Economical warm electric floor: calculation of the cost of the system, calculation of the power of the heating cable, cable in the screed or under the tile, thermostat.

Conditions of survival with total cost savings make you re-evaluate the comfort and convenience of living in a new way. No lyrics, full practicality and hard calculation! Choosing a system of warm floor, you will have to carefully weigh all the advantages and disadvantages, while doing the theoretical calculations and costing of expensive equipment.

Sexual issue - a contour of convenience

The device of a warm electric floor is quite an expensive exercise. According to estimates of specialists 80 percent of the total cost of the installation is for the purchase of equipment and electrical materials, and 20 percent for the installation of automation.

If you do not take into account the cost of installation works, the cost of installing the system is indicated by two costly parts. This is the cost of the heating cable or the mat and the thermostat with the sensor. In a natural way, the question arises about "marriage by calculation," which means that everything must be calculated and calculated thoroughly.

The following factors determine the comparative characteristics of the cost of the underfloor heating system:

• selection of the heating cable and its placement in a screed or in a thin mat

• Estimated capacity of the heating system per 1 sq.m.

• selection of the heating conductor of the cable: single- or double-core type

• selection of the heating control device (thermostat).

Therefore, in order to answer the question: "Which electric heated floor is better", marketing research should be aimed at studying the possibilities and the price segment of the heating cable and the temperature regulator. As a calculation element, we introduce the definition: "1 square. m of the warm floor. "

Square meter of the warm floor system

The average cost of 1 sq.m. The floor heating depends on the specificity and area of ​​the room heating. The estimated cost will depend on the factor, is the warm floor the main source of heat or will be additional.

It is known that the cost of warm floors electric price, per meter of which varies within a few tens of thousands of rubles or hryvnia, depends on the type of heating element of the vein. The system of electric warm floor film is much cheaper than with a heating cable and mat.

how much is a square meter of the system

in Russia

It is estimated that the price of the system kit in Russia is from 2 to 5 thousand rubles per 1 sq. M. Installation and laying of the heating cable will cost an average of 500 rubles. for 1 sq.m of underfloor heating.

in Ukraine

For example, for a heating area of ​​20 sq.m. single-core cable with a diameter of 7 mm with a pitch of 12.5 cm and a system of "warm floor" from the manufacturer, the installation will cost around UAH 12 thousand. The use of a two-wire cable and installation on a similar heating area will amount to 20-25 thousand UAH. When laying the heating mat heating value of the system will be 33 thousand UAH.

The cost of equipment will be:

Calculation of the floor heating system

calculation of heating cable power

It is recommended to calculate cable power using an on-line calculator. As a result of the calculation, the minimum power values ​​will be obtained.

When calculating, it must be remembered that the following characteristics affect the parameters:

  • the floor surface area, which is directly dependent on the size of the room
  • type of premises (rectangular or demarcated by partitions)
  • type of heating (main or additional heat source).

The possibility of using a heating cable

cable laying in the screed

For the underfloor heating system, an important point is the parameters of the heating cable, namely the number of heating conductors and the density of the heating cable laying. The heating cable is laid in a cement screed, which is a standard heating system. Recall that the step of laying the cable thickness of 7-8 mm is 12.5 cm per 1 sq. M.

To understand how much a warm electric floor consumes, it must be remembered that the cable in the screed warms the original concrete mass first. The time for heating increases and increases the cost of electricity.

The most budget option is the choice of a two-core heating cable, although a single-core cable is cheaper than a two-wire cable by 20 percent. In addition, the single-core cable will have to be laid on the area when creating the circuit, taking into account the return of the second end to the thermostat. Therefore, a more advantageous option is a two-wire cable.

laying of the mat under the tile

An alternative to laying the cable in the screed is the laying of a thin heating mat under the tile. By what principle to calculate and how to lay electric warm floor, using heating mats?

For a heating mat use a thin cable with a lower power per 1 sq.m. In the warm floor system, the cable is not located in the screed, but directly under the tile, reducing the heating time and saving energy consumption.

indicators of electricity consumption

There are basic and estimated indicators of electricity consumption by the system. The basic indicators of consumption are 110-160 W per 1 sq.m. Moreover, the peak consumption value is traced at the initial stage of heating and reaching a predetermined temperature regime. When the set heating temperature is reached, the system only maintains the set power consumption value.

The calculation of the consumption of energy consumed is based on the application of a formula in which the parameters of the heating area and the heating time are involved. The power consumption system can be from 1.5 kW per 1 sq.m.

But for which indicators you would not calculate the consumption of electricity, it must be remembered that the colder the weather, the greater the value of energy consumption for heating. Saving the consumption of consumed electricity is helped by the selection and installation of a suitable thermostat.

Thermoregulator

The choice of a thermostat as a heating control device is 1 sq.m. sex, it is necessary to pay a lot of attention, because this same control can be done using programming elements.

A simple thermoregulator of a mechanical type will be cheaper. But how nice to communicate with a clever device that has an adaptive function and protection! Especially if you set parameters for a long period of operation. Therefore, add to the calculation plus a few thousand UAH. or rub.

After calculating the parameters of the floor system, you can proceed with installation.
