used with an enlarged thickness of the cushion from concrete. They lift the pipe in relation to thermal insulation, so that it turns out to be a little closer to the top surface of the cushion from concrete. Pipe simply snaps into curly excavations of the planks.
• Metal grid not only fixes the pipe, but also reinforces the layer of concrete pillow. The pipe is fixed to the grid using pieces of wire or plastic clamps. At the same time, the fastener consumption is 2 pieces on 1 raman meter. In places of rounds, you can use additional fasteners.
• Plastic brackets are mounted manually. They pinch the pipe to the foam on a measure of her laying. Semi-industrial warm floor is made using a special stapler. However, its purchase is justified only with intensive professional use.

Recently, manufacturers of warm floors began to offer another fairly convenient solution - special sheets of dense polystyrene foam with a profiled surface. As a rule, the surface of such sheets is the intersection of grooves or a number of protruding elements, between which the heating pipes are stacked.

The surface of such sheets is smooth, extruded, all the pores are closed, with an additional waterproof film for it is not needed. Having at its disposal a special thermosak, the grooves in the polystyrene can be made independently. However, at least a minimum experience is needed to carry out such work.

Important! Metal plastic pipes are supplied in the bays. In the process of laying the bay rolled along the trajectory of the pipe placement. It is impossible to pull the pipes from the underlying bay, as this will cause her twisting and can lead to the decoration of the inner layers.

Cooking and pouring concrete

It is possible to produce pouring pipes with concrete when installing a water warm floor with your own hands in a private house. It is possible in the private house only after they are fully laid, are properly connected to collectors, and also filled with a coolant under pressure of 4 bar.

Important! Before the fill, you need to withstand the pipe under pressure throughout at least a couple of days. If it is found to flow, it must be immediately eliminated. If the system itself is not yet installed, then instead of water in the pipes using the compressor, air should be loaded and fix the pressure with ball valves.

Immediately after the injection, the pressure may decrease slightly due to pipe straightening. In the process of filling and hardening concrete, the pressure is controlled using a connected pressure gauge.

In order to compensate for thermal expansions along the walls, damping tape is attached. The temperature expansion of the cushion from concrete should be 0.5 mm per straight meter, with an increase in temperature by 40 degrees. In the event that the heating is only 20 degrees, then the extension will be twice as smaller. You need to multiply the expansion on the length of the longest section of the concrete floor and compare the resulting value with a thickness of the damper tape.

As a rule, for ordinary houses, it is enough to put the tape only along the walls and doorway. Also, the damper tape plays the role of heat insulation of the warm floor and walls. In this way, cold bridges are eliminated, which cause unnecessary heat leakage.

In some cases, compensation seams are additionally made:

• If the length of any of the sides of the room is more than 8 meters.
• Floor area exceeds 30 square meters.
• Length and width of the room differ more than twice.
• The shape of the room has several bends.

For long warm sex, compensatory seam with damper tape is equipped every ten meters. To move the pillows from concrete in these places does not break through the pipe, it should be put on a rigid plastic corrugation or pipe big diameter. Sunset of the protective pipe into concrete pillows - at least 0.5 m with each of the sides.

If, according to the placement plan, there is a cluster of warm pipes in some one place, for example, near the collector, then the heat-insulator sleeve should be put on the pipe. This will give the opportunity to avoid local overheating, and also it is better to maintain heat for the desired sections of the floor.

Warm water floor concreting

If concrete for pouring a warm floor is not brought, but is done on the spot, then the following components will be required:

• Washed river sand - 1.9 V. h.
• Cements of the brand 300 (400) - 1 Weight part.
• Crushed stone 5-20 mm - 3.7 V. h.

Important! This is the composition heavy concretewhose weight is 2.5 tons per 1 cubic meter. m finished material.

But many refuse sand in concrete for warm floors. This is due to its low thermal conductivity. Therefore, in practice, cement-gravel mixtures are often used, the composition of which is as follows:

• Cement - 1 bucket.
• Granite crushed stone - 5-20 mm - 2 buckets.
• Water - 7 l (if the solution is very thick, you can add more 1 l).
• Small granite screening - 4 buckets.

Granite is remarkably conducting heat, and such concrete has significantly lower thermal resistance. In addition, the composition is to introduce a reinforcing fiber, which is small plastic fibers.

Important! The composition of any bulk sex must necessarily include a plasticizer. Its quantity depends on the brand and purpose of this drug. Moreover, the plasticizer should not be any, but intended for a warm floor.

General Filling Rules:

• If the pipe is fixed on a plank or brackets, then on top of it you need to put the reinforcing grid. And the height of the concrete screed should be selected 5-10 cm.
• In this case, it is necessary to provide at least 3 cm concrete above the pipe. A smaller layer can lead to cracking, and too thick cushion from concrete will increase the loss during heat transfer.
• For proper choice Concrete and an acceptable temperature he begins to grab already after 4 hours. For support normal humidity It must be covered with a waterproof film, and in the process of drying the surface - watering it with water.
• Already after 12 hours, the frozen concrete will be able to withstand the weight of one person. However, its full aging comes no earlier than in 28 days. All this time, it is necessary to take care of its humidity, as well as maintain a sufficiently high pressure in the laid pipes. Only after the specified time, the first thermal tests of such a floor can be carried out.

