with the ever increasing prices in the UK of gas and electricity. People are getting more concerned with how much it costs to heat our homes. With Get A Tradesman regularly being asked by our visitors if it is very easy or how to bleed a radiator in the UK.
When To Bleed A Radiator
Th question you need to ask yourself is, when considering bleeding your radiator/s.
- Is it taking longer for any of your rooms to warm up and for the house to be more comfortable.
- Are you having to spend more money on energy i.e. gas or electricity to warm your radiators up to heat your home up.
- Do you find its taking longer for your radiator to come up to temperature.
Tools You Need When Bleeding Your Radiator
You wont need anything complicated as this is one of the most straight forward and simplest things to do in the house and you will need only 2 items.
- You will need a radiator bleed key. Which can be bought from just about any hardware shop for under £2 – or if you cant get hold of a radiator valve key a flathead screwdriver should still do the job.
- An old cloth or a jug to catch any escaping water as it can get a little wet.
What Is The Radiator Bleed Valve
How Do You Bleed The Radiator
When you have decided you need to bleed your radiators the first is you must turn off your central heating system. And make sure all the radiators are cool or you might get a nasty burn. If you have more than one radiator you wish to bleed. Start with the radiator which is furthest away from the boiler which is downstairs.
Insert the radiator key into the bleed valve and place the cloth underneath to capture any water which may escape from the radiator. Twist the radiator key in a anti-clockwise direction until you hear a hissing sound. As this will be the air escaping and close it again when water starts leaking from the valve. Tighten up the radiator valve again by turning the key in a clockwise direction.
Repeat these steps for all other radiators you need to bleed. When you have finished, turn your central heating back on and check if the radiators are now heating up correctly. And hopefully you should have no cold spots and they should start warming up much more quickly.
How to bleed a radiator without a key
If you can’t get hold of a radiator valve key you can always use a flat head screwdriver. The method you need to take this route is place the flat head into the notches of the bleed valve.]
To bleed the radiator, like with the radiator key turn it in a anticlockwise direction to open the valve, and clockwise direction to close the valve.
Always remember to hold an old cloth or jug under the bleed valve to catch any escaping water. And, turn the heating off before you start this process.
How Is Your Boiler Pressure
Bleeding your radiators can often reduce your boiler pressure. So it is always a good idea to double check if your central heating system needs to be re-pressurised at the boiler.
Your boiler pressure should normally be between 1.0 to 1.5 bars. If it’s less than this, you will need to quickly top up the pressure to get it back into range.
If This Doesn’t Work
If you go through this process and there is still no improvement to heating up your home. Then maybe it is time to calling in a plumber or heating engineer which here at Get A Tradesman we can help you with.
