For a long time they could not carry gas into their home, so many authorities had to run around. But let's not talk about the bad. In September 2014, we conducted gas and bought a gas boiler from ARISTON, model BS II 24 FF. Its total cost is 24,000 rubles. Separately, I also had to buy a voltage stabilizer and water filters, as a result, 3000 rubles were still given for this.
A boiler was installed in the kitchen, this is a wall model weighing 30 kg. The dimensions of the boiler - 77X40X31.5 cm, in fact, do not take up much space. A fairly economical model that can heat a room up to 240 square meters, we have a house of 140 square meters, and in the coldest months we give no more than 2.5 thousand rubles. You can use the boiler up to -52 degrees outdoors, we never set it to maximum at winter, we maintain the temperature at 20C.
The temperature of hot water is adjustable in the range from 35C to 85C. You also need to maintain normal pressure in the boiler, if it suddenly drops, you just need to open the valve.
pros
saves our money, easy to manage, does a good job
