Today, water warm floors are a very popular option for the heating of private houses. This design has in addition to the high efficiency of the set of advantages, among which the possibility of cardinal change in the interior, by delivering it from classical radiators. Despite the lot of advantages hydraulic system Heated floors has one significant disadvantage - the complexity of the installation, which increases the estimated cost of water heating in a private house at times.

Cheat this system Heating (CO) can be if all the steps of creating their own for their own. This publication will consider issues related to the preparatory work and the creation of a hydraulic heated floor with their own hands.

Preparation of the foundation

Proper preparation of the surface for laying a warm floor coil provides half of success when implementing this room from a private house.

• If the base is the slab overlap, then preparatory work Include surface cleaning, leveling cement-sand or specialized mixtures. If the base surface is wooden, then the superior algorithm is the following: cleaning from dirt and garbage, stuffing plywood or chipboard for alignment. If the styling of the coil on the ground is planned, then the operations are pre-carried out: creating a layer of sand and rubble, a tamping of vibrating tank, alignment. In some cases, it is recommended to create a draft reinforced base.

The second phase of the preparation of the base is waterproofing. Heating in the floor in a private house cannot be carried out without the appropriate waterproofing layer. Materials for its creation can be: mastic, bitumen materials, plastic film, thickness of at least 100mk.

Important! After laying waterproofing throughout the perimeter of the room, a damping tape is made, which compensates for the heat expansion of the floor when heated.

The third stage is insulation. This event is intended to ensure that the heat from the serpent is not increasing the floor.

Tip: If you plan to organize this CO, only as an additional, then it is enough to apply the substrate under the warm floor of water from foamed polyethylene with a foil coating. If the warm floor is planned over the heated room, then polystyrene sheets, 50 mm thick, are used as insulation. If the water heated floor is created on the ground or over the non-heated basement, then the layer of the insulation must be from 50 to 100 mm.

• The fourth stage of the preparation of the base is reinforcing, which is necessary for fastening the pipeline and fixing the screed. The thickness of the screed for water heat varies from the design and materials. The optimal thickness of the "cake from 70 to 130 mm.

  Construction I. composite elements Systems

  Consider the classic Warm floor circuit with a connection to the autonomous heat generator. This design comprises:

  1. Bootaging.

     Important! It should be understood that the temperature of the coolant in the central CO varies from 70 to 90 ° C. In order to avoid the output of the contour, the connection to the central pipe of heat supply is not directly recommended. Even if the pipeline material and fittings will hold out high temperature, Think about comfortable movement on the floor with a temperature above 60 ° C!

  2. Expansion tank closed type.
  3. Manometer.
  4. A pump providing circulation of the coolant in the circuit. This device can enter the design of the boiler installation.
• Skeins pipeline.

In addition, for independent creation Water warm floor will be needed: ball valves installed at the inlet of the heat generator; circulation pump (can enter the design of the boiler unit); Pipes and fittings for laying the route and connecting the coil to the collector, the number of which is calculated individually, based on the scheme and the design of this CO.

The circuit of the heating floor can be connected from the autonomous heat generator (gas electric or solid fuel). If the house has heated from the central heat supply, then if you have permissive documentsIt is enough just to connect a warm floor from heating with your own hands. Recently, a boiler is quite popular sources of thermal energy indirect heating or flowing water heater.

The main conditions for using a source of heat is sufficient performance, efficiency and safety. The required power of the boiler unit can be calculated according to the algorithm: on heating 10m 2 brick private house with double plastic windows, 1 kW of the power of the heat generator is necessary.

Tip: Not all houses are insulated on European standards (heat loss no more than 40W / m 2). In addition, much depends on the region of residence. Based on this, for houses in the northern regions and poorly insulated buildings, experts recommend increasing the calculation capacity heating Installation by 20-30%.

Pipe

The material for the creation of a water warm floor, when heating a private house, are: metalplastic, reinforced polypropylene or stitched polyethylene. Recently, the recognition of specialists deserved polyethylene pipes that do not have high values \u200b\u200bof linear expansion during heating, have good tightness and thermal conductivity. The diameter of the pipe should be within 16-20 mm. In addition, the pipe for water floor must have the following characteristics:

• Thermal conductivity of more than 0.43 W / m 0 s;
• Expansion coefficient not higher than 0.025 mm / m;
• Working pressure - 10 bar;
• Operating temperature 95 ° C.

