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.

Waste Oil Heaters Key Features

Key Feature Waste Oil Heater
Stanless Steel Heat Exchanger

Exclusive - Designed to prevent corrosion, warping, and weld breakage.

Built to last decades, not years. Open design for easy cleaning. 

Digital Hour Meter

Tracks runtime

Accutemp Preheater

Patented - Rapidly heats the widest range of viscosities of used oil,

synthetic oils, and other acceptable fuels.

Integrated Air Compressor

Built-in so you don’t have to connect to and rely on shop air.

Providing 24/7 heating availability.

Side Suction Metering
Fuel Pump

Patented - Reliable, consistent fuel delivery regardless of fuel type

(up to 90W) with no manual adjustments.

Low Fuel Cut Off

Exclusive -

*Included with fuel delivery kits, complete systems, and with heater only.

Elevated Fuel Pick Up

Exclusive

1. Pump can be mounted at the fuel source—instead of on top of the tank

—so the pump is flooded with used oil, not air!

2. Fuel pick-up is six inches above the bottom of the tank,

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.

Swing Away Burner

This convenient combination makes cleaning the chamber faster

and easier than any other brand. One tool, 30 minutes or less.

Fuel Guage

Visual indicator of how much used oil is in your tank.

Drain Valve

Makes it simple to purge water or other contaminants

that naturally settle in the bottom of the tank.
