Advice needed. Issues with underfloor heating and hot water system for new build

[Gray0689]

This one really needs eyes on IMHO.

I agree something just ain't right even apart from the under sizing IMO

:iagree: without 1st hand knowledge there's strange goings on being described...! It'd be handy to have to op's plumber on here to give us the heads up on what they've done so far! Doubt they'd like some of the chatter in the thread mind!

Carrera, I have a good read of this and it's the kind of problem that needs a site visit. It's a shame you are so far from me, I'm in Yorkshire, as I would have liked to have got my teeth into it and solved it for you. Saying that try this:

Turn hot water on, turn one underfloor manifold on upstairs, close all the lever valves at the top left of the photo, see if the cylinder heats, if so you have a severe balancing problem.

This may make no difference but it's worth trying. Modern cylinders have high resistance coils and the circuit to the manifolds will have a low resistance as the underfloor pumps take over the work after that.

Would it not be worth putting some gate valves on before the lever valves to restrict the ufh circ and towel rads to test weather it is drawing the heat away from the hot water, just a cheap option that might get you by until you figure out a more permanent solution

Could just close ball valves ?

Carrera, this must be a record, 140 posts and still not fixed, you need a man who wears his underpants on the outside.

Xmas hols did not help, plumber should be back later this week with consultant and fresh look! Will give an update then if still interested.

i am pushing for low loss header set up, when I spoke to him, he said when required, they use the valliant ones, any they any good? Before I have a further conversation with him later this week when he brings a consultant in to have a look.

Tbh you shouldn't be pushing for anything apart from a working system. My advice would be to stay away from specifying as if it doesn't solve it you he's only doing what you have asked.

This should be his problem to own and run with.

Fair point

Anyways a LLH is a LLH, if you know what I mean it is just a large pipe with connections.

Carrera,

Please take notice of what Howsie says, let the consultant do his job, don't you suggest anything to him, don't even mention you have be on the forum, then you don't need to tell the consultant what suggestions have been made here, personally I wouldn't want all and sundries ideas of what's wrong when they haven't seen the job.

If the consultant is any good he will sort it out, I have not read more than 10 of the post, why because if you haven't got it fixed after 20 posts then its going nowhere, a good heating consultant should come in the house and should have the answers to your problems before he leaves, if he doesn't sack him too!

To fix your problems, we need to be stood in front of the problem, not miles away, it can be done sometimes, but not always.

Tony
