Why underfloor heating greatly increases electricity costs

Before changing floor coverings to a warm floor, it is necessary to calculate how much electricity will be spent in this case. Usually the numbers increase. Why does such heating increase the cost of electricity?

There are two varieties of underfloor heating - film and cable. The first is used for laminate and thick linoleum. The second is under the tile. Each of the varieties has different characteristics of power, thickness and heating temperature.

A film floor consumes 150 to 400 watts per square meter, and a cable floor - about 150 watts.

How to calculate costs

To independently calculate how much a warm floor will spend energy use the formula: W = S * P * 0.4, where the first - this is the area of ​​the heated room, the second is the capacity of the system, and 0.4 is the coefficient of the useful area of ​​heating. If you take an approximate area of ​​25 square meters. meters with a heating capacity of 150 watts, the hourly energy consumption of 1.5 kW.

After this figure is multiplied by the number of hours of use per day, and this figure is multiplied by the number of days. Thus, the final figure shows the amount of kW spent per month or a certain period. For each city, the coefficient for calculating electricity is different, it is necessary to multiply kilowatts per month to get approximate financial expenses. Based on these calculations, one can understand whether it is beneficial to make a warm floor under the given conditions or not.

It is obvious that the cost of electricity in the presence of a warm floor is increased due to the fact that they are added to the main consumption of electricity for lighting and the operation of equipment.

How to cut costs

If you calculate the payment for the underfloor heating for all rooms, then an impressive amount is obtained for a month. How can I reduce them without losing the opportunity to lay additional heating:

1. Take care of home insulation - it was found that good apartment heat insulation can reduce energy consumption by half;
2. Install thermostats - special devices that are fixed at the coldest point walls allow you to automatically turn on and off floor heating when certain temperature;
3. Installation of a multi-tariff electricity meter. The essence of the work is that at night the meter calculates kilowatts at a rate reduced by half (the size depends on the region);
4. Installation of underfloor heating only on the usable area. For example, it makes no sense to additionally heat the corridor and the bathroom, because in these places the residents are the least likely. Useful area is considered the kitchen, bedroom and living room.
