HTP SuperStor SSU-80 80-Gallon Indirect Stainless Water Heater Review

The HTP SuperStor SSU-80 is an 80-gallon indirect water heater with fully stainless steel construction. Larger variant of the SuperStor SSU-60. Premium positioning in the indirect category with lifetime warranty.

Specs: 80 gallons stored, fully stainless steel tank construction, internal stainless steel coil heat exchanger, polyurethane foam insulation. Lifetime tank warranty (with compatible HTP boiler).

The fully-stainless construction is the SuperStor differentiator. Stainless tanks don't have lining-breakdown failure mode that ends typical glass-lined indirects at year 10-15. Service life can exceed 25 years.

About $2,800 unit, $4,000-$4,800 installed depending on boiler integration. Right buyer: large household with HTP boiler installation, long-stay primary residence (15+ years) wanting indirect DHW with stainless durability.