Important! As during the first test of the warm floor of water, with their own hands in a private house, and subsequently it is impossible to quickly heat it up to high temperatures.

Flooring

On the finished, fully dried concrete base can be glued to ceramic tiles or some other outdoor species coatings. This should use glue, which is designed for warm floors.

Important! If the tile falls just on the compensation seam, then one part should be glued, and the second is to put on silicone glue. Silicone absorbs thermal movement of the base, so that the tile does not crack from overvoltage.

Lightweight Warm floor for Wooden Overlap

As mentioned above, for wooden overlaps It is necessary to make a light warm floor without a concrete pillow. In this case, the sequence of work may differ slightly, depending on the design of the overlap and state of the old floor:

• So that the heat does not go down, under the pipes need to be laid insulation. It can be placed between the lags of the overlap, and then it is better to use Minvatu. And it can be laid on the old draft floor - there will already be needed polystyrene foam with a density of 25-35 kg / cubic meters.

Important! To prevent the formation of condensate, under the mineral wool it is necessary to put the membrane-parobarrier, and to fill the first draft floor from above on the lags.

• Also, as well as for concrete floor, a heat-reflecting screen from a foam or foil is recommended for insulation. At the same time, all seams and joints must be carefully cleaned by scotch.
• Directly on expanded polystyrene, the lags should be asked to whom the blackboard boards. At the same time, there must be gaps between the boards approximately 2 cm for styling the pipe.

Important! The same gaps should be foreseen at the ends of the floor boards. Otherwise - for the pipe will have to choose transverse grooves, and this can cause the breakdown of the boards.

• So that the heat is evenly distributed across the floor, the pipe must be laid not just in the groove, but in specially intended metal gutters that are intended for these purposes. Metal well transfers heat over the entire surface and evenly warms the finish coating. Tips on his choice were given a little higher - it can be a laminate that can work with heating, or hard polymer coating. Fat parquet for warm floors is less suitable.

Important! Compared to a concrete warm floor, a lightweight design is shutdown much faster and costs cheaper. Another advantage is the possibility of pipe repair work in the event of an accident. Problems with a pipe in the concrete floor can be eliminated only by means of its complete replacement. But the wooden floor also has a disadvantage - it is a significantly lower thermal power.

Competently equipped with a statenly water warm floor with their own hands in a private house - this is another step towards convenient and comfortable living conditions for the whole family. But even if for some reason you cannot fulfill these works yourself and are forced to invite specialists, the knowledge gained will help you take the most active participation in this process and control the quality of the system collected.

In the premises, the heating of which was made using the technology of the warm floor, the sensation is much more comfortable than with a traditional radiator system. When heating the floor, the temperature is distributed optimally: the warmer with all the legs, and at the head level is already cool. Ways of heating two: water and electric. Water is more expensive in the installation, but cheaper in operation, so it is more often done. A little to reduce costs when installing can be if you make a water warm floor with your own hands. The technology is not the simplest, but also does not require encyclopedic knowledge.

Device and principle of operation

For water heating of the warm floor, the pipe system is used for which the coolant circulates. Most often, the pipes are poured into the screed, but there are dry installation systems - wooden or polystyrene. In any case, there are a large number of pipes of a small cross section laid under flooring.

Where you can mount

Due to the large number of pipes, water heating is made mainly in private houses. The fact is that the heating system of high-rise buildings is not designed for this method of heating. It is possible to make a warm floor from heating, but the likelihood is that or you will be too cold or from the neighbors from above or below, depending on the type of system washing. Sometimes the entire riser becomes cold: the hydraulic resistance of water floors is several times higher than the radiator heating system and it can block the movement of the coolant. For this reason, it is very difficult for this reason to achieve a management company for the installation of warm sex (installation without permission is an administrative offense).

Good news is that two systems began to do in new buildings: one for radiator heating, The second is for a water warm floor. In such houses and permits, it is not required: the corresponding system was developed, taking into account the higher hydraulic resistance.

Principles of organization

To understand what you need to make a water warm floor with your own hands, you need to figure out what the system consists of and how it works.

Adjusting the temperature of the coolant

In order for the legs on the floor to be comfortable, the temperature of the coolant should not exceed 40-45 ° C. Then the floor heats up to comfortable values \u200b\u200b- about 28 ° C. Most of heating equipment It cannot be issued this temperature: at least 60-65 ° C. Exception - condensing gas boilers. They show the maximum efficiency at low temperatures. From their output to feed the heated coolant can be directly in the pipes of a warm floor.

When using a boiler of any other type, a substrate node is required. It adds a coolant from the return pipeline to hot water from the boiler. The composition of this Uza you see on the heat-mall connection scheme to the boiler.

The principle of work is next. The heated coolant comes from the boiler. It enters the thermostatic valve, which, if the threshold temperature is exceeded, opens the heating of water from the return pipeline. In the photo before the circulation pump there is a jumper. It establishes a two-way or three-way valve. Opening it and mix the cooled heat carrier.

The mixed flow through the circulation pump falls on the thermostat, which manages the operation of the thermostatic valve. When the specified temperature is reached, the feed supply is stopped, when exceeding it opens again. This is where the temperature of the heat carrier heat carrier is adjustable.

