PRODUCT DETAILS
Bosch GWH C 920 ESC NG Commercial Series High Output Condensing Tankless Water Heater Natural Gas

The highest flow rate model, the GWH C 920 ESC is an ultra-high efficiency modulating-condensing water heater with low NOx emissions. It is AMSE approved and like all of Bosch tankless water heaters, is build to serviceability and durability.

Power and Efficiency

With outputs as high as 11.2 gallons per minute, the Bosch GWH C 920 ESC ultra-high efficiency tankless water heaters can satisfy virtually any demand for hot water. These heaters have inputs greater than the 200,000 BTU/hr limit to be eligible to participate in the Energy Star program, but with a thermal efficiency of 94% they are extremely efficient.

The heater features a reliable Ceramat burner and a modulating gas valve to maintain a constant gas-air ratio. For Bosch, though, reliability and efficiency are not enough. Both of these high-power and compact heaters are designed for low NOx emissions, so they’re kind to the environment as well.

Condensing Technology

One reason for the ultra-high efficiency of these heaters is their condensing technology. Though called the latest in energy efficiency by many, this is actually not new for Bosch. They have been using condensing technology for over 10 years, and were the first company to introduce a condensing tankless water heater in North America. Condensing technology captures more of the heat value of fuel by condensing the water vapor in the flue gases. An additional benefit of condensing is a cooler flue gas, which means these heaters can vent with PVC. Concentric venting is available, which simplifies installation as a single pipe needing only one exterior penetration to the outside carries both intake and exhaust.

Easy Controls

The 920 ES water heater are factory set for an output temperature of 122°F. The control unit, or optional remote control, easily changes output temperatures on the residential model from 100°F to 140°F. The control unit’s key pad interface also provides real-time information of the heater’s performance, including easy access to error codes and diagnostics for troubleshooting.

Ability to Cascade

The residential model features the ability to cascade. Installing multiple units together achieves higher flow rates than with a single unit. A four unit cascade can deliver an incredible 36.4 gallons per minute, enough to satisfy an extremely high demand for hot water.

The Benefits of Going Tankless

Most homes and businesses in North America use a storage tank water heater to provide domestic hot water. A tank water heater keeps water hot 24 hours a day, even while you’re at work or sleeping. A tankless water heater, on the other hand, does not store hot water. It heats the water as needed, cutting out needless energy consumption and reducing water heating bills up 50%.

Bosch ProTanless is designed to last. Made from durable copper, steel and aluminum parts, with nothing to rust or collect sediment, these units have twice the average lifespan of traditional tank water heaters. This gives our landfills a break and makes them the right choice for today’s demanding “Green Building” practices.
