Heating your home isn’t just about staying warm. It’s one of the biggest factors in your monthly expenses and long-term home efficiency. With cold winters, fluctuating fuel prices, and a growing push toward energy efficiency, understanding how different heating fuel types work and what they cost is more important than ever.

We thought it would be helpful to provide a guide, breaking down the most common home heating fuel types, how they work, typical operating costs, and what homeowners should know if they’re thinking about converting from one fuel to another.

How Homes in Massachusetts Heat Today

In Massachusetts, natural gas is the most common heating fuel, followed closely by electricity and oil. 

While oil once dominated the state, electric heating, particularly air-source heat pumps, continues to grow due to improved cold-climate performance and statewide efficiency incentives.

As of the most recent U.S. Census data:

• 52% of Massachusetts households heat with natural gas

• 20% use electricity

• 20% rely on oil or kerosene

• Smaller percentages use propane, wood, solar, or other fuels

This mix reflects Massachusetts’ combination of older housing stock, dense gas infrastructure in many communities, and increasing adoption of high-efficiency electric systems.

Common Home Heating Fuel Types in Massachusetts

Natural Gas Heating

How it works:Natural gas is delivered by a utility and burned in a boiler or furnace. Boilers heat water for baseboards or radiators, while furnaces heat air that’s distributed through ductwork.

Why many Massachusetts homeowners choose it:

• Widely available in much of the state

• Lower operating costs compared to oil and electric resistance heat

• Consistent fuel supply with no on-site storage

Things to consider:

• Not available in every town or neighborhood

• Gas line installation can be costly if service isn’t already present

Typical operating cost:Often among the lowest heating costs in Massachusetts, depending on usage and efficiency.

Oil Heating

How it works:Oil is stored in a tank on your property and burned in a boiler or furnace to produce heat.

Why it’s still common in Massachusetts:

• Very common in older homes

• Strong heat output in cold weather

• No reliance on gas utility infrastructure

Things to consider:

• Fuel prices can fluctuate significantly

• Requires tank maintenance and fuel deliveries

• Higher emissions than gas or electric systems

Typical operating cost: Generally higher than natural gas, though high-efficiency equipment can reduce consumption.

Electric Resistance Heating

How it works:Electric resistance systems convert electricity directly into heat using baseboards, wall units, or electric boilers.

Why some homes still use it:

• Lower upfront installation cost

• Simple systems with fewer mechanical components

Things to consider:

• Higher monthly operating costs

• Less efficient for whole-home heating in Massachusetts winters

• Often best as a supplemental or zone-specific solution

Typical operating cost: Among the most expensive options to run long-term.

Air-Source Heat Pumps (Electric)

How they work:Heat pumps don’t create heat; they move it. Even in cold Massachusetts winters, modern cold-climate heat pumps extract heat from outdoor air and transfer it inside.

Why they’re growing fast in Massachusetts:

• Extremely energy efficient

• Provide both heating and cooling

• Strong statewide incentives available

• Lower emissions than fossil fuels

Things to consider:

• Higher upfront cost than traditional systems

• Proper sizing and installation are critical

• Some homes keep a backup heat source for extreme cold

Typical operating cost:Often lower than oil and electric resistance heat, and competitive with natural gas depending on electricity rates and system design.

Propane (LP Gas)

How it works:Propane systems function similarly to natural gas systems but store fuel in a tank on the property.

Why homeowners use it:

• Alternative when natural gas isn’t available

• Cleaner than oil

• Compatible with high-efficiency equipment

Things to consider:

• Fuel price volatility

• Requires tank storage and regular deliveries

Typical operating cost: Typically higher than natural gas, sometimes comparable to oil depending on pricing.

Wood & Pellet Heating

How it works:Burns wood or pellets to generate heat, either as a primary or supplemental system.

Why some Massachusetts homeowners use it:

• Renewable fuel source

• Can offset heating costs when used strategically

Things to consider:

• Requires fuel storage and manual operation

• Often best as a supplemental heat source

Heating Cost Comparison 

Fuel Type	Relative Operating Cost	Price Stability	Efficiency Potential
Natural Gas	Low	Moderate	High
Oil	Medium–High	Low	Medium–High
Electric Resistance	High	Moderate	Low
Heat Pumps	Low–Medium	Moderate	Very High
Propane	Medium–High	Low	High
Wood/Pellets	Low–Medium	Moderate	Medium

*Actual costs vary based on home size, insulation, equipment efficiency, and usage habits.

Converting Heating Fuel Types in Massachusetts

Many Massachusetts homeowners explore conversions to lower costs, improve efficiency, or move away from oil.

Switching from Oil to Natural Gas

Difficulty: Moderate to High

Key considerations:

• Availability of a gas main

• Oil tank removal or abandonment

• New boiler or furnace installation

Why homeowners convert:Lower operating costs, cleaner fuel, reduced maintenance.

Switching from Oil to Heat Pump

Difficulty: Moderate

Key considerations:

• Electrical service capacity

• Insulation and air sealingWhether a backup heat source is needed

Why homeowners convert: High efficiency, strong incentives, and long-term savings.

Switching from Natural Gas to Heat Pump (Hybrid Systems)

Difficulty: Moderate

Key considerations:

• Allows flexibility during cold snaps

• Gas system serves as backup

Why homeowners convert:Improved efficiency without fully giving up gas.

Switching from Electric Resistance to Heat Pump

Difficulty: Low to Moderate

Key considerations:

• Often a straightforward upgrade

• Major reduction in operating costs

Massachusetts Incentives & Efficiency Programs

Massachusetts offers some of the strongest energy-efficiency incentives in the country, particularly for:

• Air-source heat pumps

• High-efficiency boilers

• Weatherization and insulation improvements

These programs can significantly reduce upfront costs and improve long-term return on investment especially when systems are properly designed for your home. We can walk through your various options after seeing your space and discussing your goals with you.

Final Thoughts

There’s no single “best” heating fuel for every Massachusetts home. The right choice depends on:

• Fuel availability in your town

• Your home’s age and layout

• Upfront vs. long-term costs

• Comfort and efficiency goals

Understanding how each fuel type works, and what it takes to convert, puts homeowners in a better position to make confident, informed decisions that will last for years.