Distribution by contours

Next, the coolant falls on the distribution comb. If the water heated floor is made in one small room (bathroom, for example), in which only one loop of pipes is laid, this node may not be. If there are several loops, then between them it is necessary to somehow distribute the coolant, and then it is somehow assembled and sent to the return pipe. This task and performs a camshaft or, as elsewhere called, a heap collector. In fact, these are two pipes - on the feed and return to which the inputs and outputs of all heat-mall circuits are connected. This is the easiest option.

If the warm floor is made in several rooms, it is better to set a collector with the possibility of adjusting the temperature. First, in different rooms Required different temperatures: Someone prefers in the bedroom + 18 ° C, someone needs + 25 ° C. Secondly, most often, the contours have different lengths, and there can be different amounts of heat. Thirdly, there are indoors "internal" - in which one wall comes out, and there are angular - with two or even three outer walls. Naturally, the amount of heat in them should be different. Provide this comb with thermostats. The equipment is not cheap, the scheme is more complicated, but this installation allows you to maintain the specified room temperature.

Thermostators are different. Some control the air temperature in the room, the second is the temperature of the floor. Type choose yourself. Regardless of this, they control the servomotors installed on the feed comb. Servomotors depending on the command increase or reduce the flow cross section, adjusting the intensity of the coolant flow.

Theoretically (and practically happens) there may be situations when the feed on all contours is blocked. In this case, the circulation will stop, the boiler can boil and fail. That this does not happen, they necessarily make bypass, through which part of the coolant passes. With this construction of the security boiler system.

You can see one system options in the video.

Laying warm water floors

One of the key components of the system is pipes and the system of fixing them. There are two technologies:

Both systems are imperfect, but cheaper is laying pipes in the screed. Although it has a lot of minuses, it is she who is more popular for a reason for lower cost.

What system to choose

According to the cost of the dry system, they are expensive: their components (if you take ready-made, factory) are more. But they weigh much less and are put into operation faster. There are several reasons why you should use them.

First: big weight screed. Not all the foundations and overlappings of houses are able to carry out the load created by the water warm floor in the concrete screed. Above the surface of the pipes must be a layer of concrete at least 3 cm. If we consider that outside diameter The pipes are also about 3 cm, then the total thickness of the screed 6 cm. Weight turns out more than significant. And on top Often there is still a tile on the layer of glue. Well, if the foundation is calculated with the reserve - it will endure, and if not, problems will begin. If there is a suspicion that the overlap or foundation will not carry out loads, it is better to make a wooden or polystyrene system.

Second: Low maintainability of the system in the screed. Although when laying a heated floor circuits, it is recommended to lay only one-piece bays of pipes without compounds, periodically pipes are damaged. Or when repaired, got a drill, or burst due to marriage. The place of damage can be determined by the wet spot, but it is difficult to repair: you have to break the screed. At the same time, it is possible to damage the neighboring loops, because of which the damage zone becomes more. Even if you managed to do neatly, you have to do two seams, namely they are potential places of next damage.

Third: Commissioning of the warm floor in the screed is possible only after the concrete will drop a 100% strength resource. It takes at least 28 days. Prior to this period, it is impossible to turn on the warm floor.

Fourth: You have a wooden floor. By itself, trample on wooden floor - Not the best idea, but also a screed with an increased temperature. Wood will quickly collapse, the whole system will collapse.

Causes are serious. Therefore, in some cases, it is more appropriate to use dry technologies. Moreover, the wooden water warm floor is not so expensive. The most expensive component - metal plates, but they can also be made from thin sheet metal And better - aluminum. It is important to be bending, the dumps for pipes.

The variant of the polystyrene system of the warm floor without a screed is demonstrated in the video.

Warm water floor materials

Most often make water warm floor in the screed. About its structure and required materials And it will be discussed. The diagram of warm water floor is presented in the photo below.

All work begins with alignment of the base: without insulation, heating costs will be too high, and you can only lay the insulation on a flat surface. Because the first thing is preparing the foundation - do black screed. Next, we describe the turn of work and the materials used in the process:

• On the perimeter of the room rolled up and damping tape. This is a strip heat insulating material, no more than 1 cm thick. It prevents heat loss on wall heating. The second task is to compensate for the temperature expansion that occurs during the heating of the materials. The tape can be special, and you can also put the cut thin foam (no more than 1 cm thick) or another insulation of the same thickness.
• A layer of heat insulating materials is placed on the black screed. For a warm floor device the best choice - polystyrene foam. Best is the extruded. Its density should be at least 35kg / m 2. It is tight enough to withstand the weight of the screed and operational loads, has excellent characteristics and long-term operating time. His drawback is the roads. Other, cheaper materials (foam, mineral wool, Ceramzit), have a lot of flaws. If you have the opportunity - use expanded polystyrene. The thickness of thermal insulation depends on many parameters - from the region, characteristics of the material of the foundation and insulation, the method of the organization of the draft floor. Therefore, it must be calculated in relation to each case.

• Further, we often put a reinforcing grid in a step of 5 cm. It also ties pipes with wire or plastic clamps. If expanded polystyrene was used, it is possible to do without reinforcement - it is possible to mount with special plastic brackets that drive into the material. For other insulation, the reinforcing grid is required.
• On top set lighthouses, after which they pour the screed. Its thickness is less than 3 cm above the pipe level.
• Further, the finishing floor covering is stacked. Any suitable for use in the heated floors.

These are all the basic layers that need to be put when you do a water warm floor with your own hands.

