Hello there! I am new here so be gentle!
I have just ripped out my old oil combi and replaced it with a eurostar which I bought off ebay (bit risky I know!) they said there was a problem with the heating. when I turned it on it worked fine, doing everything it should. But I later noticed the rads cooling and on inspecting the boiler the heating wouldn't come on whatever I did. I used the fault finding in the book and it pointed to the relay, which I took off and wiped terminals etc. it then worked ok. could it be an intermittant fault on the relay? is this relay bypassed in some way on initial start up? because if I turn off and on it seems fine.
sorry for the long winded post, hope I make sense, Ben.
