Rheem ES50-54-G Heavy Duty 50 Gallons - 98% AFUE - Commercial Electric Water Heater - 3 Year Warranty

Construction Features

• System Sentinel –

immersion thermostat models employ an element diagnostic panel, utilizing light emitting diodes (L.E.D.), corresponding to the number and location of each heating element. This system monitors the on-off function of the electric heating elements.

• Long life ASME tank design –

proprietary steel formulation with high temperature porcelain enamel to maximize corrosion resistance resulting in a superior tank design.

• LIFEGUARD heating elements –

separate screw-in type elements feature a stainless steel outer sheath of INCO-LOY 840, surrounding a Nichrome wire filament, to resist water chemical corrosion and burn-out even in air or sediment…for long element life and long life performance. Elements are directly immersed in the water for maximum recovery efficiency (98%) and are easily changed by simply screwing new ones into the tank. Lifeguard elements feature a three (3) year limited warranty.

• Full port, full flow brass drain valve
• Minimal heat loss design –

  85% of the tank surface area on all Rheem-Ruud Commercial Electric products are insulated with 3"" of rigid polyurethane foam insulation providing superior insulating qualities. Unlike other designs, Rheem-Ruud Commercial Electrics can achieve 85% because of the unique compact layout of the heating elements. this results in heat losses less than the energy used by a 100 watt light bulb during a 48 hour standby period
