(1) Accutemp PreheaterUsed oil must be preheated prior to combustion. Our patented preheater rapidly heats the blended viscosities of crankcase oil, synthetic oil and other acceptable fuels to a precise temperature so your waste oil burner ignites successfully. Incorporating our high output low amp draw PTC technology combined in a large volume aluminum housing means we can heat the coldest oil and have a reserve preheated and ready to go. Annual cleaning is as fast and simple as it gets. | ![]() |
![]() | (2) Integrated Air CompressorAll of our waste oil heaters come with a built-in air compressor. That means you don’t have to worry about installing additional airlines, having the capacity to run your tools and used oil heater at the same time, have the compressor available 24/7 to run your heater and, finally, no worries about having wet shop air enter your waste oil burner and creating light-off issues. Our small but powerful air compressor is built to last and is field serviceable. |
(3) Flame Retention HeadBy holding the flame stable, our patented flame retention head creates a hotter flame for complete fuel combustion. What does that mean? Less ash, longer maintenance intervals and higher heat output from your waste oil heater. If you already have a waste oil heater, look at the ash. If it is fine and white like baby powder you have good combustion. If it’s grey, brown or oily, you have poor combustion and it is working a lot harder than it should to heat your building. | ![]() |
![]() | (4) Swing Away BurnerPull the quick disconnect plug for the preheater, undo a few nuts and our waste oil burner door simply swings open to give you easy access to the entire stainless steel heat exchanger for quick maintenance and easy cleaning. It’s an easy-access, easy to clean waste oil heater. |
(5) Stainless Steel Heat ExchangerMade of special stainless steel alloys, our heat exchanger is lighter, more durable and more corrosion resistant than the competition, and it has a longer life. It also heats up faster, allowing for continuous use at nearly twice the temperature of most models. Last but not least, its streamline design makes cleaning easy and fast. We are the only company that uses stainless steel in all of their heat exchangers and after 25 years, we have proven they will outlast other alloys. | ![]() |
![]() | (6) Squirrel Cage BlowerOur squirrel cage blower is much quieter than traditional axial fans. It also outlasts cheaper axial fans and can effectively re-circulate the air in your shop from wall to wall. It’s easy to clean and maintain like all of our waste oil heater components. |
(7) Easy Access Cleaning CapThe cleaning cap is released by removing two screws. Any ash in the stainless steel heat exchanger can be pushed to this point where it is typically gathered in a plastic garbage bag and can be disposed of with normal trash. These waste oil heating systems require no vacuuming, no climbing halfway in the heating chamber and you can count your cleaning time–typically once a year–in minutes, not hours. | ![]() |
![]() | (8) Adjustable LouversAll of our waste oil heater come with standard louvers that direct the air up or down. They can be moved to the opposite side of the cabinet or a second set can be added so hot air comes out both sides of the used oil heater. Our adjustable louvers can be added to the existing set of louvers to allow air to be directed side to side, in addition to up and down. |
(9) Steadyflo Metering Fuel PumpOur Steadyflo metering fuel pump delivers the precise volume of fuel to the waste oil burner regardless of viscosity. There are no adjustments ever required as the patented gear set always measures and delivers the correct amount of fuel to the used oil burner. That’s why we can reliably burn from 5 to 90 weight oil and pump your used oil fuel anywhere in your facility. | ![]() |
![]() | (10) Low-Fuel CutoffAvoid frustration and downtime when this safeguard alerts your waste oil heater to turn off when oil is low. |
(11) Fuel GaugeDesigned for convenience and easy visibility, our used oil storage tank gauge lets you see exactly how much used oil is left in your tank. By allowing you to prepare ahead of time, it helps you avoid the hassle and time of re-priming an empty tank | ![]() |
![]() | (12) Drain ValveThe drain valve makes it simple to empty the used oil storage tank of liquids such as water and antifreeze that naturally separate beneath the used oil. |
(13) Spin-on Waste Oil FilterOur spin-on filters keep your system running stronger, longer. Made of stainless steel mesh to meet the demands of used oil filtration, they last far longer than any others and — unlike reusable filters that are messy and difficult to clean — are simple and easy to maintain. | ![]() |

Waste Oil Heater Tanks
Make your EnergyLogic waste oil heater even more effective with our innovative tank configurations.
Tanks
Everything about our used oil storage tanks is designed specifically for used oil, which means they’re engineered to support waste oil heating. For example, our tanks are the only ones with fuel pick up six inches from the base. Because oil rises to the top, this guarantees that your fuel line will never pick up the wrong liquid (such as water or antifreeze). Also, the tanks’ low drains make it easy to eliminate naturally separated liquids. Our used oil storage tanks also include a low-fuel cut off the keeps the heater from calling for fuel when the tank is empty. The result? Your heater doesn’t lose prime and you don’t have to deal with the associated nuisances.
500 Gallon Used Oil Storage Tank
When you need to store large amounts of fuel, this is the tank for the job. Our 500 gallon tank offers all the durability of our other models on a bigger scale. It also comes with a double wall.
Emergency Vent Cap
Required by local codes in some states, this safety feature helps keep your tank from reacting in case of a fire. Should high heat cause the oil in your tank to expand, this cap allows air to escape from the tank and relieve that pressure instead of exploding. It fits all tanks 250 gallons and larger and complies with local codes and regulations.
Waste Oil Heater Parts & Accessories
Make your EnergyLogic waste oil heater even more effective with a few well-designed accessories.
Air Delivery: Multi-Directional Louvers
When the up-and-down air distribution from our standard louvers isn’t targeted enough, our multi-directional louvers allow you to move the air side-to-side. Working together, our standard and multi-directional louvers create very targeted air distribution so you can locate your heater where it’s most convenient and know your shop will stay warm. They can be installed on both sides of a unit to direct air in multiple directions.
Air Delivery: Standard Louvers
Standard louvers offer more installation flexibility and more efficient heat distribution because you can direct the hot air straight to the workspace no matter where you need to locate the heater. One louver is included with every waste oil heater. An additional louver can be installed on the other side of a unit to distribute hot air from both sides.
Combustion and Fuel Delivery: AirScape
Our AirScape (patent pending) captures and purges air from the fuel line before it can reach the burner and become a nuisance. No waste oil heating system is immune from air entering the system as the air can be introduced through the oil, from high vacuum conditions and loose fittings. The AirScape will work with all brands of waste oil heaters.
Exhaust: Draft Inducer
Every environment is unique and in some cases a draft inducer is the best solution to get the consistency in performance you expect. Proper draft helps insure the heater lights reliably and has proper combustion every time. Easily adapted to any EnergyLogic heater, your Authorized Dealer can determine if a draft inducer is needed for your installation.
Exhaust: Flue Kit
Our flue kits work with any application and can address any need. Best of all, each kit is a complete package so you have everything you need for your unique requirements. Each UL-Listed flue kit includes a firestop, storm collar, (2) double-wall, Class A fuel-rated flue sections, a flue cap, ceiling trim piece and roof attachment kit.

