A warm electric floor allows you to create warmth and comfort in the house. Often the floors freeze in the winter so much that they do not help carpets, no slippers. Therefore, there is a need to mount device for heating. You can do it without involving specialists, because the installation procedure of the system is not very complex. In this article we will tell you how to make an electric do-it-yourself floor heating under the tile, laminate and linoleum, consider various installation options, as well as show photos and videos instructions.

Preliminary work


It is better to install an electric heat-insulated floor in warm time. It, Of course, it’s not critical, but in the warm season to repair the floor more comfortable. In addition, such may always be required. works like pouring a new floor.

  1. First of all, you need to clean the surface. For this you have to remove the floor boards.
  2. Concrete should be well washed and dried.
  3. When the surface is dry, it must be leveled, if any such a need.

Types of electric floorsTypes of Electric Floors

There are a lot of types of electric floors. There are two main varieties of such systems:

  • two-core;
  • single core.

Twin-core is best used in the nursery, bedroom and living room. They are more expensive, but, nevertheless, are considered the most environmentally friendly. Radiation from such floors is minimal.

Single-core is better to install in places where a person is not so often.

Among all types of flooring, the most popular is the Heatluxury. However it is possible pick up other options. If possible, then when choosing it is better to consult people who have already dealt with such systems.

Electric floor device

The device of an electric floor heatingDevice electric underfloor heating

Before you make an electric warm floor, you need to figure it out in his device. Installation is carried out on a heat-insulating layer, which is made of material suitable for these purposes. After mounting the floor is poured with a solution of sand and cement. After solidification solution can be put on top of any material. It could be linoleum, and board, and other coating.

The electric floor functions thanks to the cable. Heating the cable receives electrical energy, converts it into thermal and gives into space. So the floor starts heat.

Installation processInstallation process

Floor control is carried out using a thermostat. Cable, which is poured with a solution, very durable. At least well-known trusted brands it can withstand temperatures up to 100 degrees. Indeed, in the process of heat generation, the cable is also heats up.

If the cable sheath is fragile, it may happen short circuit. The floor will have to be repaired. It is more difficult and painstaking task than just installing the floor. Therefore it is necessary choose a system of trusted companies and beware of fakes.

  1. Before laying an electric underfloor heating, it is necessary determine how long a cable may be required. Wire usually fit snake. Having determined the cable length, you must choose warm floor.
  2. Work begins with making strobes in the wall. This is the place where will subsequently be placed the thermostat of the system.
  3. Next, you need to decide on the floor insulation. Exist a lot of materials that can be put under the cable. the main thing – take into account that they are not flammable and serve a long time. The best option is mineral wool. Thermal insulation layer stacked on pre-cleaned floor.
  4. Mounting tape is laid on the heat-insulating layer.
  5. An electric floor cable is attached to the mounting tape. Stacking The cable is made by a snake.
  6. Next, you need to install a temperature sensor. Sensor wire will be spaced across cable lines to transmit data. On the At the initial stage, a tube is mounted for this wire.
  7. When wires and cables are laid, indent 5-7 cm from the walls. Also, do not lay wires close to systems. heating.
  8. Now you need to bring the cable to the thermostat. If gender two-core, then one end of the cable is mounted, if single-core – then two.
  9. It is necessary to connect a thermostat to complete the main part of the work. Three cables are connected to the device, which must settle down in the tubes. One of them is already connected, this is a cable gender. Now you need to connect the temperature sensor and the cable from distribution board. How to arrange wires correctly information can be found on the diagram located on the cover temperature regulator.

Finishing work

Warm floor - finishing workWarm floor – finishing work

The floor is installed, but it remains to do a number of work. First First of all, it’s a floor screed. The surface must be filled with cement-sand a mixture. Then the floor must be left alone until the screed completely dry. Use the electric floor while concrete dries, prohibited.

It must be remembered that such a surface is very sensitive. On her Do not install heavy objects. Even if the room before there was massive furniture, the heaviest would have to be removed.

When the screed has completely hardened, you can do any other topcoat. It can be linoleum or tile. Only when finishing work is completed, you can include a warm floor.

Under the laminate

Under the laminate

Although electric underfloor heating is very popular, not every floor can be combined. And this not so much due to the poor efficiency of the heating system, but how much the specifics of its installation. So, the heating cable first stacked on a rough screed. Under the cable, reflective heat-insulating material that will not allow heat to go down. After the flooring is heated, the finish screed is poured, and on top the laminate is mounted, all with the same substrate. As a result we we get: the cable in the cable tie warms up the concrete first layer, and only after that thermal energy will flow to flooring. But note that between the final screed and the laminate is a layer of litter, which will interfere the passage of thermal energy. Do not use laminate flooring impossible, as technology requires.

