How to make a warm floor from heating with your own hands in an apartment. How to make a heated floor from heating in a private house. Necessary connection conditions

Unlike the usual radiator heating, water began to come into fashion relatively recently. This system is designed for heating the floor both in a private house and in an apartment. It is used simultaneously as both a radiator and a heat accumulator. It is capable of evenly distributing all the produced thermal energy, and also save significantly on it. Many people are already thinking about how to make a heated floor.

First of all, you need to figure out where underfloor heating can be installed. Most often it is mounted in country houses, which is due to two main reasons. And the first of them is in apartments that are connected to systems central heating, installation of heated floors is usually prohibited. This is explained by the fact that there is a threat of increasing hydraulic resistance.

The second reason is if you connect to centralized system heating, then the water, having passed through all the pipes of the heated floor, will return to the common riser already almost cold.

Considering these nuances, it is best to use in apartments electric heating floor, and in country houses - on the contrary, water. In addition, experts recommend using the latter only in insulated buildings or premises.

Warm floor in the apartment

Many experts do not advise making water floors in multi-storey buildings. But still, some of them say that there is an exception to the rule.

How to make a heated floor from heating in an apartment without harming the neighbors? There is nothing simpler, but this only applies to housing on the first floor (with upper distribution) or top floor(with bottom hot water distribution). The fact is that in these apartments the water is returned and it is quite suitable for heating the floor, while the heat in other apartments does not decrease.

There is another heating scheme with warm floors, which does not infringe on the interests of other users. It can be used in a combined bathroom or in a bathroom. But in this case, there can be no talk of any temperature adjustment. It directly depends only on the water in the central heating network, and if the latter is too hot, then the floors will warm up accordingly.

Advantages

The use of floor heating in apartments and especially in private houses has many advantages compared to conventional radiator heating. The first of them, and perhaps the most important, is the most comfortable climate in the house. Uniform heating of the air in the room across the entire surface of the floor almost completely eliminates the risk of colds. The warmth emanating from it prevents your feet from getting too cold.

A warm water floor makes it possible to expand the space of the room by removing radiators from under the windows. This system is completely hidden under the decking, does not take up space, and also allows for full-wall windows.

It can significantly reduce operating costs, since a decrease in temperature of 2 or 3 degrees will not entail any physical discomfort. In addition, the “warm floor” heating system evenly warms the entire room without creating cooled or overheated zones.

The next advantage is the absence of so-called convection currents. The radiator heating system operates in this way - the air is heated, which rises and remains under the ceiling, and when it cools down at the opposite wall, it falls to the floor. This creates a constant air circulation, lifting and transporting a lot of fine dust.

It should be noted that water-heated flooring is extremely reliable and safe system from an operational point of view. Enough simple design and a well-developed technology of creation and installation allows it to serve faithfully for at least 50 years, and this without additional maintenance.

Project implementation

Warm floors, where the heating source is water, are considered low-temperature heating device. The maximum heating of the liquid in such a system is no more than 55 ⁰C. And if you consider that the water pipes are located not only under the layer concrete mortar, and finishing material, then on the floor surface there will be only 35 ⁰С. This temperature is quite enough to feel comfortable. But at higher rates, unpleasant sensations will begin to arise when the skin of your feet touches a surface that is too hot.

Heated water floors are always convenient and comfortable. Especially if you do not need to install a water heating boiler. In private houses and apartments with existing radiators, you can make heated floors from central heating. To do this, a number of conditions must be met.

In any case, the heating system must be equipped with a circulation pump. If it still doesn’t exist, then it is better to purchase and install it than to make a gravity structure with a certain slope of the floor surface. The system can be of two types: one-pipe or two-pipe. In the first case, the supply pipe is connected after circulation pump, and the reverse - in front of the pump.

In addition, it is necessary to calculate the length of the contours. For a single-pipe type, it should not exceed 30 m, and for a two-pipe type - 50 m. It happens that the contour turns out to be longer, then it is divided into several parts and laid in parallel or in different zones.

