HTP SuperStor SSU-60 60-Gallon Indirect Stainless Water Heater Review

The HTP SuperStor SSU-60 is a 60-gallon indirect water heater with full stainless steel construction. Premium positioning in the indirect water heater category — competes with Amtrol BoilerMate at higher build quality and lifetime warranty.

Specs: 60 gallons stored, fully stainless steel tank construction (versus glass-lined steel in most competitors), internal stainless steel coil heat exchanger, polyurethane foam insulation. Lifetime tank warranty (when paired 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 indirect tanks at year 10-15. Service life can exceed 25 years.

About $2,400 unit, $3,200-$4,000 installed depending on boiler integration. Premium pricing reflects the build quality.

Right buyer: home with HTP boiler installation, long-stay primary residence wanting indirect DHW with stainless durability. The lifetime warranty makes the premium pricing pay back over 20+ year horizons.
