cheers simon, the statement
If the boiler has been wired incorrectly, it wil sometimes turn on and off with its internal stats, but keep the pump runnning indefinitely.
is pretty much spot on for what it is doing. Valves have been changed so not them, Guess it is time to call plumber...
thanks simon yes it is attached to heating pipework, what is a pump overun and what does electriclly energised mean. Also should i turn setting of pump down?
its the red pump by cylinder if that helps, boiler is glo worm micron twin valve pressurised system and it is drayton lifestyle top of range lp241?
does that help?
2 major questions, i have megaflo cylinder in a 4 bed house, the pump setting is on max should I reduce and what does this do. Secondly my pump doesnt turn off unless I use the fuse switch attached to the control unit. I have replaced valves but this has made no difference. Is it a problem...
