The house is large, with an area of 300 square meters, water heated floors are installed on the entire first floor. Batteries naturally stand on both floors. Heats the boiler of the manufacturer Hearth 31.5. In addition to batteries and underfloor heating, the boiler also works to heat water in the house. Problems with the boiler began immediately, I really could not ignite it. Even when fully loaded with briquettes and with two heating elements, the maximum temperature that was achieved when heating the water is 40.
And at the same time I never set everything, it included only, for example, water and the floor or batteries and water. I am not a builder and far from all these matters, so I immediately realized what the problem could not be. But in the end, I realized that the whole problem was in the chimney, the builders set my pipe diameter to 110. And as it turned out, this was not enough for such a boiler, the boiler burned quite a bit and the smell of burning was bitter-acid. I expanded the chimney by 200 and the problem disappeared. True, I still had to clean the boiler from tar, which previously flowed out of the furnace.
