What nice giving people you all are. Thank you. You really can effect peoples lives by your contribution.

As you said close enough mate but I must add if the secondary side is staying open vented then pump in that image is not situated ideally. One would need it to be V,C,P on the flow out on secondary side.

If it’s a combi it’s sealed or they’ve linked the pressure switch out as navs can’t be run ov

We do this because we are passionate about our industry, unfortunately for your friend he employed the services of someone who quite frankly doesn't know the basics and as Shaun mentioned before that's damaging.

Do they do commercial heating systems ?

Not sure but will check out. There appears to be a vast misunderstanding what the roles are between plumbers, heating engineers,
central heating specialists.

Yes. So in that case if secondary side is sealed as well then a vessel of suitable size is required.

Yes, life is full of givers and takers. I find it easier to be a giver as I sleep soundly.
Well done for sorting out my problem.

We've arrived at the problem and can advise on the possible solutions but ultimately it's down to you to find a suitable engineer. Unfortunately knowledge and experience comes at a price, something you and your friend have now discovered.
Can I ask, you said your friend was charged just over 2k, was that supply and fit?

£2400 supply and fit but did not supply commission document or make the system work. They said that the lack
of circulation was due to knackered TRV's and said we would need to pay an extra £1300 to replace the 23 valves
and make the system work as it should.
I agree to the logic that we need to ensure the hot water is pumped around to reach the extremities of the system.
