Shield, the Ultimate Green Operation
With inputs up to 500,000 Btu/hr, 96 percent thermal efficiency and storage up to 125 gallons, SHIELD has everything it takes to provide the ultimate green operation – without the risk of lime scale buildup inside the tank. With other commercial water heaters, heat transfer takes place inside the tank through flue tubes or coil-type heat exchangers. As a result, thermal efficiency decreases over time due to lime scale buildup, which gradually drives operating costs up. In fact, as little as one-fourth of an inch of lime scale on the heat exchanger can increase operating costs by 25 percent and cause tank failure in as little as two years.
In fact, we’re so sure that you and your customer will be pleased with the Shield and its
quiet strength; we’ll give you $250 if you’re
not satisfied.
