Boilers are powerful heating systems that can withstand even the most frigid New England winters, but many local homeowners across the North Shore and Seacoast areas are upgrading to heat pumps for better home efficiency and year-round comfort.
Kearney HVAC installs both heat pump and boiler systems, and our NATE‑certified technicians can help you compare options that meet your home’s specific needs and budget.
Heat Pumps vs Boilers
Efficiency
- Heat Pumps: Move heat instead of creating it, offering more efficient operation. Heat pumps also heat and cool, meaning they can replace your home’s air conditioner as well.
- Boilers: Relies on burning oil or gas to generate heat, which is less efficient and emits harmful carbon dioxide. However, modern boilers can still be a good choice for homes with radiators or baseboard heaters in good condition.
Lifespan
- Boilers and heat pumps have similar lifespans, and both can be expected to last for 10-20 years with proper maintenance.
Maintenance
- Heat Pumps: Require annual heat pump maintenance, but because they both heat and cool, you only maintain a single system throughout the year rather than servicing a furnace and air conditioner separately.
- Boilers: Require annual boiler maintenance and occasional repairs, plus additional AC services.
Safety
- Heat Pumps: All-electric systems that do not burn fuel, leaving no risks related to combustion..
- Boilers: Safe to use when maintained properly, however combustion appliances always come with some risk of carbon dioxide poisoning.
Installation
- Heat Pumps: Ductless mini splits and ducted options that can work with any home design or seamlessly connect with your ductwork.
- Boilers: Simple installation in homes with existing radiators or baseboard heaters.
Environmental Impact
- Heat Pumps: Because they run on electricity, not fossil fuels, heat pumps can help you reduce your carbon footprint.
- Boilers: Burning gas and oil produces greenhouse gas emissions, which contribute to poor indoor air quality. This is especially true for older systems that may burn more oil less efficiently.
Dual Fuel Heating: The Best of Both Worlds
You don’t have to fully remove your boiler to enjoy the benefits of a heat pump. A dual fuel heating system pairs an electric heat pump with a gas or oil furnace or boiler, allowing each to run when it is most efficient. In many homes, the heat pump handles most of the heating and all of the cooling, while the boiler or furnace takes over when the deep winter settles in.
At Kearney, we often recommend pairing a boiler with a Mitsubishi Electric Heating & Cooling System for optimal performance throughout the year. Using heat pumps as supplemental heating allows you to reserve starting up your furnace until it’s truly needed, which can help lower heating cost.
Is a Heat Pump Boiler Replacement Right for Your Home?
Deciding between a heat pump, a new boiler, or a dual fuel setup depends on your home, comfort goals, and budget. There’s no one “right” answer for every home, but Kearney designs and installs heat pumps, boilers, and dual fuel systems, and can help you weigh your options and find a custom solution that fits your needs.
