91 Gallon - 199,999 BTU Shield Commercial Water Heater (Natural Gas), SWA200N

The SHIELD commercial water heater delivers best-in-class innovation from Lochinvar. It operates at 96% thermal efficiency, and provides a 100% effective defense against a water heater's worst enemy - lime scale buildup inside the tank.

Lime scale buildup insulates the water from the heat source, decreasing thermal efficiency, which increases operating costs. Additionally, the rate of scaling increases with temperature and usage. Just a ¼" of lime scale buildup will cause increased fuel consumption and raise operating costs as much as 25%. Lime scale buildup also requires periodic acid washes in the tank that will simply result in a shorter useful life of the equipment. Because SHIELD has no flue tubes inside the tank, the impact of lime scale is eliminated, ensuring high efficiency and low operating costs throughout its life cycle.

SHIELD uses the industry's most advanced stainless steel heat transfer system. Sealed combustion technology delivers a quiet and environmentally friendly supply of heat to the system. Plus, with drawdown capacity as much as 15% higher than typical tank-type heaters, you get more usable hot water than any other competing models. The result is quiet, long-lasting green performance - life cycle efficiency that keeps saving money, year after year.
