Power Direct Vent Water Heater

Envirosense® Power Direct Vent Water Heater

The Envirosense® Power Direct Vent is a high efficiency condensing gas water heater. It has a spiral heat exchanger that helps keep hot combustion gases in the tank longer which means the water will heat up faster. This makes it ideal for larger homes with multiple bathrooms or luxury appliances such as whirlpool tubs. The Envirosense® Power Direct Vent is ENERGY STAR® Qualified and with its advanced features, it is one GSW’s premium water heaters.

Enjoy high efficiency.

The 100,000 BTU ENERGY STAR® qualified Envirosense® Power Direct Vent gas water heater is equipped with a fully submerged, spiral-shaped condensing heat exchanger and 50 or 75 gallons of storage capacity. This design provides much greater heat transfer surface than a standard straight flue tube, resulting in 96% thermal efficiency and higher hot water output* than comparable 80% efficient water heaters