Calculate required amount Pipes can be in the table below:


Pump

As already written above, the circulating pump, today, most modern heat generators are equipped, and it is necessary to purchase it only if it is not in the equipment.

The main condition of choice this device is performance. Correctly select the circulation pump on the table below:


A reservoir for heating and a warm floor is a nozzle with a certain number of taps. This splitter is designed to connect several heating contours (including a warm floor) to the supply and reverse line of the autonomous line. In this design, two such devices are applied: one - for the distribution of hot heat carrier, the second is to collect chilled water from the conserve. The collector also includes airlighteners, the necessary valves and cranes intended to adjust the performance of this CO.

When choosing this device, it is necessary to determine the number of taps sufficient for all heating circuits. If you are willing to pay for the full automation of the heat-loading process in accordance with the CO, then pay attention to the models equipped with servo drives on the valves and mixers. You should not neglect the collector box, the dimensions of which are selected in accordance with the size of the entire equipment included in the collector group.

For a clearer understanding of the collector assembly process, we recommend reading the video

Warm floors are now one of the most common ways to create heating a private house, because it can act as independent heatingEven in, and relieve you from bulky heating.

1. Water;
2. Electrical, which, depending on the type heating element are divided into:

• film;
• rod;
• cable.

According to the method of heating electrical systems are divided into:

• convection;
• infrared.

The creation of warm floors in the house significantly reduces, as you can include every heating circuit separately. Thus, you can simply turn off the unused premises from heating.

Principle of water floor scheme

In a private house, under the floor, it is paved along a parallel or spiral laying scheme. In the tubes, water circulates, which transmits and evenly distributes heat to the material laid near them. All this is heating the floor. The choice of material transmitting heat depends on the floor.

Installation plan

Before mounting heating in the floor, you need to draw a plan - the grid on which the whole will be reflected heating system. When applied to the plan for the plan for laying water pipes and planning the layout of the heating circuit, it is necessary to take into account that:

• between the pipes and the wall should be a distance of 0.2 - 0.25 m;
• interval of the interlocking gap - 0.35 - 0.5 m;
• the pipe deploying from the riser is stacked along the window;
• the density of pipes increases in the outer walls, and decreases to the center of the room. For example, the distance between pipes at the door, windows and external walls - 0.15 m, on the rest of the area - 0.3 m;
• in any case, when installing, observe a step from 0.1 m;
• distance from contour to external Wall There should be no more than 0.15 m;
• the length of heating loops should be no more than 100 m.

By the manufactured drawing, you can calculate the required number of pipes. Note that to summarize them to the collector you will need about 2 m.

When choosing a hose diameter, consult with heat engineers.

Do not forget that the coolants do not need to be laid under the furniture. Think out this moment in advance.

Used materials for laying

To mount a warm water floor in you, you will need:

1. insulation material (polystyrene foam plates, aluminum foil;
2. pipe for water heating;
3. damper tape;
4. dense polyethylene and corrugation;
5. reinforcement grid;
6. cement - sandy solution or dry composition of the "bulk sex";
7. lights, fasteners, dowels, selflessness.

How to make the installation of concrete warm floor of water type

Considering complex design This system, it is important that the house has high ceilings, since the arrangement of a warm floor will eat their height of 8.5 cm at a minimum.

The layer layer of water concrete warm floor from the bottom up:

• heat insulator;
• reinforcement grid;
• concrete with heating contour;
• cardboard substrate, polyethylene or;
• decorative cladding.

Device steps:

Preparation:

• The first thing to do is to prepare the surface and align the base. Often in a country house use a cement-sand tie, checking the horizontal level by lighthouses. You can use common self-leveling mixtures for warm floors.
• After that, we carry out work on waterproofing, laying the strips of dense polyethylene or aluminum foil.
• Fix with self-reserves around the perimeter of rooms for 2 cm above the screed damper tape, which will facilitate the load with linear deformation.
• On the water dispenser put the layer and. To do this, use polystyrene foam plates, plug. The thickness of the thermal insulator depends on the power of the heating system. It is better to use a special material for the arrangement of warm floors.
• To the top of the heat insulator put the reinforcement grid fixing the pipes with the coolant, and the reinforcing concrete screed.

