What o rings for this heat exchanger

[A_Novice]

Hi guys,

I'm ordering a refurbished heat exchanger for my Potterton Performa 24 ECO HE.

What o rings do I need for this?

Have someone coming next week to fit and just want to make sure I have all of the bits.

Thanks

Don't waste your time buying refurbished primary heat exchangers...much of these "refurbished" descriptions are nothing of the sort...just a brief external clean up. eBay refuse to enforce accurate descriptions.

Even if an attempt has been made there's no way they can guarantee the cleaning will have restored the part to near new condition. Inside the tubes will almost certainly be turbulator wires...coiled wire to cause water turbulence for better heat transfer...and the small gaps between them will not be clean.

The fact that this part entails work within the combustion chamber means that your work does not comply with the forum rules and should be entrusted to a registered gas installer..no sensible installer would fit secondhand parts sourced by a customer.

A gas safe registered engineer is doing the work. I haven't yet ordered the part but thanks for the heads up.

I am aware who can do the work within combustion chamber and that is why I haven't gone near it.

I may source a new part depending on price. I don't want to replace my boiler just yet.

I haven't read the forum rules for a while but asking what parts I need to order for a professional to then install surely doesn't breach these.

Better to ask him/her what you need then they can't complain when they turn up.

Thanks will do.

Rofl.No sane gas fitter would be up for that.

You haven't said what the problem is. What makes you think a replacement h/ex will cure it?

It is leaking. You can see green stuff where it leaks. Only leaks when the boiler has cooled for around 4 hours.

OK, just curious. Make sure it's not a seal leaking!
