If some of your radiators are cold, specifically the ones upstairs then there are a number of things you can try before you call anyone.
Firstly check all the radiators valves are fully open, set them all to maximum. If you’ve tried this and still have some cold radiators then you may need to bleed them.
Bleeding a radiator is simply when you let out any trapped air that could be stuck in your central heating system. The trapped air almost always makes it’s way through to the upstairs radiators as hot air rises in the pipe work. If you get a sufficient amount of air in one radiator it will cause an air lock preventing the hot water from warming the radiator.
So how to bleed a radiator.
- You will need a dry cloth and a radiator bleeding key. You can buy a radiator bleed key from a DIY shop or even some corner shops.
- Turn off the central heating and let the entire system go cold.
- Look on the radiator for a square bleed screw. It’s normally situated at the back or on the side. Look for a square shape recessed in a round hole or similar.
- Insert the bleed key and turn it anti-clockwise slowly.
- If you hear hissing wait until this has stopped, you should start to see a small amount of water coming out of the bleed screw.
- Carefully re-tighten the bleed screw clockwise.
- Check all the other radiators, bleeding them all will help ensure all the air is out of your central heating system.
- If you have a combination boiler, one that heats hot water when you turn the tap on, then your system may be low on pressure. If so find the manual for the boiler or look online, top up the system with water following the manufacturer’s instructions and your pressure issue should be resolved too.
- Turn the heating back on – you should have toasty warm radiators throughout your home.
If not, then it’s time to call a heating engineer.
