Oil vs Gas Boilers: What’s Better for Homes?

oil vs gas boiler
July 25, 2025

When Southampton, Easthampton, Shirley, or Quogue see winter, there is one thing that every homeowner relies on: consistent heat. And for a lot of houses in Suffolk County, that heat originates from a boiler system. But when the moment arrives to replace or install a new boiler, the decision-maker is, should you use oil or gas?

At Paradise Plumbing, we have installed, fixed, and serviced boilers on Long Island for decades. So, let’s explore the pros and cons of oil versus gas boilers. We will also assist you in making an informed decision about what’s best for your home.

Understanding How Boilers Work

Let’s first summarize what a boiler is. A boiler does not employ a furnace with forced air, but rather it heats water and either distributes it through radiators, baseboard heaters, or a radiant floor system. The water is heated by either oil or natural gas as a fuel source.

Oil and gas boilers both accomplish the same task: heating your house. What varies is the way they work, expense to operate, installation, upkeep, and earth-friendliness.

Oil Boilers

Advantages

Disadvantages

Perfect for Houses Without Gas Lines More Expensive Fuel
Greater British Thermal Units per Gallon You Need to Arrange Deliveries
Longer Lifespan of Equipment (usually 15–25 years) More Maintenance
Safe Storage

Oil boilers are a reliable heating option, especially for Suffolk County homes that aren’t connected to a natural gas line. These systems use a storage tank of heating oil to generate steady, powerful heat. So, they are perfect for our cold Long Island winters. Here are the advantages and disadvantages of oil boilers that you need to consider.

Gas Boilers

Advantages

Disadvantages

Lower Operating Costs Not Provided Everywhere
Cleaner Burn Briefly Shorter Lifespan
No Need for Deliveries Explosion Hazard (Though Low)
Compatible with Modern Smart Systems

Gas boilers are a top choice for homeowners looking for efficiency, convenience, and lower heating bills. These systems eliminate the need for fuel deliveries because they are powered by a direct connection to the municipal gas supply.

Installation Costs: Oil vs. Gas

Installation costs differ based on system size, manufacturer, and infrastructure, but here’s an estimate:

System Type  Average Install Cost
Oil Boiler $5,000 – $10,000
Gas Boiler $4,000 – $9,000

Gas boilers are slightly more expensive to install if your house is not already plumbed into the gas line. Otherwise, running a new pipe might make oil more economical initially.

Environmental Impact

If environmental considerations are important to you, natural gas gets the eco-points. It produces:

  • 25% less CO2 than oil
  • Less particulates and pollutants

Aside from this, oil boilers can be cleaned up with biofuel mixes, and maintenance assures efficiency regardless of the system.

What About Dual-Fuel or Hybrid Systems?

If you’re undecided or reside in a borderline zone of gas supply, a dual fuel system may be for you. Dual-fuel systems have oil as their main source but shift to electric backup when it’s necessary. They’re inexpensive and efficient—but they’re less standard and harder to install.

Inquire at Paradise Plumbing if your residence is eligible.

What Do We Recommend?

Here’s our Suffolk County local, straightforward take from working statewide:

  • Live out in the sticks without gas pipes? → Opt for oil but be sure to get regular maintenance.
  • Hooked up to a gas pipe? → Opt for gas for cheaper bills, cleaner running, and less trouble.
  • Worried about initial expense? → Oil might be short-term champion, but gas is a long-term winner.
  • Expecting to resell in a few years? → Gas boilers provide higher resale value in today’s eco-friendly marketplace.
