Switching From Oil to a Heat Pump in New Jersey and New York: What Changes
Switching from oil heat to a heat pump means you stop buying heating oil and heat your home with electricity. A heat pump moves heat from outdoor air into your house rather than burning fuel to make it. In New Jersey and New York, most oil-heated homes can make the switch with a cold-climate heat pump. Some keep the oil system as a backup for the coldest days, and others remove it completely. What changes for you is your fuel bills, your equipment, what happens to the oil tank, the incentives you can claim and how your home feels in winter. Here is what to expect.
Who still heats with oil in New Jersey and New York
Heating oil is mostly a Northeast fuel. The U.S. Energy Information Administration (EIA) reports that about 4.8 million U.S. households used heating oil in winter 2023 to 2024, and roughly 82% of them were in the Northeast. In New Jersey, EIA data show that about 6% of households used fuel oil as their main heating source in 2023, compared with under 4% nationally. Many of these homes are older houses in North Jersey, the Hudson Valley, Long Island and the outer boroughs of New York City. They often have an oil-fired boiler that heats water for radiators or baseboard.
How a heat pump is different from an oil burner
An oil furnace or boiler creates heat by burning fuel. According to the U.S. Department of Energy (DOE), heat pumps use electricity to transfer heat rather than create it. That is why they can deliver more heat energy than the electricity they use. The same unit also works in reverse in summer, so a heat pump replaces both your heating and your central or window air conditioning.
Modern cold-climate models are built to keep heating in the temperatures New Jersey and New York see in a normal winter. Efficiency does drop as it gets colder outside, so system sizing and design matter. That leads to the first big decision.
Decision 1: Full replacement or keep oil as backup?
You have two main paths.
- Full replacement. The heat pump is sized to heat your whole home on the coldest design day, and the oil system is removed or permanently disconnected. You stop oil deliveries entirely.
- Hybrid (dual-fuel) setup. The heat pump handles most of the heating, and the existing oil system stays in place for very cold days. ENERGY STAR notes that pairing a heat pump with a backup source can be the most efficient way to heat in very low temperatures. A DOE-published sizing guide adds that keeping the existing system as backup reduces the risk of an undersized heat pump.
A hybrid setup lowers your oil use while keeping a familiar backup. But you still keep a tank, still schedule some deliveries and still maintain the old equipment. A full replacement is simpler to live with, and some state incentives require it, but it needs careful sizing.
Decision 2: Ducted or ductless?
Many oil-heated homes have no ductwork, because the boiler sends hot water to radiators or baseboards. This affects what kind of heat pump fits.
| Your home | Common heat pump option | What to weigh |
|---|---|---|
| Oil furnace with existing ducts | Central ducted heat pump | Ducts may need sealing or resizing for heat pump airflow |
| Oil boiler with radiators or baseboard, no ducts | Ductless mini-splits | Indoor heads on walls; you plan placement room by room |
| Mixed: ducts in part of the house | Combination of ducted and ductless | More design work, but flexible |
DOE has long noted that ductless mini-splits suit retrofits because they need no ductwork. That makes them a natural fit for many boiler homes. For a closer look at that option, see our guide to ductless mini-splits for NYC and NJ homes.
What changes with your energy bills
When you switch, your oil bill falls or disappears and your electric bill rises. Whether you save money overall depends on three numbers: what you pay per gallon of oil, what you pay per kWh of electricity and how efficient your old and new systems are.
Prices in this region are high on both sides. EIA data put average residential electricity prices at about 19.3 cents per kWh in New Jersey and about 24.4 cents per kWh in New York across 2024. Heating oil prices move week to week during the heating season. EIA publishes weekly residential heating oil prices for New Jersey and New York from October through March, so check the latest figure there and compare it with what your own supplier charges.
Because results vary so much from home to home, be cautious with anyone who promises a specific saving without looking at your past oil deliveries, your electric bills and your home. A good estimate starts with your actual fuel use from last winter.
What happens to the oil tank
The tank does not disappear on its own, and the rules differ by state.
- New Jersey. The NJ Department of Environmental Protection (DEP) says closing an unregulated residential heating oil tank, by removal or by abandoning it in place, must be done by a DEP-certified tank closure contractor, with a municipal permit. DEP strongly recommends removing out-of-service underground tanks even when there is no sign of a leak. If you suspect a leak, DEP asks homeowners to call its hotline.
- New York. The NYS Department of Environmental Conservation (DEC) sets closure steps for tanks that are registered with the state, including emptying and cleaning the tank and removing it or filling it in place. Smaller home heating oil tanks can follow different rules, and New York City has its own requirements, so ask your local building department what applies to your home.
If you go hybrid, the tank stays in service. If you go full replacement, plan the tank closure as part of the project and budget for it separately.
Incentives: what is available and what is not
The federal Energy Efficient Home Improvement Credit, which allowed up to $2,000 a year for a heat pump, has ended. The IRS states that the credit is not allowed for property placed in service after December 31, 2025, so a heat pump installed in 2026 does not qualify.
State and utility programs are now where the money is.
- New York. The NYS Clean Heat program, run through the state's utilities, has a category for full-load heat pumps installed together with the decommissioning of the existing fossil fuel system. Under it, the heat pump must be able to meet the whole building's heating load at the design temperature, the project must be a retrofit, and a decommissioning checklist is required. Incentive amounts vary by utility and published figures do not match, so check your own utility's Clean Heat page for the current amount.
- New Jersey. Since July 2021, heating and cooling rebates under the New Jersey Clean Energy Program have been offered through the state's gas and electric utilities. Each utility, such as PSE&G or JCP&L, sets its own terms, including what it offers customers converting from delivered fuels like oil. Our earlier guide covers PSE&G's heat pump rebates in detail.
Rebate terms change often, sometimes mid-year. Confirm eligibility, amounts and paperwork on your utility's program page before you sign a contract, as of the month you plan to install.
The honest downsides
- Upfront cost. A whole-home conversion is a significant project, especially without the federal credit.
- Electric service. Some older homes need an electrical panel or service upgrade to support a heat pump.
- Different feel. Heat pumps deliver steady, lower-temperature heat. If you are used to hot radiators, the change can feel unfamiliar at first.
- Tank closure cost. Removing or abandoning an oil tank is a separate expense in a full conversion.
- Bill uncertainty. Future oil and electricity prices are unknown, so savings estimates should be treated as ranges.
Steps to plan your switch
- Gather last winter's oil delivery records and 12 months of electric bills.
- Decide whether you want a full replacement or a hybrid setup.
- Get a room-by-room heat load calculation, not a rule-of-thumb size.
- Check your electrical panel capacity.
- Read your utility's current heat pump rebate terms and requirements.
- If removing oil, plan the tank closure under your state and local rules.
Frequently asked questions
Can a heat pump fully replace oil heat in New Jersey?
Often, yes. A correctly sized cold-climate heat pump can heat many New Jersey and New York homes on its own. Some homeowners keep oil as a backup for the coldest days.
Do I have to remove my oil tank?
Not if you keep oil as a backup. If you stop using it, New Jersey DEP requires closure by a certified contractor with a municipal permit, and recommends removing unused underground tanks.
Is there still a federal tax credit for heat pumps?
No. The IRS states the Energy Efficient Home Improvement Credit is not allowed for property placed in service after December 31, 2025.
Will my home need ductwork?
No. Homes heated by an oil boiler and radiators can use ductless mini-splits, which DOE notes suit retrofits because they need no ducts.
Will I save money switching from oil?
It depends on your oil and electricity prices and your home. Compare last winter's oil costs with an estimate based on your actual heat load and electric rate.
