How to make a heating battery with your own hands. Homemade heating radiators from pipes - manufacturing and installation

Homemade radiators, welded from pipes of large diameter, are used to heat industrial and utility rooms, which do not have special requirements for design and beauty. They have good efficiency and are cheap. What do you need to make a heating radiator with your own hands? This is exactly what we will tell you as part of our review.

Advantages and disadvantages of homemade radiators

Homemade heating radiators are full-fledged heating appliances. They will be an excellent solution for heating warehouses, production halls, corridors, basements and other non-residential premises. For their manufacture, large-diameter pipes are used, welded together by jumpers and fittings. Separate varieties are welded from bent pipes, resulting in serpentine radiators.

Serpentine radiators do not need jumpers, but it is necessary to use fittings to reinforce them.

The large area of ​​pipes used provides quite good efficiency and good heating. In order to improve heating, the pipes are made long - up to the point that their length reaches the length of the room itself. What are the advantages of homemade heating radiators?

  • Absolutely simple design- every person who knows how to work with tools and a welding machine can make a heating battery with their own hands;
  • Minimum material costs - buying inexpensive or used pipes will provide significant savings;
  • Ability to work in systems with natural and forced circulation;
  • Possibility of installing a heating element with a thermostat for autonomous operation.

It was not without certain disadvantages:

  • The need to own a welding machine - if you have never done welding, then it is better not to take on such work;
  • The need for high quality welds- Ready-made radiators must withstand high pressure;
  • Low efficiency when compared with factory batteries - here they lose a little.

The construction of home-made heating radiators is recommended in cases where the installation of the heating system is carried out on a limited budget. Also, their use will be justified if there are cheap or completely free materials (for example, if there are free pipes or the opportunity to purchase them at a bargain price).

The main disadvantage is that pipe radiators cannot be used in apartments. They do not meet safety requirements and are distinguished by their bulkiness. Therefore, they are recommended to be used only in non-residential premises.

Design features

How to make a heating radiator with your own hands from pipes? First you need to decide on the design of the radiator. Sectional varieties are the most common. They are several pipes of large diameter, interconnected by jumpers from pipes of smaller diameter. Increased structural rigidity can be achieved by welding small pieces of reinforcement.

The most popular types of radiators for self-manufacturing.

The number of pipe sections can be any. For heating large rooms, long sections are used, almost the entire length of the wall - often they consist of only two pipes. If compactness is needed, then the sections are shortened, and their number is increased to the required limits. Connecting jumpers in such radiators are installed near the ends, which ensures good passage of the coolant.

Sectional radiators have a simple design, but the use of pipes of different diameters prevents the normal passage of the coolant - high hydraulic resistance affects. Therefore, as an alternative, you need to consider radiators in the form of coils. Here are their benefits:

  • Easy to assemble - you just need to find bent elements;
  • Low resistance provides more efficient heating;
  • Stronger and more reliable design.

Coils are welded from individual elements, straight and bent, ensuring the unhindered passage of the coolant through the radiator. To give the structure increased strength, jumpers made of durable reinforcement are used.

Making a homemade radiator

Let's see how to make a heating battery with your own hands using the example of a sectional radiator. We will heat a large room, so we need a large radiator, three meters wide, consisting of four pipes. For assembly we need:

  • Four pieces of pipe three meters long (diameter 100-120 mm);
  • Sheet metal for the construction of plugs;
  • Ordinary metal water pipe for jumpers;
  • Fittings - since the radiator turns out to be large, you need to give it additional rigidity;
  • Threaded fittings.

Of the tools you will need a grinder (angle grinder) and welding machine(gas or electric).

We cut off the plugs, jumpers and pipes of the desired length. Then we cut holes for the jumpers and weld them. The last step is to weld the plugs.

