Installation of electric floor heating with his own hands with photos

Currently, floor heating device all the electricity began to be used more often.In this case, a special application is an electrical cable, by means of which there is a floor heating.Website independent repair of apartment, prepared a good instruction on the device, selecting and installing underfloor heating own hands with photo materials.Let's get started.

device electric underfloor heating

Option underfloor heating, which uses an electric cable, in contrast to the water heating system, available as the owners of private houses and residents of urban high-rise buildings.When the device of the electric floor heating does not require any installation of pipes and their connection to the heating system, all work is laying a thin electric cable and connect it to the mains.

system of this floor is much easier to manage, since there is a lot of variety of electronic devices, which will make sure that the temperature is kept at a predetermined level.Such warm floors can be used in a variety of areas, including holiday homes, cottages, for example, by using such a system, it is possible to maintain the desired temperature in a small country house or set on timer so that by the time of departure from the garage room was warmed up, for sure the engine is started.

On your device electric floor heating is much like a heating system in which the coolant is water.laying methods also do not differ from water floor heating installation, the only difference consists only in the fact that in this case the heating element is a cable.

How to choose an electric radiant floor.Cable Types

According to the principle of the heating cables are divided into two types - self-regulating and resistive .

entire system is electric floor heating consists of power cables, which are installed to connect the system (basically they are laid in the wall), and the actual cables, with which underfloor heating is made.To reduce resistance to heating and power connection cables is made using special couplings, as shown in Figure below.

main heating element is a resistive cable conductor having high resistance, passing through which electric current is converted into thermal energy.In order to avoid electric shock to persons, heating core covered with a layer of insulation, which is superimposed on top of a metal braid.This braid is grounded and is protected by shielding of electromagnetic fields, which result from operation.All of these are covered by the outer layers of insulation.Resistive cables can be either one or two wires.

system having solid cable is the easiest one for the electric floor heating.Its installation is laying the cable on the floor space, which should be provided to connect both ends of the cable to the power supply system, that is located on the floor of the cable in a loop.This system, along with its simplicity has one significant disadvantage, as a result of electric current flow on the conductor of the cable forms an electromagnetic field.Braid smoothes a physical phenomenon, nor the result is not always satisfactory.

In a dual-core cable has also current-carrying conductor, which is located between two heating wires.Given that the electric current flows in different directions, the electromagnetic fields generated around the wires, compensate one another.When installing cables resistance should be carefully embed them in mortar, to avoid overheating, and the cable did not come with the system.

Intelligent cables avoid the pitfalls that exist in the resistive cable, as there is a heating element, the polymer matrix.In case of overheating of one section, there is a decrease in the current, which affects the heat dissipation.In this area there is a temperature decrease, while the rest of the system is operating normally.Self-regulating cables have cost several times more from conventional heating cables, but guarantee a long service life.

rules for calculating the electric floor heating

When buying a cable, you must first determine the capacity of the entire heating system, based on 1m2.Experts advise to adhere to the following selection parameters:

- bedroom - 100-150 W / m2;

- hallway, hallway, kitchen - 150 W / m2;

- toilet, bathroom - 180 W / m2;

- balcony, loggia - 200W / m2.

Using these data, you can easily determine the specific capacity of the floor heating system.When calculating the area to be excluded, which is occupied by constantly standing objects (cabinets, sofas, bath, refrigerator, etc.).All these objects interfere with the normal circulation of air, it would cause excessive power consumption, and also in these areas may overheat and output cables from damage.

should also be borne in mind that the wiring in a residential area is designed for a maximum of 2 - 4 kW, so counting the heating power is necessary to consider this point.As an option to output separately.

cable power calculation is calculated as follows.If we take for example the bedroom area of ​​5 m2, and the power must be 100 W / m2.Get 100h5 = 500 watts.In the store you need to pick up a cable having an appropriate capacity.The closest, for example, would be a cable length of 24 m and has a capacity of 550W.Now we need to calculate the step of laying the cable - 5h100 / 24 = 21 cm (S x100 / heating cable length) will help in this our online calculator for calculating power of the electric floor heating.

Installation of electric floor heating with his hands.Installation Technology

Before you mount the electric floor heating, it is necessary to determine the place where the thermostat to be installed.For this purpose, the wall must hollow hole into which the mounting box will be installed.Usually this is done at a height of 50 - 100cm.After this procedure is necessary to the installation of the box to bring the power and grounding.From the place of installation make the groove in the wall, through which will go to a place of power wires connected to the heating cable.(The picture below illustrates one embodiment of installation technology in the room, in this example, the bath).

After all this work to begin laying the cable, after making a layer of insulation (about 2 cm thick).The cable is laid on a level surface.should ensure that the cable series do not touch each other when installing the cable.The cable is laid on the pattern obtained by calculation.Laying can be performed as parallel lines or a spiral, a great difference in this.Placement is made on mounting a tape that is placed with a pitch of about 50cm.It is necessary to carry out the power cables to the thermostat, coupling must always be in the concrete screed.After the installation of the heating cable is installed a temperature sensor, it must necessarily be mounted in a plastic tube.Before the final casting floor should check the quality of the cable tester to avoid re-disassembly ties in the case of factory defect cable.

To monitor the temperature should be given the advantage of a programmable thermostat, which will allow to use the display at a time when the owners are present in the room.

Now that everything is set up in its place, you can begin to fill in the cement - sand screed.If the surface of a solid floor, the thickness of the screed layer should be more than 3 cm., And if you need to resolve the thermal insulation layer is more than 5 cm.

To connect the heating cable is possible to start when solidify ties.Screw terminals are on the rear side of the thermostat, it is necessary to connect the wire sensors, which determine the temperature of the floor, as well as the power supply wires from the heating cable and wiring that feeds the entire system.If you are not confident that you can carry out this procedure, we advise you to give this task to specialists.

Installation of electric floor heating is over.For the analysis, and the final choice of the system, see how to make the water warm floor with their hands, mount technology is a bit different.You may want to lay the floor is water.If there were any - any questions, feel free to ask in the comments.
