Choosing a heated floor for the garage: water or electric, installation stages. Heated floors in a garage How to install heated floors in a garage

Every motorist knows the problem of cold in the garage with the onset of winter. Repairing a car turns into a test of strength, and the risk of developing a fever increases significantly. The problem is solved by installing a heated floor in the garage, and whether it will be electric or water depends on the specifics of the room and the personal preferences of the owner. You can install the insulation yourself, without the help of specialists. To do this, you just need to familiarize yourself with the stages of the work and prepare the necessary materials.

It is not at all necessary to warm up the garage to “home” temperature, unless, of course, you plan to live in it. Instead of 18-20 degrees, 15 will be enough to feel comfortable. For this purpose, preference is given to water or electric flooring. They differ from each other in the installation principle, characteristics and design, but they have the same task - heating the room. If you are just planning to build a garage, then the option of floor insulation needs to be considered at the design stage.

Water

An economical option for insulating a garage is laying a water-heated floor. However, it requires installation or insertion into an existing heating circuit, and this is not always possible.

At the initial stage of laying the floor, some financial investments will be required, which will fully pay for themselves in the future due to energy savings. Installing a boiler in a detached garage, without a central heating system, is not profitable from an economic point of view, but is sometimes still used when other options are not possible.

What is a coolant water circuit? In autonomous systems, the heat source is a gas, electric or solid fuel boiler. Heated floor devices may be different, but they all work on the same principle: water heats the pipes, then heat is transferred to the screed and floor covering. The heated floor releases heat into the air and the garage space is heated.

Electric

Structurally, an electric floor is simpler than a water floor, but its operation requires a large amount of electricity. In this heating option, heating occurs due to heat release in a flexible conductor under the influence of electric current flowing through it. The conductor heats the screed adjacent to it, from which heat is released into the air.

There are two types of electric floor:

cable, the main element of which is an electrical cable. It can be single-core, double-core and self-regulating;
infrared. The heat source is a flexible or carbon rod emitter that generates waves in the infrared range.

Installing an electric heated floor will not cause any difficulties, but if the winter is very frosty, then the amount of payment for the electricity bill may be an unpleasant surprise. To reduce costs you need Special attention Pay attention to thermal insulation of the walls and ceiling of the garage. To do this, lay a layer of insulation no thinner than 60 mm.

Pros and cons of heated floors in the garage

Before deciding to install a TP in the garage, you need to evaluate all the advantages and disadvantages of such a device. Here they take into account the region of residence, weather conditions, financial capabilities and characteristics of the premises. The general advantages of water and electric heating options are as follows:

maintaining temperature at a certain level;
large heat transfer area, increasing heating efficiency;
uniform heat distribution;
the possibility of installing an automatic system, which gives the advantage of remote heating control.

The disadvantages of heated floors in the garage are:

frost will constantly appear on the outside of the garage door;
metal parts of the gate can freeze to each other;
evaporated moisture in the air will condense on cold structural elements and form icing.

It is necessary to highlight all the pros and cons of each type of heated floor. The electric option is good because:

only one socket is required for connection;
simple installation;
complete set with a small number of elements.
heating up to +28 degrees makes the operation of the room safe.

The disadvantage of electric flooring is its high cost. Electricity costs a lot, and this type of garage heating will increase costs. There is also a disadvantage of such a floor in subsequent repairs. If the insulation breaks or the wiring is damaged, you will have to disassemble the entire surface to find the location of the breakdown.

The advantages of a water floor are its low cost compared to the electric version. It is also easy to install and maintain. Such a heating system will last for decades. You can connect the water heated floor in the garage yourself. The disadvantage of a TP with a coolant is the need to connect it to a centralized circuit. If there is none, then arranging a water structure can cause difficulties.

Requirements for heated floors in a garage

Installing underfloor heating is one of the most effective methods of heating a room. Like all repair processes, installation of heated floors requires compliance with certain rules. First you need to draw up a diagram according to which the garage will be heated. With its help, you can calculate the amount of material required and the power of CO.

The requirements for installing an electric heated floor in a garage are as follows:

the distance between heating elements must be at least 4-5 cm from furniture, central heating system risers and household appliances;
to effectively heat the room, underfloor heating elements must cover at least 75% of the entire garage area;
The control unit is placed at least 50 cm from the floor.