If the pipe was intact, we cut four pieces of three meters from it. We process the edges of the pipes with a grinder so that the trim is smooth. Next, cut out of a piece sheet metal eight plugs - in two of them we will later insert fittings. We cut the water pipe into pieces, the length of which should be slightly larger than the diameter of the pipes used (by 5-10 mm). After that, we start welding.

Our task is to connect four large pipes with jumpers. To give additional rigidity, we add jumpers from reinforcement. We place jumpers from the pipe near the ends - here you can retreat by 90-100 mm. Next, we weld our plugs to the end parts. We cut off the excess metal on the plugs with a grinder or welding - as it is more convenient for anyone.

When carrying out welding work, it is necessary to pay Special attention the quality of the welds - the reliability and strength of the entire radiator depends on this.


1. Side connection;
2. Diagonal connection;
3. Bottom connection.

Next, proceed to the installation of threaded fittings on the side plugs. Here you need to decide how the coolant will flow - Based on this, you can choose a diagonal, side or bottom connection scheme. On the last step we carefully clean all our connections with a grinder so that the radiator acquires a normal appearance. If necessary, cover the radiator with paint - it is desirable that it be white.

When everything is ready, you can start testing the radiator - for this you need to fill it with water and inspect it for leaks. If possible, pressurized water should be supplied, for example, connect a radiator to the water supply. When the check is completed, you can proceed to install the radiator in the heating system.

Today heating systems laid using plastic pipes small diameter, using for the movement of the coolant circulation pumps. Therefore, it is necessary to ensure high-quality fasteners for the radiator so that it does not break the pipes. It is best to hang it on a few metal pins driven into the wall, or mount it on metal floor supports.

Thus, there is nothing complicated in the construction of a heating radiator with your own hands - you just need to get necessary materials and deal with their welding. When selecting materials, carefully inspect them for defects. Pipes must be intact, not thinned, with a minimum of corrosion. If the metal is too thin, then it is better not to use such a pipe - the wall thickness should be from 2.5 mm. To further protect the radiator from corrosion, it is desirable to degrease, prime and paint it.

Installing a heating radiator with your own hands is a very serious decision. You need to prepare for this so as not to get emergency consequences. IN high-rise building it is better to call specialists, otherwise you can flood yourself and your neighbors from below. In the premises of a private house, you can put home-made batteries with my own hands. Making radiators is not a very difficult task.

How to install?

to install radiator batteries heating, you need to know the wiring system. It can be two-pipe or one-pipe. At single pipe system a bypass is required. This is a jumper between the pipes for the direct and return supply of the coolant. This small appliance can be turned off in the event of a malfunction in the system without turning off the entire heating system. To install radiators, you need corners, shut-off valves, nipples and other parts. We need spurs with the same thread as on the heating pipes. Mayevsky cranes are installed on the battery to release air.

The installation of batteries must be carried out in compliance with the following rules:

  • horizontal elements of the system must have a slope towards the circulation of the coolant by 0.5 cm for each meter of pipe;
  • the distance from the bottom of the battery to the floor should be at least 6-10 cm;
  • the same distance should be maintained between the lower part of the window sill and the upper part of the radiator;
  • from the battery to the wall must be left 3-5 cm.

You need to prepare the following tools:

  • torque wrench (image No. 1), heating batteries;
  • sealant, tow, sealing tape, wrenches, gas, adjustable, pliers (image No. 2), drill or puncher.

Before hanging the battery on the wall, you must drain the water from the system. Unscrew the plugs from the new product (if any). Attach the battery to the system with the use of squeegees. Holes are pre-drilled and brackets screwed in. All joints are sealed with tow or other means.

Batteries are available in stores. different type. Can buy oil radiator. It is powered by electricity. But you can build a homemade heating radiator with your own hands.

Homemade products

It is best to make a battery out of steel. It heats up quickly, perfectly gives off its heat, overheating does not threaten it. How to make a battery? For its manufacture, you need to take the following materials and tools:

  • a pipe with a diameter of 100 mm, a pipe of 25 mm, sheet steel 3 mm thick, 2 spurs of 25 mm;
  • welding machine, grinder, measuring tape, metalwork hammer, marker for marking.

