Hi,
A new problem that has just started with my heating and hot water.
I have a conventional glowworm boiler ultimate 40FF and a 3 port heating hot water valve.
Until yesterday everything worked fine but now my heating switch will not fire up the boiler (the 3 port danfoss valve stays in the hot water position.)
When I switch hot water on it starts the boiler up OK.
When I switch Heating on with hot water on after about 10 minutes the valve moves and the heating starts to work.
If I then turn hot water off the heating will continue to switch on and off OK, but if I switch the hot water on by itself again so the valve moves back to just hot water and then turn hot water off then I can not start Heating on it's own again.
I thought it might be the 3 port Actuator head but I have just changed this for a new one and I still have the same problem, the valve on the 3 port valve was turning reasonably freely behind the actuator head.
Anybody got any ideas please?
Thanks,
Kevin
