    fixing a radiator that is persistently cold on the top half

    Heating Engineers

    My radiator is cold on the top half. I've tried turning it on and off a few times but the problem is persisting. What else could I try to fix the problem?

    "Check if there is air in the radiator. If you have a combination boiler then the pressure will need topping up afterwards. If this does not solve the problem initially there are further issues."

    "You can try taking the air out the top of the radiator with a bleed key and close it when you get a little nit of water. dont forget to top you system back up with water after."
