Sizing and savings
Square footage is only a starting point. Ceiling height, the number and size of overhead doors, insulation and how much used oil your shop produces all affect which size is right. We'll ask about all four before recommending a unit.
How much you save depends on how much used oil you generate, what you pay for heating fuel now, and how long your heating season runs. Our waste oil savings calculator gives a quick estimate.
