Hi
hadn't had to use the ch since last year, and due to the motorised valve breaking, had to change it and also the pump due to water shorting it and subsequently burning it out (possibly needs drying out)
Fitted a new valve and pump
When I put the central heating on, the pump appears to run and the boiler fire when it is demanded. This to me appears correct.
However
With just hot water selected the pump appears to run all the time - is this correct?
Thanks
