Since waste oil boilers are similar to and often based on traditional oil boilers, owners can place most models inside the home, generally in a basement or other space designed for heating equipment. However, it is worth considering the logistics of getting the oil to the boiler.
Waste oil comes from many sources, and homeowners who use waste oil heating might have to consider different transportation methods. Some types of oil might not be appropriate for in-home oil tanks, so a waste oil boiler that is easy to access may provide better convenience and safety. Some sources of waste oil might not be reliable. It may also be wise to keep traditional heating oil located on-site as well.
