GSW Tankless Water Heater

Model : Envirosense Power Vent 90% Efficient Gas Water Heater

Brand : GSW
Product Description : 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.

Power vent design for installation versatility

- Modular blower, with 120V, 60Hz electrical system (5 amps or less), 6-foot cord with standard 3-prong connector
- Combined horizontal and vertical vent runs terminating through outside wall, using ULC S636 PVC, CPVC or polypropylene pipe as follows:
- 2 ? pipe allows vent runs up to 25 equivalent feet
- 3 ? pipe allows vent runs up to 65 equivalent feet
- 4 ? pipe allows vent runs up to 120 equivalent feet
- Supplied with PVC pipe and elbows to connect heat exchanger outlet to blower, including condensate elbow and drain, and ULC S636 PVC Vent Attenuation Assembly (VAA)

Side-mounted taps for recirculating systems

- Hot and cold "side taps" allow the Envirosense Power Vent to be used for "combination" systems for water heating plus space heating, radiant floor heating or other applicationsrequiring a recirculating hot water loop
- Plugs for recirculating taps are shipped with water heater

Intelli-vent gas control with silicon nitride hot surface igniter

- Premium-grade hot surface igniter eliminates standing pilot
- Electronic circuitry provides superior system diagnostic capabilities plus extremely precise temperature contro

Commercial-grade glass lining with two magnesium anode rods

- Superior protection against tank corrosion
- Glass lining protects all "water side" tank surfaces plus inside of internal heat exchanger exposed to condensate

Diffuser dip tube

- Helps reduce lime and sediment buildup, maximize hot water output
- Cross-link polymer withstands long-term exposure to temperatures up to 400F
