How to bleed a radiator

Bleeding your radiators is a necessary job if you want to keep your heating system running efficiently and ensure your home is nice and warm. Air can become trapped in the system, interfering with how much heat your radiators can put out, and it needs to be removed. Keep reading to find out how to bleed your radiators.

Bleeding your radiator in 6 steps.

Below, you can find the basic steps on how to bleed a radiator yourself. Keep reading to find more detailed information and expanded steps to follow.

1. Turn your heating off and allow time for it to cool down
2. Take a towel and a jug and place both underneath the bleed valve on the radiator
3. Insert the bleed key and turn it slowly, anti-clockwise
4. Air will escape and you will hear a hissing noise. Close the valve when water starts to come out
5. Repeat on all the radiators in your home
6. Turn your heating back on and check the radiators are heating up properly.

Top Tip: when bleeding multiple radiators, start with the one furthest away from your boiler, as it likely contains the most air. If you live in a house, start downstairs and work up.

What does bleeding a radiator mean?

Bleeding a radiator is the process of removing any excess or trapped air within the system. Air cannot be heated in the same way as water, so it is usually the reason why a radiator feels cold at the top.
The air rises and becomes stuck, so the hot water can only reach about halfway up the radiator. This is highly inefficient and may help to explain why you’ve been experiencing cold spots or draughts in your home, or generally wondering why a room feels a little chilly.
Bleeding your radiators isn’t the same as flushing a system - you’re not removing the water, just letting the air out.
It’s a process that takes just a few minutes, but could improve the efficiency of your heating system and make your home a little toastier.

How do I know if my radiators need bleeding?

You will know if your radiators need bleeding because you may feel a cold spot, or they may take a long time to heat up. They might also make gurgling noises when the heating comes on, which is usually the air moving around in the system.
If you’re unsure, you can try bleeding one radiator to see how much air is in there. You’ll know when all the air is out because the hissing noise will stop and water will appear instead.

How will a new boiler reduce my energy bills?

Efficiency of a boiler is determined by the age and type of unit that you have and, given that up to 60% of our energy bills come from heating our home, an energy efficient boiler can save you serious money on your energy bills.

Boilers are rated A+++ to G based on the ErP (Energy related Products Directive) and a boiler that is rated G could be less than 70% efficient or less, meaning that 30p of every £1 you spend heating your home is wasted!

According to the Energy Saving Trust, the following are examples of annual savings that those with a G-rated boiler could make by replacing it with a new A-rated boiler (gas central heating).

Annual Savings
Detached House: £305�Semi-Detached House: £200�Mid-terrace House: £175�Detached Bungalow: £155�Mid-floor Flat: £95
