Underfloor heating should provide comfort without excessively high surface temperatures.
Thermal comfort
A floor that is too hot can become uncomfortable and create uneven conditions in the space.
Material protection
Certain wooden or synthetic floors have a specific maximum temperature limit.
Relation to supply
The surface temperature depends on the supply temperature, pipe spacing, thermal insulation, and the final floor covering.
Control
Proper regulation is based on the study, material specifications, and the actual temperatures of the space.