Required Items

Heating systems that provide for the connection of a heated floor to the boiler must consist of several basic elements:

● metal-polymer or polymer pipes;

● circulation pump;

● thermal insulation materials;

● heating boiler;

● fasteners, manifolds and fittings;

● control valves and shut-off ball valves.

like this heating system you can not only mount it yourself, but also make preliminary calculations. If the main source of heat is exclusively a water floor, then it is better to order the project from specialists.

Varieties

Water heating, which is installed on a plane, can be concrete or flooring. The first type involves the installation of heated floors using concrete screed, and the second - without it. Flooring must be laid on special aluminum plates, pre-coated with polystyrene padding, or on a wooden floor, as well as on pre-installed joists. But still, concrete screed is considered more common and popular.

Connection

The most simple circuit connecting a heated floor should look like this: the first collector connects the water supply pipelines, and the second, in turn, the return flow. They are connected to the pipes with the coolant itself. This option has one significant drawback- the temperature of the water coming from the boiler is simply impossible to regulate.

The maximum that can be done is to close the shut-off valves, but this does not solve the problem itself. It is known that some floor decorative coverings spoil if heated to more than 30 ⁰C. Therefore, it is still advisable to provide temperature control.

In order for the heating floor connection diagram to be complete, it is necessary to add several additional elements, such as a three-way mixer or pump-mixing unit, a circular pump, an air vent and a drain valve.

In addition, instead of shut-off valves, it is better to install thermostatic mixers. By changing the size of the wax rod, it allows bandwidth the tap can function without sudden changes.

The presence of a pumping and mixing unit in the circuit is also necessary. It adds chilled water to the supply when it needs to reduce its overall temperature so that it does not exceed permissible limits.

Worth paying Special attention for installation of a mixing pump. It must be located between the supply pipe and the supply manifold. The liquid outlet from the output manifold is connected to its third output. This allows the pump to withdraw some of the chilled water and add it to the supply.

Installation procedure

Before you begin work on installing the system, you need to know the sequence of how to make a heated floor from heating according to all existing rules.

The installation procedure consists of several main stages:

● establishment of a collection group;

● leveling the floor surface and preliminary preparation;

● laying pipelines future system heating;

● temperature regulation.

Collector group

Work on the installation of floor water heating begins with the installation of a manifold cabinet, which should be located at the same distance from the end consumers. For example, if the heated floor will be located in two rooms, then the box should be placed in the middle between them.

To ensure that the manifold cabinet does not spoil the interior of the room, it is hidden inside the wall. During preparatory activities make a special niche using a grinder or a hammer drill. Its size should be slightly larger than the dimensions of the cabinet, and it should be placed near the floor.

The auxiliary water floor system consists of a certain number of pipelines. They are joined in the manifold cabinet and extend from main system heating. The box must contain both shut-off and control valves.

After installing the manifold cabinet, the supply and return pipelines are inserted into it. The first one goes hot water from the central system, and according to the second, it returns already cooled. At the ends of these pipelines, shut-off valves are installed in the form of valves or ball valves, which right time you can turn off the water supply. The transition between them is a special compression fitting.

All the constituent elements of the manifold cabinet are connected to a rail with outlet pipes, to which the pipelines forming the circuit stretch. As you can see in the photo, the heating floor connection diagram is quite simple, so it can be done without the help of a specialist.

Preliminary floor preparation

First of all, you need to check the horizontal plane on which the heating system will be located. Warm water floors are laid only on a previously prepared and leveled surface. And this stage of work should not be neglected. The uniformity of heating directly depends on the same layer of screed over the entire surface of the floor.

After leveling, they begin laying the waterproofing layer. Then a special damper tape is glued to the walls around the perimeter of the room, which can compensate for the linear expansion of the screed or heated floor. The excess is cut off.

"Heated floor (water)" heating is installed only with the use of heat-insulating mats made from materials such as aerated concrete, Velotherm, technical cork, mineral wool or expanded polystyrene. They prevent heat loss.

Installation

At this stage, they are fixing the heating circuit pipelines. The most popular method is to lay and fasten pipes to a special masonry mesh made of metal and laid on insulation. The pipeline is fixed to it using a binding wire.

