Hi
Recently my boiler had a pretty bad leak and I had it repaired (3 way valve replaced, I think!!!).
As the weather has started to get colder I dececided to run the CH just to check it. The boiler runs fine and seems to heat up most of the house rads but I have noticed that once the heat is up to the temperature set on the thermostat the boiler stops heating as normal but then continues to pump, over running. Where as before it would cut out until it was needed again. All it seems to doing is pumping and nothing else, when it should have stopped.
Also it appears that two of the radiators downstairs aren't heating up very well. I've attempted to bleed them of any excess air but this doesn't seem to be the problem. Could it be that they are sludged up and how would i check?
Cheers