Before installing a heated floor in the garage, you should find out whether the wiring already installed can withstand the increased load. If you have no knowledge in this area, it is better to take the advice of specialists.

There are slightly more requirements for installing a water heated floor in a garage and some of them are met in accordance with building regulations and rules.

The distance between the heating circuit and the wall must be at least 15 cm.
The temperature of the heated floor in the garage should not exceed 30 degrees.
The temperature difference in different parts of the room should be at least 10 degrees.
The maximum permissible water temperature in the circuit is up to 55 degrees.
Warm water floors are laid only on a flat base. The permissible error is 5 mm.
To prevent heat leakage, thermal insulation in the form of foil material up to 10 mm thick is laid in the lower parts of the garage.
The loops of the circuit are laid in one of the following ways: “single coil” or “spiral”. But it should be remembered that the first option is suitable for local heating of some part of the garage.
Installation of pipes is carried out according to the markings on the heat insulator. It is done using anchor brackets, which are attached in increments of 30-40 cm.
When screeding, the pressure in the pipes must be 0.3 MPa.

If these requirements are not met, the water heated floor in the garage may not work correctly, and if electric heating is installed, there will be a risk of a fire hazard.

Electric floor installation technology

Having decided to install an electric heated floor in the garage, you need to think through everything possible options saving energy. To do this, pay attention to the area of the room, existing insulation, the quality of thermal insulation of doors and windows, as well as the type of floor. The less heat leakage, the less electricity will be required for proper heating.

Tools and materials

When preparing the necessary tools and materials for installing the heating element in the garage, the first thing people pay attention to is the heating element. There are several options:

heating mat - flexible tape, completely ready for installation, with woven cores;
resistive cable - is a single- or two-core element that heats up to a certain temperature;
self-regulating heating element. Installation of such a cable is rational only if there is an air gap between the floor and the objects installed on it to remove heat;
infrared cable with film - consists of two layers of dense polyethylene, between which heating elements are laid;
infrared rod - consists of flexible emitter rods laid between two conductors with a pitch of 9-10 cm.

In addition to heating elements, you will need the following materials:

connecting wires;
mechanical or electronic thermostat;
ground cable;
damper tape;
screed materials;
fasteners.

The tools you will need are:

perforator;
chisel;
metal scissors;
Screwdriver Set;
roulette;
level;
level.

When everything you need is at hand, you can begin preparing the floor.

Preparatory work

Any garage sits on the ground, so to prevent some of the heat from escaping into the ground, the floor needs to be prepared.

Pour the first layer of screed, making it as even as possible
After the first layer has dried, a layer of thermal insulation made of penoplex or polystyrene is laid. The layer is 7-10 cm.
If a heating cable is used, a tape is mounted under it to ensure secure laying of the wire. If mats are used, then it is not necessary to glue the tape.

The heating wire is laid in a zigzag with a step of 25 cm. Crossing or bending the heating cable is unacceptable.

Installation instructions

Anyone can install a heated floor in a garage with their own hands, even without experience. Heating cable laid as described above and fixed using special clips on the mounting tape. The turns of the wire are laid parallel to each other without excessive tension. The junctions of the wires and contacts are insulated with bitumen mastic.

After the heating elements are laid, you need to install a temperature sensor. To do this, a small recess is made in the thermal insulation at a distance of about 50 cm from the wall and 30 cm from the floor, into which a corrugated pipe with a diameter of 2 cm is placed. The thermostat is placed in it. The pipe allows you to replace the sensor after pouring the screed.

Connections to underfloor heating elements are made with copper wire. The system can only be connected to the network through its own residual current switch. After connection, the system is checked for functionality. If everything works properly, fill in the final layer of screed.

Laying a water floor

A heated water floor in a garage can be laid on any existing base. Installation begins with design: calculation of thermal power and circuit length, selection of materials and control devices.

Materials and tools

On sale you can find standard water floor kits with automatic temperature control. Typically, such systems are designed to heat a room from 60 to 80 square meters.

