Why Choose Bioheat® Fuel?

Densmore Oil Company provides Bioheat® fuel containing ultra-low sulfur heating oil (ULSHO) with a maximum 15ppm sulfur content. We’re proud to offer Bioheat Plus® fuel blended with ULSHO to our customers in Southeastern Connecticut and Southwestern Rhode Island because of its many environmental and money-saving benefits, including:

  • Lower-carbon fuel use at your property
  • Lower carbon emissions
  • Lower sulfur content reduces sooting and scaling, which prolongs the heating system lifespan and causes no problem to your oil heating equipment or tanks
  • Increased heating system efficiency, helping you save more annually on fuel usage
  • ULSHO produces fewer emissions compared to heating oil with higher sulfur content, which will help to reduce sulfur dioxide by 2% because we blend ULSHO with biodiesel. This means you can add an additional 5–10% to these numbers!

When ULSHO is blended with a minimum of 2% biodiesel, it has a lower greenhouse gas emission than natural gas. Densmore strives to go above and beyond by blending 20% biodiesel into our ULSHO, creating B20 Bioheat Plus® fuel for you.


Bioheat® Fuel vs. Natural Gas

As energy options continue to diversify in New England, we’d like to remind our oil customers why we still highly recommend Bioheat® fuel as a sustainable home energy option.

Home Safety

Bioheat® fuel is nonexplosive, so you can rest easy each winter knowing that you are heating your home with a safe, reliable, and efficient fuel provided by a local company you can trust. Additionally, Densmore provides annual heating system tune-ups to ensure your equipment is operating safely and efficiently.

Environmental Advances

The Bioheat® fuel industry has cut its total greenhouse gas emissions by approximately 33% over the last four decades. Conversely, natural gas leaks in the US produce 28 million tons of methane each year, which is a greenhouse gas about 30 times more potent than carbon dioxide.

Financial Savings

Converting to natural gas or electric can cost more than $20,000 in parts and labor, while upgrading your current boiler or furnace can save you up to 30% on your annual fuel bills. You can save an additional 10% each heating season simply by having annual maintenance performed.

Overall Value

As a Bioheat® fuel customer, you can choose which local company delivers your fuel and services your equipment. Unlike major utilities, Densmore is available to assist you at any time and in any weather condition.
