There were problems with the water heater. I decided to contact this service center, as I have heard many good reviews about Rembo from my friends. And indeed, less than an hour has passed since the application was submitted, as the master has already started working. As a result, it turned out to be cheap and high-quality (there has not been a single problem with the boiler for six months now). In short, if you have problems with household and heating appliances, I recommend contacting the Rembo shopping center.
