OK, so info is:
Boiler - Potterton 15HE Promax
Vented system (open tank in loft, immersion in airing cup)
Tank in loft is full of water.
I have bled all radiators (no air present).
I have bled all drain valves (some air present).
The problem:
When the system comes on (either C/H and/or H/W), we get some gurgling noises as the boiler starts to heat up, then some banging noises from the pipes, then the boiler cuts-out out and tries again a few minutes later. I presume this is a safety cut-out caused by over heating or low pressure? All rads except one are cold - the hot one is probably nearest the boiler. Thats it really - help please
So far I have:
Listened to the pump - it does not seem to be working - could this cause the whole problem with both the C/H AND H/W?
Does the one pump drive both the central heating and hot water in a vented system?
Background - I did move a radiator a couple of weeks ago but hardly lost any water and system has been fine for the last 2 weeks.
Cheers for any help!.........