Installation of the heating circuit circuit in the floor

Pipes are attached to the mounting grid by plastic clamps according to the selected scheme. The ideal distance between the fasteners is 0.3 - 0.4 m.

Collector mounting and connecting heating contours:

• The collector is mounted in a special niche above the floor in the center of the room on the wall. Typical sizes of collector cabinets - 0.6 x 0.4 x 0.12 m.
• We get into a niche feeding pipe from the boiler and the return hose. We put shut-off valves. Connect the collector and drown it. You can carry out the installation of the splitter, for which at one end we screw the drain valve, and on the other - the air molding. So you can disable not the necessary rooms from heating.
• At the place of exit from the screed, they protect them with special corners or corrugated tube. Cut the pipe, we dress the collapsible fitting and connect with a collector with a precipitant nut.

Balancing collector

Water floor contours often have different length. Therefore, the coolant must be selected with individual pressure. To do this, remove the protective caps on the collector and carry out the operating pressure adjustment.

Testing a warm floor

Before pouring, check the system for tightness. This can be done using a compressor and compressed air.

If everything works properly - proceed to the fill of the concrete screed. For this, the water floor should remain under pressure.

Pouring concrete tie.

On top of the system, we laid concrete, cement - sand tie or blend of bulk sex, and align in beacons with a long rule. Minimum screed thickness 5 cm.

When the mixture hardens, before lining, check its tightness again.

With the arrival of cold weather, many are thinking about the modernization of their heating system. And installation of water warm floor - one of frequent solutions Such users. After all, this design allows you to significantly save on heating, while the flow rate is sharply reduced, and the elements that provide heating and warm air, do not occupy places in the room, because hidden under the floor. We'll figure it out what are the warm floors and how to mount them in a private house with their own hands.

The principle of operation of a warm floor in the house

Heating and warm air in a cottage or private house are provided with warm floors - this is a completely new system, eliminating such actions as installation and operation of convectors with radiators, as well as a large connection of their nodes and elements. Instead, a heating contour from a pipe and a collector or several such sets is used built into the floor, if the length and width of the room is greater than one collector and the contour can cope.

All this is set, as a rule, on concrete coatingBut you can install on the wooden (though, the flow will be more). Mates are installed for warm water floors, thanks to which consumption is significantly reduced. But the most important thing is that all this can be done in the cottage or privately house do it yourself. The main thing is to know the principle of operation of this technology and comply with the rules of installation.

So, the heat-mall circuit in a private house is pipes with heat carrier, providing heating and warm air, as well as a collector, a pump and a thermostatic mixer that make up mixing nodes. All this equipment is installed with compounds to the floor, and the cement screed for warm water floors is poured on top.

When these works are completed, you can turn on the heating system and thus start warm air in the cottage. As you can see, do it yourself it is not more difficult than installing the bath, if you know the principle of work. In addition, the cost consumption will then be less.

Warm floor in a private house or cottage: advantages and disadvantages

Before you understand whether to choose such a scheme to provide warm air in a private house, and even more so do heating with your own hands, you need to weigh all the disadvantages and advantages of this technology.

The advantages of such a design are as follows:

1. The cost of heating in the house is reduced at least by 30%, and the air remains the same warm.
2. Due to the uniform circulation, the air in the cottage becomes comfortable. After all, heating applies not only to furniture near the battery, but on the entire area in the cottage.
3. Technology that provides heating with a pipe mounted to the floor is safe because there is no direct contact with hot tubeAnd the pressure in it is not so high so that the gap led to a serious accident of the entire design, as in the case of radiators, the connection is less reliable.
4. Improvement external view - Inside the cottage will now be more cozy, because there will be a large white pipe through the whole and radiators occupying a place. Instead, under the floor of each room there will be a heating circuit that covers the entire area, and in some places there are small cabinets, hiding collector with details. There it will be possible to put furniture and increase the free space.
5. The warm floor can be installed under laminate, and under the tile, linoleum and other coatings.
6. The cost of installing the equipment in the cottage is rather low, especially if you work your hands.

