In reference to ‘Used Oil Heaters’ and ‘Waste Oil Heaters’, the terms ‘Used Oil’ and ‘Waste Oil’ are used interchangeably throughout the industry.

In our experience, ‘Waste Oil’ tends to be the more common term when this type of heater is being referred to ‘in the field’, but sometimes the term ‘Used Oil’ is chosen to show that, though it is waste oil, it is still oil ‘oil’ and is not ‘Waste’ but in fact has a ‘Value’ associated with it.

Aside from a purely ‘marketing’ standpoint, there is no difference between these two terms.
