How to bleed your radiators like a pro

Keeping your home nice and warm, and making sure your heating system is working to its full capacity is a main priority for everyone during the winter. An easy way to ensure your heating is working efficiently is to bleed your radiators of air in the system.

If you notice that the tops or sides of your radiator are not as hot as its body, this is a sign the system needs bleeding. There’s nothing to worry about- it’s not unusual and it is due to the system not being 100% air tight. Be vigilant though- if bleeding your radiators becomes a monthly event it might be a sign of a leak.

We know that not everyone is a born professional, so we’ve prepared some tips on how to bleed your radiator like a pro.

1) First of all, ensure your heating system is off, your radiators are cool and fully turned on.

2) Always start with bleeding the downstairs radiators first. A good practice is to also start with the radiator which is furthest away from the boiler.

3) Repeat Step 2 upstairs, once you’ve finished with the first floor. Remember- the furthest radiator should go first.

4) There might be liquid coming from the air vent, so be sure to prepare a cloth.

5) You’ll also need to locate the radiator key, also known as allen key to open the valve. Hint: it’s normally at the top right side.

6) Turn the key slightly- you might hear the air escaping, and this is exactly the noise you want to hear. You know it’s all going by plan when it transforms into a bubbling sound. When liquid starts coming out of the radiator, quickly tighten the valve until it’s shut and move to the next one.

7) Once you have bled all of your radiators, check the system pressure gauge, which is located on the boiler front, to make sure it’s in the correct range

In case your system is needing a top up or shows high pressure just grab your boiler’s manual and follow the instructions. And voila! The heating system is now bled and working to its full capacity.

If your radiators keep losing heat or suffer from low pressure, following the bleeding this might be a sign of a bigger problem. Of course, now that you’re part of our Care Club there’s nothing to worry about- just give us a call and our engineers will be there for you.