The manufacture of radiators is a fairly common business. Of such kind homemade appliances have been used for garage heating for a long time. Length homemade battery from pipes can be different. You can make it equal to or less than the window sill, you can make it the entire length of the wall. The design can be multi-tiered. Most often they make two- and three-tier ones (image No. 3). They are ideal for heating the garage, residential premises. Consider an example of manufacturing a heating device 80 cm long. Work is performed in the following order:

  1. The necessary materials are purchased.
  2. Pieces 80 cm long are cut from a pipe with a diameter of 100 mm. For trimming, you can use a welding machine or a grinder.
  3. Pieces 100 mm long are cut from a pipe 25 mm thick. For a two-tiered structure, they need 2 pieces, for a three-tiered one - 4, for a four-tiered one - 6 pieces.
  4. Circles with the diameter of the main pipe are cut out of sheet steel.
  5. At a distance of 50 mm from the edges of the large pipe, holes of 25 mm in diameter are cut.
  6. The ends of the pipe are welded with circles cut from sheet steel.
  7. Thick pipes are welded in short thin sections.
  8. Spurs are welded on the upper and lower tiers.

A radiator for heating a garage or a room is ready. It remains to check its tightness. To check, you need to drown out the lower drive and pour water into the battery through the upper one. If there are no smudges on the welds, the work carried out can be considered of high quality. If smudges are found, it is necessary to mark their places with chalk or a marker, drain the water and boil the seam again. Install the battery without smudges in its place. There is no need to install a Mayevsky crane on it. But the pipe should be with a wall thickness of at least 3.5 mm. The welder must have some experience. The surface of the seams is polished with a grinder.

If necessary, increase the heat transfer. Additional screens are cut out of steel 1-2 mm thick and welded into the battery. The more screens, the warmer it will be in the garage or room.

A heating battery made from a large diameter pipe will cost much less if you buy a pipe at a scrap metal collection point. The screen for the heating radiator increases the heat transfer of the device. But you should not use various decorative plastic, wooden or metal gratings. It will be difficult to clean up the dust behind it. The amount of heat coming from heater, will drop significantly. It is necessary to take into account the following tips from professional masters:

  • the coolant should not be hotter than 130°C;
  • water in the pipes must be in accordance with the regulations;
  • it is undesirable to keep the batteries empty;
  • it is impossible to use parts of the heat main as elements of the electrical network.

Heating radiators from pipes can be made by hand.

Available in building supply stores big choice thermal equipment. Its use in some cases is not justified due to the high cost. Do-it-yourself heating radiators from pipes are used in garages, technical buildings and other office and industrial premises.

The manufacture of such batteries, as a rule, is carried out from materials that were in use. Such radiators are relatively inexpensive and quite functional. In enterprises, they are used quite widely due to their simplicity and sufficient efficiency. In closed-type heating systems, this type of device is beneficial to use for several reasons:

  1. possibility of manufacturing available materials without the use of complex and special tools;
  2. manufacturability of installation;
  3. high reliability and easy operation and maintenance.

The cost of producing such heating equipment for an enterprise or a garage owner will consist only of time and labor costs.

Features of calculating the required number of batteries for heating

Cast iron or steel radiators have the same coefficient of thermal conductivity, in fact they are varieties of iron. In the approved calculation methods, we proceed from the volumes of coolant in standard batteries. For one section of a cast-iron heating appliance, this value is one and a half liters. The heat dissipation of this element is from 150 to 170 watts.

one section cast iron radiator can be replaced with a two-meter homemade device.

By simple calculations, it was found that 1 section will correspond to an approximately two-meter home-made heating device.

Standard cast iron battery will replace cylindrical radiators with a total length of 20 meters.

The compactness of such a large structure can be achieved if several segments are connected in parallel.

