110 Gallon - 285,000 BTU Shield ASME Commercial Water Heater (LP Gas)

The SHIELD commercial water heater delivers best-in-class innovation from Lochinvar. It operates at 95% thermal efficiency, and provides a 100% effective defense against a water heater's worst enemy - lime scale buildup inside the tank.

Tank type water heaters suffer from one thing the SHIELD does not, lime scale buildup. Lime scale insulates the water from the heat source, decreasing thermal efficiency and increasing operating costs. Just a 1/4" of lime scale will increase fuel consumption and raise operating costs as much as 25%. Shield has no flue tubes inside the tank. The water is heated in a separate stainless steel heat exchanger mounted above the tank. By controlling and creating high water velocity through the heat exchanger, the heat surface areas are kept clean so thermal efficiency remains high, for life.
