Heat Pump vs. Oil Furnace: Which Costs Less Over 10 Years? 2026 Calculator
For many New York homeowners, replacing oil heat is not just an efficiency decision.
It is a long-term cost decision involving two energy prices that behave very differently: electricity and heating oil.
A heat pump can eliminate or sharply reduce heating-oil consumption while also providing air conditioning.
But installing a heat pump can require a substantial upfront investment, and New York electricity prices are relatively high.
So the useful question is not simply:
Is a heat pump more efficient than an oil furnace?
It is:
Will the energy savings and other avoided costs be large enough to justify the conversion over the years you own the system?

Planning estimate only. Heating load, seasonal COP, installation prices, maintenance and $4.00/gallon oil are illustrative assumptions. The 29.49¢/kWh electricity default uses EIA's June 2026 New York residential average.
Why Oil Heat Matters More in New York
Heating oil is a relatively small part of the national residential heating market, but New York is different.
According to the U.S. Energy Information Administration, Census data showed that nearly 16% of New York homes used heating oil as their primary heating source in 2023.
The U.S. average was only about 4%.
That makes the economics of replacing oil heat with a heat pump particularly relevant for homeowners in New York and the broader Northeast.
How Heat Pump Heating Cost Is Calculated
A heat pump does not create all of its heat through electric resistance.
It moves heat from outside the home to the inside.
Its efficiency can be expressed using coefficient of performance, or COP.
Annual Heating Load in BTU ÷ 3,412
Heat Pump Electricity
Useful Heat kWh ÷ Seasonal COP
Annual Heating Cost
Heat Pump kWh × Electricity Rate
Using the calculator's illustrative 60 million BTU heating load:
60,000,000 ÷ 3,412 ≈ 17,585 kWh of useful heat.
At a seasonal COP of 2.7:
17,585 ÷ 2.7 ≈ 6,513 kWh of electricity.
At 29.49¢/kWh:
6,513 × $0.2949 ≈ $1,921 per year.
How Oil Heating Cost Is Calculated
Heating oil contains approximately 138,500 BTU per gallon for the simplified energy calculation used here.
But an oil heating system does not convert every BTU in the fuel into useful heat inside the home.
That is why the calculator asks for system efficiency.
Useful Heating Load ÷ Oil-System Efficiency
Heating Oil Gallons
Required Fuel Input ÷ 138,500 BTU per gallon
Annual Oil Cost
Gallons × Heating Oil Price
Using the same 60 million BTU heating load and an illustrative 85% oil-system efficiency:
60,000,000 ÷ 0.85 ≈ 70.6 million BTU of fuel input.
That works out to approximately:
510 gallons of heating oil per year.
At the calculator's illustrative $4.00/gallon:
510 × $4.00 ≈ $2,039 per year.
Why the Heating Oil Price Should Be Your Own Delivery Price
Heating-oil prices can move substantially.
EIA's weekly residential data illustrate the point.
For the week of March 30, 2026, EIA reported a New York residential heating-oil price of approximately $5.874 per gallon.
That is much higher than the calculator's $4.00 illustrative default.
The calculator intentionally does not present one volatile spot or seasonal price as the permanent New York assumption.
For a homeowner making a real decision, the better input is the effective price from recent oil deliveries.
Example: What Happens at $5.87 Per Gallon?
Keep every other example assumption the same and change only heating oil from $4.00 to approximately $5.87 per gallon.
Estimated oil use remains around:
510 gallons per year.
But annual fuel cost becomes roughly:
510 × $5.87 ≈ $2,994 per year.
That is almost $1,000 more per year than the $4.00/gallon example.
This demonstrates why a heat-pump-versus-oil comparison can change significantly as fuel prices move.
New York Electricity Is Expensive Too
Oil prices are not the only important variable.
New York residential electricity is also expensive relative to the national average.
EIA reported a June 2026 New York residential average of approximately 29.49¢/kWh, compared with a U.S. residential average of 18.34¢/kWh.
That is why a New York homeowner should not assume that replacing oil with a heat pump automatically produces an extremely low electricity bill.
The result depends on both:
New York electricity price × actual seasonal heat-pump performance.
Oil Price vs. Electricity Price: The Break-Even Question
This is the heart of the financial comparison.
A heat pump becomes more attractive as:
- Heating-oil prices increase
- Heat-pump seasonal efficiency increases
- Electricity prices decrease
- Oil-system efficiency decreases
Oil heat becomes relatively more attractive when those variables move in the opposite direction.
This is why the calculator allows both energy prices and both efficiency assumptions to change.
Cold-Climate Heat Pump Performance Matters in New York
A New York comparison should not use warm-climate heat-pump assumptions without checking low-temperature performance.