Pipes for a warm floor and laying scheme

The main element of the system is the pipe. Most often polymer - from stitched polyethylene or metal-plastic. They are well bent, have a long service life. The only obvious drawback is not too high thermal conductivity. This minus has no recently corrugated stainless steel pipes. They are better, it is not more expensive, but because of a small fame, it is rarely used.

The diameter of the pipes for the warm floor depends on the material, but usually it is 16-20 mm. They are stacked in several schemes. The most common - spiral and snake, there are several modifications that take into account some features of the premises.

Laying the snake is the most simple, but passing through the pipes the coolant gradually cools up and the end of the contour reaches the much colder, which was at first. Therefore, the zone where the coolant comes will be warm. This feature is used - styling starts with the most cold zone - Along the outer walls or under the window.

This lack is almost deprived of a double snake and a spiral, but they are more difficult in laying - it is necessary to draw a scheme on paper in order not to get confused when laying.

Screed

It can be used to fill the water warm floor. An ordinary cement-sandy solution based on portland cement. Portland cement brand should be high - M-400, and better M-500. - not lower than M-350.

But ordinary "wet" ties are typing their design strength for at least 28 days. All this time, turn on the warm floor is impossible: cracks will go, which can even break the pipes. Therefore, it is increasingly used by the so-called semiflue ties - with additives that increase the plasticity of the solution, significantly reducing the amount of water and time to "aging". They can be added independently or seek dry mixes with the corresponding properties. They are more expensive, but the carrots are less: according to the instructions add the required amount of water and stirred.

Water warm floor do it yourself actually, but it will take a decent period of time and considerable means.

Make a water warm floor with your own hands in a private house under the power to any home master. We will take patience, carefulness, purchase of materials and missing tools. As a result, you will receive a system that allows you to adjust the heating level throughout the floor. Consider the advantages and disadvantages of the water circuit, the policy of the material selection, installation scheme, laying and connecting.

Advantages and disadvantages of a warm floor

Filing towards the complexity of the installation, the masters agree that the water heated floors in a private house - one of the most effective systems Heating. In comparison with the radiator system, water floor in wooden house It can give substantial savings to heating costs due to uniformity of heating throughout the area. Additional advantages:

1. Low-temperature mode. This means that the air in the room will not be cut, it will not be stuffy.
2. No overheating of air mass.
3. Water heating of the floor meets the requirements of environmental safety, sanitary and hygienic standards.
4. There is no negative effect on a person, since most of the energy is transmitted by thermal radiation.
5. The device of water warm floors in a private house with ceilings height from 3r m gives savings up to 30%.
6. Mounting system hidden - it simplifies processes interior decoration premises.
7. Safety. Mounting the warm floor from heating in a private house, the user does not risk getting a closure in electrocups, as in the case of electric floors - The whole system consists of pipelines, ordinary water is used as a coolant.

Water floor disadvantages:

1. Labor consideration. Presenting a system of several layers of material, the design requires careful preparation and compliance with the installation scheme.
2. The risk of leakage. To search for the leaking link will have to raise all the laying.
3. Unwanted weighting constructive features Buildings. The layer laying of materials increases the mass of overlaps by 10-15%, so the seating of a warm floor with their own hands on the 2nd and above floors, you need to calculate permissible load On the overlap.

It is extremely important, equipping the heating system by floor, perform high-quality insulation Buildings. In this case, making a water warm floor with your own hands, you will not have to complement the heating by convectors.

Design

Before drawing up the project, you need to make sure that nothing hurts the idea of \u200b\u200bthe idea. What to pay attention to:

1. The height of the room. The thickness of the entire system of warm floors in a private house from scratch is 10-12 cm.
2. Door outs. Raising the floor level, it is important to maintain the height of the opening. You will have to estimate the price of the door to order or the possibility of increasing the doorway in height.
3. Location / orientation of windows. If they go to the windy side, north / west, the system power should be increased.
4. Estimate carrying ability Ball overlap. The weight of the entire system with a concrete tie significantly increases the load.

Refusing heating is not necessary, one can consider the option of the oscillation (dry) water floor. The system is pipelines with a carrier laid out on top of the board. In this case, you do not need to mount the screed, it is enough to install on top of the draft floor wooden framewhose height will be equal to the thickness of the insulation. To put or fall asleep insulation (sheets of minvati, ceramzite, sawdust), on top to lay the boards, in the seams between which and hide the pipes with the coolant. From above, the falsefield can be faced with finishing finish.

Schema Development

The scheme is developed taking into account the parameters of the room, technical characteristics Equipment and materials. To make the calculation, indicators and data are determined:

• floor area;
• room height;
• wall material, overlap;
• type of thermal insulation;
• type of finishing flooring.

You also need to think about the desired T ° mode. For convenience of calculations, we present a table with indicators of the limit T ° mode for the premises miscellaneous destination:

/> />

Type of room	t ° mode (maximum)
Residential space and premises where people spend time standing	21-27⁰.
Rooms for sitting people, offices	29⁰.
Hall, corridors, halls	30⁰.
Bathrooms (pools)	30-33⁰.
Active pastry	17-19⁰.
Premises where stay is limited	37⁰.
Regional zones of any premises	35⁰.

After refinery, the scheme is drawn up in which the following data contains:

1. Installation points and heating radiators dimensions, if any.
2. The layout of the pipes with the size of the diameter and the length of the direct sections.
3. The distance between the elements, T ° media parameters in each pipe and the length of all circuits.
4. Power data for heating each individual room. The radiator power is calculated, taking into account the location and length of the pipeline, to it connected.