If the thermal circuit exceeds the length of 70 m, then a second one is made. The pipeline is always carried out according to this principle - from colder zones (windows and doorways) to the warmest zones.

Examination

Hydraulic tests of already laid pipes are carried out only before they begin to be poured cement-sand mortar. They are considered successful if no leaks appear in the pipeline at a water pressure of 6 atmospheres. The time it takes to completely dry concrete floor - at least 10 days. Only if all installation conditions are met water heating will be as efficient, reliable and durable as possible.

Adjustment

The temperature of water floor heating can be adjusted in two ways: manual and automatic. The first is carried out using a ball valve, and the second - by electric drives. It must be said that automatic adjustment is the most effective for water heating.

When building a new house, the question inevitably arises about what type of heating to choose. Considering all the pros and cons various types space heating, you can come to the only the right decision, What better system You simply cannot find anything better than water heated floors. In addition, it can be connected to almost any heat source that uses various energy sources. And since it’s not at all difficult to make a warm floor from heating yourself, you can also save a decent amount of money.

Use heated floors to create more comfortable conditions steel back in the days Ancient Greece. IN modern world With the development of technology, everything is much simpler. Warm, customized flooring in an apartment can be used in any climatic conditions. Depending on the drop in temperature outside the window, this is full or additional system heating.

The cheapest and most cost-effective option is considered to be a water-heated floor in the house. The coolant is water heated by a boiler, and when living in an apartment - by central heating.

Do-it-yourself water-heated floors have good and bad sides. Before installing a heated floor in a private home, you need to take them all into account.

What are the advantages of water heating:

• Such a system provides comfortable thermal conditions. Heat rises from bottom to top. This warms up the entire room. This is especially true in private houses with high ceilings.
• When the feet are warm, the decrease in ambient temperature is unnoticeable to people in the room.
• Since underfloor heating is a low-temperature heater, it does not dry out the air.
• Water at a temperature much lower than what the radiators need is used as a heater. The use of such a system for heating in a private house is well combined with condensing boilers or heat pumps.
• It is possible to disconnect part of the circuits from the system.
• Heated concrete retains its temperature for a long time and a stable thermal regime is maintained in the room. This works well when using solid fuel boilers.
• The entire installation of a water-heated floor is hidden in the floor and does not disturb the overall picture of the room.

However, there are a number of disadvantages that you should pay attention to when installing water-heated floors in a private home:

• Required high-quality execution all stages of installation before pouring the heated floor. Correcting errors or malfunctions after the work is completed is financially expensive and sometimes impossible.
• A warm water floor in an apartment can only be installed with the permission of the relevant government authorities.
• Slow and slight adjustment of the warm water floor. Using a heating boiler, you can adjust the heated floor to a small range; in an apartment with central heating, you cannot adjust it at all.
• Not all coatings can be combined with warm floors. It is not recommended to install bulky furniture or lay carpets on them.
• The thickness of the heated floor is about 10 cm. This must be taken into account when designing the room as a whole.
• Insulation interfloor ceilings increases the load on the beams.
• Installation of circulation pumps and thermostats is required.
• The installation of such floors is quite expensive.

Weighing all the pros and cons, it cannot be said that installing heated floors means increasing comfort for a small surcharge. Although many craftsmen can make water heated floors in the house with their own hands. Performing a series important rules, you can achieve positive results.

Installation process

The entire installation of a water heated floor in a private house consists of several basic processes. By doing each one correctly, craftsmen are rewarded with warm water floors in a private home that work reliably for up to 50 years.

All work consists of:

• design;
• insulation;
• pipe laying;
• finished floor screeds.

Each part has its pitfalls. You need to get to know them better.

Creating a Project

When installing a water heated floor with your own hands, you should correctly calculate the boiler power. If there is a lack of power, the water will not warm up enough, which will affect the quality of heating. Power is usually taken 15-20% more of the total power consumption.

Each water pipe is made as a single pipe. To calculate the length, you must first draw all the contours on paper. Their laying diagram and the place of attachment of the collector are indicated.

The diameter of the pipe and the pitch of laying the water heated floor depend on the environmental conditions and are calculated during the design. It makes sense to order a project from specialized organizations. If the calculations are incorrect, warm water floors in a private house will not work well.

