SuperStor Ultra Water Heater

SuperStor Ultra Water Heater

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.

High Efficiency, Low Costs

SuperStor Ultra Indirect Water Heater

Did you know an indirect water heater is one of the most cost effective ways to heat water? It eliminates the tremendous flue losses associated with gas-fired storage water heaters without the hassles and extra costs of tankless gas water heaters. When used with a modern, high-efficiency boiler these energy savings hold true even in the summer when your boiler isn't needed for heat!

The SuperStor Ultra is a high performance indirect water heater that can generate over 50% more hot water than many water heaters of a similar size. It has minimal heat loss, thanks to a 2" thick environmentally safe water blown foam insulation.

Use the SuperStor Ultra in conjunction with a HTP high efficiency boiler to reduce operating costs even more!

Ultra Performance

The SuperStor Ultra is available in 7 sizes ranging from 20 to 119 gallons. For coil booster models, see SuperStor Ultra Storage Tanks.