Also in the diagram you should specify the data on the configuration of the automation.

To install the floor of water has passed successfully, making up a scheme, listen to the advice of professionals: the pipe diameter affects the maximum length of the calculation. For pipes 16 mm - up to 100 m, for pipes in 20 mm - no more than 120 m. The parameters are needed to ensure optimal pressure inside the warm floor system. If the scheme of mounting a warm floor of water is provided by several contours, it is easier to make them the same length with a maximum difference of 15 m. Pipe laying step should not be more than 30 cm in the center and 15 cm around the edges. In regions with severe winters, it is recommended a pitch of 10 cm. The location step affects the pipe costs. Calculation is done like this: with a step at 10 cm, 10 m pipes are required on m² of room area, with a step 15 cm consumption will be 6.7 m / m². When laying the circuit in the diagram it is necessary to bypass the zones of the installation of sanitary devices and heavy furniture. One outline overlaps the room not more than 40 m², the maximum length of the side of the circuit is up to 8 m. Thus, in the field of flooring in a private house, it is important to consider:

• limits of the page layout of the pipeline;
• limits and magnitude of the contour;
• heat insulation material in step decreased zones.

The step is always reduced in the opening area, and in the calculation scheme it is necessary to take into account necessarily.

Calculation

Standard formula for calculating the length of the contour: Active heating area (sq. M.) It is divided into the calculation step (m) plus the distance to the collector and the length of the bends. To get more accurate calculations, it is better to contact the specialists, but it requires investing money, so we make a water warm floor in the house in gradually do it yourself.

Tip: "To adjust the degree of heating of the coolant, thermostats are mounted. Maximum gradation on devices 55 °.

Detailed calculation scheme:

1. An indentation of walls from 30 cm.
2. The determination of the number of contours is calculated along the length of the pipe on the contour. When dividing the area of \u200b\u200bthe room to the display step, add 10% for turns. Formula: L \u003d S / N * 1.1. Designation L - the length of the pipe, S is the area of \u200b\u200bthe room, N is the display step. Thus, on an area of \u200b\u200b40 m² when laying up a pipe with a step of 15 cm, the desired definition of the length of the length of all circuits is 266 m.
3. When calculating the length of the contour to the collector (one end - to the feed device, the second - to the opposite), multiply the final figure by 2, and the desired length of the pipe from the point of connection to the collector.
4. Pipeline material: For a polyethylene diameter of 18 mm length up to 120 m, metal-plastic - no more than 125 m. The wizards do not recommend making contours of more than 90 m to provide the optimal resistance of the hydraulics and the load on the coolant.
5. In a step of 30 cm, a pipe is required 3.4 m / m²; step in 25 cm - 3 m / m²; 20 cm - 5 m / m²; 15 cm - 6.7 m / m²; 10 cm - 10 m / m².
6. If the area is from 40 m², the laying scheme is such: 3 contour of 100 m long, it is easier to provide the same warming over the entire area.

Tip: "The contour length is counted from the point of exit from the collector, and not in the area of \u200b\u200bthe entrance to the room where the system is mounted."

And now about how to calculate possible heat loss. The formula is complex and requires measurements of heat transfer of all nodes and house designs, the average precipitation, T °, \u200b\u200bair directions and other things. There are averages for which the owner of the house can navigate:

1. In well-insulated structures with installed hermetic glass stacks of heat loss are 40 W / m².
2. In unstary houses with an average service life of the thermal insulation of walls, windows, the door is 70-80 W / m².
3. In the buildings of the old type with windows made of wood, without insulation of heat loss, 100 W / m² and more are reached.

Tip: "If heat losses The buildings are greater than 100 W / m², the installation of water warm floor becomes inappropriate. "

Selection of components

For the manufacture of a warm flooring system in their own house, you will need the next set of materials: a boiler. As a rule, they make water floors from the gas boiler. It is profitable economically and easier by technology. The gas boiler power indicator should exceed the sum of all the power of the floor system by 15-20%. Another option is the electric water floors. Convenient for laying, but unprofitable due to the high cost of electricity. Circulation pump. The device will provide the normal movement of the carrier by pipes. There is already a pump in the boiler, but it copes with the load if the area of \u200b\u200bthe house does not exceed 100 m². Pipes. The choice is:

• copper - durable long time operation, but high cost;
• metal plastic - durable, bent, inexpensive and weigh little;
• polypropylene - low price, high limited heating, but high risk to buy fake;
• PEX - stitched polyethylene tube - reliable option if the mount is rigid, and the step is minimal.

The calculated cross section of pipes for dry water warm floors is considered to be the size of up to 20 mm. The expenditure rate of 1 m² (step in 200 mm) is approximately 5-6 m. The insulation. Here is the choice of this:

• foil polyethylene is suitable for minimum floor thickness;
• polystyrene foam in finished mats with protrusions for laying up pipes in 50 * 50 mm increments;
• mineral wool is cheap, but impractically due to the ability to absorb moisture from the solution.