Such a scheme provides for the installation of pipes horizontally, which makes it possible to use convective processes to heat the air in the room.

Radiators made of steel pipes have a rather low efficiency. The cylinder at a given volume has smallest area outer surface, which limits its heat transfer. This disadvantage is compensated in only one way: by increasing the length of the registers. Such an increase is possible only up to certain limits and is limited by the size of the room.

Advice! Increase usable area heating devices made of pipes are possible due to their parallel arrangement in several tiers.

Individual registers are combined into a battery with serial connection. The coolant passes through the first element of the system and through the bypass channel enters the second, changing direction to the opposite.

Required materials and equipment

Tubular heating radiators are produced in the overwhelming majority of cases from rolled steel that has been decommissioned. You should first assess the degree of wear, especially the wall thickness. In heating systems, pressure can reach three or more atmospheres. A wall damaged by corrosion may not withstand and burst, which will lead to leakage of the coolant. When selecting pipes, it is recommended to carry out fault detection and condition control.

Before starting work, it is worth checking the fault detection and monitoring the condition of the pipes.

The most used standard sizes of rolled steel for making registers are 100 and 120 mm. Radiators made of such materials have optimal performance and in terms of heat transfer and layout. The ends of heat engineering devices must be muffled, for which a steel sheet is used desired shape. In such heating systems, the registers are connected in serial order.

Bypass channels and fittings for connection are made from water pipes of smaller diameter. In the vast majority of cases, in order to reduce costs, these materials are also taken from scrap metal collection points. The fittings are threaded to connect them to the heating circuits using couplings and spurs.

The technological cycle begins with the preparation of materials and cutting blanks of the required length. Radiators in different schemes heating have a certain configuration, therefore, when performing this operation, a sufficiently high accuracy is required. The cut is performed in a plane perpendicular to the axis of the register.

Advice! A sheet of paper wrapped around a cylinder with the edges aligned gives a precise line for metalworking.

Welding it is better to trust a professional.

The ends of heating registers made of steel pipes of large diameter must be closed.

From sheet metal with a thickness of at least 3.5 mm, a round-shaped plug with a diameter of 105 or 125 mm, respectively, is cut out. This part must be welded to the end of the section. The seam is performed gas welding with tightness control.

At some distance from the edge, a hole for the bypass channel is cut out on the side surface of the register.

Radiators made of water pipes with a sufficiently large cross section are connected in sections.

Important! Welding work must be carried out by a highly qualified specialist who is able to ensure the quality and reliability of the seams.

The bypass channel provides a free flow of coolant from one part of the battery to another.

Radiators welded from metal pipes connected to the space heating system.

Registers of pipes of large diameter are installed in heating systems using couplings with pre-threaded threads and spurs. The inlet and outlet pipes cut into the plugs and are fixed in them with a welded seam. The assembled radiators must allow free passage of water from the supply point to the return manifold. Practice shows that it is not difficult to achieve this for sufficiently large cross sections.

Radiators welded from metal pipes are installed in their designated places and connected to the space heating system. Commissioning consists in filling the circuits with water or antifreeze and turning on the pumps. During the operation of pressure equipment, joints and seams are checked for leaks. Waste steel registers are ready to go.

Tubular radiators of industrial production

Industry also produces products of this kind. Steel tubular radiators are a heat engineering device consisting of lower and upper collectors. They are interconnected by tubes arranged vertically in two or three rows. Fins to increase the useful area on such devices are not installed. For collectors, a pipe with a diameter of 50 mm is used, for heat exchangers - 25 mm.

The heater is able to withstand a maximum pressure of up to 12 atm, and the use of pipes with a galvanized surface provides high resistance to corrosion. The thickness of the rolled steel used is 1.5 mm. There are two main layout schemes of such equipment with parallel and perpendicular arrangement of heat exchangers with respect to the collectors.

