24V Under Floor Heat Mat

rockies63 | Posted in General Questions on

I was watching a Youtube video from RR Buildings where the hosts attended the JLC Building Show and they featured this under floor heating product that looks really good.

This product looks very innovative and seems to eliminate a lot of the problems with using under floor water pipes for heating and the high costs of running a typical electric under floor heating mat.
Has anyone used this product before?

    This falls into the same type of marketing hype you see for radiant heaters. Lot of hand wavy arguments for how they are more efficient. Nobody has found a way to get around basic physics, any resistance heat is 100% efficient, no matter how you run it, how hot it is, you get the exact same amount of heat out per electricity consumed. Doesn't matter how much striping you get with cable heat, the efficiency is exactly the same.

    24V just means there needs to be a power supply to take line voltage to feed it, simply another point of failure. There might be a benefit for the rare folks that have 24V battery with solar where it can save some conversion loses.