Tip: "The layer of thermal insulation over basement The private house is always thicker. It all depends on the carrier required T °: the indicator above, the greater the insulation layer. "

Heat consumption counter. The device is needed for apartment buildings where the warm water floor is laid. Cabinet. It is necessary for mounting the elements of regulating and docking the contours of the pipe with the highway of heat supply. Reinforcing grid. The element helps strengthen concrete screed After the pipes are laid, but it is possible not to use reinforcement. Also required components for arranging a screed:

• screed solution (cement, sand, water);
• 10-15 cm width damper;
• fasteners for fixing the pipe.

The number of elements will prompt the pre-compiled scheme of warm water floors from the gas boiler. If the planning works are fulfilled correctly, there will be no errors. But the diagram itself should be saved so that in the event of a leakage to quickly remember all points of installation, fasteners.

Technology performing work

To make water floor, installation technology provides a phased algorithm for work:

• collector installation;
• the preparation of the floor with the layout of the damper tape, insulation;
• output contour;
• connection with tightness testing;
• crimping;
• tie

After completion of the preparatory stages, the system starts to work, then disconnected and one can end the arrangement of the floors of the finish finish.

Installation and installation of collector cabinet

By installing the water heating floor, it is extremely important not to skip the stages of work. Step-by-step instruction in warm floors It implies a detailed consideration of technology, difficulties will not even have a novice master. The collector wardrobe - the device where there is:

• collector;
• pump;
• air vent valve;
• drain removal.

The dimensional parameters of the device depends on the general configuration. When choosing the unit, you must calculate the installation zone - it must be equal to all contours. There is no possibility to fulfill the condition, put the collector next to the longest pipeline.

Important! When installing the warm floors in the collector installation zone, it is necessary to provide a zone for the trigger bend. Pipes are placed only from below to ensure the normal movement of the coolant. Install a stop valve between the circuit system and the collector is necessary for preventive service and repair construction.

Preparation of base and laying insulation

To make heating under the floor in a private house, you need to spend preparatory work based:

• clean the base from garbage;
• remove the height differences, the equalizer plane as possible;
• lay the selected thermal insulation material;
• waterproofing is laid on the heat insulation (dense film);
• along the walls damper tape, which will eliminate the effect of thermal expansion of a concrete screed.

Equal thickness of warm floors is necessary for high-quality warming up the entire surface, therefore, the better the plane is aligned, the evenly layer the screed layer.

Contour device in different ways

Thinking on how to make a water warm floor, you will have to take into account the area of \u200b\u200bthe room. From this depends on the location of the pipes:

1. Snail. The contour of warm floors is laid out from the heating boiler of a private house around the perimeter of the room, going to the center with layout through a row. Such a scheme provides a quick refund of the coolant and increases the uniformity of the heating area. Masters prefer "Snail" in rooms with complex formWhere it is necessary to shift the center of the pipe and indoors from 40 m².
2. Snake or loop. This laying of pipes for warm water floor is performed from the collector along outdoor Wall (one), then waves refunded back. Good layout for rooms of a small area.
3. Mandrel or double snake. The combined calculation scheme implies parallel location of the contours. This option organizes the movement of the coolant with different T °, \u200b\u200bcompensating for the return of heat.

Important! Laying pipes of water warm floor always starts from the external or cold wall of the room.

To facilitate the task of calculating the newcomer, you should draw marking on the floor. Installation of a system of unreliable compounds or pipe segments is not allowed - this design will not stand the long heating season.

How to make a warm floor:

1. The floor mounting begins with connecting to the feed collector. From the wall you can retreat only 7 cm, but it is necessary to take into account the small layout step at the outer walls. This is required to reduce heat loss.
2. As soon as the pipe is laid throughout the contour, it must be fixed by the clamp. Dowels are suitable if they are tied to the pipes with wire. Another option is to put on the floor reinforcement grid, tieting the contour from the pipe to it; This levels the expansion of materials when serving heat.

Tip: "Ribrant polystyrene substrate, laid down under the contours of the system, will increase the thermal insulation indicators and will help mount the warm floor with their own hands, with the preservation of the desired step."

Connecting collector

It is simple: the free end of the pipe that remains after the output of the contour connects to the return collector. In order not to make a mistake, you should first read the instructions for the aggregate.

Pressing

This is the name of the hydraulic test process required to verify the quality of the calculation. If we make a warm floor in a private house, the crimping will help you adjust the order of laying and other nuances. Pressing is the launch of the coolant to the system under the highest pressure. The pressure level must exceed the calculated minimum of 1.5 - 2 times (from 0.6 MPa). What to watch with crimping:

1. Half an hour after launch, the decrease in allowable pressure is possible by 10%, not more.
2. The second half hour - the indicator should not decline more than 2-15% of the initial designation.
3. T ° media must remain unchanged.

Total check time - day. It is better to give the stage to 2 days to make sure that step-by-step mounting Water warm sex is done correctly, the floors are evenly warmed up and there are no leaks, breathed fasteners and other defects.

Screed

Instructions for the installation of warm water floor implies a screed from cement-sand mixturewhich is well conducted warm or classic concrete. For the manufacture of concrete, cement brands from M300, water, sand and 3-5% plasticizer are taken.

The thickness of the screed is 3-7 mm. You need to pour the finished solution to the contours filled with the coolant. In this case, the system operates in the mode specified during crimping. Concrete drying time up to 28-30 days, the period for the finished mixture you need to look at the package.

Tip: "If you need to make flooded floors in a private house with an area of \u200b\u200b40 m², you must necessarily provide compensation seams."

