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 Crossover Benefits



The NEW Crossover Commercial is made of durable 316L stainless steel with a hi-fin heat exchanger design for superior performance. It has a durable 316L stainless steel with up to a 3.5 gallon fire tube heat exchanger and provides zero flow activation and scale prevention technology.

The CGH has a thermal efficiency of up to 95% and a UEF of up to .92. With an advanced modulating system this commercial water heater has a 10 to 1 turndown ratio with a very low pressure drop requiring only a small pump to provide maximum output. The Crossover Commercial is eco-friendly and boasts a low NOx combustion system all while maintaining the option to cascade up to 18 units for system redundancy and a large turndown (up to 180 to 1). This water heating system is wall mountable, easily fits into small spaces and is available in both liquid propane and natural gas.

It also includes a Multi-function Control Panel that features a customized temperature control system. These controls work together to make domestic hot water even more comfortable by maintaining constant temperature while the unit is in use.
