Made for waste oil

Using waste oil for fuel presents a unique set of challenges. Our tanks turn those challenges in industry-leading features.

Our accessories

More choices than anyone, for a custom configuration for everyone.

When it comes to waste oil boilers, there really is no other choice than EnergyLogic. Why? Because EnergyLogic is the only manufacturer to engineer a boiler from the ground up for waste oil combustion. On the other hand, the competition just takes traditional designs and then Jerry-rigs them to burn recycled oil. Even worse, you’ll find competitors selling recycled oil boilers that really aren’t even boilers! Whereas EnergyLogic boilers use a true-vessel system, the competition uses a system of heated coils. So why does that matter? With a true-vessel you get heat on-demand, rather than having to wait. Also, an open vessel is expansive and easy-to-access, making maintenance a breeze. Coil systems, by contrast, collect ash between the crevices of their narrow tubing, resulting in rigorous and frequent maintenance that wastes time and money.

EnergyLogic takes pride in the waste oil boilers we produce, but we are especially proud that we are a solutions company. When investing in a used oil boiler system you must have a partner committed to understanding your facility and ready to create a custom configuration suited to your highly individual work environment. Our used oil boilers are already at work in many different industries and facilities, and we frequently partner with car dealerships, heavy equipment services, and transportation companies to heat everything from garages to workshops to office space. EnergyLogic boilers even de-ice parking lots and rooftops. Need hot, potable water? Our boilers can provide hot water to car washes, kitchens, bathrooms and shower facilities, making them the most versatile product of their type on the market.

EnergyLogic is the trusted name in waste oil heating because we have the best combustion, delivered by the American-made Beckett burner. The efficiency of our waste oil burner produces the highest heat-rise, burning away more of the impurities that stay behind in the form of ash. And less ash means EnergyLogic used oil boilers have the industry’s longest maintenance interval. Now that’s comfort with convenience.

EnergyLogic offers the most waste oil accessories of any company so that your waste oil boiler solution is perfectly designed to fit your business and your unique floor-plan. Our boilers are easy to operate and a breeze to maintain. The air compressor silencer allows for extremely quiet operation by reducing the noise of the air compressor. The air compressor silencer is easy to install and fits in a kit with all of the parts you need. EnergyLogic also offers a remote pressure-gauge kit designed to monitor the fuel pump on the waste oil boiler, even if the fuel pump is hard to see. The pressure gauge kit is installed below the preheater to monitor the system pressure and ensure reliable service. When it’s time to clean, our boiler brushes are custom designed to fit our systems and quickly clear ash from the boiler tubes. That way your team wastes less time cleaning and more time being productive in a warm, safe and comfortable environment. That’s what good feels like.
