Triangle Tube Smart 80 Indirect Water Heater 80-Gallon Review

The Triangle Tube Smart 80 is an 80-gallon indirect water heater, the larger-capacity variant in Triangle Tube's premium indirect line. Sized for 5+ person households with hydronic boiler installation.

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

The 80-gallon capacity covers large household demand on hydronic-driven DHW. Triangle Tube's premium positioning means superior build quality versus mass-market indirect tanks (Amtrol BoilerMate) — stronger coil heat-transfer efficiency and stainless construction.

About $2,800 unit, $3,800-$4,500 installed depending on boiler integration. Premium pricing reflects build quality and lifetime warranty.

Right buyer: large household with Triangle Tube or other premium hydronic boiler, long-stay primary residence (15+ years) wanting top-tier indirect DHW solution.
