ThermoMate Condensing Tankless Water Heater Propane, Up to 5.28 GPM

A gas tankless water heater is sized by the flow it must deliver at the temperature rise your inlet water demands: read the stated maximum GPM, the BTU/h input, the fuel (natural gas or propane) and whether the unit is listed for indoor or outdoor mounting. Gas supply, venting and combustion air are decided by a licensed plumber or gas installer under your local code, not by a listing.