For work you will need the following materials and tools:

metal-plastic pipe;
plasticizer;
heat-insulating mats;
three-way mixing valve;
circulation pump;
thermostat;
fittings for plastic pipes;
servomotor for mixing valve.

You will also need a standard set of tools for installing a heated floor in a garage with your own hands.

Calculations

The calculation consists of a pipe laying diagram. It is important to consider the distance between the turns and their length. If the heat exchanger in the garage will be the only source of heat, it is recommended to take steps of 10 cm. If there are other heating elements, then installation can be done in steps of 30 cm.

To calculate underfloor heating with coolant, special calculators and formulas are used. Independent calculations can be performed using averages, which are often used for installing floors in garages. The calculation includes:

cross-section of the metal-plastic pipe - 1.6 cm;
circuit length for heating a garage with an area of 60 sq. m. - 70-80 m;
circulation pump power - at least 2 l/s.

At walls and gates, pipe loops are laid in smaller increments. Closer to the middle it increases. The supply pipeline is laid closer to the outer walls.

Preparatory activities

Preparatory work before installing a water transformer includes cleaning and leveling the base surface. To do this, the floor is poured with a layer of concrete screed and left until completely dry.

A heat-insulating material no more than 3 cm thick is laid on a flat floor surface. It is secured on top with a damper tape around the perimeter. In this way, the thermal expansion of the screed is compensated.

The next layer will be laying dense polyethylene film and reinforced mesh, to which the heating pipe will be attached.

Installation stages

The installation of pipes through which the coolant will move is carried out in one of the following ways: “snail” or “snake”. Next, the following connection steps are performed.

The pipe is attached to the reinforcing mesh using plastic clamps.
A valve is installed to drain water from the system.
The operation of the system and its tightness are checked. For this, coolant is pumped under pressure 2.5 times higher than the operating parameter. If the pressure does not drop within 24 hours, then the system is sealed.
A layer of screed at least 10 centimeters thick is poured on top.
The floor is covered with film to ensure proper hardening of the screed.
After a month, you can conduct a test run of the system.

As decorative finishing For the floor in the garage, you can use porcelain tiles or paint the surface.

Safety considerations

Any construction activity increases the risk of injury. To prevent this from happening, when laying the TP you need to follow some safety rules:

It is better to install an electric heated floor using plastic rather than metal reinforcing mesh;
the electric floor is not checked without ensuring the quality of the contact insulation;
installation of a water TP eliminates contact of water with the electrical network.

If all processes are carried out correctly, the garage will become a comfortable room for doing what you love.

Unlike some representatives of fauna, cars do not hibernate with the onset of winter cold. And just like in the warm season, they require care and attention.

However, at sub-zero temperatures, especially if the thermometer treacherously drops below ten with a minus, it is necessary to stay in the garage for a long time and, even more so, to perform renovation work Not every owner of an iron horse can do it.

Trying to at least slightly raise the temperature in the room, some use electric heaters, and some even manage to install a potbelly stove. Such heating methods are ineffective and, moreover, require considerable energy costs. The problem can be solved by arranging water heated floor in the garage with your own hands.

Under the concept "warm floor" refers to a heating system that maintains a comfortable temperature by heating the lower part of the garage.

The heating source is a flooring mounted under the surface of the main covering. The most popular systems are considered electric And water floors.

However water floors have a number of advantages over electric heating systems. Such a warm floor significantly reduces the load on heating radiators, or can completely replace them.

The secret lies in the principle of operation of water floors. Under the main floor screed are placed pipes, inside which hot water circulates.

The arrangement of the pipes ensures uniform heating of everything flooring and a constant positive temperature due to the transfer of heat by hot water into the garage space.

In addition, the water floor has the following advantages:

ensures that there are no areas with high or low temperatures;
allows save money, since the temperature for uniform heat distribution in water floors is much lower than in conventional radiators;
installed both during the main construction and after its completion. The time difference does not play a big role.
equipped water floors pipes made of materials that are resistant to corrosion and ensure the absence of deposits. Thanks to these properties, it is much easier to maintain water floors during operation than other types of similar heating systems.
If a heating system of this type is installed in the garage, then you can afford to use any floor coverings. Another thing is that concrete screed and tiles would be more appropriate for a garage.

