Compact commercial electric water heater

The Rheem-Ruud EGSP15 is a 15 gal electric water heater built for indoor commercial use at 277 V single-phase. It delivers a maximum recovery flow of 20 gph at a 40 Degrees F rise using a single 2,000 W element and automatic temperature control.

Replaces smaller point-of-use units

This heater upgrades from undersized point-of-use models when a facility needs more stored hot water without moving to a large commercial tank. The jump is worth it when demand exceeds what a compact unit can recover during peak periods.

Simple NPT connections with clearance checks

Cold and hot connections are 3/4 in NPT located at 4.6 in and 21.9 in from the base, so piping aligns with standard rough-ins. The tank diameter is 17.75 in and overall height is 24.3 in; verify the installation niche accommodates those dimensions before mounting.

Questions about this item

What clearance does the 24.3 in tall unit need for the 3/4 in NPT cold inlet at 4.6 in and hot outlet at 21.9 in?

The heater stands 24.3 in high with a 17.75 in diameter tank; the cold inlet sits 4.6 in from the floor and the hot outlet 21.9 in, so allow access space at those heights for 3/4 in NPT connections.

How is the single 2000 W element wired to the 277 V supply, and what step is often missed?

Connect the 7.2 A, 277 V single-phase feed to the element terminals and verify the automatic thermostat is set before energising; the step often missed is confirming the thermostat calibration after wiring.

When should the anode rod be inspected on this 15 gal commercial tank?

Inspect the anode rod annually; with 20 gph recovery at 40 °F rise and 277 V operation, the rod typically lasts two to three years before replacement is needed.
