Heating With Oil at $6 a Gallon? What a Heat Pump Really Costs to Run This Winter in Central MA (2026)

By Romario Lela, Lela Homelife · Last updated: October 23, 2026

The short answer: Massachusetts heating oil is averaging about $6.12 a gallon this October. At that price, a properly sized cold-climate heat pump will usually cost less to run than oil this winter, often around 10–35% less for the same heat. It isn't automatic, though. In a leaky house, or with a system that's too small, a heat pump can cost about the same as oil or even more.

What changed this fall

• Oil jumped. Heating oil averaged $6.12 a gallon in early October 2026, up nearly 75% from a year ago, according to state data reported by Utility Dive.
• Heat pump owners get a winter discount. National Grid's heat pump rate runs November 1 through April 30 and cuts the base delivery charge from about 6.8¢ to about 2.5¢ per kWh. National Grid's own examples show about $71 off a November bill for a 3-ton system and about $144 off a January bill for a 5-ton system (The Duck Curve). Eversource and Unitil have their own heat pump rates too (Mass.gov).

Oil vs. heat pump: the simple math

Here's what one million BTUs of heat costs, delivered into your home. At $6.12 a gallon, oil comes to about $52.

• Good install, 30¢/kWh all-in electric rate: about $29, roughly 44% less than oil.
• Typical install, 30¢/kWh: about $35, roughly 32% less than oil.
• Typical install, 40¢/kWh: about $47, roughly 10% less than oil.
• Leaky house or undersized system, 40¢/kWh: about $59, roughly 13% more than oil.

These are worked examples, not quotes. Your electric rate, your house, and your equipment decide the real number. To find your all-in rate, add the supply and delivery lines on your electric bill and divide by the kWh you used.

Example winter: a home that burns 700 gallons of oil pays about $4,280 at today's price. The same home on a typical heat pump pays roughly $2,900 to $3,860 in electricity, depending on the rate. Use your own delivery receipts for your real number.

One honest note: your electric bill will go up with a heat pump. The goal is for your oil bill to drop by more than your electric bill rises.

What it costs to install

For an average Central Massachusetts home, a whole-home oil-to-heat-pump conversion typically runs about $22,000–$23,000 before incentives. That's an estimate, not a quote. The price depends on your house, the size of the system, and any electrical work.

Mass Save's heat pump rebate is $2,650 per ton, up to $8,500, for systems installed by December 31, 2026. On or after January 1, 2027, it drops to $2,350 per ton, capped at $7,500 (Mass Save). With the 2026 rebate, that works out to roughly $13,500–$14,500 out of pocket, and the HEAT Loan offers 0% financing up to $25,000.

Mass Save's budget is also being debated on Beacon Hill right now. Nothing has passed, so we can't say how it ends. What we know is what's on the table today (CommonWealth Beacon).

Is a heat pump right for you?

It's a good fit if you heat with oil or propane, your boiler or furnace is 15+ years old, and your house is insulated or you're willing to insulate it. Mass Save offers 75–100% off insulation and air sealing.

It's probably not for you if you heat with natural gas, your house is drafty and you won't insulate, or you plan to sell within a year or two.

Three tips

• Book the Mass Save Home Energy Assessment first. It's no-cost, and it unlocks the insulation discount.
• Insist on a proper heat-loss calculation. Sizing the system correctly matters more than the brand.
• Don't skip the heat pump rate. If you're not enrolled, you're leaving roughly $70–$145 a month on the table in the coldest months on National Grid.

What about solar?

A heat pump adds electric use, so some homeowners pair it with solar. In Massachusetts that usually means a solar PPA, a 25-year agreement where you pay for the power the panels make. It comes with two options. A 2.9% escalator rises 2.9% once a year, never more, and gives more savings in the first couple of years. It's the best path to including a new roof. A 0% escalator keeps the payment the same for 25 years, with smaller early savings but much greater savings over the full term. A free estimate compares both against your actual bill.

FAQ

Is a heat pump cheaper to run than oil in Massachusetts this winter?

Usually, yes, at around $6 a gallon oil. With a typical cold-climate heat pump and an all-in rate near 30¢ per kWh, heat costs about a third less. In a leaky house or at higher electric rates, the savings shrink or disappear.

Do heat pumps work in Worcester County winters?

Yes. Cold-climate models keep heating well below zero, though they get less efficient as it gets colder. Proper sizing matters most.

What is the National Grid heat pump rate?

A lower winter delivery rate, November 1 through April 30, for homes heated with a heat pump. Mass Save-rebated installs are usually enrolled automatically; others can apply online.

How much is the Mass Save heat pump rebate?

Up to $8,500 for installs by December 31, 2026, dropping to a $7,500 cap on or after January 1, 2027. Check MassSave.com for current terms.

Should I keep my oil boiler as a backup?

Many families do at first. It's a reasonable choice if the boiler is in good shape, and it qualifies for Mass Save's partial-home rebate.
