I bought this chimney boiler, only of the previous design, in 2002. During its operation, I invited a repairman only twice, and I cleaned it myself periodically. We have very high cold water pressure in our house, so after a couple of seasons of operation the heat exchanger died. After the replacement, I installed a water pressure reducer at the entrance to the apartment. The second time I called a repairman was in 2010, because the nipple of the expansion tank (an ordinary car nipple, from time to time) had failed. There were no more problems
In the old model, the knob for switching the winter-summer seasons began to act a little. The Master says this to everyone. This is the switch design. Contacts need to be cleaned.
