The HL Series Indirect Fired Water Heater has multi-position capabilities making it the most flexible on the market. Installed vertically, either in typical freestanding floor position or on a wall, or horizontally, Phase III HL Model heaters can solve any installation problem.
The Smart Series Indirect Fired Water Heater is made for both residential and commercial use. Smart comes equipped with Aquastat, an internal thermostat that controls the burner's cycle with low and high limit temperatures. Smart also provides a superior heat exchange surface area (1.5 to 2.5 times larger than the typical coil), producing a larger volume of heated water in a shorter period of time. In addition, Smart offers stainless steel construction, optimal insulation, a self-cleaning and self-descaling heat exchanger, and "tank-in-tank" design that stores domestic water at high temperatures, thus preventing bacteria growth. Combined, Smart Series Indirect Fired Water Heater provides an efficient, maintenance-free water heater for the energy-conscious consumer.
