What is a Propane Tankless Water Heater?
Though it might seem to be a new innovation on the American market, the propane tankless water heater has been in existence for decades. The device first gained popularity in Europe and parts of Asia in the 1970s, but has only gained a foothold in the United States with rising energy costs and a movement toward environmental awareness. Also known as instantaneous or on-demand water heaters, propane tankless water heaters also exist in versions powered by electricity and natural gas.
