State Patriot 51 Gallon Lowboy Light Duty Commercial Electric Water Heater

A 51-gallon State Patriot lowboy commercial electric water heater for light-duty use where height is limited, such as restrooms, breakrooms and small kitchens. Two 4.5 kW elements on 208V three-phase recover roughly 18.5 GPH at a 100 F rise.

The short, wide profile fits under counters and in cramped mechanical rooms while still holding 51 gallons. Medium-watt-density elements with zinc-plated copper sheaths run non-simultaneously as standard, for 4.5 kW connected load, about 15,354 BTU/h. Surface-mount thermostats adjust from 120 to 181 F and include a manual reset high-limit, and a factory terminal block speeds wiring.

The glass-lined steel tank uses a sacrificial anode rod, and foam insulation keeps standby loss low enough to meet DOE and ASHRAE/IES 90.1 requirements. Working pressure is 150 psi, and the factory supplies a T&P relief valve rated to CSA/ASME. Water piping attaches to 3/4 in. NPT top connections fitted with heat-trap nipples. The diameter is about 26-1/2 in., and the heater is UL/CSA listed.
