Hello! I have a Vaillant eco tec boiler 24 kw. approx. satar 15 years. in the beginning, when it heats up the additional water boiler, it shakes, the pressure gauge shakes, etc., but when it heats up the radiators, it works flawlessly and quietly. please, what is the problem?
Appreciate the help my friend thank you
