Over the years, oil heat has become more environmentally friendly thanks to advancements like high-efficiency heating technology and Bioheat. Now, oil heat consumers can feel even better about choosing heating oil!

All About ULS Heating Oil

Massachusetts is transitioning to a new and improved heating oil. Appropriately named Ultra-Low Sulfur heating oil, or ULS heating oil, the upgraded fuel has many unique benefits that will contribute to cleaner air and cost savings for all of our customers. Here’s how:

  • ULS heating oil has only 15 parts per million (PPM) sulfur, compared to the 3,000 PPM contained in traditional heating oil. This means that ULS heating oil contains 99% less sulfur than regular oil, producing significantly fewer emissions into the air.
  • ULS heating oil produces 40 times less soot and 90% less ash buildup[1], compared to traditional heating oil. A cleaner burn means cleaner heating equipment! While oil heat customers will still need to schedule annual tune-ups, less soot and ash build up will help your equipment last longer.
  • ULS heating oil produces 99% fewer sulfur dioxide emissions and 30% fewer nitrogen oxide emissions[2], resulting in a safer air for us to breathe. The clean air starts benefiting you in your home, and adds up throughout the state to contribute more positively to the environment.
  • ULS heating oil is compatible with existing oil heat equipment. You won’t have to install a new system to use ULS heating oil. It works seamlessly with current oil heat systems.