Taking into account specifications tubular batteries are recommended for use in multi-apartment residential buildings And public buildings. The design of these devices fits well into the design of rooms for various purposes and styles. Absence sharp corners makes it possible to use them in preschool, educational and medical institutions. Due to the absence of fins, they are easily cleaned of dust and dirt.

Starting building a house good host provides for expenses not only for the construction itself, but also for communications. Costs can be somewhat reduced if you make some of the heating equipment yourself, fortunately, the necessary materials can be found not only in hardware stores, but even in your own shed or in a landfill. Do-it-yourself heating radiators are a laborious, but quite affordable business, which you will learn about from our article.

Where will he stand?

Before you make a heating radiator with your own hands, think about where it will be located. Such a unit can heat a room very well, but it is quite difficult to make it an interior decoration. However, it all depends on the style, and it is possible that you can install your creation even in the living room.

However, most often such products can be seen in the premises of workshops or warehouses, that is, where a particularly spectacular design is not needed.

Important! If you are going to make several batteries, start with those that will heat the basement or corridor, see what you get, and only then decide if they are needed in other rooms.

Pros of homemade radiators

The main advantage of a homemade battery is the extremely low price, despite the fact that it is a full-fledged and very efficient unit. They are made from wide pipes. They can:

  • interconnected by jumpers;
  • made from bent pipes.

If we talk about other advantages, they are as follows:

  • you can use pipes that have already been in use;
  • the design allows such devices to work in systems with both natural and forced circulation;
  • if you put a heating element and a thermostat, the unit will be able to work autonomously.

disadvantages

Before deciding to do something, you need to learn as much as possible about the shortcomings of your future creation:

  1. To make such a thing, you need to have a welding machine and be able to work with it.
  2. It is necessary to pay special attention to the quality of the welds - they must be very reliable, because the coolant is supplied to the radiator under high pressure.
  3. Compared to radiators made industrial way, heat transfer from home-made is quite low.
  4. Homemade radiators can only be used in a private house; they cannot be placed in apartments.

Therefore, it makes sense to start such a business only if the owners of the future house are very limited in funds. A good reason to start making batteries if you can get the materials for free or at an extremely low price.

Important! Home-made batteries do not meet the safety requirements that heating devices in urban high-rise buildings must meet.

Heating register

The simplest version of a homemade battery is a heating register. The unit is made from several pipes welded together. The radiator works in the same way as the most common central heating battery:

  1. Pipes are filled with coolant.
  2. The coolant heats up the metal.
  3. From the heated metal, heat spreads throughout the room.

Heating registers can be:

  • single-pipe;
  • from multiple pipes.

According to the installation method, they are divided into two types:

  • wall;
  • floor.

Important! Similar designs were placed in the bathrooms of old houses - once towel warmers looked like this.

Bent and sectional

Heating registers that you can do yourself are of two types:

  • bent, or serpentine;
  • sectional.

Sectional radiators

From the name it follows that the unit consists of several sections. It is made of wide pipes, which are arranged in parallel. Plugs are placed at the ends. Sections are connected by thinner tubes. The coolant enters and exits through the nozzles - they should be at the edges.

To prevent the structure from falling apart at the slightest touch, the pipes are connected by jumpers. They are also needed for another purpose - to increase the area of ​​\u200b\u200bthe heated metal, and, accordingly, to increase heat transfer. First, the coolant enters the pipe at the top, then through the nozzle enters the compartment, which is at a lower level, then fills all the pipes and goes to the next section.

Important! The system must withstand a pressure of 13 atmospheres.

coils

Bent structures are somewhat simpler than sectional ones. You have seen them many times - these are the very modern heated towel rails, which are mostly installed in the bathrooms of new houses.

Serpentine radiators have a lot of advantages over sectional ones:

  • simplicity and strength of design;
  • comparative ease of installation, if it is possible to get bent pipes;
  • greater efficiency, since there is practically no hydraulic resistance.