Insulation of water heating

In order for the heat to warm the house, and not the ground or ceilings in the neighboring apartment, they use various insulation for heated floors that are laid on prepared level base. Differences in height cannot be higher than 5 mm. The system will heat incorrectly and not for long.

A hydraulic barrier must be located between the base and the insulation. It protects the floor from moisture penetration from the ground. Overlapping is performed from polyethylene film. If pieces are spread, then they are overlapped, and all seams are taped.

Insulation for water heated floors comes from various materials. Application must be justified by location, temperature environment and type of base.

The most popular insulation materials are:

• Expanded polystyrene. It is used when insulating the first floors on the ground or in a cold basement. This insulation for underfloor heating has high density. Available in various thicknesses. The more thermal insulation is needed, the thicker the slabs are used.

In the absence of slabs required thickness You can lay thinner ones in two rows, gluing them together.

• Mineral wool. It is used to create water heating in wooden houses. It retains heat very well and fills the entire space. The disadvantage is that it is hygroscopic; it must be reliably protected from moisture.

• Profile thermal insulation is the most modern insulation for a warm water floor. It has a laminated coating and grooves or bosses that help subsequent pipe laying. The only disadvantage of the heat insulator is its price.

Thermal insulation for water heated floors is available in the form of slabs. Their installation usually does not take much effort or time. All seams or joints must be taped with foil tape to prevent moisture from getting into them and reduce heat loss.

Along the perimeter of the walls, the entire heated floor pie is separated by a damper tape. It is laid along all the walls, the remains are cut off after the screed is completed. The tape serves as a temperature stress compensator.

A waterproofing layer is placed on top of the insulation to protect it from moisture or aggressive environments (concrete, cement). It is also recommended to cover the insulation with a foil layer for better reflection and distribution of heat. In practice, this only works for wooden floors. When pouring concrete, it's just a waste of money. When using profile plates, all these steps are omitted.

Pipe laying

For installation of water heating, copper, metal-plastic and polypropylene pipes with a diameter of 15-20 mm. The diameter of the pipe depends on the size of the room and the weather in the region.

Pipes with a diameter of more than 20 mm are not used. To adjust in them required pressure water is required very much powerful boilers and pumps. This is inappropriate from the point of view of energy consumption.

For installation, two schemes for laying water heating pipes are used:

• Snake diagram. This is when the pipe is laid out in a uniform snake over the entire surface of the room. With this layout, hot water is first obtained, then it gradually cools, and the cooled water is returned to the return line. Recommended for use in sanitary facilities(bath, toilet), corridors and small rooms where the length of the contour is small.
• Snail diagram. For large rooms, it is recommended to lay out the pipes in a spiral, starting from the middle. The result is an alternation of pipes different temperatures. Heat is distributed evenly. Most hot pipe placed along outer wall to compensate for external cold.

Each circuit is laid using a single pipe. All bends are made smooth. The distance between the underfloor heating pipes is 7-20 cm. The distance from the wall is 5-7 cm.

For better insulation water heated floor in a private house between the wall pipeline and the next turn, the pipe laying step should be 5-7 cm, then how to regulate the layout of the water heated floor pipes is calculated in the drawn up plan.

The pipes are secured using special guides. Reinforced mesh is also used. It is placed above the insulation, and already connected to it using wire or plastic clamps pipes are attached.

When heated and filled with water, the pipe expands slightly. When attaching them, you need to take this into account, leaving a small gap.

When using profile slabs, pipes are simply laid in grooves or between bosses. The length of the pipe is not recommended to exceed more than 100 m. 60-80 m is considered optimal. If the room is large, you need to install many heating circuits.

Collector

One of the main elements is the collector. It connects the pipe circuit to the heating. All circuits must have the same resistance. The manifold consists of two pipes to which the heating circuits are connected, connecting to the return and supply of the boiler.

The temperature of the water heated floor is within 35°C. To adjust and smoothly change the temperature, a mixer and a thermostat are connected to the collector.

