Rheem-Ruud Commercial Electric Tank-Type Water Heaters
6 KW THRU 54 KW
Product Overview
Rheem-Ruud Electric Commercial Water Heaters are suitable for general commercial hot water applications and are also ideal for point-of-use installations, eliminating costly temperature loss in long piping runs. A single unit can be used as a booster heater to satisfy the hot water requirements of commercial dishwashers. A single temperature storage unit, when installed with a mixing valve, will supply two temperatures in food service establishments. For larger volume hot water requirements, 2, 3 or 4 units can be parallel manifolded, using optional factory kits.
Construction Features
SYSTEM SENTINEL
An element diagnostic panel, utilizing light emitting diodes (L.E.D.) corresponding to the number and location of each heating element are energized when the electric elements are operating. An unlit L.E.D. pinpoints the exact location of a non-functioning element, making element operation diagnosis simple and positive.
R-FOAM® INSULATION
A rigid polyurethane foam insulation provides superior insulating qualities, improves efficiency. Exceeds R-16 insulation factor. Our patented process of injecting R-Foam directly into the insulating cavity adds additional durability and toughness to the heater jacket. Fiberglass insulation guards against heat loss in the heating element compartment, and provides easy service access.
LIFEGUARD HEATING ELEMENTS
Separate screw-in type elements feature a stainless steel outer sheath of INCO-LOY® 800, 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 efficient transfer of heat, and are easily changed by simply screwing new ones into the tank.
GLASS LINED STORAGE TANK
Heavy duty steel tank protects with double coating of exclusive Rheemglas to resist the corrosive action of hot water. Designed for 150 PSI working pressure. Each tank is supplied with factory installed anode rods for cathodic protection.
WATER CONNECTIONS
Hot outlet and cold inlet are 1-1/2" NPS brass nipples which prevent excessive turbulence of heating water and result in optimum tank draw.
SINGLE PANEL CONTROL BOX
With hinged door, provides immediate access to all electrical components and elements.
TERMINAL BLOCK
All models are equipped with CSA listed terminal blocks for simplicity of installation. This new terminal block will accept either copper or aluminum field connect wire.
Certifications and Ratings
EFFICIENCY
These units have been tested according to procedures specified by CSA and meet or exceed the energy efficiency requirements of ASHRAE Standard 90.1b 1992 requirements for energy conservation.

Diagram Description: The diagram illustrates the physical layout and connection points of the water heater. Key dimensions are labeled A through E. Notable connection points include a 3/4" T&P (Temperature and Pressure Relief) valve, a 1 1/2" hot outlet nipple, and a 1 1/2" cold inlet nipple. The System Sentinel diagnostic panel and an automatic temperature control (for immersion models) are also indicated.
Additional Construction Features
ELECTRICAL CONNECTIONS
Prewired, accessible control box with multiple knock-outs on top and side in size selections to match the Canadian Electrical Code. Sizes range from 1/2" to 2". A grounding screw is provided for attaching an equipment grounding conductor.
STANDARD EQUIPMENT ASME T&P VALVE
This is a double safety valve that relieves when temperature or pressure becomes excessive.
AUTOMATIC TEMPERATURE CONTROL
Water temperature settings from OFF and ranging from 90°F up to 180°F (32°C to 82°C) are maintained by immersion thermostat that insures instant shut off at the selected temperature for safety and economy of operation. One thermostat is supplied as standard. For element steps, up to two additional thermostats can be supplied – see optional controls. Over temperature protection is provided by an immersed high temperature limit control, factory set at 200°F (93°C).
MAGNETIC CONTACTORS
All models equipped with contactors, factory wired for simplicity of installation and economical maintenance throughout life of the unit.
240 VOLT CONTROL CIRCUIT
All units are furnished with a 240 volt control circuit. All controls (thermostats, high temperature limit, etc.) are operated off of this basic 240 volt control circuit.
Optional Equipment
ELEMENT FUSING
In addition to all the above construction features, on immersion thermostat models 9 KW through 54 KW there is internal fusing available that protects all elements, magnetic contactors, thermostats and internal wiring circuits. On immersion thermostat models 24 KW and above, additional thermostats are provided so that the maximum element input will not exceed 18 KW per step. Temperature differential between steps can be set as desired. On 24 through 36 KW units, two thermostats are provided and on the 45 and 54 KW units, three thermostats are provided.
For optional fusing, suffix "F" should be added to the model number. Ex. EG120CF-45KW.
