Heating Oil vs. Natural Gas vs. Propane

Posted Sunday May 24, 2026

Choosing how to heat your Long Island home? Heating oil, natural gas, and propane each have trade-offs in cost, comfort, and convenience. Here's a straightforward comparison to help you decide.

Heating Oil

Oil burns hot, so many homeowners find oil heat warms a home quickly and comfortably. You buy it as you need it from a local supplier, and modern oil systems are clean and efficient. The main consideration is keeping your tank filled — easily solved with automatic delivery.

Natural Gas

Natural gas is piped in, so there's no tank to monitor. It's convenient where gas lines exist — but many Long Island neighborhoods aren't on the gas main, and converting can be expensive. Prices also fluctuate with the market, just like oil.

Propane

Propane is stored in a tank like oil and works where natural gas isn't available. It tends to cost more per unit of heat than oil, and you're still managing tank levels and deliveries.

Cost to Convert

Switching fuels isn't just about the price per gallon or therm. Converting an oil system to gas can mean running a new gas line, a new boiler or furnace, removing your oil tank, and permits — often thousands of dollars upfront. On Long Island, where many homes aren't on the gas main, those conversion costs can take many years to recoup, if ever. Propane avoids the gas-line issue but you're still buying and storing fuel like oil, usually at a higher cost per unit of heat.

Efficiency and Comfort

Modern oil furnaces and boilers are highly efficient, and because oil produces a lot of heat per gallon, rooms tend to warm up fast. With regular tune-ups and clean fuel, an oil system stays efficient for years. The "hassle" of a tank is largely solved by automatic delivery and monitoring.

Which Is Right for You?

If your home already runs on oil, staying with a reliable local supplier is usually the most cost-effective choice — especially with automatic delivery removing the hassle. Conversion costs to gas or propane often outweigh the savings.