The collector must be installed above the heating level to allow air to exit the system through special air drain tap. It makes sense to equip it with two shut-off valves to allow repair or replacement of parts without draining the water.

The pipes are connected to the manifold by pressing. Before pouring a warm water floor, check the tightness. The system is filled with water or air, pressure 1.5 working, and left for two days.

The pressure may decrease slightly due to slight stretching of the pipes.

Performing a screed

After checking the tightness, they begin to pour the heated floor.

Screed for heated floors comes in different types:

Concreting (wet method)

When performing, use a solution of concrete or cement with the addition of granite screenings.

Sand is not used as part of a concrete screed over a water-heated floor due to its low thermal conductivity.

To increase the service life, the heated floor is reinforced. Metal or plastic is suitable for this. reinforced mesh. There are many step-by-step instructions on the Internet on how to properly fill a heated floor. A plasticizer and polypropylene fabric are added to the screed composition. This significantly increases service life.

When screeding under a warm water floor is performed, the pipes are under pressure.

The thickness of the screed for water heated floors depends on the subsequent coating and varies between 3 cm and 7 cm. If several circuits were performed, then the water heated floor around each part is poured separately. Between them there are expansion joints made of damper tape. The poured heated floor screed dries within a month. For uniform drying and high-quality setting, it must sometimes be watered with water.

Polystyrene system

This installation system produces a water-heated floor without screed. It is used to create heating in wooden modular houses and for insulation interfloor ceilings.

The pipeline is mounted on polystyrene or wood slabs with grooves without concrete screed.

When wood is used, insulation under water-heated floors in the form of mineral wool, laid between the lags.

Having placed the pipe in the groove, it is covered from above with aluminum plates, which are attached to the plates with special locks. When assembling a heated floor under the tiles, you need to supplement the pie chipboard board, moisture-resistant plywood or GVLP. When using laminate, it is placed on an aluminum profile.

Concreting screeds for heated floors are most often used. The poured solution retains heat better; with this installation, heated floors in the house will last more than 50 years. When, due to circumstances, this is impossible, then a dry screed is used, although the heat transfer will be worse.

Stone or ceramic tiles are best for covering heated floors. It warms up easily and holds heat well. They also use laminate or linoleum for flooring. Such flooring material must have a mark indicating the possibility of their use with heated floors.

With some effort and some investment, you can insulate your home for a long time. There are many sources of information on how to properly make a heated floor. An optimistic attitude and skill are important. Warm floors will bring comfort to many generations of households living in the house.

A well-functioning heating system is the key comfortable stay in the house without regard to weather. Along with the traditional radiator technology of the device heating circuit The warm water floor system is actively used. Its installation is labor-intensive and financially expensive, but this heating option fully pays for itself in 5 years.

In order to somehow save money, many install a warm water floor in a private home on their own. Agree, the idea of ​​receiving efficient heating with minimal capital investment is very attractive, isn't it? However, its implementation requires certain knowledge and skills from the performer.

We offer for consideration detailed material for the installation of water heated floors. The article outlines the design rules, provides advice on choosing system components, and also describes the step-by-step progress of the installation, connection and startup of the water circuit.

It is recommended to include the installation of an additional heating circuit in the project even before the start of construction - this makes calculations easier.

In a finished new house or building where it has been operating for a long time radiator system, installation of a water floor is also possible, but under certain conditions.

The benefits of water heating have long been appreciated by residents of Europe and Russia: it effectively heats rooms, saves expensive energy, and creates the most comfortable environment in bedrooms, bathrooms and children's rooms

If the desire to insulate the floor arose after the construction of the house, you should determine whether the building is suitable for this. One of the main conditions is pre-made thermal insulation of the house, since heat losses above 100 W/m² will make the installation of the floor useless.

Pay attention to the height of the ceilings: the installation “pie” with pipes takes about 15 cm, or even more, from the total height of the room. After implementation of the system, the dimensions must be maintained doorways, height from 210 cm or more.

Such schemes are recognized as the least energy-consuming, most efficient and inexpensive to operate. Options with solid fuel boilers are also acceptable.

Flawless operation of the system is possible only under two conditions: professionally performed design calculations and competent installation.

