Rheem-Ruud point-of-use electric commercial water heaters are designed to
provide hot water at the consumption point, eliminating costly temperature
loss in long piping runs.Well suited for a wide variety of applications, point-of-
use heaters are small enough for installation in limited spaces under coun-
ters, mop sinks, cabinets, or any remote area where modest quantities of hot
water are required.They are ideally suited for applications in retail stores,
public restrooms, office washrooms, kitchen and mop or bar sinks.
Construction Features:
• Long life tank design –
proprietary steel formulation with a
unique coat of high temperature
porcelain enamel to maximize
corrosion resistance resulting in a
superior tank design. A patented
R-Tech anode rod provides
advanced technology; equalizing
aggressive water action while
prolonging the effective life of
the anode rod and in turn the
life of the tank.
•
Long life heating elements –
Our patented resistor elements
are designed with a specially
treated, double layer of magne-
sium oxide and copper to
resist corrosion.
•
Efficient design –
Rigid polyurethane foam insulation
provides superior insulating
qualities resulting in reduced
operating costs.
• Optional wall mounting kit –
The wall mounting kit provides an
easy way to mount the unit off the
floor, out of the way for more use-
able floor space in a small area.
Each kit is designed to be used on
walls with 16" stud centers. All
necessary parts are included in
this easy to install kit. (Note:The
2-1/2 gallon model comes stan-
dard with a wall mounting kit.)
•
Automatic temperature
control –
A surface mounted thermostat
automatically cycles on and off to
maintain the water temperature at
a desired preset level.
•
Temperature limiting control –
Automatically and safely cuts off
the power in the unlikely event that
the water temperature exceeds
190°F.
• Temperature and pressure
relief valve –
AGA/ASME rated and factory
installed.
