Chris, I posted something similar to this yesterday and your reply sounds like a viable explanation to my problem. Couldn't find the topic in FAQ. Cheers

First time for me on this so please bear with me !!?!? All of a sudden when my hot water is on I am finding my radiators coming on too .... not pleasant in this weather !!! Could this be that the three way valve needs replacing or something else ? And is there any easy test to pinpoint it...
