We have a Halstead Finest Gold boiler. The central heating part of which works fine. However, recently the boiler has failed to fire when we turn on a hot water tap. However, if we turn all three hotwater taps on the system, the boiler fires up aftrer a few seconds

Any ideas what needs replacing and how much it should cost?

sounds like the diaphgram in the divertor valve is shot also whilst your doint that you might as well flush out your heat exchanger with a descaler , this worked for me

Hi, did you solve this problem as ours is doing it now? We had no hot water but I've just tried all the taps together and it works!! Any help would be great!
