Boiler Installation Costs in Greater Boston

Most boiler installations we complete fall in this range:

Average: $13,500

Low: $10,000
High: $20,000

What Affects the Price?

  • Heating capacity: boilers are sized by BTU output to match your home’s heating needs. Larger homes, older construction and homes with less insulation need a higher-capacity boiler.
  • Efficiency: higher-efficiency boilers turn more fuel into heat and can lower your monthly bills, but they usually cost more up front.
  • Your heating system: radiators, baseboard, radiant floors and hydro-air systems each affect how complex the installation is.
  • Venting and access: high-efficiency boilers often need updated venting or drainage, and a hard-to-reach boiler room can add labor.

Every home is different, so every installation is too. Your estimate will list exactly what’s included with the option you choose.

Steam and Hot Water Boilers

We install both gas steam and gas hot water boilers. Steam systems are common in older Greater Boston homes, and they work differently than hot water systems, so we match the right boiler to the system you have.

3 to 5 Options, Your Choice

We install Rinnai, New Yorker, Williamson and Weil-McLain boilers. For every installation, we give you 3 to 5 options with the pros and cons of each, from high-efficiency models to reliable standard boilers. The decision is always yours.
