Examples of effective heating of houses electricity gazobetona

There are examples of houses from the AAC, the owners of which have their heating costs both below and slightly higher than the value which they had in the case of heating by mains gas.

I'll start with an example home to many well-known blogger: Victor Borisov, who heats his one-storey house of aerated concrete (D400 density and wall thickness 400 mm), the heat pump "air-air":

Victor built his house of 72 m2 in 2012. and in 2013. set inverter air conditioner Mitsubishi Heavy Industries, FDUM71VNX model. Powered by heating in heat pump mode to -27gr. (Hereinafter it is disabled). Selecting the side of this type of heating it was made for the reason that its SNT only 1 phase, 230 volt, of 5 kW, the gas does not. And to heat the house on solid fuel, he had no desire to.

The practice of shows here are the numbers:

If you take 6 months of cold weather in the winter month, Victor spends an average of 2 thousand. rub. The heat pump then cost him 120 thousand., Plus duct system. I mount itself.

to the main gas connection may be hundreds of thousands of rubles.

According to Victor, performance COP (Coefficient of Perfomance - energy conversion rate):

COP = 4.02 at + 7 ° C
COP = 2.53 at a temperature of -7 ° C
COP = 2.06 at a temperature of -20 ° C

Those. advantageous to use a heat pump as the heating in the average three times. More efficient than directly through the resistors electric boiler to heat water or to supply the coolant oil or ceramic heaters.

If you shut off the electricity or come anomalous frosts, which sometimes occur in the Moscow region, the owner will leave the city. Weeks is not going to last, the house is thawed.

In addition to efficient heating, this system allows you to get more ventilation and air conditioning system. Installed equipment with GSM control. It is possible to set the temperature of 10 c. during the week when you do not show up in the house, and to the output via the smartphone is already set a comfortable temperature. The same savings. Minimal noise from the system.

An article in the blog about Victor efficiency of the heat pump heating in his house here: victorborisov.livejournal.com/308325.html

The article cites other examples of heat pump heating systems, from other owners of private houses.

Second example: channel Notes samostroyschika

The author has built one-storey house is also made of autoclaved aerated concrete area of ​​130 m2 on UWB. Geographically - European part of the country. Heated by electric boiler.

Here is his account:

In the cooler months, the heating season energy costs had, on average 4.6 thousand. rub. A average: 3400 rbl. / Month., Which is about 1 thousand. rub. / month. more expensive than it was on the main gas.

Is it worth it to connect the gas, if it is heating connection costs will pay off 25 years? If you treat it like to invest, it can be ...

In the Krasnoyarsk Territory and the main gas is not and never will be. Why - the answer I have, but it's not the topic of this article.

Personally, I began to wonder whether it is necessary to establish an automatic solid fuel boiler and costing 200 thousand. rub. (And on the installation of all the key - even more expensive)?

In Eastern Siberia, the heat pump "air-air" will be up to 2-3 months of work in a year is not effective (COP = 1). A compactor TN - it is just as expensive as the gas tank.

The cost of coal and pellets is increasing every year. A neighbor down the street in our village spends far 10 thousand. rub. / month. Pellet. gas heating project from the gas tank - it is for rich people. The project is worth 500 thousand. and the high cost of heating (gas also increases in the price). Of the benefits - it's just the convenience (uploaded - and relaxed). The use of electricity for heating is not such a luxury as it was 10 years ago. Especially in the Irkutsk region, where the lowest electricity rates (below 1 rub. / KWh)

Maybe spend the money on a quality home insulation and heat as heated floors and ceramic heaters? The heat a little cold furnace (which is provided by the project). The anomalous frosts use the stove twice a day, or leave the house to maintain the temperature of 5-10 grams. and go into the city. This approach, I wrote here
