I maintain +22 degrees in the house and pay for electricity 5-6 thousand rubles / month

It is difficult to be of benefit to the reader without destroying some of the myths that have been entrenched in his head. So today I will share more than controversial at first glance figures, or rather the amounts that I pay for heating the house.

Please read the article carefully, and ask questions in the comments, I never close them.

Introductory data about our house. Area 100 sq.m., wall material - log (~ 22 cm), insulation - 100 mm mineral wool outside. The foundation is tape, converted into USHP on its own.

Heating is purely electric. At a cost of a kilowatt-hour of 4 rubles, in December we were billed only 6 thousand rubles, which is quite small, judging by the comments of my subscribers. I will explain how you manage to save.

The fact is that we have long abandoned heating with convectors or oil radiators in favor of a conventional air conditioner.

The air conditioner and its older brother - a heat pump - use electricity not for direct heating of a heating element, like radiators, but for compressing gas with non-standard physical properties. This gas is freon r410a.

When the gas is compressed by a compressor, it heats up a lot, then warm freon from the street is pumped into the room, where it is blown by fans and carries heat into the house. Then the process is repeated.

Thanks to this, at +5 degrees of heat (off-season) from 1 kW of electricity, our air conditioner produces 3.81 kW of heat. And almost the whole house heats up.

I will make a reference to physics: read about the Carnot Cycle, and you will finally understand the principle of the air conditioner. As many commentators note, this is a "reverse refrigerator" - it takes heat from the street (and everything above -270 degrees is heat) and pumps it into the house.

You have seen the energy consumption graph of the house, you know its characteristics and understand how such savings are achieved. It remains only to tell which conditioner I use.

Conventional conduits do not heat at temperatures below freezing overboard, but I invested in Cooper & Hunter, which works up to -20 (there are models up to -30). In the Volga region, the temperature drops below -20 only for a week or two, so the conductor always works.

Conder 50 sq.m. (in fact, it heats 60 "squares" for me) was not cheap - 59,000 rubles. However, instead of 21 thousand for December 2019, for December 2020, I will pay only 6. Thus, for 1 heating season, the air conditioner will beat off its cost, then - savings.

Let me remind you that I do NOT live in the Irkutsk region, where a kilowatt-hour costs less than a ruble, but in the Volga region, where the price is 4 rubles.

I leave room for your comments and questions!
