The Science Behind Bioheat—Why Your Heating Oil Just Got Cleaner

Thu, 04 Dec 2025 10:52:51 GMT

How biodiesel blends are transforming home heating without touching your equipment.

Your heating system doesn't know the difference. That's the beauty of Bioheat—and the secret that's quietly reshaping how New England heats. When Tasse Crowley Energy delivers B5, B10, or B20 Bioheat to your tank, you're getting heating oil blended with biodiesel, a renewable fuel made from agricultural byproducts like soybean oil, animal fats, and recycled cooking oil. No equipment modification. No disruption. Just cleaner combustion from day one.

What makes biofuel different from traditional heating oil? The source. Traditional heating oil comes from crude extracted from underground reserves—carbon that's been sequestered for millions of years. When you burn it, all of that carbon releases into the atmosphere where it stays for decades. Biodiesel, conversely, comes from plants and organic waste. The carbon released when you burn it was absorbed from the atmosphere during the plant's growth cycle, creating a closed-loop carbon system.

Testing by the National Oilheat Research Alliance (NORA) documented that a B20 blend (20% biodiesel, 80% heating oil) reduces sulfur oxide emissions by as much as 80% or more, nitrogen oxide emissions by about 20%, and carbon dioxide emissions by approximately 15%. For a typical home in Maine, that difference means cleaner combustion, less soot buildup inside your furnace, and fewer contaminants entering your home's air.

The Northeast heating oil industry has already achieved a nearly 26% reduction in greenhouse gas emissions since 2008—surpassing its original 15% target by 2023—primarily through increased biofuel adoption and efficiency improvements. That momentum will accelerate: New York has mandated minimum biodiesel blending of 5% today, rising to 10% in 2025 and 20% by 2030.

Why this matters to your budget: Bioheat has the highest BTU content of any alternative fuel, meaning you get more heat per gallon. Cleaner combustion also means less maintenance and longer equipment life—a tangible financial benefit that offsets the small per-gallon premium.

By choosing Bioheat® fuel, you’re making a choice that’s both good for you and the environment. Let’s continue working together towards a greener future.

Cut Your Oil-Heat Bill This Winter

Tasse Crowley Energy helps homeowners get more comfort out of every gallon of heating oil. The steps below focus on tightening up the house, tuning up equipment, and using smarter controls so you spend less to stay warm.

1. Schedule an annual system tune-up

A professional cleaning and tune-up helps your boiler or furnace burn fuel more efficiently and can reduce unnecessary fuel use over the season. The technician can also spot issues early, lowering the risk of mid-winter breakdowns and expensive emergency calls. [functions.fetch_url]

2. Enroll in a budget plan with automatic delivery

Level monthly payments spread your annual heating cost over 12 months, instead of concentrating large bills in the coldest months. When paired with automatic delivery, you avoid run-outs and the stress of constantly checking your tank.

3. Use a programmable or smart thermostat

A properly set thermostat can lower fuel use by turning the temperature down when you are asleep or away and bringing it back up before you need it. Smart thermostats add app control and learning features, helping you avoid heating an empty house.

4. Seal air leaks and improve insulation

Air gaps around windows, doors, and sill plates let heated air escape and cold air creep in, forcing your system to run longer. Simple air sealing with caulk and weatherstripping, plus upgraded insulation in attics and basements, can meaningfully cut heat loss. [functions.fetch_url]

5. Consider upgrading older heating equipment

If your boiler or furnace is 20+ years old, a modern, high-efficiency system can often deliver substantial fuel savings compared with legacy units. Newer equipment also tends to offer quieter operation and better comfort control.

6. Take advantage of automatic heating oil delivery

Automatic delivery uses your historical use and current weather to time deliveries before your tank runs low. This helps you avoid emergency deliveries, protects the system from running dry, and simplifies planning for the season.

7. Ask about cleaner, low-sulfur or bio-based fuels

Where available, ultra-low sulfur heating oil or blends that include renewable biofuels can reduce emissions while working seamlessly in most oil-heat systems. These fuels support a smaller environmental footprint without sacrificing comfort.

8. Improve window performance

Storm windows, interior window panels, or clear insulating film can reduce drafts and heat loss through older windows. These low-disruption upgrades are often more cost-effective than full window replacement if your frames are still sound.

9. Insulate hot water and heating pipes

Uninsulated pipes running through unheated spaces shed valuable heat before it reaches living areas. Adding pipe insulation is a quick project that helps your system deliver more usable warmth to your rooms.

10. Use the sun strategically

On sunny days, open south-facing curtains or blinds to let in solar heat. After sunset, close window coverings to add a layer of protection between warm indoor air and cold glass surfaces.

11. Control exhaust paths and unused spaces

Open fireplace dampers, bath fans, and kitchen vents can pull warm air out of your house if left running or open unnecessarily. Closing dampers and doors to unused rooms helps keep conditioned air where your family spends time.

12. Keep vents and radiators unobstructed

Furniture, rugs, and heavy drapes placed in front of radiators or supply vents block heat from circulating freely. Keeping these areas clear helps rooms warm more evenly and may allow you to stay comfortable at a slightly lower thermostat setting.

13. Dial in your thermostat settings

Even small changes in temperature settings can reduce fuel use over the season. Many households find they can stay comfortable by lowering the setting a couple of degrees during the day and a bit more at night when using appropriate bedding.

14. Partner with a local heating expert

Working with a local provider like Tasse Crowley Energy gives you access to technicians who know regional housing stock, weather patterns, and fuel options. That local insight makes it easier to design a plan that balances comfort, cost, and environmental impact for your specific home.
