Residential Tank Heaters - Electric

This collection covers Rheem Professional Classic, Classic Plus and Prestige electric tank water heaters from about 20 to 50 gallons. Models run at 240 volts with 4.5 kW or 5.5 kW elements, in short, medium and tall heights, and some include LeakSense or LeakGuard leak detection and demand response capability.

Size by first-hour rating and household demand, and check the height and diameter against the space. Confirm the circuit voltage, breaker and wire size for the element wattage. Plan for a T&P relief discharge line, a thermal expansion tank on closed systems, a drain pan where required, and seismic straps in areas that need them.
