Additionally, the rate of heat flow from a heater to the air directly in contact with it is higher when there is a greater temperature difference between the two.

7. Underfloor heating - Wikipedia

   en.wikipedia.org/wiki/Underfloor_heating

   Radiant heat transfer is constant based on the Stefan–Boltzmann constant. Convective heat transfer changes over time depending on the air's density and thus its buoyancy. Air buoyancy changes according to surface temperatures and; forced air movement due to fans and the motion of people and objects in the space. Convective heat transfer with ...