Important! The coil is made of straight and curved pipes of the same diameter. Hot water moves through them without any obstacles. To increase the strength of the structure, put jumpers from the reinforcement.

Calculate the radiator

What size will your sectional heating radiator be? It depends, first of all, on the size of the room, as well as the length of the sections. In many industrial premises you can see pipes along the entire length of the wall - there can be only two of them. If you want the battery to take up less space, you can make it from more short pipes.

Jumpers are placed near the ends so that there is no interference with the free movement of the coolant.

Important! You should not use pipes of different diameters for sections - there will be hydraulic resistance, which will certainly affect the strength of the structure.

Making a radiator

Have you already decided on the design and weighed all the pros and cons? Fabulous! Everything is quite simple with the coil, so let's try to make a do-it-yourself sectional heating radiator for a large room. For example, you can build a battery 3 m wide in a four-pipe version.

You will need:

  • pipe 110-120 mm - 12 m (4 pieces of 3 m each);
  • sheet stainless steel for plugs;
  • metal water pipe - jumpers will be made from it;
  • building fittings;
  • threaded fittings.

Of course, such a structure cannot be assembled with bare hands - tools are needed. The set is small but serious:

  • Bulgarian;
  • angle grinder;
  • welding machine (whether it is gas or electric - it does not matter).

If everything is ready, you can start assembling the heating radiator with your own hands:

  1. Cut pieces of pipe to the desired length.
  2. Grind the ends with a grinder so that the cuts are even.
  3. cut into water pipe into pieces 5-10 mm long larger diameter sections for jumpers, also process.
  4. Cut out round plugs from sheet stainless steel - there should be 8 of them.
  5. Mark places for jumpers on wide pipes - the more there are, the stronger and more efficient the radiator will be, however, only on condition that the seams are of high quality.
  6. Cut holes.
  7. Weld jumpers.
  8. Weld a few more rebar jumpers to make the structure more reliable.
  9. When the main part of the battery is assembled, weld the plugs.
  10. Trim the plugs by cutting off excess metal.

Fitting installation

Insert fittings into two end caps:

  1. Determine how coolant will flow into your battery.
  2. Select a fitting layout.

Depending on how it will move through your system hot water, you can choose one of the following schemes:

  • lateral;
  • diagonal;
  • bottom.

In the first case, the fittings cut into the top and bottom plugs on one side, in the second case, into the top one on one side, and into the bottom one on the other. With the lower type of connection, the nodes cut into two plugs of the section below.

Appearance

After all the nodes are in place, clean up your creation so that it looks decent. It is very useful to paint - this way you will kill three birds with one stone:

  • give your product a spectacular look;
  • improve the quality of heat transfer;
  • save from corrosion.

Important! It is best to use white paint.

There are many types of heaters on the heating market. But we have always been famous for craftsmen who still prefer to do everything on their own, including radiators. Given that these devices are made of pipes, they are rarely used in apartments. But in country houses, as well as garages, this device will be simply irreplaceable. If you think over its external design, it can become a designer piece of furniture.

Homemade requires caution

All modern factory-made radiators are technically complex devices.

Now you can buy those, during which two processes occur at once - heat radiation and convection.

  1. When developing any heater manufacturers take into account many factors. Used in manufacturing the latest technology, allowing to significantly increase their heat transfer, reducing the volume of the product and its temperature.
    Therefore, a home-made heater will not even be able to compare closely with a factory one in terms of:
    • work efficiency;
    • compactness;
    • design.

Advice: before proceeding with the manufacture of the author's device, you should soberly assess the feasibility of this event.


Register Options

Let's take a look at some of the most commonly used:

Sectional
  1. The design of such a device is quite simple and consists of pipes having different diameter. By appearance it looks like a ladder.
  2. Pipes are placed parallel to each other, having large diameter by closing the ends with plugs.
  3. Pipes of smaller diameter act as elements connecting the entire structure.
  4. may be present additional elements- jumpers. In some cases, their presence may be important, since in addition to giving strength to the entire battery structure, they tend to increase heat transfer.

