Compact commercial mini-tank

The Rheem-Ruud EGSP10 is a 10.0 gallon electric water heater designed for point-of-use commercial installations. It operates on a 277 VAC single-phase supply drawing 21.7 amps with a 3,000 watt heating element. The tank measures 22 7/8 inches in overall height and 15 3/4 inches in jacket diameter.

Electrical and plumbing checks

Verify that the site provides 277 VAC single-phase power and a circuit rated for at least 21.7 amps before ordering. Confirm that inlet and outlet connections suit the existing plumbing layout and that the installation location accommodates the stated height and diameter. Ensure local codes permit this unit for the intended application.

Suits high-demand point-of-use

This heater suits commercial settings needing fast recovery at a single fixture, delivering 12 gallons per hour at a 100 °F rise and 10 gallons per hour at a 120 °F rise. It is not for buyers who need whole-building capacity, larger storage volumes, or multi-point supply. Installations requiring a different voltage or three-phase power should look at alternative models.

Questions about this item

Does the EGSP10 ship with plumbing fittings or do I need to buy supply lines and a T&P valve separately?

The unit is a bare tank with 277 VAC wiring terminals; supply lines, shut-off valves and a temperature-pressure relief valve are not included and must be purchased separately.

The spec lists single-phase and three-phase — which one should I choose for a standard 277 V commercial panel?

A standard 277 V commercial lighting panel is single-phase, so select the single-phase connection; three-phase is only for facilities with a 277 V three-phase service.

What does the 12 gph recovery at 100 °F rise mean for back-to-back hand-washing cycles?

It can reheat roughly 12 gallons per hour after a 100 °F temperature lift, supporting several short draws before the 10-gallon tank needs significant recovery time.
