Real world feel of MVHR +heat system

In a domestic situation I have no experience of barefoot winter use on an unheated  tiled and well  insulated floor.

But the principle is simple enough. If the floor is 25°C or so from absorbing space heating then it won't suck heat from your feet, but that won't be an efficient process.

That's the main issue I think. Ufh is inherently warm and gives you cosy feet then spreads to the air which can be cooler.

 

Floor covering makes a lot of difference. Carpet and LVT throughout here. 

 

Efficient UFH with a floor at 25 deg won't feel much different on your toes from a well insulated slab at 20deg. Not chilly, not hot. UFH in a high flow temp situation is very nice on your feet but it's expensive to run.

I don't see any reason against having both, it's just heat transfer through pipes to the floor or to a fan.

 

Cost and complexity?

I don't agree.

Air to water I think we all know about. Some of that is taken to a plenum to heat air which is pumped into the room and a duct returns it from the other end. Simple but prob not for the typical installer who buys a kit.
