A culmination of 25 years of indirect system manufacturing experience. The SuperStor Ultra Indirect Water 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 boasts 3-5 times more recovery than conventional gas-fired or electric water heaters.
You must have a boiler system in your home to use this product.
This is Harker’s expert opinion on the product as a whole. Intangibles such as durability, ease of repair/install, and value are taken into consideration. We want to make it clear that we do not offer any bad products. Not every product can be used in every situation, so sometimes a 3-star product will be a better fit than a 5-star. All star ratings are pure opinion.