Current ENERGY STAR cold-climate criteria require qualifying residential air-source heat pumps to demonstrate:
- COP of at least 1.75 at 5°F
- At least 70% of their 47°F heating capacity at 5°F
- Verification that the required low-temperature performance can be achieved using the system's native controls
These requirements help identify equipment designed for cold conditions, but they do not mean every cold-climate heat pump will have the same annual operating cost.
Before comparing a contractor proposal with oil heat, check the exact model's:
- Heating capacity at 47°F
- Heating capacity at 17°F
- Heating capacity at 5°F
- COP at 5°F
- HSPF2
- Backup-heat design
Seasonal COP Is Not the Same as COP at 5°F
This distinction is important.
The calculator's seasonal COP represents an assumed average relationship between useful heat delivered and electricity consumed across the heating season.
The ENERGY STAR 5°F COP criterion is a specific low-temperature performance test.
They should not be treated as interchangeable numbers.
The calculator's default seasonal COP of 2.7 is therefore an illustrative planning assumption, not an ENERGY STAR national average.
What About Backup Heat?
Some heat-pump installations use supplemental or backup heating during certain conditions.
The effect on operating cost depends on:
- Heat-pump capacity
- Outdoor temperature
- Building heating load
- Controls
- Backup-heat technology
If electric resistance heat runs frequently, electricity consumption can increase materially.
Some homeowners may instead retain an existing oil system as backup in a dual-fuel or partial-load strategy.
The calculator does not separately model backup heat because the correct treatment is highly project-specific.
Heat Pump vs. Oil Furnace: Upfront Cost Is Only Half the Decision
A heat-pump conversion can cost more upfront than replacing an existing oil heating system.
But that comparison can become misleading if another system also needs replacement.
A heat pump provides both heating and cooling.
If a home's central air-conditioning system also needs replacement, the relevant comparison may be:
New Oil Heating System + New AC
versus:
Heat Pump Providing Heating + Cooling.
The calculator therefore includes an optional AC replacement cost on the oil side.
Do Not Add AC Cost If Your Existing AC Is Fine
If the existing air conditioner still has substantial useful life remaining, adding a full AC replacement cost to the oil option would unfairly make the heat pump look cheaper.
The AC field therefore defaults to $0.
Only enter an AC replacement amount when it is genuinely part of the current project.
What About Removing the Oil Tank?
Converting away from oil can create costs that are not included in a basic equipment quote.
Depending on the property and local requirements, a homeowner may need to consider the existing oil tank and associated work.
Do not automatically assume that oil-tank removal is included in a heat-pump quote.
If the project requires additional oil-system retirement work, add that cost when comparing the complete conversion.
What About New York Heat Pump Incentives?
Unlike the expired federal 25C credit, New York continues to have heat-pump programs.
NYSERDA's NYS Clean Heat program currently states that New York State and participating energy companies offer rebates and financing for qualifying heat-pump installations.
For 2026, the program structure varies by utility territory, project type and eligibility.
That means there is no single rebate amount that should automatically be subtracted from every New York heat-pump quote.
The calculator therefore defaults confirmed incentives to $0.
Enter an incentive only after the contractor or program administrator confirms that your specific project qualifies.
Some New York Households May Qualify for Additional Assistance
Income-qualified households may have access to additional electrification assistance through programs such as NYSERDA EmPower+.
Eligibility, project caps and eligible measures vary.
For that reason, CostCandid does not assume an EmPower+ incentive in the standard calculator.
Homeowners who may qualify should check the current NYSERDA rules before accepting a final HVAC quote.
What Happened to the Federal Heat Pump Tax Credit?
This is one of the biggest 2026 updates.
Older articles may still say that qualifying heat pumps receive a federal Section 25C Energy Efficient Home Improvement Credit of up to $2,000.
That information is no longer current for a new 2026 installation.
The IRS states that the Section 25C credit is not allowed for property placed in service after December 31, 2025.
Therefore, a heat pump placed in service in 2026 should not be modeled with the former federal 25C credit.
New York State and utility incentives are separate programs.
Why Some ENERGY STAR Pages Can Still Be Confusing
Consumers may encounter older or not-yet-updated federal-credit language on energy-efficiency pages.
For federal tax treatment, CostCandid uses the current IRS termination guidance rather than assuming an older incentive remains available.
For a 2026 project:
Do not subtract the old 25C credit unless current IRS law applicable to your installation date actually allows it.
