Radiator systems are used in the UK, and if you haven't had to use radiators to heat your house before, they may seem quite daunting to have to use and maintain.

Is your house cold? Is the heating not on when it should be?

Does the top of your radiator feel cooler than the bottom? 

Check that your radiators are in good working order by bleeding the radiator(s). Fortunately, this only takes 10 minutes and can be done in 5 easy steps.

How to bleed a radiator:

  • 1. Turn off the heating/boiler
  • 2. Get the radiator key
  • 3. Open the valves slowly to let the air out (bleed) until water spurts out
  • 4. Catch the drips by placing a small bowl underneath the valves
  • 5. Repeat these 4 steps on all radiators

  • If you have these common problems with heating and radiators:

  • the radiators in the house all stay cold
  • boiler is working but radiators stay cool
  • some rooms are too hot, some rooms are too cold
  • bleeding a radiator
  • there is a complete loss of heating

  • Or, if you need more information on how to diagnose:

  • cold radiators
  • cool radiators in one part of the house
  • a radiator that isn't warm enough
  • a radiator that stays cold in some parts
  • a leaking radiator
  • See the section on Heating and Radiators for more helpful advice and information

    See How to Bleed a Radiator for visual and clearly written step-by-step instructions


    Arrive Homes provides each of its houses with a radiator key. This key works for all the radiators in the house. If it needs to be replaced, for whatever reason, you can purchase a radiator key from any hardware store, such as B&Q, Homebase, Wickes, and any local independent store, priced at a very low cost since radiator keys often go missing for most and need replacing.

    If you think that the problem is the boiler, see Heating&HotWater Boiler Problems.

    If the boiler or its pipes are leaking, see Heating&HotWater Leaks.

    If there is no hot water or water pressure, see Heating&HotWater Hot Water Problems.

    If there is a gas leak or problem with gas meters or connections, contact Arrive Homes immediately. Turn off the gas valve as soon as you find the problem.

    Rattling or noisy pipes? See Heating&HotWater Boiler Problems to troubleshoot, resolve and/or report a description of the issue.

    Do you have a mold problem caused by a leak? Depending where the leak is, the Arrive Homes maintenance site can help. Locate the problem first.

    Here are some Useful Tips:

    Is the heating and hot water both shut off? Check the pressure gauge on the boiler. The pressure needle should be pointing somewhere between 1 and 2.

    Is the timer properly set on the boiler? Check the timer is set to be on.

    See How to Set a Digital Timer on a Thermostat:

    If you want to find out How to Set an Analog Timer on a heating system, you can use this video as a guide:

    Always shut off the water valve before diagnosing or fixing a hot water problem.

    Place an old rag or a small bowl under the valve to prevent water dripping on the floor.

    If you have checked the radiators in the house, the timer and thermostat settings and the pressure on the boiler, and you have made the attempts needed to try and fix the problem, and you are still experiencing problems with heating or your boiler, report a description of the problem by filling in a maintenance form.