First start

The procedure is carried out only after dried and scored the strength of the screed. Now you can turn on the collector and drive the heat carrier on the heating pipes of warm water floors. At first, the t ° is + 25 ° C, then increases 10 ° C every day. The desired parameter Warming up with a gradual increase in T ° system dials in 2 days.

Finishing

Knowing how to make warm floors yourself, will not work to decorate them. Warm floor is stacked under the laminate, carpet, wood massif, under the tile - in a private house the last option is the most convenient. But if the installation scheme remains the same under the tile, then the laying requires a special approach to laminate:

1. Laminate must be high quality. The material during heating allocates volatile substances, the fake will be inappropriate. It is better to watch the label "Warmwasser" - this is a decor for floors with a water warm floor.
2. Under the laminate, thermal insulation and waterproofing materials are not stacked.
3. To ensure ventilation, on the perimeter of the laminate layout, a compensation gap of the width to 15 mm is left. Then the gap is overlapped with floor plinth.
4. Before laying the dice, you need to decompose the laminate on the floor, leaving the water contour warm. It is necessary for a set of T ° - the lamellaughters warm and easier to lay them.

Despite the lack of difficulties, the masters infrequently make water warm floors under the laminate. Lowhells are characterized by low thermal conductivity, in the tile it is higher, moreover, any dies are made using chemicals. In this case, the tile is much more practical.

Operating Rules

Knowing how professionally make a water warm floor in the house, it will be useful to follow the rules for use. Requirements are simple and available:

1. Warm floors in a private house, the wiring of which is made in compliance with technology, always type t ° gradually. Running outline at the maximum mark after a long downtime, the owner will receive a reduction in service life.
2. The increase in T ° mode must be gradual, not more than 4-5⁰s per day.
3. The indicator of the T ° of the incoming coolant is not higher than 45 ° C.
4. Frequent launches and disabling the system are fraught with rapid wear, but not reduced costs.

To enjoy heating with pleasure and without health damage, it is recommended to support optimal mode humidity.

There are no special difficulties in the design. And knowing how to make a warm floor in a private house, the owner will be able to install and on the street, for example, on the entrance area, stairs, car parking.

Before each owner of a private house is a question of choice. optimal view heating that will not only adequate its functions, but also to harmonize with modern design. Bulky radiators of heating morally outdated, worsen the interior of the room and dried air. An alternative is a water warm floor, for a private house is the most efficient option.

What is water-free floor

We bring to your attention not only a list of component materials, but also the principle of their choice.

Pipes.For floor heating flooring, plastic or metal-plastic pipes are used. Recently, the recognition of plumbers received pipes made of stitched polypropylene, which differ from other pipes highly resistant to deformation, excellent thermal conductivity and a high degree of tightness.

An important condition when choosing pipes is suitability for use in heating systems. Unfortunately, some unscrupulous sellers, using the client's incompetence, sell pipes intended for water supply. The result is an inefficient heating system. To avoid this, you need to watch the labeling that is available on each pipe:

• linear expansion of not more than 0.025 mm / m;
• heat consumption from 0.43 W / m 0 C.

The required amount of pipe depends on such indicators as the installation step and the diameter of the material. Look more in the table.

Boiler.You can purchase gas, electrical or solid fuel. The choice will be due to the residence region. For example, if there are interruptions with power supply, it is better to buy a gas boiler. If we talk about power, it depends on many indicators. For a standard house with insulated walls, plastic windows and a ceiling height of at least 3 meters, the following calculation is made: the specific power per square meter must be 100 W or 1 kW at 10 m 2. Knowing the total area of \u200b\u200bthe house, you can calculate the power of the boiler. It is better to turn on the supply of power, about 20%.

Collector.Provides the performance of the entire water floor and supports the temperature set by the thermostat. It is best not to save, but buy a collector consisting of a duct sensor, a drain crane and crane of Maevsky (whipsing the air flowing). Additionally, you will need to choose a shield.

Circulation pump.It is purchased if it is no longer built into the boiler. This device provides water circulation in the system and can be equipped with a thermostat that will control the water flow rate and, thereby adjust the temperature in the system. Perfect solution - a three-speed pump with a thermostat (installation of a temperature controller will require knowledge in the field of electrical engineering and not everyone forces). To learn how to choose a pump for performance, can be from the table:

As for the company, then preference is better to give european manufacturers. Excellent proven itself german company Grundfos.

Accessories.Implied couplings, threads, fittings, ball Valves etc. The amount required by their quantity is calculated individually, based on the characteristics of each water heating floor system. Heating of the floor in each specific house has to be calculated and planning individually.

Read also about, which will help seriously reduce the cost of heating.

Installation of water floor

First of all, you need to inspect the old floor. Linoleum, parquet, boards are subject to dismantling. On the tile, if it is strong enough, you can retain plastic pipes without pouring a rough screed.

A black screed, otherwise it is called "primary", serves for the maximum dense laying of thermal insulation. Therefore, at this stage, you can hardly not worry about the level of the floor and the presence of small irregularities. There will be enough concrete layer with a thickness of several centimeters. For these purposes, the M-300 grade cement is suitable, mixed with sand in the ratio of 1: 4.

The next step will be the laying of thermal insulation. There is nothing difficult here, it is worth only to pay attention to the joints between the material. They need to fix the assembly scotch to avoid unnecessary heat loss.

