Did you know that versatile propane gas comes from the same source as our clean burning home heating oil? That's right, propane is produced from both natural gas processing and crude oil refining in roughly equal amounts. It is nontoxic, colorless and virtually odorless. But most importantly, it's the safest form of gas available. Propane can be used for your primary heat source, space heating, clothes drying, cooking, water heating, grilling and in fireplace inserts.