Consequently, the first steps towards installing a water heated floor in a country house or in a private house are analysis of the structure, selection of materials, and drawing up a project.

Nuances of installing heated floors

The construction of a water floor is complex and simple at the same time. It is multi-component in composition, so the main thing is to observe the order in which all layers are laid.

No. 2 - deciding on insulation

The main purpose of the insulation is to separate the screed with pipes from the base so that the heat is transferred upward and does not go in vain into the ground. A thermal insulation layer is required; without it, installing a heated floor becomes meaningless.

Warm water floors are comfortable and convenient, especially if they do not require the installation of a hot water boiler. In houses with radiator heating, you can connect heated floors to the heating system - this will allow you to create water heated floors at no extra cost.

Project implementation

To install heated floors powered by a heating system, a number of conditions are required. The heating system must be equipped with a circulation pump. In its absence, it is easier to spend money and install a pump than to carry out gravitational system with a maintained slope of the floor contour. The system can be either one-pipe or two-pipe. At single pipe system The supply pipe for the heated floor is connected after the circulation pump, and the return pipe is connected before the pump.

It is also necessary to calculate the length of the contours. For two-pipe system it should be no more than 50 meters, for a single-pipe - no more than 30 meters. If the room heating circuit is larger, it is necessary to divide it into several circuits, laid in different zones or in parallel.

Floor preparation

To avoid heat loss and not to heat the floor slabs, it is necessary to prepare the surface of the subfloor before installing the heating circuit.

1. If there is already a floor covering on the floor, it must be removed, the cracks must be filled with cement mortar, and the floor surface must be leveled using cement mortar or a thin layer of clean coarse sand. The floor surface must be checked using a level to ensure there are no distortions - if the heated floor contour is laid unevenly, areas with stagnation of coolant will form, which will worsen heat transfer.
2. It is necessary to install around the perimeter of the room, as well as at the junction of the heating circuits. The tape is available in various widths, with or without an adhesive layer. The width of the tape must be selected so that it is higher than the calculated height of the concrete screed. The mounting method is chosen depending on the wall finish. TO smooth walls The tape can be glued using an adhesive layer. TO rough surfaces the damper tape is secured with dowel nails for quick installation. The tape is necessary to ensure that the screed does not collapse when heating and cooling the floor.

   

3. After this, it is necessary to lay solid thermal insulation on the floor, which will not allow heat to escape downwards. This can be extruded polystyrene in the form of plates or rolled polyethylene foam with a foil coating. The slabs are laid end-to-end, avoiding gaps and cracks. Roll materials They are also placed end to end, and the joints are sealed with metallized tape. Due to their small thickness, roll materials are rarely used, only if, due to the small height of the room, the use of thicker insulation is impossible. A layer of polyethylene film with a thickness of 200 microns is laid on top of the insulation - it is necessary in order to create Better conditions to dry the concrete screed and prevent concrete leakage.

   

4. Reinforcement is laid on the floor. This can be a reinforcing mesh with a cell of 10 cm or more, or a mesh made of 6-8 mm rods, connected at the intersections with wire. The mesh is laid on plastic guides to create a gap between the reinforcement and the base.
5. To create a warm water floor from heating, special polystyrene slabs with bosses are convenient - they are designed for laying a water circuit and do not require the installation of guides. It should be noted that when laying polystyrene with bosses, it is necessary to use metal-plastic pipes, not polyethylene, and install the fittings after laying the water circuit.

   

Laying the water circuit and pouring the screed

After preparing the floor, it is necessary to lay the water circuit from metal-plastic pipes according to a pre-planned plan. You can also use cross-linked polyethylene pipes. Usually two installation methods are used: “snake” and “snail”. Laying “snail” is more profitable - the circuit contains fewer corners, while the colder pipes of the return circuit run next to the hot direct circuit, which avoids the so-called “zebra” - sections of warm and cold floors. Water circuit pipes are usually laid in 15 cm increments to southern regions You can also use a step of 30 cm. If you need to make the floor in any area warmer, the laying step on it can be increased. The diameter of the water circuit pipes is chosen smaller than the diameter of the main pipes, otherwise the pressure in them will be insufficient.

