GSW Envirosense Power Direct Vent

Environmentally friendly storage tank water heaters

The 100,000 BTU Envirosense™ Power Direct Vent gas water heater is equipped with a fully submerged, spiral-shaped condensing heat exchanger and 50 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.

With a 22" diameter, the Envirosense™ Power Direct Vent can be installed in less space than a 75-gallon unit yet delivers greater recovery and lower operating costs.
