Hot Water but no central heating
Posted: Fri Aug 31, 2007 8:37 pm
Hi,
When I switch central heating only on, the pump starts up, the boiler kicks in and I get heating.
However, if I then switch the hot water on as well, I get hot water but then the rads go cold!
I've two motorised valves which seem to activate.
Any thoughts. I have a pumped system.
Thanks,
Mike