But there are also disadvantages of such a principle of heating of air as a technology of warm floors:

1. To install the equipment, you need to spend a lot of time, especially if you do everything with your own hands;
2. If the equipment breaks, it leads to a serious consumption for repairs, because it will have to dismantle the entire floor, to endure furniture, and at this time the heating will stop, and in the whole house the air will be cold;
3. Some large rooms will need an additional source that provides heating, since heating technology is not designed for high heating power. In order for the air to be warm, you will have to install cectors with radiators.

For this minuses that this equipment has, end.

Installation schemes for installing warm water floors

To install equipment for heating air to the dwelling with your own hands (pipes, a collector, a pump to adjust the pressure), you need to know the schemes, how to install the heating circuit under the floor, taking into account how the furniture is installed, which is the length of the room and other characteristics.

Pipe installation schemes with their own hands as follows:

• Snail;
• Snake;
• Grid;
• Combination in different waysSo that the outline is located on all surfaces.

Calculation of the warm floor and the number of necessary materials

Calculation of warm water floors - important detail Building houses with their own hands. But it is better not to do this stage independently, but with the help of professionals. They calculate what length should be at the pipe, the view that the heating circuit must have, advise you to choose the best way Installation (grid, snake, etc.), consider which costs of funds for repairs. But you can calculate everything with your own hands according to famous schemes.

So, first draw diagrams for which the grid of pipes, contours, as well as a collector for each room will be mounted.

At the same time take into account furniture, windows and other elements of the rooms. Then calculated where the pump, regulating pressure, and other required equipment, according to the scheme. After that, they choose a coating for warm water floor, calculated what should be its thickness, etc., as soon as the preparatory work on paper is made, you can move directly to the installation.

Features of assembly collector

The collector and auxiliary equipment is installed in a special cabinet for a collector. This is not furniture, but a special niche with dimensions of 500x500 (length and width) on average. The thickness of it is small - the main thing is to fit all the equipment, and it was convenient to adjust it.

Once the cabinet is installed, install the feed and return pipe for hot and cold water respectively. Collector for hot water It is connected to the feed pipe, and the collector, connecting the final portions of the pipes - with the return.

Then install the shut-off crane where the pipes with the collector are connected so that the system can be repaired. On the other side of the collector, you must not forget to establish a drain crane. If the collector itself is difficult to install, you can buy ready-made, in which all the necessary equipment will be installed, and it does not have to adjust.

Surface preparation

Before installing mats for warm water floors, which should have due thickness to conserve heat, as well as the heating circuit itself, the length of which allows you to overlap the entire surface of the room, proceed to the preparation of the surface. Need to remove garbage, close the places where it stands reinforced grid Or other interfering details, remove furniture furniture. If the floor thickness is different, that is, it is a curve, adjust it before installing a warm circuit.

The principle of preparation is this: first the waterproofing layer, the length and thickness of which is known from the size of the room (from dense polyethylene), on the edges of the self-drawing, they are attached to the damper tape, after which the heat insulation is a heat insulation - insulation for warm water floors. The more its thickness, the better, because it reduces heat consumption. On top of a steering reinforcement grid.

How to lay pipes

Heating contour from the pipe, the length of which should allow you to warm up the entire room, laid into a concrete tie, using either mounting mesh or mats or a black wooden groove. The thickness of the screed must be sufficient. The perfect thickness is 3-5 cm above the surface of the plates. If the screed is done under the tile, not laminate or linoleum, the thickness must be greater.

Scheme connecting heating contours

As a rule, any heating circuit of a warm floor is connected to the boiler. It creates due power and pressure. But its power should exceed 15-20% the power of the warm floors themselves. In this case, between it and the collector must be installed expansion tank and other security elements. They will not affect consumption. In addition, in a private house, this is the usual element of any heating scheme.

Then the pipe is connected to the collector installed in the closet away from the furniture. From the collector, the pipe goes to the warm floors itself. It is placed all over the entire area of \u200b\u200bthe room - this is the heating contour. You can not stack under the plots with bulky furniture if it always stands there. The end of the pipe is connected to the return collector. If the pressure in the pipes is weak, the pumping and mixing nodes are installed. They will also help reduce consumption.

