  • Energy Star Qualified
    • All models (except GPVX 75L) meet the ENERGY STAR EF requirement and may also qualify for local utility and rebate programs.
    • Dynaclean II dip tube optimizes inlet water pressure to minimize cold water regions within the tank. The self-cleaning action also reduces sediment accumulation on the bottom of the tank.
    • Hot-surface ignitor is more robust and reliable than standing pilot, and reduces energy consumption.
    • Built-in heat traps on the water inlet and outlet reduce the amount of heat lost through piping
    • 2-inch, thick, “Environmentally-Friendly” foam insulation reduces the amount of heat loss and contributes to overall energy efficiency
  • Versatile Power Vent Design
    • All models feature an exclusive 3-position rotatable blower outlet which adds flexibility
    • Combined horizontal and vertical vent runs up to 180 equivalent feet with 4″ diameter venting (ABS, PVC, CPVC and polypropylene)
