How to Repressurise Your Central Heating System

Thanks, fixed the pressure issue, cleared the low pressure error and saved a call out for an engineer.

I did this the other day but unfortunately I dropped the bloody screwdriver once I had opened it up and I don’t see very well so by the time I had found the screwdriver and closed it the pressure was far too high! I had to google what you were supposed to do about it but of course the answer was to just keep bleeding the radiator until enough water came out to lower it 👍🏻

Thanks so much Roger you bailed me out here. Had a rad off the wall, refitted it and bled it but half way through it stopped venting. Of course the accumulator had lost all its pressure. Thanks again for all that you share 🙏

Brilliant. We've been having boiling hot 1st & 2nd floors - but cold 3rd floor rooms for more than 1 year now and tried removing air again yesterday and some did come out, but then what little heat was coming out, stopped altogether and so checked the pressure and just above 0!!! so turned off the heating + boiler and filled as advised and within seconds we had full radiator heat coming out of all the radiators on the 3rd floor + more air came out, and that's with the heating + boiler still turned off, so huge thank you! Especially with these crazy gas/electricity prices and what's being predicted in Apr '22.

very useful thank you; we have a Rayburn eco system which comprises Oil boiler and Rayburn solid fuel stove today I have had to open the two valves a number of times to restore the pressure so wondering if there's something else wrong; pressing the valve on top of the pressure vessel doesn't result in water spraying our so the diaphram would appear to be ok (4 1/2 years old)..

Thanks man really helped me out

Thank you for this video ❤

thanks so much for sharing this. got my heating back working after I bled the radiators

Excellent, problem solved immediately!

Good instructions rodge 👍👍

Great video clear and concise 🤠👍🔨

Hi there these sytems always have 2 valves that you have to turn i seem to only have one of the cold water feed? thanks

Great video:) A had to do that quite often with my old boiler. My new baxi just has a single green lever thing that you just pull down, really easy. The old fittings started leaking in the end. Cheers

when would you reconnect the flexi pipe roger

Thanks for sharing this. But my system doesn't have these two taps. It is completely separated from the water supply. How do I repressurize then? On the towel dryer radiator in the bathroom, on the very bottom end there's some sort of tap. Do I have to let water in down there? I'm a total noob at this, sorry.

Hello, But what about if no filling loop no expansion red tank present??

Amazingly timed video Roger. Just had to do that very thing this evening. Unfortunately water appears to be coming out of the hose now and given that it's bed time, I've opted for the "basin-under-it" trick until the morning. Any suggestions on a fix anyone?

Lifesaver 👍🏻😁

Thanks.

i moved into an old house with an open fireplace. I've been told there is a "back boiler" which heats the water and radiators when the fire is lit . There is a switch which apparently pumps the hot water into the radiators ? The fire is lit i switch on the pump (i can hear bubbling noise) but no warm radiators or hot water . Can someone explain, why not ?