There is also another technology that eliminates the need for filling the final screed. Top cable system a protective film and a sheet of chipboard or similar material are laid. But again, such materials do not differ sufficiently thermal conductivity.

Electric heating under the laminateElectric laminate heating

Therefore, this suggests the conclusion that the installation of electrical underfloor heating under the laminate is not as effective as under the tile or porcelain tiles whose thermal conductivity is at a high level. If despite all this, you decided to use electric heating under the laminate, it is important to remember that such heating will not be basic, but only optional. Why? This is explained by with strong heating, the laminate begins to release dangerous substances for human health.

Upon reaching a temperature of 27 ° C or more, into the air formaldehyde vapors are released. They have a negative effect on human body, which leads to the development of respiratory diseases organs.

If you spend most of your life indoors, then this fact important to consider. As you know, a person passes through itself up to 20 m3 of air, in the mass it is 25 kg. What if through lungs will pass in such a mass of formaldehyde vapor? It is not surprising that in the matter of choosing a laminate and its heating system should be very careful.

Features of choosing a laminate

Features of choosing a laminate

Not every type of laminate can be used in combination with warm floors. Although modern planks are equipped with beautiful by lamination. This laminate has a high level of thermal insulation, and under constant heating, the coating itself will not deteriorate. But the problem lies in the fact that such a laminate has a low level thermal conductivity.

With this in mind, a new type of laminate was developed that also withstands constant heating and has a high rate thermal conductivity. Its difference lies in a special layer of lamination. Such a laminate has a special distinguishing mark on the packaging, which allows its flooring to be heated. It can be warm up to 28 ° C without negative consequences.

Some manufacturers indicate laminate compatibility with or other heating. For example, laminate flooring is not acceptable use with electric heating and vice versa.

Another important selection criterion is the coefficient of thermal resistance (CCC). The higher this indicator, the greater lamel has a heat-insulating indicator. So, according to European standards EN bar should have a CCC of not more than 0.15 m2K / W. In this case, also take into account the CCC used the substrate. For example, if the selected laminate has a rate of 0.051 m2K / W, and the substrate is 0.049 m2K / W, then folding these values, it turns out 0.1 m2K / W, and this is within permissible norms.

What happens if the CCC exceeds the indicated norm? In such In case the heating system will overheat, and this is negative will affect the duration of operation of the heating system and whole heating cake.

The level of CCC depends on the density and thickness of the laminate. therefore The optimum thickness of the strip for a warm floor is 10 mm.

Under linoleum

Under linoleum

Installation of electric heating under linoleum also has its own features. This material requires a smooth and uniform heating. So, the heating power per 1 m2 should equal to 150 watts. This power is enough to air temperature reached 28 ° C, and the floor will be linoleum comfortable to move barefoot. Otherwise, linoleum will be subjected to intense heat loads, and this will lead to to the following:

  • due to expansion, the material will delaminate;
  • discoloration of the coating;
  • harmful substance phenol will be released into the air;
  • the material will soften, causing it to rupture.

Given this, not every type of electric heating. An infrared warm floor will be optimal.

Installation work on layingInstallation work on styling

As for the installation of electric cables under linoleum, then in First of all, an even base is made. Then also thermal insulation coating is laid, the heating system itself and thin finish screed. The system is equipped with a temperature sensor, which will control the floor heating level. For Such heating should choose high quality linoleum. At he should not have a heat-insulating layer, otherwise this will reduce heating efficiency.

On the technology of installing infrared heating on the floor, you can read in this article “How to make IR floor heating.”

Under the tile

Under the tile

As mentioned above, a warm electric floor under the tile considered the best combination option. You can use both ready-made mats and a heating cable, which stacked on the mounting plate. The only thing to consider is some details when laying tiles on floor heating. For gluing tiles should choose the appropriate glue, which adapted to high temperatures.

The advantage of electric heating under the tile still lies in that it is not necessary to fill the finish screed. It is significantly increase heating efficiency. The glue is applied to the mats, and then gently with a notched trowel spreads over the entire surface of the floor, filling all emptiness. The glue thickness in this case should be at least 5 mm

In the process of drying the glue, turn on the warm electric floor not allowed. The glue should dry in the most natural environment. If you turn on the heating, then the glue will dry out and begin to crack. A this, in turn, will damage the heating cable.
