I use the Kiturami Turbo 13 boiler for two heating seasons. The house is large, two-story with an area of 120 sq.m. It is enough to a temperature of -15, if you have to help firewood more at night. During the first winter I spent about 800 liters of joiners, in the second year it took 100 liters less, there were less frosts. Works on schedule, 20 minutes of action and 2 hours of downtime. The first year did not climb into it at all, laziness was. After the second winter, I decided to see what's inside.
I was very surprised when I did not see soot, the pipe was clean as if only from a store. But then he took off the burner and realized where the dog was buried. I installed the Resant stabilizer, I think this generally should be a mandatory application. Took on shares, the cost was 18,000. I use diesel fuel only in winter, I take it to gas stations. So my advice to you is, take a boiler for yourself, in my opinion it’s not even bad.
