11 GAS WATER HEATERS

Superior Heat Transfer By utilizing the innovative internal heat exchanger coil, the Cyclone® HE™ provides superior heat transfer capabilities, 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.

Burkay® HW 80% thermal efficiency hot water Gas Models supply boilers.

Famous Burkay reliability. Because of their lightweight and compact design, they may be easily transported on a two-wheel dolly replacing large boilers in a much smaller space. Burkay models are for indoor use in installations requiring higher inputs up to 670,000 BTU. They can be manifolded for unlimited fire power.

All Non-Ferrous Waterways n All castings are made of bronze or brass n All water tubes are made from copper n Brazed joints or flare union construction make the boiler immune to the effects of thermal shock and thermal cycling Efficient Copper Coil Combustion Chamber n The combustion chamber is a heat exchanger formed from a two passage coil of tightly wound continuous copper tube n Water circulating through this coil surrounds the main burner and captures the radiant heat n A wrap of insulation on the outside of the coil retains the heat captured by the circulating water Copper Heat Exchanger n Directly above the coil and the main burner is a compact, horizontal, copper fin tube heat exchanger n The flue gases must pass through this efficient heat exchanger before leaving the boiler n This unique design provides maximum heat transfer and proven field durability

Thermal Balancer n Patented pump delay system that allows the boiler and pump to run simultaneously but delays pump LOW LEAD CONTENT shot off at end of heating cycle to remove usable heat from the heat exchanger and reduce the scale forming tendencies of motionless hot water

Codes and Standards n All models meet the thermal efficiency and standby loss requirements of NRCan and current edition of ASHRAE/IESNA 90.1 5-Year Limited Heat Exchanger/1-Year Limited Parts Warranty