System performance checking

Before rolling the laminate or tile above the pipes, you need to check them. This is done like this:

1. The compressor injected air into the system - the pressure should be up to 4 bar. The system is checked for depressurization. That high pressure Let me identify even the smallest gap.
2. The system is filled with water - pressure from 0.6 MPa. First, in the first half hour, the pressure should not be reduced by more than 0.06 MPa. At the second stage, the pressure is adjusted to 1 MPa, and in 2 hours it should not decrease more than 0.02 MPa.

If the test passed, you can pour the screed and retain the floor, choosing a laminate, tile or other coating as a coating, and then install furniture.

Floor laying on concrete

Traditionally, concrete floor stands as a base for warm floors. It is reliable, strong, resistant to temperature drops, smooth. Stacking are made as follows:

1. Prepare the room to work (end the furniture, tear the old floor). Align the base, cleaning it.
2. Install the waterproofing layer and damper tape.
3. Install heat and vaporizolation.
4. Steel reinforcement grid.
5. The warm floor itself is installed, check its performance.
6. Poured on top of a screed (2-3 cm above the level of pipes) and leave to dry.
7. Steel coating for the floor (laminate, tile), arrange furniture.

Warm floor under wooden floors

If a tree is the basis for the floor, this is not a problem - you can also install heating too. There is a heater between lags and pipes - it will reduce heat consumption and remove the contact between the pipe and wood.

You can also install hydro and vaporizolation. It will also be useful to reduce heat consumption. Next make a classic warm floor, at the end of which the laminate is topped with top. But that the heat return was the maximum, the insulation of the steering lags, they nail the boards between which 2 cm for pipes are made. They establish metal gutters in which there are pipes.

Due to this, the finish coating (laminate or tile) will warm up completely. From above make a screed and install the floor polymer coating (plate, porcelain stoneware), or laminate, withstanding temperature drops. Parquet and board will not fit.

This design is very successful. After all, when repairing enough to break the laminate and eliminate the problem. But the concrete floor will have to be destroyed for a long time before reaching the source of the problem. Laminate is simply removed and is also practical installed. But wooden warm floor gives a smaller thermal power - It must be considered.

Install warm floors recommended in country housesThe apartments have problems with accession to the general heating system. This rule concerns not only old houses typical projectsMany new buildings, especially in elite performance, have such a heating system. Before moving to the consideration of existing mounting schemesIt should be briefly highlighted on their advantages and disadvantages, these knowledge will help consciously decide on the feasibility of installing warm water floors.

1. Benefits. Uniform premises, increase the living area due to the absence heating radiators, Improving the interior of the room. Also heated room warm floors For efficiency, it is considered the most advantageous at present, one-time investments can pay off in the second or third year after commissioning.
2. Disadvantages. Pretty complex, from the engineering point of view of the design, require expensive additional equipment. Very serious drawback - big problems If necessary, performing repair work.

If you have accepted a positive solution and the desire to mount warm water floors did not disappear, then you can move to the consideration of possible mounting schemes.

It is the same for all the warm floors. It is necessary to start with the calculation of the power of the system, while the area of \u200b\u200bthe room is taken into account, optimal temperature, actual heat losses. The power of the warm floors should be increased for the premises located on the first and last floors, if a facade walls Do not have insulation according to the requirements of existing norms, if the finish coating is made of natural stone or ceramic plates.

Old flooring should be dismantled and, if necessary, align the base. Height difference over the entire area of \u200b\u200bthe room may not exceed five millimeters, in otherwise Significantly increases the load on the pump. In addition, the risks of education aerial traffic and difficulties to remove them.

General requirements for assembly schemes

The room should be divided into sections depending on the configuration. Draw on paper a preliminary sketch of the heating scheme. At the same time you need to perform two conditions: the number heating pipes At each site should be approximately the same, sharp turns as possible not allow. The maximum area of \u200b\u200bone section cannot exceed ≈20 m2, the length of the pipes on it is not more than 100 m. Specific values \u200b\u200bdepend on the power of the pump and technical characteristics Heating pipes.

Mounting schemes can be made of plastic (the cheapest and rather durable option), corrugated stainless (in all respects it occupy average positions) and copper (the most expensive and most reliable option) Pipes.

