How Does a Waste Oil Heater Work?

A storage tank on the burner is filled with waste oil from 5 weight to 90 weight, including synthetic. An electric motor operates a circulating fan that pulls air into a blast tube. A pump draws the waste oil from the storage tank and through a filtration system. The filtered waste oil is pumped to the burner system and pre-heated to the perfect temperature for more complete and even combustion.

The pre-heated oil is sprayed into the blast tube where the oil mixes with air. The heated mix of waste oil and air are ignited by a high voltage electric current and is passed over a heat exchanger to remove heat from the ignition. The heat exchanger’s warmth is passed efficiently to cooler air or water passing through the heat exchanger’s other side. All of this heat is vented out to the main space or system to be heated and leftover gas is vented to the outside of the space by a chimney.

above water and sludge, ensuring only used oil is sent to the furnace.

3. Easy spin-on stainless mesh filter.

Flame Retention Head

Patented - This patented design creates a hotter flame than competitor brands for complete

fuel combustion and the highest heat output. Less ash is produced resulting in longer

maintenance intervals than competitor brands.
