Bradford White DW-2-40-L User Manual
Residential PowerStor2™Series
®
Double-Wall Indirect Water Heater
The PowerStor2™Series®Double-Wall Models feature:
■ Heat Exchanger—Double wall 1
1
⁄2" O.D. glass coated (Vitraglas®) steel
coil. The positive leak path between the two walls of the coil ensures
the potable water will stay separate from the hydronic fluid.
■ Low Heat Exchanger Head Loss—Up to 10 GPM flow, with less than
5 ft. of head loss. Greatly reduces the required pump size for heat
exchange.
■ Factory installed Hydrojet
®
Total Performance System—Cold water
inlet sediment reducing device helps to minimize sediment build up in
tank. Increases first hour delivery of hot water while minimizing
temperature build up in tank.
■ Vitraglas
®
Lining—Bradford White tanks are lined with an exclusively
engineered enamel formula that provides superior tank protection from
the highly corrosive effects of hot water. This formula (Vitraglas
®
) is
fused to the steel surface by firing at a temperature of over 1600°F
(871°C).
■ Fully Automatic Controls—Fast acting surface-mount thermostat for
automatic temperature control.
■ Supply and Return Connections—The 3/4" NPT female connections
are located on the front for both the boiler supply and boiler return.
■ 2" Non-CFC Foam Insulation—Covers the sides and top of tank,
reducing the amount of heat loss. This results in less energy
consumption, improved operation efficiencies and jacket rigidity.
■ Potable Water Connections—3/4" NPT factory installed true dielectric
fittings extend water heater life and eases installation.
■ Two Protective Aluminum Rods—Provide added protection against
corrosion for long trouble-free service.
■ Steel Tank—Heavy gauge steel automatically formed, rolled and
welded to assure a continuous seam for glass lining.
■ T&P Relief Valve—Included.
■ Low Restriction Brass Drain Valve—Durable tamper proof design.
■ AHRI Certified—These water heaters are rated by the Air-Conditioning,
Heating, and Refrigeration Institute to provide accurate performance
data within the standards of the certification. This certification provides
a recognized standard for proper comparison of hydronic appliances.
