How the Crossover Commercial Works



The Crossover Commercial (CGH) works on a counterflow system to provide maximum energy efficiency in a compact design. The CGH works in conjunction with a large storage tank (sold separately) to provide a large colume of hot water without the need of expensive direct fired tanks. Standby loss is eliminated as the CGH unit holds 3.5 gallons of water. Up to 18 units can be installed to provide backup and redundancy, which will terminate the potential for expensive downtime that can happen with large traditional systems.

Crossover Technology and How it Works

The Benefits of the CGH


The durable Crossover Commercial is made of the best 316L stainless steel heat exchanger so performance is never sacrificed. With a thermal efficiency of up to 95% and a UEF of up to .92 this water heater maintains a 10:1 turndown ratio with a very low pressure drop requiring just a small pump for maximum output. The CGH’s digital operating control and display program has made monitoring you water heater operation easier than ever. Install up to 18 units for redundancy and terminate the potential of costly downtime that can sometimes affect large traditional systems. The unit can be mounted on a wall saving you space and also comes available in both Natural Gas and Liquid Propane.
