The best selling indirect in the market just got a whole lot better...
SuperStor Ultra EVO Indirect Water Heater
The SuperStor Ultra EVO indirect water heater is the next generation of indirects.
We took two of our market leaders, the Superstor Ultra and the SuperStor Ultra Max and combined their best features into the SuperStor Ultra EVO.But we didn’t stop there...
SuperStor Ultra EVO has a redesigned smooth 316L stainless-steel coil, improving overall heat transfer, top and side color-coded connections and an improved thermo-well.
Low Maintenance, Low Costs
The 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 Ultra EVO boasts three to five times more recovery than conventional gas-fired or electric water heaters.
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 EVO is available in 30 / 45 / 60 / 80 / 119-gallon capacities
