Home heating oil has become progressively cleaner and more efficient over the last few decades by using ultra-low sulfur (ULS) heating oil. ULS heating oil has only 15 parts per million sulfur content which translates into a cleaner burn with fewer deposits on heat exchangers, making for easier maintenance and higher efficiency which is better for the environment and the longevity of heating systems.

The oil heat industry maintains its commitment to protecting the environment while offering customers comfort, convenience, and cost savings.
