Our Expert Review
First-hand experience from our Nassau County installation team.
Triangle Tube pioneered the stainless steel fire-tube heat exchanger technology that revolutionized residential boiler efficiency. Our Trotta installation teams have trusted Triangle Tube for demanding Nassau County applications, particularly in homes requiring both heating and domestic hot water.
The Prestige Excellence and Smart series achieve up to 96% AFUE efficiency with Triangle Tube's signature self-cleaning fire-tube design that minimizes scale buildup. The integrated indirect water heater options provide endless hot water—critical for larger Long Island families.
For homes in coastal communities, Triangle Tube's stainless steel construction resists salt-air corrosion better than traditional cast iron alternatives. The compact footprint fits easily in tight basement spaces common in older Nassau County housing stock.
Local parts availability through F.W. Webb in Hicksville and specialized SMART system training ensures our technicians deliver proper installations and service. Triangle Tube's 10-year heat exchanger warranty provides peace of mind.
PSEG Long Island rebates apply to qualifying Triangle Tube installations, with potential savings of $500-$1,000 on high-efficiency models. The combination of efficiency, reliability, and integrated water heating makes Triangle Tube ideal for whole-home comfort.
For homeowners seeking proven condensing boiler technology with excellent water heating capabilities, Triangle Tube delivers decades of reliable performance.