When a Heat Pump Can Make More Financial Sense
The heat-pump side generally becomes more attractive when:
- Heating-oil prices are high
- The existing oil system is approaching replacement
- The central AC also needs replacement
- The proposed heat pump has strong cold-weather performance
- The house has a manageable heating load
- Electrical upgrades are limited
- Confirmed New York incentives reduce upfront cost
- The homeowner expects to keep the system for many years
When Keeping Oil Can Still Make Financial Sense
An oil-system replacement can remain competitive when:
- The existing oil infrastructure is usable
- The replacement project is relatively inexpensive
- The central AC still has substantial remaining life
- Heating-oil prices are favorable
- Electricity is particularly expensive
- A heat-pump conversion requires major electrical or building work
- The proposed heat pump would rely heavily on expensive backup heat
Should You Remove Oil Completely or Keep It as Backup?
This does not have to be an all-or-nothing decision.
Some New York homeowners may consider:
- Full heat-pump conversion
- Heat pump with oil retained as backup
- Partial-load heat-pump installation
- Oil replacement while postponing electrification
The correct choice depends on the home's load, equipment condition, available incentives and the homeowner's financial objective.
NYS Clean Heat's 2026 program structure recognizes both full-load and certain partial-load cold-climate heat-pump projects, reinforcing why actual project design matters.
Frequently Asked Questions
Is a heat pump cheaper than oil heat in New York?
It can be, but there is no universal answer. The result depends heavily on heating-oil price, electricity rate, seasonal heat-pump performance, oil-system efficiency and upfront conversion cost.
How much heating oil does an oil furnace use?
It depends on the home's heating demand and system efficiency. In the calculator's illustrative example, a 60-million-BTU useful annual heating load and 85% efficiency require approximately 510 gallons.
Why does this calculator use 138,500 BTU per gallon?
It is the simplified energy-content assumption used to convert required oil-fuel input into gallons for the comparison.
What electricity rate should a New York homeowner use?
Use the effective rate from your own electric bill whenever possible. The calculator's 29.49¢/kWh default reflects EIA's June 2026 New York residential average.
What heating-oil price should I use?
Use a recent delivered price from your supplier. Heating-oil prices can change significantly, so the calculator's $4.00/gallon default is only an illustrative input.
Do heat pumps work during New York winters?
Cold-climate heat pumps are specifically evaluated for low-temperature operation. Current ENERGY STAR cold-climate requirements include a COP of at least 1.75 at 5°F and at least 70% of 47°F heating capacity remaining at 5°F.
Can I still get the federal $2,000 heat-pump tax credit in 2026?
Not for property placed in service after December 31, 2025 under current Section 25C law. Current IRS guidance states that the credit terminates for property placed in service after that date.
Are New York heat-pump rebates still available?
New York continues to operate heat-pump incentive and financing programs, including NYS Clean Heat. Actual incentives depend on utility territory, project design, equipment and eligibility.
Does a heat pump replace air conditioning?
Yes. An air-source heat pump can provide both heating and cooling, which is financially important when an existing AC system also needs replacement.
The Bottom Line
For New York homeowners using heating oil, the heat-pump decision is particularly sensitive to energy prices.
Installation - Confirmed Incentives + Electricity + Maintenance
vs.
Oil Heat
Replacement + Heating Oil + Maintenance + Required AC Replacement
New York has both relatively high electricity prices and meaningful exposure to heating-oil price changes.
That makes generic statements such as “heat pumps always save money” or “oil is always cheaper” especially unhelpful.
Use your actual electric bill, your recent oil delivery price and real contractor quotes.
Those three numbers will tell you far more than a national-average headline.
CostCandid Methodology
This calculator compares the heating-side long-term cost of an air-source heat pump with an oil-fired heating system.
Heating Load ÷ 3,412 ÷ Seasonal COP
Heat Pump Annual Energy Cost
Electricity × Electricity Rate
Oil Fuel Input
Heating Load ÷ Oil-System Efficiency
Heating Oil Gallons
Fuel Input ÷ 138,500 BTU per Gallon
Oil Annual Energy Cost
Gallons × Delivered Oil Price
Long-Term Cost
Net Installed Cost + (Annual Energy + Entered Maintenance) × Years
The default 60-million-BTU annual heating load, seasonal COP of 2.7, 85% oil-system efficiency, installation prices and $4.00/gallon oil price are illustrative assumptions rather than national averages.
The default electricity rate of 29.49¢/kWh uses EIA's June 2026 New York residential average.
For context on heating-oil volatility, EIA reported New York residential heating oil at approximately $5.874/gallon for the week of March 30, 2026. The calculator does not use that volatile weekly figure as its permanent default.
The model excludes backup heat as a separate line item, future energy-price changes, financing, fixed utility charges, oil-tank retirement costs, duct modifications and electrical upgrades unless those costs are incorporated into the user's entered project figures.