Man has not yet invented ideal devices, therefore, along with the listed advantages, water heated floors have annoying minuses:

mandatory presence of autonomous heating;
leaks occur;
you have to use antifreeze liquid or completely pump out the water if the garage is not in use for a long time. This measure is due to the fact that water in pipes freezes under the influence of low temperatures, causing pipe rupture.
it is required to provide a connection to the central water supply and sewerage system;
No floor screed defects are allowed. She must be perfect.

Despite all the disadvantages, only that such heating system eliminates uneven temperature of air layers in the room, and also provides high-quality heating of the air in the lower part of the garage, already speaks in favor of the decision to install it.

Types

The garage owner, before solving issues related to installing the heating system with his own hands, will have to cope with the main task - choosing type of water floor. There are three such types in total. At first glance, the question is not so difficult.

In fact, the choice is complicated by the need to fulfill a number of conditions that each type of system imposes:

Concrete. It accumulates heat perfectly and can cool down within two days. Any types of floor coverings are used for finishing. The main disadvantage is high price.

In addition to the price, what should stop you from choosing a concrete type of water floor is the natural materials used for the construction of the garage. This does not apply to permanent buildings, but for an economical panel house adapted for a garage, experts do not recommend choosing such a system.

Grazing. This type is suitable for buildings made of wood or other natural materials, when making a concrete screed is unacceptable. According to flooring technology, during the installation process a cushioning layer consisting of cardboard or polyethylene foam is placed between the aluminum plates and the floor.

This system is ideal for buildings with limited height or weak floor slabs. Subtype of flooring option - polystyrene system. Differs in versatility of installation. It can be laid both on concrete and on subfloors placed on wooden joists.

Wooden look most suitable for economical panel buildings and is available in modular and rack versions. The modular option involves the use of chipboard panels provided with channels for pipes. The rack option is the laying of heat-conducting plates, as well as heating circuits.

It is necessary to supplement the design with special chipboard layers, reaching a width of no less than 15 and no more than 30 cm. The interlayers are fastened using self-tapping screws located at a distance of 2 cm.

Heating water

In order to water floor came to life and began to supply heat, you will need to install a supply or storage water heater:

Supply water heaters are devices not intended for long-term storage of water. Such a heater is connected to central water supply and sewerage systems. The small size of supply water heaters allows them to be installed even in small garages. The downside is dependence on power outages.
Storage water heater It heats up only after it is completely filled with water. In order to warm up a room of 15 square meters, a hundred-liter container will do.

Distinctive feature storage boilers– independence from power outages, since after the water boils, a special mode is automatically switched on to ensure that the temperature is maintained. In this case, the lack of electricity will not be a problem, and the garage will not be left without heating.

Boilers can also be classified by fuel type:

In addition to the indicated devices intended for heating water, they may be offered for use solar boilers. However, despite their modernity and many advantages, their use in domestic spaces is not possible due to the specific climatic conditions.

How to make a heated floor in a garage - step-by-step instructions:

Placement of the pump and water heater. This is a responsible matter, so only professionals with a full range of equipment should be involved in its implementation. necessary tools and special equipment. And there will be someone to make a claim in case of any problems.
If the boiler cannot be placed in the garage itself, it is necessary to create for this purpose superstructure. Usually it is located on the side, and a hole is made in the garage wall to connect the device to the pipes. If you have a choice, place water heating element better below the garage level. The advantage of this placement is the possibility of eliminating the need for a pump, since water will flow into the system by gravity as the pressure increases during heating.
Security perfectly flat floor surface. If necessary, additional screed is performed.
Laying thermal insulation layer on the subfloor. You can use either special mats for water floors, polystyrene, or penoplex.
Sizing damper tape along the perimeter of the garage in order to compensate for the expansion of the floor covering under the influence of heat.
Covering the thermal insulation layer plastic film large thickness. This film is necessary to protect the insulation from leaks.
Installation reinforcing mesh. The side length of the finished cell is 20 cm.
Laying water pipes for fittings according to instructions.
Upon completion of pipe laying and installation, a test is performed finished system during the day.
Pouring concrete. The screed must be no less than 3 cm and no more than 15 cm above the pipes.
Hardening of concrete within a month. You'll have to be patient and do not turn on finished system before the end of the specified period.
Start of operation with gradual increase power at two-hour intervals.

