Technical Specifications
Source: manufacturer spec sheet · checked Sep 27, 2026
Some figures come from distributor listings and are still being verified against the manufacturer.
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 Prestige Excellence
The Triangle Tube Prestige Excellence handles the demanding hot water loads of larger Nassau County homes. With output up to 155,000 BTU and 95% AFUE efficiency, this fire-tube condensing boiler is ideal for 3,500+ square foot homes in Syosset, Jericho, and Old Westbury with multiple bathrooms. The variable speed pump optimizes efficiency across the full modulation range.
Paired with a Triangle Tube Smart indirect tank, the Excellence provides virtually unlimited hot water for families with high demand. The advanced outdoor reset adjusts water temperature based on weather conditions, maximizing both comfort and efficiency.
Marine-grade stainless construction makes the Excellence suitable for coastal communities, though it excels anywhere high capacity is needed.
RB Supply and specialty distributors stock Prestige Excellence parts, though availability may take 1-2 days for specialty components.
Our recommendation: The Prestige Excellence is best suited for larger families in homes exceeding 3,500 square feet with 3+ bathrooms and high hot water demand. For smaller homes, the Prestige Solo 110 provides adequate capacity at lower cost.

Sizing & Installation Notes
Condensing boilers like the Prestige Excellence 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.
