Gas Hot Water Supply Heaters

Available in Indoor and Outdoor Models



136,000 thru 1,826,000 BTU/Hr.

Rheem-Ruud hot water supply heaters are designed to provide hot water service to a variety of commercial applications when used in conjunction with an appropriately sized storage tank. These models are particularly suited for applications that require high inputs and large volumes of stored hot water.

Construction Features:

• Reliable heat exchanger

Design – The all copper

heat exchanger is a single bank, straight-through design with a floating return header immune to thermal shock.

• Energy saving pump

control – The energy

saving pump control is an electric device that allows the operator to set the desired time for the pump to run after the water heater shuts off. With the energy saving pump control the water heater pump is programmed to continue running for an optimum period of time in order to absorb the residual heat from the combustion chamber and

use it in the system.

Certifications and Ratings:

•

Efficiency – These models have been tested according to ANSI

test procedures, and meet or exceed the 82% thermal efficiency requirement of current ASHRAE standards (Part of the Federally mandated Energy Policy Act (EPact)). Also exceeds energy efficiency codes of all states.

•

Safety and Construction – These products are design certified

by the CSA: a) As a Hot Water Supply Water Heater equipped with on/off controls for use in conjunction with a storage tank. b) For operation at 180°F. c) To meet all safety and construction requirements of ANSI Z21.10.3.c) For installation on combustible flooring when used with a combustible floor base, and, or e) for alcove installation. ASME construction is standard on all models.

Certified for a 160 PSI Maximum Working Pressure.

• Compact design –

The low water heater mass design offers substantial savings in weight and cube over most cast iron, steel tube and storage-type water heaters making it ideal for rooftop installations and in tight quarters.

• Minimal heat loss design

– Spark-to-pilot (IID) system is standard on all models.

• Glasslined cast iron

headers –

To handle aggressive water conditions. (Models GBBP/GBB136 feature bronze headers.)

Three Important Reasons to Choose Hot Water Supply Heaters from Rheem-Ruud Commercial Water Heaters

Reliability

Like all of our water heating products,

• Rheem-Ruud hot water supply heaters are crafted to exacting standards. Each detail of design, engineering and construction must meet our criteria for performance and durability.

• The heat exchanger (1), for example, is constructed of 100% copper. High Velocity hydraulics (2) virtually eliminates problems of scaling and corrosion 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 quietly, 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 powder coated 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 combustion 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 pump operation until all usable heat has been absorbed from the combustion 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).

lined headers, easily removable

and interlocked combustion chamber

Flexibility

• You’ll find that Rheem-Ruud hot water supply heaters are perfectly suited for many commercial, industrial and special application needs requiring economical, reliable supplies of hot water. The optional factory 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 applications. 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 housing and commercial applications. They are ideal for use as summer replacement water heaters, eliminating the need to fire large central heating water heaters merely to supply domestic hot water.

• All of these Rheem-Ruud hot water supply heaters are compact and convenient; they save space, fuel and installation cost.
