Zoning UFH.

[Vezza91]

Hi guys, a friend of mine had ufh installed last year and its just been tied into the central heating. Hes asked me to put zone valves in which is something i havent got much experience with. Am i right in thinking i need to put a tee on the flow (one flow for CH and one for UFH) with a zone valve on both?

Thanks in advance.

Zv on one. Use the Orange and grey to switch boiler on and off. (Tie in with other stat)
Fit a balancing valve on the return so u can set up properly. Nowt better than ufh robbing rads

Zone valve on the flow to the ufh or the ch?

You will need one on both ufh and heating so they can be operated separately. Also may need a bypass valve fitting.
