create a plan for installation of electric floor and the calculation of its power

To begin with the arrangement of the electric Underfloor heating with the development of the plan of installation. Why is it necessary? Due to the fact that all elements of the electric heating circuit, unlike the system of water Underfloor heating, heated to the same temperature, in the case of existence of obstacles for the return of their heat is overheating that could lead to failure. Such obstacles can be massive furniture, large outdoor appliances, pipes and water heating radiators, baths, toilets and sinks. On the plan of the room you will need to mark the area free from the aforementioned devices, it will be a zone of heating. By calculating the area heated, you can proceed to the calculation of the required power of the electric floor. For this specific power electric Underfloor heating, which for balconies and loggias is 200 W/m2 for bathrooms – 180 W/m2, and for all other rooms is $ 150 W/m2, multiply the area of heating. For example, the area of the kitchen is 24 m2, if you take away from her 4 m2 occupied by kitchen furniture and appliances, the area heated will be 20 m2. Multiply the obtained area value for the power density electric floor for kitchen. the result is: 20 m2 X 150 W/m2 = 3 KW. It is this power of the heating elements necessary for the furnishing of electric Underfloor heating kitchen.

prep work

We should start with preparing space for installation of thermostat and sensor. In the wall at a height of not less than 30 cm from the floor drilled the hole for the knob, and then down from holes cut grooves width and depth of about 20 mm. before Reaching the floor, the chase continues in the horizontal plane and performed the groove length of about one meter. From the floor clean the dust and debris, assess the condition of its surface and, if necessary, align it using a cement-sand screed or self-leveling floor. Completed the preparatory work for the implementation of a floor marking that separates the heating zone from areas where the installation of an insulated floor is not required. You must remember to indent the heating elements from the walls at least 5 cm, and the indentation from the pipes, radiators and other heating appliances shall not be less than 10 cm.

Hydro - and thermal insulation

In the case where there is a need to protect the floor from moisture coming from below(for example, under the room is damp or permanent damp basement), it is lined with a layer of waterproof film into the walls by an amount equal to the thickness of future floor. Thermo-insulation is needed to heat the heating elements of the electric floor, going down. As the insulating material most commonly used penofol – polyethylene foam with a reflective coating of the foil layer. If the floor below is cold room or a warm floor is planned to be installed in unheated balconies, reflective insulation must be supplemented by a layer of insulation and extruded polystyrene foam. During heating the warm floor will expand, so don't forget the edge insulation – secure damping tape around the perimeter of the floor. Completing the whole amount of works listed, you can proceed directly to the installation of electric Underfloor heating. Good luck to you! Let you will succeed!
