No central heating

[Freezing2]

I'm not bad at DIY and certainly not afraid to have a go

What do I need to do lol?

ps looking at the plumbing I don't think I could do any worse, don't who did it but it looks a balls and I'm not a plumber

Try a strong magnet on the vent/feed pipe and particularly where it tees into system pipes.
Your system could be running out of water.
Also be aware that any auto vents fitted on certain pipes can cause air to suck into system when heating is on

I should have added that if the magnet does strongly stick to some parts of the feed, then the pipe might be blocked by magnetite.

As per Best above & I have edited my post 14 above.

I feel a little job for tomorrow coming on!

PS if you can get them buy JG Speedfit Twistlock or similar.

Have fun

Thanks for that Chris I will have a look and see if it all adds up with what I can see, so will I just be basically replacing the cold feed Tee and the vent Tee?

Just had a look and the feed/vent is same pipe, do I need to replace where it Tee's into the system with a new Tee is that what you are saying?

Yes, as little water movement along this combined cold feed / open vent pipe (thats what we call it) the magnetite tends to build up over the years.

If you want to do a proper job you could split them up so you a 15mm (or 22mm) cold feed from the F&E tank & a separate 22mm open vent pipe which just goes over the tank. Keep the cold feed tee closes to the inlet of the pump.

I understand there doesn't look much room for cutting the Tee out between pump and floorboards, they are the soldered fittings that have been used
