This Floor System Heats Your Home for FREE. Why Did the West Bury It?

Frank Lloyd Wright knelt on a heated floor in Japan in 1914, stood up, and wrote that there was no other ideal heat in existence. He spent the next 45 years incorporating radiant floor heating into his most significant buildings. The industry built 90 percent of American homes with ductwork anyway. In this video, we trace the 2,000 year engineering history of ondol, the Korean underfloor heating system that predates the furnace by two millennia, and break down the physics of why heating air is the least efficient way to warm a room occupied by people who live at floor level, not ceiling level. We also dig into the postwar construction decision that locked American residential building to forced air ductwork, why the simultaneous rise of the air conditioning industry made that lock-in financially irreversible, and how a $30.4 billion HVAC market built around 15 year replacement cycles and recurring service contracts has very little interest in a system with no moving parts, no filters, and a 50 year service life embedded in a concrete slab. We walk through what a modern hydronic radiant floor system actually costs, how its 25 to 30 percent efficiency advantage over forced air translates to real money across a decade of utility bills, and why South Korea has installed this as the unquestioned residential standard in every home regardless of income bracket while American contractors are still selling you a furnace that loses 30 percent of its output through sheet metal ducts running through unheated spaces. #energysaving #heatingbill #windowinsulation #windowfilm #homeimprovement #energyefficiency #savemoney #diy #winterproofing #homeenergy #utilitybills #departmentofenergy #energystar #homeinsulation #frugalliving
