GSW Envirosense Power Vent
Environmentally friendly storage tank water heaters

The Envirosense™ Power Vent is a 50-gallon, 76,000 BTU gas water heater, equipped with a fully submerged, spiral-shaped condensing heat exchanger. This design provides much greater heat transfer surface than a standard straight flue tube, resulting in 90% thermal efficiency and higher hot water output than standard 78% efficient water heaters.
With a 22” diameter, Envirosense™ Power Vent can be installed in less space than a 75-gallon unit and delivers greater recovery and lower operating costs. The Envirosense™ Power Vent is so advanced, it can deliver “endless hot water for showers” ... a continuous flow of over 3 gallons per minute.*
* 3.07 GPM continuous flow, based on 65ºF inlet water temperature and 110ºF outlet water temperature.
