The Clean Energy Heating Systems CE-140 Waste Oil Furnace is an entry level waste oil heater that’s perfect for a garage with 1 to 4 bays. With up to 140,000 BTU’s of heating input coupled to our innovative new design, it’s a very cost-effective way to heat smaller spaces.

Best of all, thanks to the CE-140’s ability to turn used motor oil, transmission fluid and other petroleum products into clean, safe heat, this waste oil furnace generates solid ROI while helping the environment.

In addition, all Clean Energy furnaces are engineered from the ground up to burn waste oils and comply with all EPA regulations. They easily install and provide for longer intervals between cleanings, and their low-profile design and flexible configuration is ideal for areas with limited ceiling height and other creative installation requirements.

Best of all, every Clean Energy waste oil furnace is built with our unique, patent-pending stainless steel heat exchanger and flue tubes. This next-generation design ensures long-lasting durability and highly efficient operation for years to come.
