how can I fix my central heatingwater filled?not oil filled?
have replaced one radiator and replaced the pump to my system on completion the water in the header tank did not drop therefore not refilling my system what is the problem .why is it not refilling
I would think, air in the system, you need to bleed the radiator, top edge one corner, you will find a square head bolt, it needs to be undone, to allow air out, your header tank will then drop.
