With radiant heating installed in concrete floor slabs you re obviously dealing with a large thermal mass so you need a decent temperature differential to have decent heating response hence the 115f boiler setting.
Ideal radiant floor temperature.
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 sensation is one of comfort.
Radiant floor heating systems are significantly different from the radiant panels used in walls and ceilings.

Concrete is much more thermally massive and therefore shouldn t need as high of a temperature i would guess in the 120 125 degree range.
The us doe notes that.
When floors are conditioned within this range most people wearing normal footwear will enjoy having their feet on the floor.

Radiant floor heating can be installed underneath any floor type from tile and stone to carpet to hardwood to help to improve your everyday life and comfort.
We understand floor warming options and many more radiant solutions in this section through the use of reviews as well as real life stories and articles detailing other s experiences with radiant heat.
