The infloor and in-wall heating systems are just recently being re-introduced! 2000+ years later.
Even small buildings in the wilds of england are found with hypocaust tiles. I just saw a video introducing a brand-new underfloor heating system using hot air! The not leaking liquid was a big selling point. Everything old is new again. https://en.wikipedia.org/wiki/Hypocaust |
