The Prestige Series hybrid electric water heater from Rheem is Energy Star-rated and its high 3.55-3.70 UEF reduces operating cost. The system is equipped with dry-fire protection, is low-lead compliant and is available in 50, 65 and 80-gallon model sizes. Its ambient operating range – 37° to 145° F – is the widest in its class, the company says. The system offers simple access side connections for easy installation, and its premium-grade anode rod with resistor extends the life of the tank. It can connect to Rheem’s exclusive EcoNet Smart Home System for customizable settings and monitoring from any location. Rheem Mfg. Co.
