"Enjoy hot water on demand, anytime! The Onsen 14L Indoor Gas Tankless Water Heater turns cold water into instant hot water when you want it. Fueled by natural gas, the 14L has an electronic ignition powered by a standard 120v outlet and activated by water pressure & flow.

Compact and energy-efficient, the Onsen 14L is your hot water solution for a 1-bath apartment, tiny home, cabin, or cottage.EXHAUST & INTAKE PIPING NOT INCLUDED.NOT SUITABLE FOR HYDRONIC, CLOSED LOOP, RECIRCULATING OR FLOOR HEATING SYSTEMS."
