Delivering 94% efficiency, 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 94% 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.