Next, you need to draw on paper the layout of pipes, while the conditions described above are taken into account. Distance between pipes 15-30 cm depending on necessary temperature indoors. It should be borne in mind that genital coatings cannot be heated more than + 30 ° C.

Important. During the drawing of the scheme, you should know that the pipes have a different bend radius, depending on their diameter and manufacturing material. For sex heating, the bend radius must exceed ten diameter values.

When drafting a circuit, it is necessary to perform another condition. In the room, each contour should have the same pipe length and approximately the same amount of bends. Schemes include styling pipe with a spiral method, a zigzag and a snake, it is allowed to use in one room several methods, it all depends on the features of the floor configuration. Near windows, it is recommended to increase the density of the stuffing pipes, otherwise the floor will be much colder under them.

The length of each contour increases by about two meters, they will be required for a lifting to the riser. If with plastic pipes can be slightly mistake, then the copper is too expensive to cut them into pieces, unproductive waste increase the cost of the heating system. It is possible that several sketches will have to draw, change the type and size of the contour. If the knowledge is quite small, and with the geometry at school there were problems, then professional experts recommend to take a piece of rope or thin wire and lay out the circuits of contours based on, change their location, try to make a coach of a coil or spiral.

Found optimal solutionThe circuit of the contour can be marked on the base of the felt-tip pen. Further installation of installation depends on the type of base.

Mounting scheme for concrete base

Installation of water heating by concrete base Contains several "cake layers".

It is stacked on the purified base if it has large irregularities, then it should be pre-made a screed. It is advisable to use foam concrete, it is shortened by unproductive thermal losses. The thickness of thermal insulation should be more than three centimeters, the density of thermal insulation is at least 35 kg / m3.

It is recommended to lay foam or pressed into the scheme mineral Wat Increased physical strength. In implementations there are special mats for water heating systems, they have installed clamps that make it much easier to lay pipe laying. If the room is large, then the thickness of the insulation increases.

Average on square meter The premises will need approximately five raven meters With step 20 cm. These indicators may vary with regard to the calculated power of the heating system.

Practical advice. Preferably in the scheme to provide styling with two threads. At the same time, the connection to perform in such a way that the most hot pipes of the first circuit are alternating with cooled pipes of the second. Due to such a scheme, a uniform heating of the entire floor is ensured.

After the connection of all sites, it is necessary to carry out hydrotype of the tightness of the compound. To do this, one end of the pipe is drowning, and to the second to attach the water pump. Water pressure during testing should be twice the working. Such tests will allow timely detect and eliminate leaks.

According to the contour of the room, a damper tape is provided, which compensates for thermal expansions of the top cement tie.. A layer of waterproofing is provided between the circuit of the pipes and the screed in the diagram. To this end, you can use cheap polyethylene film Thickness of at least 30 microns.

Top waterproofing is stacked metallic or plastic grid For reinforcement.

The thickness of the screed is 3-10 cm above the surface of the pipes. Screed is done in conventional method, You can use wet or semi-dry material. After cooling, the finish floor coating is installed.

The diagram draws all layers of warm floor with the indication of manufacturing materials and linear parameters.

Polystyrene scheme

More modern method, Concrete screed do no need. Such a scheme significantly accelerates mounting workallows you to use the system not only during new construction, but also during the execution period overhaul building. Due to minimum thickness All layers are able to reduce the loss of the room in height, minimize the load on the overlap.

The scheme provides for embedding in polystyrene plates of aluminum plates in which pipes are fixed. Plate thickness allows you to hide in them pipes with a diameter of up to 20 mm.

Systems from above covered with gypsum fiber plates. It is not recommended to use plywood or OSP, they have insufficient thermal conductivity, which will reduce the effectiveness of the heating system. Gypsum is perfectly carried out heat, and the addition of synthetic fibers makes it strong enough. On top of these plates can be putting the finish flooring.

Modular scheme on wooden base

It provides for the use of ready-made OSP plates with propylene grooves under pipes and metal plates. Plate thickness is at least 22 mm, the laying of thermal insulation is provided in the ceiling. A variety of configuration modules allows you to put them in the desired sequence according to the developed scheme. Depending on the step plastic pipe It is planned to use bands with a size of 130-280 mm. They have comfortable latches for fixing pipes. Dimensions 150 mm, 200 mm and 300 mm. After assembling pipes and their checks on the tightness of the contour is covered with dry-fiber plates.

