It applies only to those who do not have in the house of the main gas pipeline, as well as on those who do not want to work in their house in the house. The rest of the users of this resource will be not interesting.
When the construction began, knew that gas would not be for a long time ... maybe 50 years old :). Therefore, I decided to make a heat accumulator (hereinafter ta). Purpose: to join not when you need, and when there is time at this time. Get in the house of a constant temperature to the entire heating season. Save fuel, because if fuel is burned with a large amount of oxygen, you can achieve maximum efficiency.
Heating boiler 56 kW. Why so powerful? Then so that this barrel, the volume of almost 4 cube heat for the shortest possible time. Big firing in the boiler ... in -25 on the street, I throw a 6 buckets of coal in the evening and closing the boiler. And that's it. In the house on each radiator there are budget thermal heads that do not allow to raise the temperature in the house. No such that in the evening is very hot, and in the morning cool. Accordingly, the humidity is normal. The house takes as much as you need. Heated area 190 sq.m. It turns out the boiler burned, the pump turned off, and that is hot. Heating radiators with such a scheme need to be set "the more, the better", even with 50 degrees in the heating system in the house it was warm. When buying radiators and the calculation on the area, the power of radiators was multiplied by 2.
At temperatures overboard -5 degrees, load the boiler once every two days. For minus 25 once a day. The heat exchanger in that wasted parallel to the two-circuit gas boiler, so that if necessary, do not stir the boiler, but to switch the heating to propane. But in the propane of nifiga is not budget ... in -10 cylinder per day.
That cooked from stainless steel 2 mm. The heat exchanger checked pumped into it with air 3.5 kg. Cooking a simple inverter, but the Tigov burner (it can be bought at any welding direction store) in Argon. Principle TA: Transfer the temperature from the boiler to radiators, because the boiler system is the open, and the heating system in the house is closed. The reason is simple, it is very difficult in handicraft conditions to weld a vessel working under pressure and is still very expensive :) It would be necessary to make a cylinder and not from 2mm-oh stainless steel ... if anyone uses such a heating method, I will be very happy :)