Material for insulation may be different:

1. Styrofoam. Although it is considered a morally obsolete insutiator, perfectly copes with the task assigned to him. The only drawback is short-life.
2. Penropopy insulation with foil reflective layer.
3. Heater polystyrene foam for a warm floor. This material is best suited for insulation. Having high density, polystyrene foam (otherwise penurex), perfectly isolates the water floor from the cold concrete base. Polyurex 35 can be used, which is resistant to ignition.

The last step will be the installation of a reinforced grid with a 5 mm reinforcement cross section and with cell sizes of 10-15 cm. It will be possible to secure the pipes for it using plastic ties. Moreover, reinforced grid Serves as a binder design for concrete floor. Or you can select special mats for water floors.

Secrets of Masters when installing Pipe for heating floor

The work itself does not have any particular difficulties, but there are a number of nuances, the knowledge of which will help to carry out the installation correctly.

Selection of laying scheme.Two ways of laying are known: snake and snail (spiral). Last option preferable. The fact is that when laying the pipe "Snake", the water temperature decreases by the end of the hinge, which entails the uneven heating of the floor. The location of the pipe helix will help this avoid: the floor warms up uniformly. At the same time, the material requires significantly less.

What length should there be a pipe?Regardless of the power of the selected boiler, the water will cool, as it removes it from the point of receipt. Therefore, the recommended pipe length is 100 m. In case you need more importantUse several contours, each of which is connected to the collector separately.

How to calculate laying step?To accurately calculate the step can only an experienced designer: to obtain the correct value, many factors are taken into account, from the thickness of the walls and size of windows, up to the diameter of the pipe. However, there are averaged data that we will operate. The optimal laying step for the system, which is the main source of heat in the house, is 10-20 cm. This value is not constant. Near the outdoor walls, the first 5-6 rows are stacked in 5-6 cm increments, closer to the inner walls and the middle of the room the step increases to the above data.

Today, construction stores have special mats for warm water floors, which greatly simplify and speed up the process of laying pipes. Look at the photo as it works.

Application of mats for warm water floors

How to solder pipes?This issue also has several subtleties that need to be illuminated within the framework of the article:

• connect pipes with each other, better through special adapters (otherwise barrels);
• if soldered metal pipes, then the metal shell must be removed at a distance of about 3 cm from the edge of the pipe.

To achieve high quality connections, you must be guided by the following table.

Assembly, installation, collector connection

It should be noted that the process of assembly collector will differ depending on the model, the number of heating circuits selected components. In order for the system to function without complaints, the assembly must be carried out according to the instructions attached to devices.

Where to position the collector?When choosing a place to mount a collector box, you need to take into account the equivalent removal from all circuits. It is necessary to ensure uniform water pressure in all circuits. If the wall on which is installed collector cabinet, not carrier - can be made in it niche.

How to assemble a collector?

Consider the assembly process on the example of the ICMA UPS model. In this case, we will take into account that the circulation pump and the collector itself is used together, it will provide simplicity of heating control.

1. We set the circulation pump on the cape nuts, gaskets are needed between the nut and pump.
2. We connect the collector with the pumping group, winding adapters with a cape nut and not forgetting about gaskets.
3. The mixture unit must be connected to the thermostat and the valve responsible for entering cold water (mixing).
4. Connect the mixing group to the collector.

Now the collector can be installed in the mounting cabinet, connect the feed and reverse to the distributor, then connect the elements of the heating circuit using adapters.

Installation of the boiler: Features, sequence

When connecting the boiler to a warm floor system, a problem often occurs. The fact is that the boiler gives the water temperature in 75-80 0 C, and for normal operation of water underfloor floor, a temperature is required not more than 45 0 C. For this reason, the connection must be performed in such a way that water with a reduced temperature is supplied to the pipes. Make it in closed system Heating can be only one way: dilute hot water The cooled coming from the "Furning". This function is performed by the underground shelter node.

Heating of the floor when installing must be assembled according to the following scheme, ranging from the boiler:

1. At the beginning of the circuit, the control valve is installed, then the circulation pump and the collector.
2. Between the valve and the pump, the submersion assembly is mounted in such a way that the cooled water from the "inverter" entered into the flow and then, through the circulation pump to the heating system.
3. Final stage - Summing up the reverse tube to the boiler.

It should be remembered that the principle of installing the boiler itself will differ from different models and types of equipment.

Pressing and trial launch

After the end of the installation work, you need to test the system. For this conduct crimping.

Check the tightness of the system in two ways: water under pressure or compressed air. Preferably the first option: after checking on tightness, you can immediately turn on the heating. Air inspection is used in the case when heated floors work from central heating, And there is no confidence in its timely inclusion. In any case, the pressure must be no higher than 6 bar. The system is considered to be operational if for 24 hours the pressure indicator has decreased no more than 1.5 bar.

After testing for tightness, you can hold a complete launch. The water temperature must be about 80 0 s, for this, the submersion node must be disabled. At such a temperature, the stress in the pipes is reduced, which ensures the durability of the structure.

Conclusion

You need to pour a concrete screed after the water in the pipes finally cools. For a screed, it is possible to apply both traditional concrete and a warm-alone solution with a higher ability to carry out heat. The thickness of the layer should not exceed 7 cm.

After the final drying, the screed can be drilled outdoor coating.
