If you heat your home with oil here on Long Island, chances are you’ve heard a few opinions about it. Maybe a coworker mentioned that “nobody uses oil heat anymore.” A relative who switched to gas swore your system was costing you a fortune. Or perhaps your neighbor told you a heat pump would slash your bills overnight. There’s a lot of confident chatter out there – and a lot of it is just plain wrong.
The truth is, heating oil has changed dramatically over the past few decades, and the assumptions floating around at backyard barbecues haven’t caught up. Today’s oil heat is cleaner, more efficient, and in many cases more reliable than the alternatives – especially during a Long Island deep freeze. Let’s walk through the most common heating oil myths and separate the rumors from reality so you can make confident decisions about your home.

Myth #1: Oil Heat Is Outdated
This is probably the most common one we hear. The image many people have of oil heat – a soot-streaked basement furnace from 1972 – has very little to do with the systems running in homes today. Modern oil-fired boilers and furnaces are precision-engineered, efficient, and quiet.
In fact, modern oil systems can hit AFUE (Annual Fuel Utilization Efficiency) ratings of 85% to 95% – comparable to high-end gas systems. They burn fuel more completely, produce far less particulate, and many use sealed combustion chambers that draw outside air for cleaner, safer operation.
Why This Myth Persists
So, is heating oil outdated? Not even close. The technology has quietly evolved alongside other heating systems – it just hasn’t gotten the same marketing budget. Long Island in particular has a strong oil heat infrastructure because it works well for our climate, our older housing stock, and our occasional brutal cold snaps.
Myth #2: Heating Oil Is Less Efficient Than Natural Gas
When people compare oil heat vs gas heat, efficiency is usually the first thing they bring up. The assumption is that gas just burns “cleaner and better.” But this is one of the most misleading heating oil myths out there.
Heating oil actually contains roughly 138,500 BTUs per gallon, compared to about 100,000 BTUs per therm of natural gas. In plain English, this means a single gallon of oil packs significantly more heat energy than the equivalent unit of natural gas. So, when you ask, is heating oil less efficient than natural gas? – the honest answer is no, not when you measure what actually matters: how warm your house gets per dollar spent.
That doesn’t mean gas is a bad choice – it works well for many homes. But the idea that oil is somehow a downgrade in efficiency is simply not true. Oil heat vs natural gas comes down to the price of fuel, the cost to convert your system, and what infrastructure already runs to your house. For many Long Island homeowners, oil remains the more practical and affordable option year after year.
Why This Myth Persists
A lot of the “gas is more efficient” talk comes from old comparisons that pitted modern gas furnaces against decades-old oil units. When you compare modern to modern, the gap closes – and in some metrics, oil pulls ahead.
Myth #3: Heat Pumps Will Always Save You Money
Electric heat pumps are having a moment, and they’re a great fit for some homes – particularly newer, well-insulated ones in milder climates. But the claim that they automatically beat oil on cost and comfort is one of the heating oil myths that needs more honest discussion.
Here’s the issue: traditional air-source heat pumps lose efficiency as the outdoor temperature drops. When Long Island sees a string of 15-degree nights, a heat pump has to work much harder, and many models switch over to auxiliary electric resistance heat, which is significantly more expensive to run.
Cold-climate heat pumps are improving, no question. But the all-or-nothing pitch that you should rip out your oil system and replace it with electric ignores upfront installation costs (often $15,000 to $30,000), the realities of older Long Island homes, and the fact that your electric bill will jump considerably in the dead of winter.
Why This Myth Persists
So, is heating oil less efficient than electric? On a 50-degree fall morning… maybe. On a 12-degree January night with a stiff wind off the Sound, oil heat is often the more efficient – and much more comfortable – choice. The oil heat vs electric heat pump conversation deserves more nuance than the marketing usually allows.
