Oil to Heat Pump Conversion | Westwood, MA

Why Oil to Heat Pump Conversion Is a Smart Move for Westwood-MA Homeowners

Located just 25 miles southwest of Boston, Westwood, MA is a quintessential New England town offering a mix of colonial homes, modern builds, and suburban charm. But with long, chilly winters and rising energy costs, heating your home can put a real strain on your budget—especially if you're still using an oil heating system. 

Many homeowners in Westwood are now looking for better, more efficient ways to heat their homes. That’s where oil to heat pump conversion services from SumZero Energy Systems come in. Switching from oil to an electric heat pump system means enjoying lower heating bills, improved comfort, and contributing to a more sustainable community—all while taking advantage of generous Massachusetts energy rebates.

Oil to Heat Pump: A Cleaner, More Efficient Choice for Westwood Homes

What Is an Oil to Heat Pump Conversion?

An oil to heat pump conversion involves replacing your existing oil-based heating system—whether it’s an oil furnace or oil boiler—with a high-efficiency electric heat pump. These modern systems provide both heating and cooling and are sized to meet the needs of Massachusetts homes, including those built decades ago and updated over the years.

Heat pumps work by transferring heat rather than generating it, which makes them significantly more energy-efficient than oil systems. And unlike oil, they're powered by electricity, which increasingly comes from renewable sources in Massachusetts.

“In Westwood, where winter nights routinely drop into the 20s, a cold-climate heat pump can reduce heating costs by 30% or more, while eliminating the use of oil entirely.” — SumZero Energy Systems

Why Heat Pumps Work Well in the Westwood Climate

The most common concern in New England is whether heat pumps can stand up to the cold. Fortunately, cold-climate heat pumps are designed to operate efficiently even when outdoor temperatures fall into the single digits. This makes them well-suited for Westwood’s winters while offering cooling during the humid Massachusetts summers.

Benefits of Switching from Oil to Heat Pump in Westwood

• Lower utility bills due to improved energy savings
• Year-round comfort with heating and cooling in one system
• Eliminates need for costly oil deliveries
• Reduces indoor air pollutants associated with oil combustion
• Helps reduce carbon footprint and dependence on fossil fuels

Oil Boiler to Heat Pump: Transitioning to a Cleaner Alternative

Differences Between Oil Boilers and Heat Pumps

Oil boilers work by heating water and distributing it via radiators or baseboard units. They rely heavily on metal piping and consistent fuel deliveries. Heat pumps, on the other hand, use refrigerants and electric compressors to transfer heat, resulting in higher efficiency and cleaner operation.

Switching from an oil boiler to a heat pump not only eliminates your reliance on oil but also simplifies your system—you can often replace both heating and cooling equipment at the same time.

What Happens to Radiators and Existing Ductwork?

Depending on your current setup, SumZero Energy Systems can design a heat pump solution tailored to your home structure:

• Ducted systems can be added with minimal modifications if space allows
• Ductless mini-splits are ideal for homes without ductwork and offer room-by-room control
• Hybrid systems can preserve existing elements like radiators during a phased upgrade

“Many Westwood homes found in neighborhoods like Islington and High Street were built before central HVAC was common, making ductless heat pumps an excellent fit.” — SumZero Energy Systems

Cost and Rebates for Replacing Oil Boilers

Massachusetts homeowners can access financial assistance for switching to cleaner alternatives. Programs like Mass Save® offer rebates up to $10,000 for oil heating replacement with high-efficiency heat pumps. There are also 0% interest HEAT Loans for qualifying upgrades.

Replace Oil Furnace with Heat Pump: Financial and Environmental Wins

Major Energy and Cost Savings Over Time

When you replace that old oil furnace with a heat pump, you’re making an investment in long-term energy savings. While oil prices continue to be volatile, electricity is more stable—and in Massachusetts, it's increasingly sourced from renewable power like solar and wind.

Heat pumps are up to 300% efficient, meaning for every unit of electricity used, you can generate three times as much heat. Compare that to oil furnaces, which may operate at just 60–80% efficiency.

“Replacing our old furnace not only stabilized our heating bills but made our home in Westwood noticeably more comfortable and eco-friendly." — Quote from a Westwood homeowner shared by SumZero

Improved Indoor Air Quality and Comfort

Oil systems can release fumes and particulates that harm indoor air quality. Heat pumps improve this by eliminating indoor combustion and reducing allergens and humidity. With zoned systems, homeowners can also enjoy customized comfort room-by-room.

Decarbonization and Local Climate Goals

Westwood is part of a statewide effort to lower greenhouse gas emissions. Converting from oil to a heat pump is a powerful way to reduce your carbon footprint while supporting Massachusetts’ energy goals. It’s a move that aligns with the state’s commitment to achieving net-zero emissions by 2050.