Wooden base scheme

The diagram is drawn taking into account the use of wooden or osp of the rivers with a thickness of at least 28 mm. Reiki must fit on sex lags, the distance between them is a bit more diameter pipes. Metal profile plates applied as retainers, there are latches from above. The system is covered with gypsum fiber plates.

What errors are allowed during the circuit

For those who have extensive experience in the production of work, these mistakes seem funny, but newcomers often do not pay attention to them. In the future, large problems arise, there are some architectural designs to redo.

1. Not taken into account the height of the window and door openings, location of heating batteries under the window. Employ have standard dimensionsAnd the warm floor will always raise the finish coating. As a result, the height of the openings will decrease, they will have to redo. A decrease in height may exceed 10-15 centimeters depending on the heating scheme used. Increase the height of the openings is quite difficult, above them is the installed beam, its dismantling / installation requires practical knowledge of execution construction work. Raising the first floor should be taken into account at the design stage of the house, and for this scheme of laying should already be ready.

Lay Communications with Pipes

2. It is impossible to make a big fill of the warm floor without separation into parts. Heating screed substantial, thermal extensions have high values. Under these operating conditions, the screed will definitely give cracks, in the worst case, it is possible to swell. Cracked may be so much that they will be negative influence on the strength of the structure. In order to avoid this phenomenon, the scheme should provide a division of a large screed area into several sections with a damper tape. Optimal size One site is within 15-20 m2.
3. Inexperienced builders the next day, the field laying the screed includes heavene in the hope that this way accelerates the process of frost. This is a big mistake, in such conditions cement mix does not freeze, but dries. As a result chemical reactions Stop cement never gain strength. Professionals, on the contrary, in too warm rooms, one or twice a day are abundantly watering with water, only so you can have the expected strength of the floor.
4. Before mark on the scheme or already on the screed place the laying of pipes under the door threshold. During the installation of the box, you will know in what place to drill under the dowel to not damage the pipes.
5. Try not to use the method of laying pipes snake, the most optimal option - put them snail. It is somewhat harder, requires patience and attention, but efforts are quite acquitted by the result, the floor across the area will have the same temperature.
6. In the diagram you need to draw pipe layouts in all rooms at once, and not separately. If this is not done, then there are cases when it is impossible to put it correctly, the output from one room will interfere with the entrance to another. There will be pipes to cut into pieces and connect, and each unnecessary connection is an additional risk of leakage.

If everything is thought out, calculated and properly painted in the diagram, that is, confidence in the effect of warm water floors.

Most homeowners choose warm floors like additional device to the radiator contour. At the same time, various mounting schemes of water warm floors in a private house are used. Effective similar heating system in rooms where children live as well as for the bathroom. Schemes are selected in the individual design of the house or during the fulfillment of repair work.

Project scheme option in a private house

Installation schemes of water heat floors in a private house: Features and varieties

Installation outdoor heating It is performed using a cement screed. It is performed to protect the design from various loads. Warm pipes Need to contact not with air, but with a screed elements, transmitting heat surface.

Installation schemes of water heat floors used in a private house are planned and designed in accordance with the calculations of heat consumption and heat loss and have the following features:

• The required amount of heat is calculated based on the size wall structures and insulation methods different surfaces. The features of a certain climatic zone are also taken into account.
• Floor elements are not mounted under the entire surface outdoor coating. There are spaces for the installation of severe furniture, as well as indents from the walls.
• Premises with an area of \u200b\u200bmore than 30 square meters are divided into sectors. Each individual area is heated using a separate circuit connected to the collector.
• The distance between the pipes must be the same.
• Circulation pumps are required for such a design.
• Warm floor mounting patterns depend on the size of the room and heating methods. If the device is used as additional heating, then the loop step should be 0.2-0.3 meters, and if as the main one, the helix should be mounted in a distance of 0.1-015 m.
• Length of highways and the placement step depends on the diameter of the selected pipe.
• The height of the design is taken into account when designing window and doorways.

Without a competent project, it is almost impossible to get a high-quality heating system. Having studied this publication, you can easily calculate necessary power, diameter and pitch of pipes. Good luck!

