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?
Hi Matk could you explain anti cycling and whether it can be overridden and if not what can we do to stop the radiators dropping out? Thank you

Vailants are absolute pants, punctured rubber diaphragms plagued me. I got rid of it a bought a much cheaper Ideal combi which is great.
i had this fault after turning on the valve now the display screen went off
