Better for your house.

Our Guardiant Premium Bioheat is blended with high-performance fuel conditioners to protect your storage tank, keep your heating oil clean and stable, and improve the overall health, efficiency, and lifespan of your heating system.

And your home.

Clean-burning Bioheat Fuel is renewable, biodegradeable, and extremely efficient, boasting the highest BTU content of any alternative fuel.

A new day has dawned.

With higher blends of ultra-low sulfur Bioheat Fuel approved for use in today’s high-efficiency heating equipment, the heating oil industry now has a more environmentally friendly, renewable, and less carbon-intensive product than natural gas.


Tank Goodness.

At 700,000 gallons, we have the most on-site storage of any heating oil dealer in the area. This means that if there’s a sudden threat to oil supply due to a natural event, an embargo, or a breakdown in the supply chain, our trucks stay filled and our customers stay warm.


Breathe easy. Rest assured.

Guardiant Premium Bioheat Fuel improves air quality in your home and neighborhood by significantly reducing greenhouse gas emissions and particulate matter in your heating systems.


The right call.

Non-toxic, non-carcinogenic, and non-explosive, Horan’s clean green heating oil is as safe is at gets. If you dropped a match in our product, the flame would go out as if dropped into water.

Sparing no expense to reduce your costs

Some ask how it’s possible that we can provide greater cost savings than our competitors when we don’t offer the same bottom-of-the-barrel prices. It’s true – because we invest heavily in enhancing the performance and efficiency of the product we put into our customers’ homes, our Guardiant Premium Bioheat Fuel tends to cost slightly more up front. However, not only is our product far cleaner and healthier for your heating system, resulting in fewer maintenance issues and “no heat” calls, it’s also far more efficient, meaning you’ll require much less of it over time. This makes our product less expensive annually than the cheaper, generic alternative being marketed to consumers as a cost saver. Can a discount fuel dealer prove that they’re reducing your heating costs? Because we can, and we regularly do so for those who entrust us with their business.

Maria S.

I’ve been using Horan oil for 15 years (since I bought my house). I have never had a problem that wasn’t resolved, question that wasn’t answered, or compliment that was not truly deserving. The office staff is so easy to deal with and it extends all the way through to the techs. Everyone is so knowledgeable and friendly! They may not be the cheapest but I’m a firm believer that you absolutely get what you pay for with Horan Oil!

Horan Oil is the best! Came home from a ski trip late at night to an ice-cold home. Called Horan Oil, and received a return call right away and shortly thereafter George appeared at our door. Like a savior in the night, he was friendly, efficient, and he gave us HEAT! The next week, we looked out the window after the big snow storm to see one of Horan Oil’s delivery men trekking up through the snow with a big hose to get us our oil. So grateful for what they do for our family!
