Thank you Tony. I have Worcester Engineer coming on Friday, so I will see what he says. I shall mention the things you said to him.

Sorry, what do you mean by restricted flow?

But don't say you got it off the internet

You guys give more sensible and knowledgeable advice than any plumber I can find in this area!
This forum has been a real eyeopener and I have learnt so much from you all.
But, you are right, probably best not to say I've been looking on the internet. That must be so annoying!!

Yes, but we ( well most ) are boiler engineers and not plumbers!

I know - wish you all lived in North Devon!

Anyway, can I ask what you mean by restricted flow again?

 

[oilman]

Something that's preventing the water getting through as fast as it otherwise might.

 

[suzen]

But in a new boiler, what would cause a restriction? Is it something physical or is it back to the boiler being too big for the job? Thank you.

It might be dirt that has been circulated to somewhere where it has built up and partially blocked somewhere. That could be anywhere, not just in the boiler. As you imply it was OK at first then that sounds likely.

Or it could be dirt in the pump or a valve is not fully open.

Lots of possibilities but all made worse because ther boiler seems far too large for the use.