The main circuits of mounting floors include: spiral, snake and zigzag. The choice depends on the specifics of the room, types of pipes and other features. For example, for large premises The use of a simple snake is not entirely correct, since the water in the circuit cools, the cold zones will be formed. While in spiral laying alternate the pipes and return pipes, which will ensure more uniform heating.

Helpful information!The diameter of the pipe should be no more than 20 mm. If section bigger size, then the volume of water and heating costs increase.

Warm floor design

The floor heating system is laid pipes in which heated water circulates. They are installed on concrete or wooden surfaces, and from above are honeclosed with the selected finish coating.

The pipes are moving hot water. The feed is performed using the main one. The air temperature under the floor rises, transmitting the heat of the outer surface of the flooring. At the same time, the entire room is heated.

Features of the design depending on the material of the finish coating

Montaja Nuances

The technology of water warm flooring schemes in a private house is determined by the characteristics of a particular heating circuit.

Mounting works of construction have the following distinctive features:

• The base for the equipment is selected taking into account the flooring.

1 - overlap beam; 2 - longitudinal beam; 3 - lags; 4 - mortgages under pipes; 5 - pipe; 6 - finish coating

• A damper tape is installed on the perimeter of the room. The cushioning element reduces heat loss in the field of floor joint with wall surfaces.

• On the concrete plates The system itself is mounted in the screed.

• Waterproofing, reinforcement grid and a layer of insulation are placed on the base.

• Pipes to the frame are mounted using clamps or steel wire.

For warm floor, special seamless pipes are used. The contour is mounted from a solid highway. The material for pipes must have corrosion resistance and high temperatures resistant.

Helpful information!As a frame and insulation, profile mats can be applied extrusion polystyrene foam. The cloth is then coated with a layer of waterproofing.

Features of connecting construction to heat source

In the outdoor circuit most often average temperature equals 35-40 degrees. Installation schemes of water in a private house are functioning with the help of a forced thin flow. The portion of the coolant from the reverse flow goes into the feed circuit.

Gas boilers are equipped with special automation. Solid fuel units require a more complex device. They are equipped with circulation pumps and special buffer container. It uses a more complex combustion adjustment.

The best option for a warm floor system is considered electric boilers. Special automation allows you to maintain the desired temperature without the loss of thermal power.

Helpful information!For heating of houses of a small area, a direct connection is applied to electric boiler. In cottages with a large area uses a special distribution comb.

Dignity and disadvantages of schemes

Installation schemes of water heat floors in a private house compared to others have the following advantages:

The disadvantages can be attributed a large number of time to mount the system. If leaks appear, you will have to remove most of the floor covering, including the screed.

Designing of warm floors in the apartment

Designing of water warm flooring circuits in a private house is different from the apartment project. After installation, it is impossible to make changes to the scheme of the arrangement of radiators. Installation of floors working from centralized heating, held at the construction stage by special organizations.

In the apartments, the coolant comes through the pipes on a separate riser, and not from the riser radiator heating. Water heats up in a special heat exchanger. If initially in the project there are no data on the floor heating device, then the connection of the new circuit must be coordinated in the management company.

Helpful information!After coordination of the project and obtain permission, a heat exchanger is established, as well as mounted, circulation pump and security group. With several contours, a collector node is applied.

Prices for mounting works of warm floors

Installation schemes of water warm floors made in a private house may have a different value. It will include materials, preparatory and installation works, as well as connecting and testing contours for strength. The cost of work per square meter varies from 1500 to 3000 rubles. Also, the price is affected by the species of the foundation and quality of equipment.

Helpful advice!It is recommended to purchase finished sets Equipment for outdoor heating. Many manufacturers offer free calculation of the entire system.

The lining density of the pipeline is determined by the required level of room warming. Near the walls I. entrance doors More dense styling is performed. At the same time, the distance from the highway to the wall should be more than 12 cm. The length of one contour should not be more than 100 meters. In addition, the joints of the highways are made using metal sleeves. The collector with is placed in a special distribution cabinet for which you need to choose a place in advance.

The quality of the mounting circuits depends complete heating of the room and the creation of a favorable microclimate in the house. Good luck in repair!
