Loads of air in central heating.

[Riley]

Yes, but there are two pipes coming out of the front of the cylinder that go to the tank in the loft. One is a feed and one is a expansion pipe(?) from the cylinder isn't it? Could it be sucking in air from the expansion pipe(?).

Thanks.

If it’s plumbed wrong then yes but if it’s worked fine up till now then Doubtful. The pipes out of the front of the cylinder are flow and return from the boiler

It has worked fine until this week. I'm worried that a blockage somewhere will be causing it to suck in air from the expansion pipe(?).

I will have to check tomorrow night as the cylinder in also in the kids bedroom!

Thanks for your help

The reason I asked about the pipe being hot and the water in the f & e being hot is sometimes they can pump over. This will definitely be sucking air in if it is.

5 minutes refilling the f&e tank every time you switch heating off. That is a lot of water going somewhere. Sounds to me like you have a leak in your heating pipework. If it was upstairs you’d see it coming through the downstairs ceiling so it may well be that a heating pipe hidden under the downstairs floor has sprung a leak in the cold weather?

Not a bad shout to be fair.

I did think that but I maybe misread that it was refilling from pumping over??

Worth trying to eliminate the more obvious first I’d say.

Looking in the loft would definitely be easier than lifting boards.

Any downstairs room currently started showing signs of condensation perhaps?

Is that pump in boiler mounted on return?