Many consider a heated floor in a garage to be an expensive whim or, on the contrary, an unnecessary and unnecessary attribute. And all these statements are true. Warm floors are not a cheap pleasure. For some, this is expensive even for a residential building. And such a floor should only be laid when the garage is actually in constant use.

Some owners of iron horses spare no expense to ensure their proper heating. Keeping your car warm and dry is key to excellent appearance and technical condition. Since many parts in the design of a car are exposed to low temperatures and humidity. Also, constantly warming up the engine in winter leaves a not very good mark. Or if you spend a lot of time in such a room doing repairs and other things, heating will not interfere.

The covering in garages can be: earthen, wooden, concrete, poured and ceramic tiles. Due to the fact that the heated floor must withstand quite a considerable weight, be resistant to mechanical and chemical influences and moisture. Considering these factors, the use of concrete is ideal.

There are two types of coverage:

water;
electric.

How to make a heated floor in a garage with your own hands? Let's look further.

Let's analyze the process of filling this type and talk about its features. So, a water heated floor in a garage evenly heats the surface around the entire perimeter and is more economical in terms of electricity. But it has a rather labor-intensive installation process, since when using it there is a need to use a water pump. In addition, if there is a leak, it will be difficult to find it and ultimately it will be necessary to dismantle the floor covering, and after fixing the problem, lay a new one.

The algorithm for making a water-heated floor in a garage is as follows:

If there is old coating, it must be removed. Level the surface of the subfloor using an additional screed.
After this, thermal insulation about three centimeters thick (penoplex, polystyrene) is laid on top. Next comes a ball of insulation. Or special mats are used for installing water heated floors.
A damper tape is glued to the perimeter of the wall, which will compensate for the expansion of the screed when it heats up.
A plastic film is laid on the floor, and on top is a mesh of thin reinforcement to which the heating pipe is attached and secured with plastic clamps.
After laying the pipe, it is necessary to carry out a test run of the system for a period of 24 hours to identify installation defects, malfunctions and leaks.
After a thorough check, the surface is poured with concrete to a thickness of at least three centimeters. And they level the screed. Afterwards it must dry completely, which can take about a month in total.
Then the heating can be turned on. Just do this slowly, raising the temperature.

That's it, the floor is ready for use. Now you can safely park your car without worrying that it will subsequently break down due to constant exposure to cold. In addition, it is always pleasant to be in a warm and cozy room when, for example, a car is being repaired.

Electric floor heating

An electric heated floor differs from the option described above in that it has a longer service life and requires a minimum of devices and mechanisms for its installation. However, it also has a significant drawback - high current consumption.

The solution to this problem, that is, to save electricity, can be to insulate the entire building, but this will also cost a pretty penny.

You can make such a floor yourself using the following instructions:

Initially, the old screed is removed and a new one is installed. It should isolate the upper layers from groundwater.
Thermal insulation is laid without foil, and an infrared film (the main heating element) or a system of heat-reflecting cables is laid on top.
This is followed by the process of reliably insulating the contacts and installing the temperature sensor.
A plastic film is placed on top.
A trial run of the system is being carried out.
At the end, the entire screed is poured with concrete to a small thickness (except for the place where the car will pass), and allowed to dry completely.
Instead of a thin screed, the surface is laid out with plywood or any other flooring facing materials(excluding the area for the car, there must be a thick concrete screed that can support its weight).

It is highly not recommended to lay a heated floor under a board, since, as previously mentioned, the coating in the garage must withstand a lot of weight and be resistant to all kinds of influences. But the tree cannot boast of this. In addition, the process of laying and leveling a wooden floor is quite labor-intensive.

Heating floor system is an excellent option for creating comfortable temperature conditions. Such blocks can be both an additional source of heating and an individual one, fully heating a room and even the whole house. Currently, floor heating units are used to insulate not only residential buildings, but also other premises where a lot of time is spent.

So, for example, why not organize a heated floor in the garage, because for many men this is almost a second home. In the off-season and winter, such a system will allow you to evenly warm the room and keep the car intact. You will learn how to make a heated floor in a garage with your own hands from our article.