A warm floor in a room is an excellent basis for laying any finishing coating: tiles, linoleum, laminate. A heated floor with a water circuit has one drawback - it has a significant height, about 10 cm. If the height of the room does not allow you to create a heated floor from heating with a concrete screed, you can create heated water floors using or electric ones.

Today, installation of a heating hydraulic circuit in flooring, enjoys unprecedented popularity among our compatriots. The reason for this is the extremely unsatisfactory performance of classic radiator heating with a centralized coolant supply. The hype around the “warm floor” technology forces many “craftsmen” to agree to a direct ban from the authorities, arbitrarily installing heating in an apartment along the floor, thereby disturbing the thermal balance and increasing the hydraulic resistance in the heating system (CO) of the entire house.

Legal ways to implement water heated floors in apartments apartment buildings Yes, and you can connect a heated floor system from central heating. This publication will discuss several operating schemes that will not cause hydraulic and thermal imbalance in the CO.

Secondary ring diagram

This scheme can be implemented with a single-pipe CO system in an apartment. The primary ring is the central CO; secondary – the “warm floor” circuit.

• Box in central system heating is produced only in the return line, at the outlet of the radiator.
• Installed on the circuit shut-off valves, and on the return of the “warm floor” ring there is also check valve, preventing the coolant from moving in the opposite direction.
• The apartment is equipped with water heated floors mixing unit which includes a pump and a three-way valve.

Despite its simplicity, this scheme is effective, but only if correct installation and a clear assembly sequence.

Advice: The problem is whether you can prove to utility companies that this scheme is workable and does not lead to an imbalance in the centralized CO. As a rule, specialists from regulatory services refer to the prohibition of making any design changes to the heating system. Therefore, we strongly recommend that before creating a heated floor using this technology, you consult with a lawyer and a professional heating engineer.

100% of heating engineers will say that without breaking the law, you can create heated floors in an apartment with individual heating.

Despite the ban from public utilities on making any changes to the centralized heating system, experts came up with a scheme in which, when implemented, an autonomous heating system will be created, where the tank will act as a heat generator indirect heating(buffer tank, heat accumulator), heat exchanger.

This system does not affect the design of the central CO in any way, does not change the pressure and does not increase hydrostatic resistance. The numbers indicate the following equipment:

• 1 Circulation pump
• 2 Three-way mixer
• 3 and 4 Ball valves
• 15 Heat exchanger piping group, which includes: check valve; ball valve with a mud man.

Anyone can assemble a Warm floor from heating in an apartment with their own hands according to this scheme. home handyman. For a clearer understanding of the assembly process, we recommend watching a video on the topic:

Points to remember

Warm floor or radiator: which is better for an apartment

Every day a huge number of our compatriots wonder how to make a warm floor from heating, as they are firmly convinced that this design heating an apartment is more efficient than a classic radiator. Let's consider the economic feasibility of each CO.

1. The heated floor system is more economical. This issue is especially important for the owner of autonomous heating systems and the owner of apartments with heat meters. For this design, as the main heating system, it is necessary to reduce the heat loss of the home to a level of 40-50 W/m2. But with such low heat losses, radiator CO will be no less effective.
2. There is a common belief that when heating with radiators, “it’s hot at the top and cold near the floor.” As a rule, everything depends, again, on the insulation of the home. If it complies with European standards, then the difference in air temperature under the ceiling and near the floor, even with radiators, will be minimal, 1-2°C.
3. The level of comfort increases significantly if you install a “warm floor” system in all rooms of the apartment. Indeed, it is more pleasant to walk on such a floor, but answer yourself the question: are you ready to end up with carpet, linoleum and other materials throughout your entire apartment? floor coverings in favor ceramic tiles with the best heat transfer?

And lastly: compare the costs of implementing the “water heated floor” project, including permits, a design with calculations, expensive installation and performance adjustment with high efficiency, which is a rather controversial point.

Advice: Competent calculation of a water heated floor is a complex process that requires experience and knowledge of many nuances. That is why, to carry them out, contact only professionals.
