Hi I have a potterton house warmer55 back boiler I have radiators but no hot water? I was recommended to put the hotwater on only, and as High as possible this seems to work, but only very slightly?
is there anything else that I can do to possibly shift this air block which I got after draining the system???
please help and many thanks in advance....
