All flames are not combusted equal. The EnergyLogic burner produces a flame that's twice as hot as our nearest competitor. How do we make our fire even hotter? By getting more energy out of whatever fuel you use. Our Accutemp preheater heats the widest range of viscosities of waste oils, synthetics and other fuels which allows our burner to generate the most efficient, cleanest-burning flame. Simply put, EnergyLogic gets air hotter faster. A hotter flame also produces less ash. That means less maintenance. So you can quit messing with the heater and get back to work.
