Boiler Replacement Cost: 2026 Price Guide
Plenty of older homes in the Northeast and Midwest still heat with hot-water or steam boilers. A modern condensing or combi boiler can burn far less fuel than a 30-year-old cast-iron unit. Across the U.S., most homeowners pay $5,500 to $12,500.

- The pilot or ignition keeps failing
What Moves the Price
- Condensing or non-condensing boiler
- A combi boiler that also makes your hot water
- Fuel type: gas, oil or propane

- Pumps, zone valves and the piping around the boiler
Common Questions
How long does a boiler last?
A cast-iron boiler can last 25 to 35 years. A modern condensing boiler usually lasts 15 to 20 with yearly service.
Can I replace a boiler with a heat pump?
Yes, with an air-to-water heat pump or a ductless system. The radiators may need upgrading, because heat pumps run cooler water than boilers.
