I have a rather acient potterton kingfisher 2 boiler which has always performed well.
I now have a problem and at an inconvenient time as I am trying to move house. Hot water is being forced back up the supply pipe to the boiler storage tank. This results in the overflow sending out water and also the water in the tank gets hot.
I have had all the pipes blown through as it was thought there was a blockage. A new two valve has been fitted as the old one was faulty.
The boiler switches on and of and the boiler thrmosta seems to work OK.
Has any one got any ideas rather than me replacing the system?