Principle of operation:

  1. The liquid begins its journey through the pipes from above.
  2. From there, it passes down through the connector element, then, having passed along the entire length of the pipe, it flows through another branch pipe into the next section.

It should be noted that the structures will have to experience constant pressure, and therefore, before starting operation, it is necessary to check the reliability of the welds.

Coil The shape of these devices can be judged by their name. This device heating consists of elements connected to each other by welding.

The coil does not have any intermediate connections and constrictions, and when the liquid circulates, its entire surface is heated. This allows the device to give off heat better at a lower coolant pressure.

Manufacturing

To make a battery with your own hands, you need to have at least the slightest skills in handling the equipment necessary for welding and cutting metal. At the same time, the size of the heater directly depends on the required power.

Power calculation

Since a liquid is used as a coolant, make the calculation according to a special formula based on the total area of ​​\u200b\u200bthe device and the degree of thermal conductivity of the material used in the manufacture of pipes. The best and easiest way is to use an ordinary cast iron battery as an example.

If the power of the cast-iron section, as a rule, is 160 W, and it holds 1.45 liters of liquid, a radiator consisting of ten sections can be replaced with several pipes that can hold ten times the amount of water.

According to the existing standard, for every 1 m² of living space there should be 1 kW of heating device power.

Tip: Increase your average heat output if your home's insulation leaves much to be desired.

In the photo - welding parts into one design

Training

You will need:

  • 2 m of steel pipes with a thickness of at least 3.5 mm and Ø 120 mm;
  • a sheet of steel of the same thickness for plugs;
  • pipe used in plumbing systems;
  • threaded elements for connecting pipes (spurs) Ø 25 mm - 2 pcs.;
  • reinforcement for stiffening the structure;
  • for accession of the device to system - carving connections.

Ideally, all these materials can be found in your country house or garage, then you only have to spend money on electrodes and electricity. If this is not available, you can contact the scrap metal collection points, where the price is much lower than the store price.

Tip: if the device is planned to be constantly used in a residential area, it is more advisable to purchase new pipes.

The main thing is not to buy pipes more than 120 mm in diameter. This can not only increase the volume of the coolant, which, in theory, should increase heat transfer, but also increase the load on the boiler. And this is already fraught with additional costs for paying for heating.

Process

The instruction will be as follows:

  1. cut steel pipe into 3 equal parts.
  2. Make holes in each of the received parts for connecting connecting pipes.

Tip: the holes should be located 50 mm from the ends and at different ends, as well as at an angle of 180 ° relative to each other.

  1. cut out steel sheet round elements the same diameter as the main pipe, it is they who will perform the function of the plugs.
  2. Weld them to the ends.
  3. Fix the pipes intended for water supply to the holes, and connect the pipes to each other using fittings. If the battery is large, then additional jumpers should be installed. The distance between the main pipes must be 5 mm larger than the diameter of the main pipe.
  4. Check the finished radiator for leaks. To do this, the lower hole is closed, and water is supplied to the upper one, preferably under the same pressure that is maintained in the circuit. If no leaks are detected, the device is ready for operation and can be installed in the system.
  5. Depending on the type of mounting - floor or wall, legs or brackets are welded to the radiator.

Tip: if natural circulation water, the radiator is installed at a slight slope in the direction of water movement.

It does not make sense to describe the manufacturing technology of the coil, since everything is produced in a similar way. The most important thing here is not to overdo it and not to take large-diameter pipes for the manufacture of the device.

Tip: the more crossbars you plan to make, the smaller the diameter you need to use pipes.

Output

Making a heating radiator with your own hands is a painstaking task, and also requires certain skills, knowledge and equipment. It may well replace a conventional battery when you need to heat a utility room or a room in a residential building. The video in this article will provide an opportunity to find Additional information on the above topic.
