GSW 33 Gal Power Vent Natural Gas Water Heater (100113722)

GSW power vent water heaters are used when conventional chimney venting is not an option. Air is drawn from inside the home while a rotatable motorized blower forces the exhaust outside. This GSW water heater is a very energy efficient model, which saves money on energy costs and is more environmentally friendly. This 40 USG/151 L water heater features: factory-installed heat traps on the water inlet and outlet to reduce the amount of heat lost through piping, improving energy efficiency; exclusive TankSaver design prolongs tank life; robust air intake snorkel inhibits flammable vapours from entering the combustion chamber; sensor detects flammable vapours and automatically disables the unit to prevent ignition; state-of-the-art electronic gas control featuring advanced self-diagnostic capabilities that makes troubleshooting easy; and flexible venting options - can be vented with 2", 3", or 4" ULC s636 PVC, CPVC, or polypropylene pipe up to 180 equivalent feet. This unit is ideal as a replacement water heater in a variety of applications due to its 3-position rotatable blower.
