How Does a Waste Oil Heater Work: Everything You Need to Know

A waste oil heater is a device that efficiently uses reclaimed or used oil as a fuel source to generate heat. It works on a simple principle: the waste oil is first stored in a tank, where it can be filtered and preheated if necessary. This preheated oil is then pumped into a combustion chamber or burner, where it is sprayed as a fine mist. The burner is specially designed to create a controlled flame that produces hot gases. These hot gases then pass through a heat exchanger, which absorbs the heat and transfers it into the surrounding air or a liquid, such as water or antifreeze. The exhaust gases, which are byproducts of the combustion process, are safely vented out through a flue. In this way, waste oil is converted into valuable heat energy, providing a cost-effective and eco-friendly heating option.
