Good afternoon, My Central heating has decided to stay on even when switched off. I have a 20 year old Baxi Bermuda back boiler with a Horstmann mechanical timer/controller. I turned the hot water off and this seems to work, but not the CH, the rads are on all the time. I turned down the stat on the front of the boiler which does help a bit. Any ideas? The boiler hasn't been serviced for over a year as I'm changing the system soon. Thanks, WM