Myth #4: Modern Heating Oil Is Dirty
Most heating oil delivered on Long Island today is ultra-low sulfur heating oil (ULSHO), and many suppliers – including us – offer Bioheat® blends that mix petroleum heating oil with renewable biofuels made from things like soybean oil and recycled cooking oil. Bioheat blends can dramatically reduce greenhouse gas emissions compared to traditional heating oil, and they burn so cleanly that many systems can go longer between service appointments.
Why This Myth Persists
This myth has real staying power because it has a kernel of historical truth. Decades ago, oil heat did produce more soot and emissions than it does today. But the fuel itself has changed.
Modern heating oil systems also include better combustion controls, sealed chambers, and digital ignition, so the actual burn is far more efficient and produces far less of what people picture when they hear “oil furnace.”
Myth #5: Heating Oil Is Always More Expensive
People love to compare fuel prices on a single day in October and declare a winner. But the real cost picture for any heating fuel (oil, gas, propane, or electric) depends on a lot of moving parts: the price per unit, system efficiency, conversion costs, maintenance, and your home’s insulation.
Long Island homeowners who have already invested thousands into a quality oil system rarely come out ahead by switching fuel types. Once you factor in conversion costs, new equipment, possibly new lines run to your home, permits, and the time your home is torn up, the “savings” often disappear into a 10- to 15-year payback window.
Why This Myth Persists
There’s something worth saying plainly: oil prices fluctuate. But so do natural gas prices and electric rates – especially in the Northeast, where electric supply costs have risen sharply in recent years. There’s no fuel that’s permanently cheap. What there is, though, is a fuel system you already own and a service relationship you can rely on.

Myth #6: You’re Locked In With One Oil Supplier
This one might be the most damaging myth of all because it convinces homeowners they have no choice. The truth: you are never locked into a single oil supplier. You’re free to comparison shop, switch providers, or move to a Cash on Delivery (COD) arrangement that gives you maximum flexibility on pricing.
That’s actually the entire reason Express COD exists. We deliver heating oil to Long Island homes without long contracts, hidden fees, or pressure to “lock into a plan.” You order when you want, you pay the price quoted that day, and you stay in control of your own home.
Myth #7: All Oil Tanks Are Risky and Outdated
Older steel tanks did have a finite lifespan, and the horror stories about leaks aren’t entirely made up – but they describe a different generation of equipment. Modern oil tanks, especially the double-walled and corrosion-resistant models installed today, are built for decades of safe service when properly maintained.
Routine inspections, tank monitoring, and timely replacement of older equipment make oil heat as safe as any other home heating system. If you have an older tank and you’re worried about it, the right move isn’t to abandon oil – it’s to talk with your service provider about a tank assessment.
What Modern Heating Oil Systems Actually Look Like
Here’s what people often don’t realize about modern heating oil systems:
- They run quietly and efficiently, with high-efficiency burners and sealed combustion.
- They can use cleaner burning Bioheat blends with lower emissions.
- They produce strong, consistent heat even on the coldest Long Island nights.
- They’re serviced by experienced local technicians who know the systems inside and out.
That last point matters more than people give it credit for. When a heat pump fails in February, you may be waiting days for a part. When an oil burner needs a tune-up, your local oil company can often be at your door the same day. That’s a real comfort difference.
Is Heating Oil Efficient? The Honest Answer
Yes. Modern heating oil is efficient, increasingly clean, and well-suited to the realities of heating an older home through a Long Island winter. The fuel carries more energy per unit than natural gas, modern systems burn it more completely than ever before, and Bioheat blends keep pushing the environmental footprint down further.
The “oil heat is outdated” narrative makes for a tidy headline, but it doesn’t match what’s actually happening in the boiler rooms and basements of Nassau and Suffolk counties.
A Local Note: Why Long Island Still Runs on Oil
Long Island’s housing stock is a big part of the story. We have a lot of older homes – beautifully built but designed before central natural gas distribution became common in many areas. Running new gas lines to neighborhoods that have been on oil for 60 or 70 years is expensive and slow.
Meanwhile, the oil delivery network here is mature, competitive, and built around the seasons we actually live through. That’s why so many homeowners – even those who’ve poked around the alternatives – end up sticking with oil. It works.
