hi all
Recently changed a friends central heating pump for a more powerfull one, which solved the initial problem of radiators in his new (large) conservatory not getting warm, his room stat was also a bit dodgy, falling foul of being badly located on the stairs! so replaced that with an identical one, problem is now that he reckons the pump is always on, even when the programmer is set to off for both water and heating, I know the pumps normally overun when the boiler shuts down but i cant understand why its on all the time. Any suggestions welcome.
