Underfloor heating and radiator in same room?

[reds42]

I'm looking to rework my kitchen and as part of the work add low profile wet underfloor heating.

Having had a play with heat loss calculators, and given the available floor area not under cabinets and appliances to run heating pipes, I'm not able to get quite enough heating from the floor alone.

Is it possible to combine a wet underfloor heating circuit with a radiator in the same room?

Any help appreciated.

Certainly and that provides a faster heat up than UFH alone.

The rad should be oversized a little and with a TRV so that as the room comes up to temperature the rad turns off and the UFH takes over the heating.

Thanks for that, I was thinking along the lines of an oversized radiator with the lower flow temperature of the UFH.

Good point about fast warmup and the use of a TRV, I hadn't considered that.

I'd assume the radiator could just be connected directly back to the UFH manifold on its own port?

No

No

Why not?

Why not?

Rads are designed to run at a higher temperature than ufh. Drop their temp to ufh levels and you might as well not fit the rad.
It might also mean the rad only working when the ufh is on.

Size appropriately.

Control appropriately.

Quite common practice to have Bathroom towel rails connected directly to the UFH below.

OP, you can close band the pipes on the perimeter of the room, areas with no traffic can operate at a higher surface temperature.

Why not use a fan convector plinth type heater inserted in the kick space?? That would give you a quick blast of heat.