Programmability: SmartStat
The SmartStat is waste oil heating’s only seven-day programmable thermostat with total system monitoring, fuel conservation and intelligence. It is the only device that eliminates guesswork and helps avoid nuisance shutdowns by providing feedback when an operating condition affects heater performance.

What is the average payback period on an EnergyLogic heater?It really depends on the weather in your area and on the alternative energy costs. On average, EnergyLogic heaters and boilers pay for themselves over one to two heating season.
What kind of oil can I burn?
- Any oil with a flashpoint of 400 degrees or less
- Up to 90 weight
- Motor oils
- Brake fluid
- Gear lubricants
- Automatic transmission fluid (ATF)
- Industrial oils
- Dirty diesel fuel
- Do not add gasoline, paint thinner, chlorinated solvents or antifreeze to your tank
Can I burn synthetic oil?
Yes – there must be at least a 50/50 mix with diesel, used transmission fluid (ATF), or used oil
Can I burn vegetable oil?
Yes – The vegetable oil must be at least 50 degrees to prevent clogging of the filters. Also, there has to be at lease a 50/50 mix with diesel, used transmission fluid, or used oil.
Is this the same heater that drips oil onto a hot surface?
Nope – this is a purpose designed and built combustion product that uses a fuel oil type burner with patented components to make it the most reliable waste oil burner in the industry.
Does it smell and create black smoke?
No – the exhaust on an EnergyLogic product is as clean as the emissions from a gas powered automobile.
Are Used-Oil heaters and boilers legal?
Yes – they are approved by the EPA (and other government agencies) and are UL listed.
When using the heater or boiler, does it produce any byproducts?
Yes – when burning used oil it does produce a very fine ash. This ash is safe to dispose of in normal waste disposal or in the ground like any normal ash.
How much fuel does each unit consume? How many BTU?
Model | Gallons/Hour | BTU |
EL140 Heater | 1.0 | 140,000 |
EL200 Heater | 1.4 | 200,000 |
EL350 Heater | 2.3 | 350,000 |
200B Boiler | 1.4 | 200,000 |
375B Boiler | 2.7 | 375,000 |
500B Boiler | 3.6 | 499,000 |
Good question – this really depends on a lot of factors like how high your ceilings are, how well your shop is insulated, do you have open doors (for service) and also on how severe the winter is in your region.
Below is a pretty safe estimate for our heater – boilers are more difficult to give a rough estimate for because they are used for many different purposes – just call us and we’ll help you figure out the best model for your application.
- EL140 Heater will heat approximately 3,500 square feet.
- EL200 Heater will heat approximately 5,000 square feet
- EL350 Heater will heat approximately 8,500 square feet
How many BTUs do I need to heat my shop?
Well – it depends on a number of factors – how well your shop is insulated, how high your ceilings are, what is the weather outside, do you have your service doors open a lot, and so forth. A quick rule of thumb is to plan for 30 to 50 BTU per sq foot. As an example – if you have a 40 x 50 shop building – that is 2000sq feet. 2000sq feet x 40 BTU = 80,000 BTUs – In this case, the 140H would easily heat the shop.
Can I duct the unit?
Yes – on either or both sides, but not from the top or the bottom.
How long can I make the duct?
We recommend keeping the duct under 30 feet in total length.
Can I pump the used oil from an outside tank? Unground tank?
Yes – a special transfer pump must be used and special consideration must be given to distance, temperature, type of oil, and so forth. We can help you with this – just give us a call.
Can I use a paper element filter to screen my oil?
Not recommended – paper filters deteriorate too quickly. A 140 micro stainless steel filter is recommended.
Can I run the flue pipe through the wall?
Yes – but with no more than a 45 degree angle and no more than 10 feet on the angle portion. Also the flue must be at least 4 feet above the highest point on the roof. These are standard heating flue venting standards. We can help you with designing your flue and supply you with the materials to make your heater run safely and optimally.
How often will I have to clean ash from the heater/boiler?
Every 1000 hours of operation. This is roughly equivalent to once a year for most installations. EnergyLogic heater are the easiest to clean by just removing the drip cap and sweeping the ash out of the heat exchanger – about 30 minutes of work.
What’s the deal with emissions and the EPA?
EnergyLogic heaters have been certified by the EPA and it meets or exceeds the regulations. The EPA has stated that it is safer and better for the environment to burn the oil on site than to risk the transportation of the used oil. You can read more about it in this summary document – click here
