Underfloor heating beneath floorboards

Circuits are always neutral at the end of a cycle. So what use is the statement?

I bow to the "expertise" and return to the original question of the OP.

Radiant heat/convection: Humans prefer to absorb heat in the same way they lose it. In a mix. Therefore, every pure form as the sole heating method is a bit limited. Moreover, radiant heat decreases in intensity; in a large room, nothing reaches the back. However, it is quite easy to equip a heavy masonry heater with a few warm air loops.

Hi, good friends of mine have underfloor heating. I will find out more about it and get back to you here afterwards.
