Lochinvar SQUIRE Stainless SSU80 80-Gallon Indirect Water Heater Review

The Lochinvar SQUIRE Stainless SSU80 is an 80-gallon stainless steel indirect water heater. Premium positioning in Lochinvar's indirect line with full stainless construction.

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

The fully-stainless construction is the SSU 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. Premium pricing reflects build quality. Right buyer: large household with Lochinvar boiler installation, long-stay primary residence (15+ years) wanting indirect DHW with stainless durability.
