Summary:
Long Island winters are genuinely cold, with average January lows of 24°F and February lows of 25°F, plus daily temperatures often staying below 40°F with cold winds. This climate reality shapes which heating fuel works best.
Heating oil provides the fastest way to heat up your home, delivering high energy potential with quick heat once your furnace starts. Oil burns hotter than natural gas, providing more heat output—ideal for very cold climates like ours. When that February storm hits and temperatures plummet, you’ll notice the difference in how quickly your home reaches comfortable temperatures.
The BTU numbers tell the real story about heating power. Propane delivers 91,500 BTUs per gallon, requiring 1.52 gallons to equal the heat content of one gallon of oil. Natural gas provides 1,030 BTUs per cubic foot, needing 135 cubic feet to match one gallon of heating oil.
This energy density advantage means your heating oil furnace doesn’t have to work as hard or run as long to maintain your desired temperature. Heating oil provides more heat than natural gas, which proves especially valuable during extremely cold weather.
During Long Island’s coldest days, when your heating system faces its biggest challenge, oil’s superior heat output becomes a practical advantage. Your furnace cycles less frequently, potentially extending equipment life while keeping your home consistently warm. This efficiency becomes particularly noticeable in larger homes or those with older insulation, where every BTU counts toward maintaining comfort.
The energy density also affects storage efficiency. Your oil tank holds more potential heat per gallon than propane tanks of similar size, meaning fewer deliveries and more heating capacity on your property when you need it most.
Safety concerns often influence heating fuel decisions, and heating oil offers several built-in advantages. Unlike natural gas, heating oil is a liquid that won’t create suffocation hazards from leakage, doesn’t vaporize at room temperature, and releases no dangerous gas.
Heating oil is not explosive, gets stored in tanks under no pressure making tank blasts impossible, and the burner only takes the small amount the combustion chamber requires during operation. This means you’re not dealing with pressurized gas lines or explosive vapor risks.
Your oil storage tank, whether located underground or outdoors, provides a secure fuel supply without the infrastructure dependencies of natural gas lines. With heating oil, you’re not dependent on gas supply lines—you control your fuel levels and never worry about gas shortages or interruptions.
This independence proves valuable during severe weather events or utility emergencies. While gas service might get interrupted during storms or infrastructure problems, your oil tank maintains your home’s heating capability. Heating oil can always be delivered by trucks suited for all weather conditions, ensuring supply continuity even when other utilities face challenges.
The storage aspect also provides budgeting flexibility. You can choose when to fill your tank based on price fluctuations or seasonal patterns, rather than being locked into whatever rate the gas utility charges during peak demand periods.
While heating oil typically costs more than natural gas or electricity for heating, the complete cost picture includes factors beyond just fuel prices. Heating oil operates in a highly competitive market where prices vary daily among suppliers, and comparison websites help you find the lowest current prices.
Current propane prices around $2.90 per gallon make heating oil the more cost-effective option when you factor in energy content differences. The key is understanding total heating costs, not just per-gallon pricing.
Since the beginning of 2025, heating oil prices increased 6.15% reaching an average of $2.45 per gallon due to rising global consumption and declining distillate inventories. However, heating oil prices are projected to average $3.50/gallon in winter 2025, representing a 9% decline from 2024.
The EIA expects heating oil prices to remain steady or slightly lower compared to last season due to recent crude oil price declines and healthier inventory levels than last winter. This stabilization comes from increased refinery output and global crude price moderation.
Long Island’s heating oil market benefits from competitive dynamics that natural gas monopolies can’t match. With electricity or natural gas, you’re bound to purchase energy from a single supplier creating a monopoly where prices are often dictated. Oil customers can shop daily for the best prices among multiple suppliers.
Heating oil companies offer various pricing plans including fixed pricing where the price per gallon remains constant throughout the contract, or cap pricing ensuring you won’t pay more than a certain amount even if market prices increase. This flexibility helps with budget planning in ways that utility-controlled pricing cannot.
The ability to time your purchases strategically—buying more when prices drop or less when they spike—provides cost management options unavailable with piped gas utilities that bill you monthly regardless of market conditions.
Installation costs vary significantly between heating systems, with propane systems often having lower upfront costs due to simpler design and fewer components, while oil heating systems may require more extensive installation including storage tank placement and additional safety measures.
However, conversion costs tell a different story. If you already have an oil furnace, switching to natural gas requires major upfront investment, while building new or having existing gas line access makes natural gas installation potentially smart. Natural gas isn’t available in all areas, and gas line installation can be expensive.
Properly maintained heating oil systems are cheaper than gas or electricity-fired systems and last much longer—typically 10-20 years depending on consumption and maintenance, though they require somewhat greater care. This longevity factor affects your total cost of ownership significantly.
Equipment replacement timing also differs between fuel types. Oil furnaces and boilers tend to have longer service lives when properly maintained, while gas equipment may need replacement sooner. The durability advantage of oil equipment can offset higher fuel costs over the system’s lifetime.
The Consumer Energy Council of America calls fuel conversion an “expensive gamble” and recommends homeowners upgrade their oil equipment to achieve conservation rather than switch fuels. This guidance suggests that optimizing your current oil system often provides better value than converting to different fuel types.
For Long Island homeowners, the infrastructure reality matters too. Many areas have established oil delivery networks but limited natural gas availability, making oil the practical choice regardless of theoretical cost comparisons.
Heating oil remains the most practical and cost-effective option for most homeowners in Long Island, especially when you consider our climate, infrastructure, and market dynamics together. Homes in colder climates benefit from the higher heat output of heating oil, while those looking to cut energy bills might prefer natural gas efficiency.
Your decision ultimately depends on your specific situation: existing equipment, home location, budget priorities, and heating needs. Even with new energy options rising, heating oil isn’t going anywhere—especially here in Long Island. For reliable winter heating with fuel supply control and competitive pricing options, many Nassau and Suffolk County homeowners continue choosing heating oil.
