Problem with heating system
I have a closed oil central heating system. Just last year for no
apparent reason the hot press stopped getting hot. I replaced the pump
and the expansion vessel.
I also notice that the pressure at the expansion vessel is quite low -
about 0.5 bar.
I cannot see any leaks
I have blead all of the radiators
All of the radiators heat up properly - except the tank in the hot
press
Please help - Thanks
Rob
