Prices depend on sizing, venting and piping in your home, so we quote every installation.
Discontinued: company ceased operations Nov 3, 2025. If you already own one, we can still service it where parts are available. For a new install, compare current Triangle Tube models or every brand's lineup.
Before buying or servicing a Triangle Tube boiler, confirm current parts and warranty support with the manufacturer or your supply house.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

About the Triangle Tube Instinct Solo
The Triangle Tube Instinct Solo brings Triangle Tube quality to a more accessible price point. At 95% AFUE, this compact wall-mount condensing boiler qualifies for PSEG Long Island rebates while delivering the fire-tube reliability the brand is known for. Nassau County homeowners wanting premium quality without flagship pricing appreciate the Instinct.
The stainless steel heat exchanger carries the same 10-year warranty as the Prestige line, backed by Triangle Tube's reputation for durability. Simple controls make operation straightforward without sacrificing efficiency.
Compact wall-mount installation saves floor space in finished basements and tight utility areas. The smaller capacity range (40,000-110,000 BTU) suits typical 2,000-3,000 square foot Long Island homes.
Energy Star certification and PSEG rebate eligibility make the financial case compelling for homeowners upgrading from older cast iron units.
Our recommendation: The Instinct Solo is the entry point into Triangle Tube quality—ideal for homeowners who want premium brand reliability without the Prestige price tag. Best suited for smaller to mid-size homes with moderate heating loads.

Sizing & Installation Notes
Condensing boilers like the Instinct Solo reach their rated efficiency only when return water runs cool enough to condense flue gases. We check your radiation and design water temperatures so the unit actually condenses in your home, not just on the spec sheet.
Every boiler installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, gas or oil supply sizing, and permit requirements for your town.
