My boiler is working fine. C/H and Water switch on and off on the timer fine. Problem is that when the room termostate reaches required temp the radiators continue to get hotter.
I can also switch the c/h off from the timer, so hot water only and the readiators continue to get hotter !!
I am no expert but could it be a faulty motorised valve/ room termostate or timer. ??
House is approx 15 years old new pump fitted last year, everything else original.
Any advise would be appreciated
