Triangle Tube Smart 30 Indirect Water Heater 30-Gallon Review

The Triangle Tube Smart 30 is a 30-gallon indirect water heater — the smallest in Triangle Tube's Smart line. Designed for very small homes or supplementary fixtures with hydronic boiler systems.

Specs: 30 gallons stored, fully stainless steel tank construction, internal stainless steel coil heat exchanger, polyurethane foam insulation. Lifetime tank warranty (with compatible boiler).

The 30-gallon capacity covers single-person households or supplementary fixtures with hydronic boiler heat source. Triangle Tube's premium stainless construction means superior durability versus mass-market glass-lined alternatives.

About $1,800 unit, $2,600-$3,400 installed depending on boiler integration. Right buyer: small home with Triangle Tube or other premium hydronic boiler in long-stay scenario.
