Reliability
• Like all of our water heating products,
Rheem-Ruud hot water supply
heaters are crafted to exacting stan-
dards. Each detail of design, engi-
neering and construction must meet
our criteria for performance and dura-
bility.
• The heat exchanger (1), for example,
is constructed of 100% copper. High
Velocity hydraulics (2) virtually elimi-
nates problems of scaling and corro-
sion within its waterways. The cast
iron headers (3) are glass-lined to
assure that the entire heat exchanger
assembly is resistant to corrosion.
• Every Rheem-Ruud hot water supply
heater features titanium stainless
steel burners (4). They operate quiet-
ly, will not clog or corrode, and have
far greater temperature resistance
than cast iron. The controls (5) are
factory adjusted and completely
enclosed for reliable, automatic
operation.
• The outer jacket (6) is galvanized
and enamel baked for lasting
aesthetics.
Efficiency
• Today’s demands for volume hot water
must be met economically, so we’ve
attempted to use every fuel saving
technique conceivable. The resulting
82% efficiency will save you money in
fuel costs for years to come.
• The integral finned copper tubing
(7) in the heat exchanger provides
nine times more heat transfer area
than smooth tubing. Efficiency is
boosted even further by V-baffles (8),
which redirect the heat across the
finned tubing. The insulated combus-
tion chamber (9) features corner
sealed and interlocking refractory
panels to minimize chamber radiation
losses.
• Economy is further enhanced with a
special energy saving pump control.
This automatic control continues to
pump operation until all usable heat
has been absorbed from the combus-
tion chamber and stored in the tank.
• Access to water heater for inspection
is simple. All Rheem-Ruud hot water
supply heaters feature a heat
exchanger inspection panel (10)
and a removable door to access the
slide out burner drawer (11).
Flexibility
• You’ll find that Rheem-Ruud hot
water supply heaters are perfectly
suited for many commercial, industri-
al and special application needs
requiring economical, reliable sup-
plies of hot water. The optional facto-
ry supplied pump is designed to
handle nearly all water conditions
• Our standard sized water heaters –
nine models ranging from 136,000 to
825,000 BTU – are designed for hot
water supply in commercial applica-
tions. Each model is available for
indoor and outdoor installation. The
outdoor models feature a special
draft system which is wind, rain and
debris-proof.
• Our large sized water heaters –
seven indoor and seven outdoor
models ranging from 926,000 to
1,825,600 BTU – meet the heavier
demand of larger multi-family hous-
ing and commercial applications.
They are ideal for use as summer
replacement water heaters, eliminat-
ing the need to fire large central
heating water heaters merely to sup-
ply domestic hot water.
• All of these Rheem-Ruud hot water
supply heaters are compact and
convenient; they save space, fuel
and installation cost.
