There are two types of radiant floor heating electric and water based systems.
In floor heating too hot.

Radiant floor heating produces room temperatures very close to ideal.
About 75 f at floor level declining to 68 f at eye level then to 61 f at the ceiling.
And of course adding rugs to make walking comfortable block the heat output.
I would take care to keep your radiant heat temperatures in the heating loop under 135 f 57 c.
Thermostats that do not open correctly will cause the room to become too hot.
Radiant heat can be an electrical heating element embedded into a very thin concrete overlay then tiled carpeted or have wood flooring installed over it.
Warm water systems run hot water through pipes to create heat whereas electric underfloor heating heats wiring beneath the floor to generate heat.
In a typical radiant heating system hot water circulating through pipes installed in the subfloor or under it warms the floor and the heat rises.
According to the radiant panel association a radiant heated floor normally feels neutral with a surface temperature usually lower than normal body temperature although the overall.
