Watertown Boiler Installation Experts

Built for New England Winters
We’ve served the Greater Boston area since 2007, starting with new construction and evolving into the heating experts Watertown homeowners trust. We understand what makes heating systems fail in historic New England homes—and more importantly, how to prevent it. Watertown’s mix of century-old Victorians and modern homes near the Charles River creates unique heating challenges. We’ve installed boilers in basement spaces that were never designed for modern equipment and upgraded systems in homes where the original radiators are older than most companies. That experience matters when winter hits and your family needs reliable heat. Our approach is different. While other companies swap units and hope for the best, we treat every installation as a complete system upgrade, ensuring everything works together for decades of reliable service.

How much does boiler installation cost in Watertown, MA?

Boiler installation in the Greater Boston area typically ranges from $4,300 to $8,500, depending on your home’s size, boiler type, and any necessary upgrades to gas lines or electrical systems. High-efficiency models cost more upfront but can save 15-20% on heating bills over the system’s lifetime. The final cost depends on factors specific to Watertown homes—many require gas line upgrades, chimney liner installations, or electrical work to meet current codes.

High-efficiency condensing boilers work best in Watertown’s climate, offering 90-98% efficiency compared to 80% for older models. Natural gas boilers are most popular due to lower operating costs and reliable fuel supply, though we also install oil and propane systems when gas isn’t available. For Watertown’s older homes, we often recommend system boilers that work with existing radiators while providing modern efficiency and reliability. Combination boilers work well for smaller homes or additions, providing both heat and hot water in one compact unit. The best choice depends on your home’s size, existing infrastructure, and heating needs. We assess your specific situation during our free consultation, considering factors like your home’s age, current radiator system, and available utilities to recommend the most cost-effective solution.
Most boiler installations take 1-2 days, depending on your home’s specific requirements and any necessary upgrades. Simple replacements in homes with existing gas lines and proper electrical connections typically complete in one day. More complex installations requiring gas line work, chimney liner installation, or electrical upgrades may take two days. Watertown’s older homes often need additional work that extends installation time—upgrading gas lines to current code, installing new electrical connections, or modifying existing radiator systems. We identify these requirements during our initial assessment and include them in your project timeline. We work efficiently to minimize disruption to your daily routine while ensuring every component is installed correctly. Emergency installations during winter can often be completed the same day you call, though we recommend scheduling installations during warmer months when possible.

Our warranty covers all installation components—piping connections, electrical work, gas line connections, and system controls. If anything fails due to installation issues within the first year, we return at no charge to make it right. This comprehensive coverage gives you peace of mind that your heating system will work reliably when you need it most. We also offer ongoing maintenance services to keep your boiler running efficiently and prevent problems before they occur. Regular maintenance protects both our installation warranty and your manufacturer warranty, ensuring maximum system lifespan.
