WATER HEATERS 9 KW THRU 36 KW  
RHEEM-RUUD line of commercial electric  
water heaters come in a broader range of  
models. Our completely redesigned single panel  
control center with hinged door features ready  
access to all controls and elements. With single  
or three phase operation, these units provide the  
most versatile and dependable operation we’ve  
ever offered in a commercial electric water  
heater.

CAPACITIES  
Thick, R-Foam® insulation completely surrounds  
the tank, maximizing heat retention while improv-  
ing energy costs.  
208, 240,  
AND 600  
VOLTAGES  
Features the Lifeguard® high-efficiency stainless-  
steel clad elements for long element life and  
performance.  
Seven different inputs from 9 KW to 36 KW to  
meet most commercial and industrial needs.  
Model Applications  
In addition to being suitable for general commer-  
cial hot water applications, these units 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.

Energy Information  
Rheemglas® commercial electric water heaters are quality engineered to provide the maximum amount of hot  
water available from storage capacity of the tank and energy input of heating elements. Surface mounted  
thermostat models provide water from 120°F to 160°F (50°C to 71°C). Detailed Engineering Information for  
208, 240 and 600 volt models with single or three phase operation will be found in Table A, B or C.  
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.

SYSTEM SENTINEL – All models  
employ a diagnostic panel utilizing light  
emitting diodes (L.E.D.), corresponding  
to the number and location of each  
heating element. L.E.D.’s are energized  
when the electric elements are operat-  
ing. An unlit L.E.D. pinpoints the exact  
location of a non-functioning element,  
making element operation diagnosis  
simple and positive.
