A light commercial version of the T-K3, the T-K3-Pro incorporates some features of the T-K3, but with commercial-grade quality materials so it can withstand light commercial conditions. The tankless water heater can be installed mounted on a wall inside or outside, or recessed between two wall studs. It also comes with a direct vent option for areas where indoor combustion air is not available or where chemicals and other substances in the environment can affect the integrity of the unit. The water heater features a thermal rating of 84 percent for liquid propane, and 82 percent for natural gas. It starts heating water at 0.5 gallons per minute (gpm) but can generate an unlimited supply of hot water at a maximum flow rate of 7 gpm. For larger applications and added flexibility, four of these units can be connected together without the need for a system controller.
