Towel radiator with underfloor heating - does it get warm?

If a controlled residential ventilation system is present, would it then also work without a towel radiator for the "drying"?

Have towel rails mounted on the wall and done

We have installed an electric towel warmer! It can be controlled completely independently as desired.

Are you absolutely sure that the towel radiator is to be installed in the heating circuit? Maybe this is a misunderstanding and an electric one is being installed?

If not = nonsense from GU.

Depends on which heating system is installed. Gas or heat pump.

Why?
Even with gas, you should not mix radiators with underfloor heating.
The flow temperature is equally low in both cases, and mixer constructions reduce efficiency in both.
