COMMERCIAL WATER HEATERS

The Breadth Of Innovation

UNRIVALED VENTING VERSATILITY

The Cyclone Xi features power-vent and power direct-vent design, allowing clean uncontaminated air to be drawn directly into the unit with the flue gas products vented conventionally through the ceiling or directly through the wall to the outside.

EASIER TO INSTALL

Because installation space today is almost always at a premium, we’ve designed the Cyclone to install in an absolute minimum of space. The exhaust outlet and fresh air intakes are positioned so the water heater can be placed either in a corner or against a wall.

ADVANCED GLASS LINING TECHNOLOGY

Exclusive PermaGlas® Ultra Coat™ glass lining protects all Cyclone water heaters. PermaGlas Ultra Coat provides superior protection for all inner tank surfaces, as well as for the inside of the heat exchanger, which would otherwise be vulnerable to corrosion from flue gas condensate. The innovative helical coil minimizes weld points to extend tank life.

STRENGTH IN NUMBERS

Cyclone Xi water heaters can be installed in manifolded multiples to serve the highest demand applications in place of boiler systems. For example, four BTH-500s can be manifolded to provide total storage of 520 gallons with an input of 2,000,000 BTU.
