96% THERMAL EFFICIENCY CONTINUOUS HOT WATER
VERSATILE POWER DIRECT VENT
• Today’s homes demand more hot water than ever before, and the 96% efficient power
need. The 50-gallon heater delivers hot water output that exceeds a 75-gallon
atmospheric gas water heater. In fact, the fully condensing design is so advanced, it can
deliver continuous hot water for shower after shower…a continuous flow of over
4 gallons per minute. * Yet is easy to install, with height, diameter and installation
requirements similar to standard power direct vent units.
HELICAL INTERNAL HEAT EXCHANGER
• Completely surrounded by water in tank, provides much greater heat transfer
surface than standard straight flue tube
• Helps produce 96% thermal efficiency, which saves money on operating costs compared to a standard
80% efficient gas water heater
•
over time.
