GAS WATER HEATERS
Superior Heat Transfer
By utilizing the innovative internal heat exchanger coil, the Cyclone HE provides superior heat transfer characteristics,
resulting in an unprecedented 90% thermal efficiency, far beyond a standard water heater design. Gallon for gallon,
the Cyclone HE will heat water for significantly less, resulting in substantial savings on energy costs.
With as much power as larger water heaters in a standard 50-gallon footprint, the Cyclone HE is the natural choice for
upgrading during a renovation. And the versatile power vent design allows combined vertical and horizontal vent runs
of up to 128 equivalent feet. Cyclone HE provides superior savings on energy costs.
