Hi. I have a BIASI 24S combi boiler which has just been inherited with a new house. When there is a demanded, hot water is available and you can hear the boiler firing up. However, it refuses to come on for the central heating. There is no room stat fitted and all other settings on the boiler seem OK, so it should be firing up.
It developed this fault after being switched off for a period of time, so I initially thought it was a jammed pump or something?...
I am looking at a 2 week wait for a plumber in my area to check it out, and the inlaws are freezing, so any help would be really appreciated!
Thanks
