Key Takeaways
•The direct answer: For Melrose oil homes, a heat pump rebate is often worth it, especially in a weatherized home. Massachusetts heating oil costs 73% more than a year ago, according to Mass.gov.
•The whole-home rebate caps at $8,500: According to a 2026 guide to Mass Save rebate rules, it reaches $8,500 at 4 tons.
•The bottom line: Oil owners should book a no-cost Mass Save Home Energy Assessment and switch when their oil system is due for replacement. Gas owners should insulate first and wait until the furnace needs replacing.
Does Your Heating Fuel Decide Whether a Heat Pump Saves You Money?
Largely, yes — and oil is the outlier. Mass.gov's weekly survey puts the Massachusetts average at $6.23 a gallon, up 73% from $3.61 the same week last year.

Here's a quick gut check: multiply last season's oil gallons by today's $6.23 price, then compare that to an installer's estimate of the extra electric cost at Melrose's rate of 27.26 cents per kWh, per PowerOutage.us. The gap between the two numbers is your likely savings.
At Newton's electric rates, the Newton Energy Commission's fact sheet found that oil costs more to run than a heat pump, while gas costs less. The table below draws on that fact sheet.
Oil vs. Gas Heating Decision Factors
Compares running cost, switching rationale, and timing considerations for Melrose homes heating with oil versus gas when evaluating heat pumps.
| Category | Heating With Oil | Heating With Gas |
|---|---|---|
| Running cost vs. heat pump | Heat pump likely cheaper | Gas likely cheaper |
| Main reason to switch | Lower bills, less price risk | Comfort, central AC |
| Best timing | Before your next oil delivery | When the furnace or AC fails |
For oil homes, the case rests on lower bills and is best timed to when the oil system is already due for replacement. For gas homes, it's more about comfort and central air than savings.
Why Does Leaving Oil Pay, and What Can Go Wrong?
The Newton Energy Commission says heat pumps run two to three times more efficient than the best oil or gas systems. Gas still wins on running cost, but against oil above $6 a gallon, that efficiency gap turns into real money saved.
Mass Save's HEAT Loan sweetens the deal further, offering 0% interest on up to $25,000.
The main risk is the house itself. One Newton homeowner kept burning oil until insulation and duct repairs finally let them stop. Weatherization isn't a side item here — it's part of the heat pump project.
Per the 2026 guide to Mass Save rebate rules, whole-home rebates scale with system size, measured in tons, reaching the $8,500 cap at 4 tons. Smaller systems receive less.

To qualify, the home must be weatherized — insulated and air-sealed — with the work done by a Mass Save network installer. The equipment must carry ENERGY STAR Cold Climate certification, meaning it's rated to perform in freezing weather. For 2026 rebates, installation must happen between January 1 and December 31, 2026.
On Gas? Does a Heat Pump Still Make Sense?
For comfort, yes. For savings, usually not.
The Newton Energy Commission found that a typical Newton electric bill has risen $840 since 2015, driven largely by delivery and policy charges that every electric customer pays.
"People can be saving significant amounts of energy, but actually spending a bit more on their utility bills," said Rachel White, a commission member.
Melrose's rate of 27.26 cents per kWh compares to a national average of 17.41 cents, per PowerOutage.us, making the gas comparison even tougher. Still, a heat pump may make sense if you want central air, have solar, or are planning a renovation anyway.
What Are the Strongest Arguments Against Switching?
"Electricity is too expensive."
Fair concern — Melrose pays 27.26 cents per kWh, and heat pump efficiency does drop on brutally cold days. Even so, the Newton Energy Commission found oil still costs more to run than a heat pump at Newton's electric rates, and Cold Climate certification exists precisely for those frigid stretches.
At rates above Melrose's 27.26 cents, or in a drafty house, that gap narrows and could vanish entirely. That's why weatherization and a heating-load calculation (an installer's estimate of how much heat your house needs on the coldest days) come first. Governor Healey's office also notes the state is temporarily removing the SMART charge, a solar-incentive fee, from residential bills — trimming every electric bill for now, though the relief won't last forever.
"Oil prices could come back down."
They could. The 73% jump compares one week to the same week last year, and a single week's price isn't reason enough to rip out a working system. The smartest timing is still when your oil system needs replacing anyway — the Newton Energy Commission notes a whole-house heat pump costs about the same as an oil system plus central air. Electric bills can rise too, so really the choice comes down to long-term exposure to oil's price swings versus electricity's.
What Should Melrose Homeowners Do Next?
If you heat with oil, seriously consider switching when your equipment is due for replacement. Start with a no-cost Mass Save Home Energy Assessment. Insulation runs 75% to 100% off through Mass Save, so weatherize before or alongside installation. Get quotes that include a heating-load calculation, compare the after-rebate cost against net running cost, and confirm current incentive amounts with Mass Save before signing anything.
Governor Healey's office says middle-income oil households can receive up to $680 at mass.gov/heatinghelp. Ask your utility whether it offers a seasonal heat pump rate — at Newton rates, Rachel White estimated such a rate saves owners about $540 per winter, separate from the $840 bill increase mentioned above.
If you heat with gas, wait. Weatherize first, then revisit heat pumps when your furnace or central air nears the end of its life.
