Product Description

The LOCHINVAR L-CGN200080 is a natural gas-fired, tank-type commercial water heater in the CGN Multi-Flue Charger series. It delivers 199,999 BTU/h of input capacity and holds 81 gallons of water in a glass-lined steel tank rated to 150 psi and 180 degrees F. The short configuration measures 27.75 inches in diameter by 67.5 inches tall, making it a practical fit for mechanical rooms with height restrictions. Recovery rate reaches 193 gallons per hour at a 100-degree F rise. Spark ignition and an 80 percent thermal efficiency rating round out the core performance profile. Licensed plumbers and commercial HVAC mechanics are the typical installers for this equipment.

This water heater is engineered for commercial and light industrial hot-water demand. Typical applications include apartment buildings, schools, food service operations, and similar facilities where consistent high-volume hot water delivery is required. The CGN series is built around ease of installation and low standby loss, reducing operating costs in continuous-use environments. The multi-flue design supports flexible venting arrangements through a 6-inch vent connection, which suits retrofit and new-construction mechanical room layouts alike.
