a model with serious flaws
9 November 2019 
only one thing - appearance
during the first start-up, water started running out of the boiler. It turned out that the flow switch could not be seated tightly. They fixed it - but soon (six months later) the boiler stopped heating the batteries, because when the desired temperature was set, it increased several times in 2-3 seconds and the boiler immediately turned off. You set T 40 - and on the boiler it’s immediately 50-55, like it’s heated up and immediately turned off. It is impossible to heat hot water in the bath, because... the nozzle is designed in such a way that when the water is heated to 50 degrees, the boiler makes a sound like an airplane on the runway - you have to turn on the gas. Therefore, the water will no longer heat up as you want
 i recommend it don't buy
