Underfloor cooling with ASHP?

MultiFuelBurner

Have run the Ecodan in cooling mode on UFH and it down make the floor cool to the feel on feet and we have used fans to whip up the coolness on very hot days.

We isolate the upstairs as that is all radiators and they would condensate into the carpet etc.

It's worth it for very very hot days but to be honest we are looking an air to air air conditioning this year for three of the major rooms used.