Garage heating options

You may be asking, why do we even need heated floors in a garage? Perhaps a person who does not have a car will think so, but vehicle owners will certainly appreciate underfloor heating systems in the place where their four-wheeled “iron friend” is located.

Thus, a warm floor in a garage, reviews of which are quite different, helps prevent freezing of the car mechanism. But every driver probably gets tired of wasting time starting the car in the cold season. If the garage is used throughout the year for car repairs or other purposes, then equipping it with a hidden heating system is an extremely necessary measure, since with the help of such an installation you can significantly save on heating the room.

The heated floor in the garage can be equipped with one of the following heating units:

Water heating system

The simplest option for underfloor heating. The heating element itself is a closed pipeline circuit through which hot water circulates. In this case, a boiler is used to heat the room, and the pipeline through which hot water will circulate (heat source) is filled with cement screed. As a rule, metal-plastic pipes are chosen as the coolant, which ensure uniform heating and eliminate heat loss. You can, of course, install copper or aluminum pipes in the garage - they are durable and have high thermal conductivity. However, the cost of a pipeline made from such materials will not be cheap.

Electric floors

Such a heating unit is also closed with a clamping structure, which ensures uniform heating of the floor surface. Classic version- a cable circuit operating from the electrical network, through which electrical energy is converted into thermal energy. There are more innovative models - film, infrared and thermomats.

It is not enough to ensure uniform heating of the garage; you need to take care of its high-quality insulation. The “weakest link” is the garage door - the largest heat-transmitting surface in this room.

To make it easier to decide which type of heating to give your preference, you need to understand their advantages and disadvantages.

Advantages and disadvantages of a water system

These installations are a fairly popular type of underfloor heating, and in order not to be unfounded, let’s consider their advantages:

the installation of such an installation will cost an order of magnitude cheaper than the installation of any other hidden heater;
the unit operates by circulating hot water through pipelines, thereby minimizing energy costs;
visual absence of a heating element;
uniform, gradual heating of the entire floor surface.

The disadvantages of such nodes include:

the likelihood of leaks and the difficulty of their localization;
the need to use a circulation pump and boiler.

It would also be fair to note that such a heating unit causes difficulties in adjusting the temperature regime.

Electric floors - operating features

The design and installation of this type is simpler than with the previous version of the heating unit. At the same time, energy consumption for floor heating increases significantly.

Advantages of electric floors:

the ability to warm up areas of different configurations and purposes;
no need to install a screed cement base;
visual absence of a heat source;
the possibility of arrangement in garage premises without the use of special equipment;
small size of the overall design of thermal equipment;
if problems occur, you can easily localize the location of the damage for further troubleshooting;
possibility of adjusting and setting the temperature.

The issue with concrete screed is relevant for cable construction, when a single- or two-core cable is laid on a prepared base and filled with a cement composition with plasticizers.

For a garage, cable underfloor heating is the most rational option with high efficiency and maximum heat transfer. The power of film IR floors and thermomats may not be enough to heat such a room.

The only drawback of the electrical system is the increase in costs - on average, payment for electricity will increase by 30-70%, depending on the frequency of switching on. And once again we remind you of the need to insulate the garage from the inside in order to avoid colossal heat loss.

Procedure for surface preparation

If you decide to make a warm garage with your own hands, you must adhere to the following recommendations:

the thermal insulation sheet is laid over the entire area of the room, but it is worth remembering that such material must be laid overlapping the wall ceilings to the height of the heating block;
It won’t be superfluous if you also lay a vapor barrier material in the garage, which will eliminate the possibility of heat loss;
each element of the thermal system is laid in an even layer, without the formation of folds or gaps;
insulation mats are mounted overlapping and secured with construction tape.

If your garage also has a basement, then you need to insulate it too. This is especially true for a garage with a cellar, where products are supposed to be stored in the winter.

Most often, basements are insulated with polystyrene foam, which has good performance characteristics, resistance to fungi and mold, and an affordable price compared to other materials with identical functionality.

