leaking radiator valve forced me to drain (indirect) system.
Valve changed and now that I have refilled the system, there is only cold water coming from the hot taps.
The flow from the hot tap is as good as previous, the radiators are red hot, but the pipes around the hot water tank are all stone cold.
I have tried forcing the cold water back into the hot water tap (mixer tap) several times but no joy.
Any help would be much appreciated, thanks.
