70 Gallon - EcoStor Dual Coil Solar Indirect System Heat Exchanger Backup Residential Water Heater

Description for Bradford White S-DC-DW2-70R6SW

This advanced dual heat exchanger design provides superior installation flexibility by allowing combination heat source systems the ability to operate independently or at the same time with each other. The top heat exchange coil is single-wall and the lower heat exchange coil is double-wall. Typical applications are solar, boiler, wood burner, geothermal or space heating.

Features:

• Applications - Dual heat exchangers located inside the tank may be connected to a variety of different heating systems. Solar heating, Space heating, Geothermal heating, and Boiler heating. The above systems can also be utilized in separate, or in combined configurations resulting in greater application flexibility.
• Dual Coil Design - A single wall, 1 1/2" O.D. glass coated (Vitraglas®) carbon steel heat exchanger is located in the upper portion of tank and provides enhanced heat transfer capability. A double wall, 1 1/2" O.D. glass coated (Vitraglas®) carbon steel heat exchanger is located in the lower portion of tank and provides additional protection between the heating fluid and surrounding hot water.
• Internal Single Wall Heat Exchanger?Single Wall 1 1/2" O.D. glass coated (Vitraglas®) steel coil. The coil has a heat transfer area of 14.2 sq. ft. and a stored water volume of 2.5 gal. Maximum supply temperature from the solar collector must not exceed 250°F.
• 1" NPT Front Supply and Return Connections.
• Sensor Wires for Solar Thermistor Connections - Twisted wires are provided under the Upper and Lower covers. These wires have been provided as a means for connecting thermistors to a solar controller (Thermistors and Solar Controller are not provided).
• Integrated Mixing Device - Features an accurate, easy to use hand wheel for adjusting mixed water temperature, a pre-piped stainless steel flexible connector for quick installation as well as optional water connections (1/2" NPT recirculation inlet, 1/2" NPT hot water outlet, 1/4" NPT cold water outlet). This required system is easily installed and ensures a comfortable outlet temperature while providing a steady flow of hot water.
• Factory Installed Hydrojet® Total Performance System - Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
• Vitraglas® Lining - Bradford White water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for our hot water tanks.
• Fully Automatic Controls - Two surface mounted thermostats with high temperature cut-off devices are located in the upper and lower cover locations. Designed for applications such as a boiler where a specific temperature is desired to control a circulator.
• 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 Anode Rods - Provide added protection against corrosion for long trouble-free service.
• T&P Relief Valve - Included.
• Brass Drain Valve - Durable tamper proof design.

NOTE: May require the use of a lift gate. Please note the product weight listed in the specs