Step-by-step instructions for laying heated floors

How to make a warm floor in the garage? To answer this question, we offer you step-by-step instructions:

We form a soil cushion. To do this, you need to take any soil base suitable for these purposes, place it on the surface of the garage and compact it well so that the layer thickness is at least 30 cm.
Next we lay a layer of sand and compact it in the same way. The thickness of this layer should be at least 10 cm.
We fill the rough screed, which will require reinforced mesh and cement mortar.

We wait until the screed is completely dry, and this can take about three weeks, it all depends on the weather conditions outside.
We lay a waterproofing sheet, which can be polyethylene film, on the dried screed.
Next comes the laying of thermal insulation material, which is again covered with waterproofing.

Now we need to make markings where the mounting tape will go in the future.

Laying the mounting tape at a distance of 50-100 cm, depending on the length of the cable and the need for uniform heating.

The cable laying step should not exceed 30 cm, otherwise such a system will be of little use. It is forbidden to overlap the turns and allow the heating wire to bend.

To determine the exact distance between the turns, correctly calculate the pitch

Mounting tape allows you to attach wires parallel to each other quickly and easily. With high-quality fixation, they will not move when pouring the screed and will not come into contact with each other.

The heating cable is located only on open areas of the surface - not under workbenches, not under shelves or cabinets. Exclusively in an open place, free from any furniture and large objects.

Check the distance of the cable from the walls - at least 5 cm.

The distance between the turns varies between 8-10 cm. Can be increased. But only on the condition that foil thermal insulation is used, the task of which will be to distribute heat evenly over the surface.

After the cable was laid, it was time to install the thermostat. To do this, a groove is made on the wall at a distance of 0.5 meters from the surface, into which a corrugated pipe Ø 20 mm is laid, where the temperature sensor will be placed. Subsequently, after installation is completed, the thermostat can be replaced.

Connecting the floor using a copper wire of the appropriate cross-section. Install a thermostat on the wall at a distance of 30-50 cm, connect the floor and thermostat to it, and then follow the manufacturer’s instructions. If everything went correctly, it’s time to screed the floor.
Prepare a cement mortar with the addition of plasticizers and apply it to the heating cable. The height of the screed is no more than 5 cm, otherwise the heat will not be enough to penetrate through it.

We hope our tips for organizing a garage will help make your wishes come true. If you understand that you cannot cope with this task on your own, then professional craftsmen will help you equip your garage space with an internal heating unit.

Garage buildings never lose their relevance. They are intended for parking and repairing vehicles. Warm floors in the garage provide comfortable temperature regime in the cold season for the owner and his car. This is important for maintaining health. Repairing a machine requires lying down under it for a long time.

Warm floors prevent the occurrence of corrosive damage to machine parts due to high air humidity. Thanks to them, the number of rusted parts is reduced.

The floor in the garage must have certain technological qualities:

withstand significant loads of the weight of the machine, without cracking or sagging;
not to be deformed from mechanical impact in the event of a sharp fall of tools or machine parts;
the surface should not be corroded by the harmful effects of fuels and lubricants;
participate in creating the optimal temperature in the room in order to reduce wear of machine parts,
do not absorb harmful substances, so as not to spread an unpleasant odor in the room;
look aesthetically pleasing and stylish. In decorating the garage, the owner shows individuality and his own taste to create a working mood.

When choosing heated floors, you must take into account the requirements fire safety, since various flammable materials for the care and maintenance of vehicles (paint and varnish, fuels and lubricants, diesel fuel) are stored in garages.

Moisture resistance is an important feature of garage floors. IN winter period a lot of snow is applied to the tires and the bottom of the car, which gradually thaws in the garage.

When choosing heating using a heated floor system or installing radiators in a garage, preference is given to floor heating, since car owners often come into contact with the floor when repairing them.

Which heated floor is better to choose?

Heated floors are divided into electric and water, each of them has its own advantages and disadvantages.

To create electric heating floors, a structure of special cables is installed, which is filled with screed.

Advantages of cable floor heating:

no additional communications required, electrical wiring is sufficient;
the structure does not require maintenance, it does not rust or deteriorate if all installation requirements are met;
when installing a thermostat, floor heating is regulated economically;
Simple installation of the structure allows you to do it yourself.

A significant disadvantage of using electric floor heating is the increased consumption of electrical energy. To save it, additional thermal insulation is provided in the room. For operation, the maximum load on the electrical network coming from electric floor heating is checked.

