Hi everybody. My sister has a problem. I've noticed that most of her rads are hot at the bottom and cold at the top. When I bleed them some air comes out and then nothing, no more air. After the air finishes coming out it is not followed by water, as I'd expect. Nothing at all happens. Should I be bleeding them with the system OFF as I am doing? Or should I turn the system ON and then try bleeding. The rads are fed by a combi boiler and this "air problem" has been prevalent since the combi was installed about a year ago. Any ideas? Thanks, mr J
