Spec:
Baxi Bermuda GF Super Boiler
Calor Gas CH with Back boiler, no TRV's or Room thermostats fitted.
1960's house, CH was working a year ago.
Hi I have turned on the CH in a house which has not been used for a year and the rads are cold.
The pump works & I can manually turn it smooth as silk.
I have bled the rads, turned the thermostatic valve underneath the back boiler off & then onto high after 5 mins. The pump runs but the boiler does not kick in although it does if I switch the HW on.
Any advice gratefully received.
