DIY waste-oil burners can be ineffective and harmful to the environment. However, advancements in technology have made modern, professionally built waste-oil heaters very environmentally friendly. Today’s waste-oil heaters are capable of completely combusting used oil. This process minimizes exhaust gasses to levels similar to a single Diesel truck for a clean burn. Moreover, burning used oil for heat replaces the need for other fuel-energy sources such as natural gas, propane, and electricity. When you add these factors together, using a waste oil burner greatly benefits the environment.
