Atem Zhytomyr-M AOGV-12 SN 12.5 kW

Very good price. It's nice that domestic manufacturers can make equipment with the same price / quality ratio. Against the backdrop of prices for imported gas boilers, we can say that the price is fantastically good. And at the same time, the quality of the boilers is at a very decent level. Yes, they do not have advanced software control, remote temperature sensors and thermostats with LCD screens. But there are good Italian safety automatics and efficient Italian gas burners. There is a system that prevents, but rather reduces soot deposits on the heat exchanger. Soot sits on a special device - a turbulator, which is made removable and which can be easily removed and cleaned during maintenance. I have not done this yet, the time has not come. But it's good that the manufacturer took care of such issues. Moreover, soot deposits can reduce the efficiency of the boiler by 15-40% in a year. The same turbulators, according to the manufacturer's idea, should improve heat transfer and increase efficiency. I won’t say whether the efficiency exactly corresponds to the declared 92%, but the gas consumption of the boiler is very moderate, according to this indicator it is not inferior to the Europeans. A useful thing is the Atem-start system for starting in extreme cold, not very good draft, and a dirty chimney. I had problems with traction in strong winds and the system really helped to start.
