[@r3playretro]

Before you bleed your radiators, ensure your heating is turned off and your radiators have completely cooled. Although a screwdriver can be used for some modern radiators, most radiators require a radiator key to bleed. ... Once all your radiators have been bled, check the pressure of your boiler gauge.

[@ThePsychicMindofHart]

how do you do that

[@bartkuk1]

It looks like he had the heating on as he was checking the radiator to get warm. So who is telling the truth?

[@BishoujoMegami]

@@bartkuk1 he had it on yes. But he is probably used to it as a professional. I think it's just about being careful not to burn your hands. You won't to get burnt if the heating is off

[@indianjedi]

Thanks for the tip I was wondering if the heating needs to be off or on

[@angels77100]

You bleed the radiator once the heating has been turned on. That way you know the water is being heated through-out the radiator. Who told you to turn the heating off?

[@jaminallen3119]

Thank you! Our new radiator that hasn't worked for months in the airing cupboard is now fully effective!!

[@dtwistrewind7361]

Don't forget to top up the pressure that was just lost if it drops below 0.6 bar on most boilers you will need to top up from the filling loop and reset cycle.

[@XgamerdaveX]

What?

[@Fr3ddyUK]

@@XgamerdaveX When you bleed the radiator. the air escapes. And the water pressure throughout the system is lower than it should be. So you need to get the pressure back up to around 1.2 bar. This makes up for where the air once was. Hope that helps.

[@XgamerdaveX]

Tony Crabb how do you increase pressure. The original comment talks about increasing pressure using a filling loop. I don’t know what that is.

[@Fr3ddyUK]

@@XgamerdaveX Underneath the boiler there should be a tap/lever you either turn or press to increase the pressure. You will know when you turn the correct one, as you will hear the water filling the system back up. Remember when the pressure reaches around 1.2 bar or in the green depending on your boiler. Turn the water off.

Do you have to start from your boiler and work your way down to the last one or do you have to do them separately ?. I have 3 that need bleeding

[@RainWalking]

Great simple fix, thanks

[@SilverlineToolsTV]

Glad it helped

[@budweizer100]

"The Craig!!" (in Avid's voice) What the hell!? Did not expect you to be telling me how to bleed a radiator

[@Gloria_Smess]

After bleeding the radiators don't you have to do something else to introduce more water from the mains into the heating system?

[@christopherstirrup5318]

yes - you need to release the water valve under the boiler to build the pressure back up.

[@angels77100]

Look if you can hear the air escape when you open the valve then there is in most cases no need to leave it open when you turn on the heat. If however no air is released, then turning the heating on is necessary. I've been doing this successfully for countless years, and as a rule of thumb, I always turn the heating on regardless before I start bleeding.

[@IreneWY]

Thank you for this instruction :)

[@SilverlineToolsTV]

Glad it was helpful!

[@IreneWY]

@@SilverlineToolsTV small question, if you don't mind. There was some air in the radiators. But one of them made the hissing air escaping sound while water was dripping out. Is there air inside or what could that be?

@@SilverlineToolsTV Hi, I have noticed my bedroom radiator making gurgling noises and it only heats up half way - this means it needs bleed surely? I think many people forget they need bled. How often do you think radiators last before needing bled? Also with the key, do you turn it anti clockwise to release the air? Thanks.

[@MshTch]

Lovely!

[@SilverlineToolsTV]

Glad you think so!

[@Stardust_Truth_Seeker]

Do you turn the radiators on or off to do this and how long should it be left on if you turn it on? obviously you don't want to get scolded but do you need to have the pressure in the system to bleed the radiators?

Yes it needs re pressuring usually around 1.2-1.5bar
