Radiators Assistance

  1. What should I do if my radiators aren't working?
    • Take a look at your manufacturer guidelines. They'll give you more help on how to do these checks if you're not sure.
    • Double check your system's switched on.
    • Turn your radiators thermostatic valves or radiator valves up as high as they can go.
    • Try bleeding your radiators. Even though it's unlikely that'll affect all radiators. But if you try it, make sure you've switched off your system so you don't burn yourself and never completely take out the bleed screw.
  2. What should I do if my radiator's leaking?

    If we cover your radiators, you'll need to book one of our engineers but in the meantime, you can try limiting the damage with the steps below.

    • Turn off your central heating.
    • Turn your mains cold water tap off.
    • Turn off the valve at each end of the radiator.
    • Find a container, like a bowl or a towel, to catch the water. If you need to, you can direct the water into the container by tucking a plastic bag behind your radiator.
    • Wait for the system to drain. Water will keep leaking until it's drained out.
  3. Why is my radiator making a noise?
    1) Whistling

    You can sometimes make the whistling stop by turning the radiator valves fully on - you'll need to turn the valves anticlockwise. It sometimes happens when the water flow rate is either too high or too low.

    2) Ticking

    A ticking radiator is completely normal - it's just the radiator warming up or cooling down. If it's coming from under the floor, it's probably pipes expanding and rubbing on the floor or joists. It's nothing to worry about.

    3) Tapping or Hammering

    You should get in touch with the person who installed it to get them to fix it. It usually happens if someone hasn't fitted a thermostatic radiator valve properly. So if you've moved a radiator or had a new one put in recently, it could be that the valves might have been swapped over by accident.

  1. How do I bleed my radiator?
    • Turn your central heating and hot water off to be safe. Make sure it's not on a timer.
    • Put your dry cloth under the radiator to catch any water that might come out.
    • Find the square bleed screw. It'll be at the top of your radiator, either on the side or at the back.
    • Put the bleed key into the screw and slowly turn it anticlockwise until you hear a hissing noise. But make sure you don't do more than one and a half turns - you don't want the screw to come out completely. If it does, don't panic, turn the radiator valves off at both ends, and find something to catch the water before putting the screw back in.
    • Wait until the hissing stops and you start to see small amounts of water coming from the bleed screw.
    • Tighten the screw again. But make sure you don't over-tighten it.
    • Now you can switch your heating back on.
