I can't see why this wouldn't work but thought best to ask incase anyone has tried it before or is using it and would care to comment.

So the plan is to install wet UFH in a soon to be built kitchen extension. The ufh will be installed in the whole kitchen area which will be of block and beam construction on the base.

We will be knocking through what is currently a dining room (suspended wooden joist floor) , through to the new kitchen extension and plan to also install wet UFH to this room.

So 2, possibly 3 circuits in 1 zone/space.
Any reason why the associated zone valve and pump of the ufh could not be controlled by the free channel on my Wiser Hub and room stat? The other channel/s on the hub will control radiators in the rest of the house and a hot water cylinder.

As the ufh will be one zone I cannot see that there would be any need for actuators on the on the manifold circuits.

Thanks in advance for any comments and feedback.

NB though that I should add that I have emailed Wiser support asking this question and am awaiting their reply. I am mindful that they have recently released their own ufh control center and that company policy might be to coral customers down this route when is is not strictly necessary.

Quick update for anyone interested...I have spoken to 3 independent online UFH specialists who have all confirmed that yes, so long as the UFH is zoned with a 2-port valve and that that valve and associated pump are wired (via a wiring centre) so as to receive their signal from the spare/separate channel on the controller to the radiator zone then this will work fine.

Also so long as there is only 1 zone (room stat) on the UFH then there is no need for actuators on any of the loops/circuits.
Long as your spare channel on the Wiser is a heating channel yes it'll work fine, can use the Wiser thermostat for temperature regulation, schedule through the app, all good.
If the spare channel is a hot water channel you can still control your UFH via setting schedules in the Wiser app but you'd need an external thermostat for temperature regulation.
