I've got an A23 MFFI eurocombi which I believe is about 8 years old.
It's been pretty good up till now but has developed a fault where if you draw hot water from the tap it will sometimes not be very hot and you'll find the radiators getting hot and then the boiler will carry on after you turn the tap off I presume heating the rads (I'll check tonight) I wasn't sure what this could be / how much £ & whether it was something I could do myself or do I have to get a tradesman in?
