I put CH on, on the controller. The HW switch is left off. The radiators will not heat up. I then run the hot tap on the bath. The water is hot. I continue to run this water until it goes cold. The radiators then begin to get warm shortly after.
This is the only way i can get the central...
no, they dont start getting hot until i run the hotwater off. I turn the bath on and when the hot water begins to run cold, i stop the tap. The radiators then start to heat up
Hi, I have a y plan heating system but am not getting any radiators heating up until I've ran off the hot water via the bath.
What could be causing this problem please?
Thanks
