High-Efficiency Boiler Installation in Mamaroneck, NY

September 25, 2025

At Sustainable Heating & Cooling, we recently completed a high-efficiency boiler installation in Mamaroneck that shows how upgrading old systems can transform comfort, efficiency, and reliability.

Out with the Old: Inefficient, Oversized Boiler

The home originally relied on a large, outdated boiler that was not only inefficient but also took up unnecessary space. The system consumed too much fuel, struggled to keep up with heating demand, and required constant maintenance. The homeowner wanted a smarter, more efficient solution that would lower operating costs and improve long-term reliability.

Twinned High-Efficiency Boilers for Redundancy

Instead of installing just one boiler, we designed a system using two high-efficiency boilers twinned together. This approach provides several key benefits:

- Redundancy: If one boiler ever needs service, the second continues providing heat and hot water without interruption.

- Better Efficiency: During milder weather, only one boiler operates, saving fuel and reducing wear and tear. When temperatures drop, both units work together for maximum output.

- Smart Staging: The system automatically balances the load between the two boilers, ensuring peak performance year-round.

Combined Space Heating and Hot Water

We also consolidated space heating and water heating into one streamlined system. Instead of separate appliances competing for energy, the new boilers provide both domestic hot water and hydronic heating with advanced condensing technology. This not only simplifies the mechanical room but also significantly improves energy efficiency.

Safe Venting with Centrotherm Chimney Liners

For venting, we installed Centrotherm chimney liners down the existing chimney. This upgrade ensures proper exhaust management and prevents any flue gases from being released on the side of the house. By using high-grade venting materials, the system operates safely, quietly, and in compliance with code.

The Result: Comfort, Efficiency, Peace of Mind

The homeowners now enjoy reliable heating, endless hot water, and lower energy bills thanks to their new high-efficiency boiler system. By replacing their outdated boiler with a smart, redundant design, they have peace of mind knowing their home will stay comfortable no matter the season.
