Best Zoning Solution

[Richardthe3rd]

The rads will often be on when the UFH is on e.g. when it's cold. What's the problem exactly?

Do you understand the concept of set-back?? Perhaps I should explain for the hard of thinking; A radiator system is time & temperature controlled OK? However, any UFH system should be set-back controlled on temperature only, so not timed - just temperature highs & lows. You don't want your radiators on during the night, but your UFH heating maybe on. Also, with UFH in some floor constructions, it may be set to go off set-back at 5.00am for the customer getting up at 7.00am.

So, never mix the two types of system on the one zone.

They won't be mixed on the one zone as per my first post on the thread.
As its commonly done.

I should think I'm quite a bit more intelligent than you chap, not usually considered hard of thinking by those who know me. I didn't at any point consider mixing the two systems on one zone even though I know very little about heating systems, unlike you who can easily tell the difference between zwischenzug and zeitnot (Google is your friend).

Ah an expert on heating systems that knows very little about eh, heating systems?!!! That's refreshing to know......

So if you don't have a low loss header, how will you stop heat migration on the common return & still have the HW as the first tee on that return? It could be wrongly commonly done??!!......

By plumbing it correctly as its commonly done without a low loss header.

Please explain how you'd 'Plumb' it correctly?? I'm sure the OP awaits your reply with interest or perhaps not??

I'll bet any money he can figure it out.

Well I hope he gets sorted regardless & I also hope he enjoyed the banter.....
