I have a potterton profile 50 el wall mounted boiler.
Installed about 6 months ago.
3 bed semi - pump in room above boiler - 9 radiators in house - conventional boiler. Set to number 3 1/2(6 is max).
When the hot water comes on only (water timed/heating off) after about 5 -10 mins - extremely loud banging pipes !!!!!! sounds like the whole world is about to blowup.....
If i turn on the central heating this stops the explosions.
I have bled all radiators - no air escaping/all rads hot top and bottom.
ANY IDEAS - what is wrong ? i guess air in system somehow can anyone please help.....
PS How can i tell if my system is gravity fed?/sealed or open vented?
