Underfloor Heating Is Electric Or Hydroponic
Underfloor heating originated in Neoglacial times. This was discovered by archaeologists who were excavating digs in the Aleutian islands in Alaska. Trenches lined in stone were found under the floors of subterranean living spaces. Fires were built in them to heat the stones. Subsequently, when this heat rose, it entered and warmed the living spaces of these prehistoric inhabitants.
