Hi i live in a bungalow The problem is air in the system my central heating has had an air lock for years 3 out of 7 rads are cold.
i have bled the rads, drained the system and slowly refilled them bled again, still the same.
this time i am draining the system and filling from the lowest point which is drain off close to the floor.
Hoping the water will push air up and out.
What do you think i will open a drain off valve in the loft to let air out.
Have tried everything i know
Any help please
its not a combi boiler
Thanks Mick
