John Wood
Envirosense™ Power Vent 90% Efficient Gas Water Heater

The Envirosense™ Power Vent is an ENERGY STAR® qualified, 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 shower after shower... at a continuous flow of over 3 gallons per minute.*
