Propane heating costs Massachusetts homeowners $3,100+/year for a typical home, plus tank rental and delivery fees. A cold-climate heat pump delivers the same warmth for roughly $1,100/year -- saving over $2,000 annually. With Mass Save rebates up to $8,500 and the 0% HEAT Loan, the switch pays for itself fast.

Based on MA fuel prices as of February 2026. Heat pump assumes COP 3.0 (cold-climate average). Actual savings depend on home size, insulation, and usage patterns.
Based on Massachusetts propane at $3.65/gallon and the heat pump electric rate of $0.18/kWh (November through April). Propane assumes a 90% efficient furnace; heat pump assumes COP 3.0 (cold-climate average).
| Home Size | Propane /Year | Heat Pump /Year | Annual Savings |
|---|---|---|---|
Small Home 1,200 sq ft ~550 gal propane/yr | ~$2,000 550 gal x $3.65 | ~$850 4,700 kWh x $0.18 | $1,150 $96/month |
Medium Home 2,000 sq ft ~850 gal propane/yr | ~$3,100 850 gal x $3.65 | ~$1,100 6,100 kWh x $0.18 | $2,000 $167/month |
Large Home 3,000 sq ft ~1300 gal propane/yr | ~$4,750 1300 gal x $3.65 | ~$1,650 9,200 kWh x $0.18 | $3,100 $258/month |
The sticker price of propane per gallon is only part of the story. Massachusetts propane customers face additional costs that make the true expense significantly higher than the fuel price alone.
Most propane companies charge annual rental fees for their tanks. If you own your tank, you still pay for inspections.
Minimum delivery charges, hazmat fees, and emergency delivery surcharges during cold snaps can add up quickly.
Propane prices can spike dramatically during cold winters. Unlike electricity rates, propane pricing is unregulated and unpredictable.
Annual propane furnace/boiler tune-ups, pilot light maintenance, and occasional burner or ignitor replacements.
With a heat pump, there are no fuel deliveries, no tank rentals, no volatile commodity pricing, and no combustion equipment to maintain. Your operating cost is simply your electricity bill, which is regulated and predictable. With the MA heat pump electric rate of $0.18/kWh, your heating cost is locked in at a fraction of propane pricing.
For most Massachusetts propane homes, the switch to a heat pump delivers strong savings. Here is an honest analysis of when it makes the most sense and when to think carefully.
Massachusetts homeowners switching from propane can stack two major rebate programs. The federal 25C tax credit is no longer available, but these direct rebates remain strong.
Mass Save rebates are available to all Massachusetts ratepayers. Income-eligible households may qualify for enhanced Mass Save coverage. The 0% HEAT Loan can finance remaining costs up to $25,000 for 7 years.
The typical conversion takes 4-8 weeks from initial assessment to running system. Here is what happens at each stage.
A Mass Save energy advisor performs a no-cost home energy assessment. They evaluate insulation, air sealing, and current heating system to determine heat pump sizing needs.
Your installer performs Manual J load calculations to determine the correct number of indoor and outdoor units. Cold-climate heat pumps rated to -13F to -15F are specified for Massachusetts winters.
Building permits are pulled from your municipality. Mass Save rebate applications are submitted. Your installer handles the paperwork.
Outdoor condenser units and indoor air handlers are installed. Refrigerant lines are run, electrical connections made, and the system is commissioned. Most installations take 1-3 days.
Once you are confident in your heat pump (usually after one full heating season), the propane system can be decommissioned and the tank removed or returned to the supplier.
When you switch from propane to a heat pump, you will need to address your propane tank. The process depends on whether you lease or own the tank.
Pro tip: Many homeowners keep their propane system as backup during the first winter to build confidence in the heat pump. After one full heating season, most find they never used the propane backup and proceed with decommissioning. NuWatt can coordinate tank removal as part of your project.
Switching from propane to a heat pump is one of the most impactful carbon reductions a Massachusetts homeowner can make.
Equivalent to planting 60-100 trees
COP 3.0 = 3 units of heat per unit of electricity
No flue, no exhaust, no carbon monoxide risk
Burning 850 gallons of propane produces approximately 5.2 tons of CO2 per year. A heat pump powered by the MA grid (which is ~40% renewable and growing) produces roughly 2-3.5 tons of CO2 for the same heat output. As the grid gets cleaner, your heat pump gets greener automatically.
A whole-home cold-climate heat pump system for a typical Massachusetts home costs $15,000-$25,000 before rebates. After Mass Save rebates ($8,500), out-of-pocket costs drop to $6,500-$16,500. Income-eligible households can qualify for enhanced Mass Save coverage. With annual savings of $2,000+ and 0% HEAT Loan financing, most systems pay for themselves in 3-5 years.
Yes. Modern cold-climate heat pumps such as Mitsubishi Hyper-Heat and Fujitsu XLTH operate efficiently down to -13F to -15F, covering the vast majority of Massachusetts winter conditions. Many homeowners keep their propane system as backup during the first winter, then fully switch over.
If you lease your propane tank, contact your supplier to arrange pickup once you no longer need it. Most companies will remove leased tanks at no charge, though you may need to pay a remaining balance on your contract. If you own the tank, you can sell it, have it removed ($300-$800 for above-ground), or keep it for backup use such as a propane generator or stove.
Mass Save offers up to $8,500 for whole-home heat pump installation (plus up to $1,000 in bonuses). The federal 25C tax credit expired on December 31, 2025 and is no longer available. Income-eligible households can qualify for enhanced Mass Save coverage. The 0% HEAT Loan covers up to $25,000 for 7 years.
A typical 2,000 sq ft Massachusetts home using 850 gallons of propane per year (~$3,100/yr at $3.65/gallon) will spend approximately $1,100/yr on heat pump electricity using the heat pump electric rate ($0.18/kWh). That is annual savings of roughly $2,000. Actual savings depend on your home size, insulation quality, and propane contract price.
Per BTU of usable heat, propane is typically 10-20% more expensive than heating oil in Massachusetts. Propane also comes with additional costs that oil does not, including tank rental fees ($50-$150/year) and delivery surcharges. Both fuels are significantly more expensive than a heat pump operating on the MA heat pump electric rate.
Yes. Heat pumps provide both heating and cooling. A ducted or ductless heat pump system replaces both your propane furnace and your air conditioning. Many Massachusetts homeowners find that eliminating separate window AC units provides additional savings and improved comfort throughout the home.
No. The federal Section 25C energy efficiency tax credit expired on December 31, 2025, under the One Big Beautiful Bill Act (OBBBA) signed July 4, 2025. There is no federal tax credit for residential heat pump purchases in 2026. Massachusetts state rebates through Mass Save (up to $9,500 with bonuses) and the 0% HEAT Loan remain available.
