The day before yesterday I was at Masada in Israel.
These are photos of bath with radiant floors and walls.
Hot air was fanned under the floor and in ceramic pipes in the walls.

    That's called a "hypocaust", dating back to Roman times. The heat source was a fire, probably wood-fueled.

    Didnt Korea have something similar they called "ondol" but fired with soft coal or something?
