Discover the cost savings and clean energy advantages of switching from heating oil to propane in 2025. Learn why more homeowners are choosing propane for home heat and how Tankfarm makes it easier than ever.
If you're a homeowner still relying on heating oil, it's time to take a closer look at propane. Not only is propane a cleaner, more efficient fuel, but in many real-world scenarios, it's also a more cost-effective way to heat your home. In this post, we’ll break down the real BTU costs, compare efficiency levels, and explore why propane is becoming the go-to choice for modern home heating.
What’s the Real Cost of Heating Oil vs. Propane?
Let’s start with some numbers:
- Heating Oil delivers about 138,500 BTUs per gallon.
- Propane provides around 91,500 BTUs per gallon.
At first glance, it might seem like heating oil gives you more bang for your buck. But that only tells part of the story.
When we factor in efficiency, the comparison shifts.
Useful BTUs per Gallon (Factoring in Efficiency):

Now, let’s factor in costs (example pricing):
- Heating Oil: $4.00/gallon
- Propane: $2.75/gallon
Cost per Million Useful BTUs:

Even at high-efficiency levels, propane is highly competitive. And when oil systems drop below 80% efficiency (as many older furnaces do), propane becomes the cheaper option per useful unit of heat.
The Hidden Costs of Heating Oil
Beyond the price per BTU, heating oil comes with a range of hidden costs that can eat away at your budget and peace of mind. Here’s what many homeowners don’t realize:
1. Higher Maintenance and Repair Costs
Heating oil systems tend to accumulate soot, sludge, and carbon residue. This buildup leads to more frequent cleanings, clogged filters, and inefficient operation. Older systems may require annual or even semi-annual service, adding hundreds of dollars in upkeep every year.
In contrast, propane systems burn cleaner, meaning fewer service calls, longer-lasting components, and a more consistent performance season after season.
2. Oil Tank Replacement and Risk of Leaks
Underground and above-ground oil tanks are prone to corrosion over time. Leaks are not only expensive to clean up but can also cause significant environmental damage. In many areas, homeowners are responsible for the full cost of cleanup, which can range from thousands to tens of thousands of dollars.
Replacing an aging oil tank can cost anywhere from $2,000 to $4,000, not including the cost of disposing of the old tank or restoring the site. Propane tanks, especially when serviced by providers like Tankfarm, are regularly inspected, maintained, and often leased or included in service agreements—reducing the burden on the homeowner.
3. Unpredictable Delivery and Pricing
Many heating oil customers experience surprise bills due to fluctuating oil markets, unclear pricing models, and inconsistent delivery schedules. In winter, this can mean running out of fuel when it matters most—or paying premium rates for emergency fills.
Tankfarm changes the game with smart tank monitoring, automated delivery, and transparent pricing that takes the guesswork out of your energy budget.
4. Environmental and Health Hazards
Heating oil poses a greater environmental threat. A leaking tank can contaminate soil and groundwater. Indoors, soot and combustion byproducts from inefficient oil systems can affect air quality and respiratory health, especially for sensitive individuals.
Propane, on the other hand, is a non-toxic, clean-burning fuel that produces significantly fewer emissions. It burns without soot or ash and contributes to better indoor and outdoor air quality.
Why More Homeowners Are Choosing Propane
Propane isn't just a heat source. It's a whole-home energy solution. Here’s why propane stands out:
1. Clean and Green
Propane emits 30% fewer CO2 emissions than heating oil. It doesn’t leave behind soot or sludge and supports cleaner indoor air.
2. Multi-Use Versatility
Propane is an extremely versatile fuel that you can use propane to power:
- Home heat
- Water heaters
- Cooking appliances
- Clothes dryers
- Fireplaces
- Backup generators
3. Lower Maintenance
Propane systems are clean-burning and typically require less maintenance than oil systems, saving you time and money.
4. Smarter Energy with Tankfarm
Tankfarm takes propane to the next level with:
- Smart tank monitoring
- Transparent pricing
- Easy scheduling and delivery
- No hidden fees
Final Word: Propane Makes Sense in 2025
