Modine 832-37

The SuperStor ultra indirect water heat is a culmination of over 30 years of indirect system manufacturing experience. The 316L stainless steel tank resists corrosion and eliminates the need for anode rods, allowing for the system to be virtually maintenance free. The heater draws energy from a boiler and thus does not need its own heat source. Hot boiler water flows through an internal heat exchanger in the tank, heating the domestic water. The SuperStor boasts three to five times more recovery than conventional gas-fired or electric water heaters.

• Stainless steel internal bent hot water outlet tube
• Attractive silver finish cover that resists dents and corrosion
• High output finned cupronickel heat exchanger provides maximum efficiency 11 fins per"
• 316L stainless steel tank for high temperatures and corrosion resistance
• Environmentally safe, CFC free water blown, 2" thick foam insulation allows less than 1/2 deg F heat loss per hour
• Immersion type stainless steel control well
