- 9 – 54 kW input
- 80 or 119 gallon capacity
- Single or three phase
- Designed for use as a recovery heater having its own storage tank
- Meets the standby loss requirements of the U.S. Department of Energy and current edition of AHRAE/IES 90.1.
- Energy efficiency per IEC 60379:2007 is 93.7 %
- Heavy-duty medium watt density elements (three/immersion heater) have incoloy sheathing: provide excellent protection against oxidation and scaling.
- Glasslined tank. Two sizes: 72 and 105 gallon capacity. Tank interior is coated with glass specially developed by A. O. Smith for water heater use. Tanks rated at 150 PSI (1034 kPa) working pressure
- Protects all elements, thermostats, and internal wiring circuits against excess current flow. Meets National Electrical Code requirements that non-ASME tanks must have internal fusing when current draw exceeds 48 amps. Available as an option on Canadian built heaters.