Heating with infrared film is of little use in garages. To prevent its damage, it is necessary to make a thick screed on top, which significantly increases the cost of electricity for heating the additional material.

A water heated floor in a garage is installed using metal-plastic pipes filled with water as the most economical and effective method heating The main advantages of underfloor heating with water heating are:

economical energy consumption, the boiler can also operate on fuel or gas;
the entire room is heated and the heat is distributed evenly, eliminating the need to use radiators;
a simple system for laying a water heating structure.

Water insulation of floors has certain disadvantages:

if the garage is separate, then it is necessary to create an independent communications system, install a boiler and use a water pump to pump water. If the garage is an extension to the house, then water heating can be embedded into existing wiring;
The boiler must be heated at sufficiently low temperatures to prevent the coolant from freezing in the pipes, as a result of which they can be damaged. It is problematic to look for ruptures in pipes buried in the screed;
The screed must be perfectly smooth.

Despite the disadvantages, water floors are more practical in their use and require less costs. If the water heating contract is made of metal-plastic pipes, it can last quite a long time. Car owners can independently figure out how to make a warm floor in the garage.

Installation of heated floors

The water floor heating system is a spiral-shaped structure of metal-plastic pipes recessed into the screed. If the garage is attached to the house, then the structure is connected to the central heating system. If the garage is autonomous, then it is necessary to provide a connection to the boiler.

Preparation

Initially, a scheme for connecting the floor heating structure to the house heating system is thought out, and a location for installing the distribution unit is selected. After that, it is necessary to measure the area of the garage to calculate the length of the pipes and select a water pump of suitable power.

When connecting to a centralized heating system, it is necessary to install a mixing unit to ensure mixing of high-temperature radiator heating water and low-temperature water from the collector. When using a boiler, the temperature in it is regulated.

The distribution unit, which is hidden in the distribution cabinet, is represented by a pump, a mixing unit and a manifold group. You can purchase a ready-made factory-tested distribution cabinet, connect it to the central heating system and connect the heated floor to it through a manifold group.

It is also necessary to prepare a cushion for the metal-plastic structure of the water-based floor insulation. It is necessary to carry out thermal insulation, since the soil absorbs a lot of heat. For this he does rough screed concrete, it should not have differences in height greater than 0.5 of the diameter of the tube to prevent the appearance of air pockets in it. After the screed has hardened, it is laid out with a special heat-insulating material with protrusions on the top layer.

The projections are arranged in a checkerboard pattern and pipes are laid between them. If penoplex is used as thermal insulation up to 5 cm thick, depending on the sub-zero temperature outside, then a mounting mesh is placed on top of it to secure the pipes. Damper tape is glued along the walls of the room to compensate for the expansion of the floor covering under the influence of heat.

Installation and testing of the system

During installation, pipes are laid in a spiral to heat a large area or in a snake, that is, parallel to each other. Damaged pipes require timely replacement. After connecting the pipes into a single system, the water floor must be tested. To do this, high pressure is set in the pump, and the system is not touched for 24 hours.

After one day, you need to make sure that the pressure has equalized to no less than the working pressure and that no traces of system pressure have formed on the floor, it is even. After two days of operating the system, you need to make sure that it maintains operating temperature. Next, the floors are screeded.

Screed

When screeding, the temperature of the pipes must correspond to the room temperature, and the system must be at operating pressure. Pay attention to the temperature for screeding indicated on the package and try to stick to it.

The screed layer depends on several factors:

car weight;
carrying out repair work;
thickness of the thermal insulation layer.

The thickness of the screed layer varies up to ten cm. The heated floor is used after the screed has completely hardened. The screed will dry well in three weeks. Ceramic tiles are laid on top of the concrete screed.

Further care of the heated floor

At correct installation the system works for a long time and flawlessly. Caring for a water floor heating system involves draining the water in the warm season, preventing the water from freezing in the pipes, and using a water pump to ensure constant uniform circulation of the coolant in the pipes.

A skillful owner can make a heated floor in the garage with his own hands, subject to the basic rules of their installation. Coziness and comfort in cold weather is provided to both the owner and his vehicle.
