I have a problem with my central heating and wonder if anyone here can help.
I recently had a problem with the downstairs radiators where the top was getting warm and the bottom was cold. This turned out to be several years of sludge buildup which I removed sucessfully. However after I have refilled the system it looks like I am having poor circulation problems. The radiator nearest the boiler gets warm but the others remain cold.
I have checked the pump and that seems to be running fine. The system is an S plan with 2 motorised valves. The hot water is working fine, if I push the switch from auto to manual the lever returns to the auto position.
On the CH the motor seems to be fine and moves from manual to Auto when the CH is not requested but when I switch on the CH the level seems loose and freely moves from manual to auto. Is this normal? Or is the motorised valve faulty.
The valve is a honeywell and I can move the head and turn the paddle with my fingers. So I presume that that is OK. Moving the motor and switching on the CH I can see the motor turning.
Any help will be gratefully received
Regards
David
