The CB-3500 waste oil heater.

The Clean Burn Model CB-3500 is one of two industrial-grade waste oil burners that we offer. It produces approximately 350,000 BTU/hour. This model is perfect for larger spaces and can be used as a single unit heater or ducted to create a central furnace that heats multiple spaces. The industrial models still maintain the longest cleaning intervals in the industry to make our waste oil furnaces easy to use and maintain.
