The SW-2-65-L from Bradford White is a PowerStor Indirect Water Heater, 57 gal. It's an indirect domestic hot water heater model. Comes with immersed adjustable Honeywell aquastat, T&P relief valve and (3) aluminum anode rods. 2" non-CFC tank insulation ensures minimal heat loss @ only 0.7°F / hr. 

Features:

• Single-wall heat exchanger Vitraglas enamel lining helps to extend tank and heat exchanger life
• Hydrojet sediment reducing device increases 1st hour delivery and minimizes temperature build-up in tank 2"
• Non-CFC foam covers the sides and top of the tank, reducing heat loss
• (3) Protective magnesium anode rods.
