How much oil does a used-oil burner use?

Depending on the model, EnergyLogic heaters and boilers burn 1-3.5 gallons per hour of running time and can recycle dozens to thousands of gallons per year... and every drop removes waste from the environment while lowering the demand for other heating fuels.

Waste-oil contains a tremendous amount of valuable energy, and EnergyLogic has spent over three decades figuring out how to get the most from it. EnergyLogic’s advanced used-oil burner platform can convert ~140,000 BTU of clean energy from each gallon of fuel per hour of continuous run time. Of course, different facilities require different amounts of heat and fuel consumption will vary, as the heater will not need to run continuously to heat the space.

EnergyLogic develops systems for facilities of all shapes and sizes. CONTACT US today and let our experience work for you.

How much money can a waste-oil furnace save me?

Each gallon of waste oil recycled saves you $1-$7...

By offsetting or eliminating heating and waste-oil disposal costs,  an EnergyLogic used-oil recycling system can save you thousands of dollars per year (or even per month, depending on your facility) and will generally pay for itself within the first few years of operation. And with our financing options, you can start saving immediately without paying out-of-pocket.

Take a look at our Estimated Return on Investment Calculator developed to help you get an idea of just how much your waste-oil could be worth.

What maintenance does a waste-oil heater or boiler need?

Waste-oil heaters need annual maintenance to prepare for heating season and ash removal at regular intervals. EenrgyLogic is designed around the central goal of making this maintenance as easy as possible, with the most time between services.

EnergyLogic makes recycling waste oil into clean energy easy. Still, some maintenance routines are necessary to keep your system running at peak efficiency. Be sure to avoid collecting contaminates in your used-oil tank and periodically drain any water and remove any sludge that may build up. And while EnergyLogic’s ADVANCED COMBUSTION TECHNOLOGY creates an ultra-hot flame for an exceptionally clean burn, recycled fuel oils contain some non-combustible components which are left behind in the combustion chamber as ash and need to be removed regularly. Your used-oil heater or boiler should be serviced every 500-1000 hours of operation to remove ash, change filters, and drain water or remove other contaminants from the fuel tank.

EnergyLogic makes easy service a core principle of our design, from how it’s built to how we support service. Take a look at our HOW-TO VIDEOS to see helpful guides about the service process, or CONTACT US to inquire about field-service visits and turn-key service agreements with our expert DEALER NETWORK.

Don’t waste-oil burners need a lot of adjustment and messing with?

Some do. EnergyLogic burners don’t.

Waste-oil heaters have come a long way since the DIY drip drums and fire boxes of past decades, though some manufacturers still rely on external atomizing air and oil-pressure regulators to achieve a proper, clean combustion burn. These approaches can introduce problematic moisture, dust, and fuel-delivery inconsistency into your system, requiring adjustments as air usage, temperature, and fuel types vary.

EnergyLogic holds the need to keep it simple and make used-oil recycling “turn-key” central to our approach, so that more people can enjoy the heat they get from responsibly converting their waste-oil into clean energy, without having to become a heater technician in the process. EnergyLogic’s Steady-Flo Metering Pump and On-board Air Compressor provide dedicated sources of consistent fuel delivery and atomization while automatically compensating for changes in fuel density and viscosity, so you can recycle more types of oil and mess with it less.

Do I have to hook my shop air compressor up to a used-oil burner?

Not with EnergyLogic! An on-board air compressor comes standard, so your waste-oil burner gets clean, consistent atomizing air, allowing you to let the heater keep your shop from freezing overnight while safely shutting down your shop-air compressor. Find out more about the BENEFITS ON AN ONBOARD AIR COMPRESSOR.

Do waste-oil heaters and boilers give off fumes or smell?

Many waste-oil burners require external shop air or charge extra for an optional on-board air compressor. EnergyLogic comes with an integrated on-board air compressor, standard.

Some waste oil can have a strong smell, depending on its source, and some waste-oil heaters and boilers do not manage fuel delivery and combustion exhaust all that well.

A modern used-oil heater or boiler, like EnergyLogic’s, includes systems and recommendations for managing these materials so that fumes or smells are not  released into the occupied space around the furnace.

The most important contributors to this are to ensure that the used-oil storage tank is properly vented to the exterior of the structure and the furnace has an appropriate chimney flue installed with sufficient draft. Check out EnergyLogic’s HOW-TO VIDEOS for recommendations and CONTACTING US to get in touch with a factory-trained installation expert.

What size / model waste-oil heater or boiler do I need for my space?

Most workspaces require an average fuel input of about 2.5 BTU/hr per cubic foot of conditioned space to maintain a comfortable temperature during the coldest time of year.

EnergyLogic offers VARIOUS MODELS of used-oil heaters and boilers that cover from 3500 square feet up to 12000 square feet each and can mixed and matched to heat spaces or processes of all shapes and sizes, large and small. There can be many factors in selecting the system that’s just right for your application. Many facilities can also benefit greatly from adding large HVLS fans to their heating system to balance and distribute heat throughout their space while providing comfort and health benefits year-round.

Can I install my waste-oil furnace myself?

Yes!..

Many happy EnergyLogic used-oil furnace owners have taken the DIY approach to installation. In fact, EnergyLogic designed its COMPLETE SYSTEM specifically for making installation and maintenance as simple as possible. We also offer a full course of HOW-TO VIDEOS to walk you through the process, step by step… and if at any point you decide to turn it over to an expert, our DEALER NETWORK is standing by.

Can I have elbows and horizontal sections of chimney-flue pipe?

Yes, but it’s not recommended.  EnergyLogic used-oil heaters and boilers are designed to minimize or eliminate horizon runs and right angles.

Proper draft is critical to achieving a clean, efficient burn when recycling used-oil. When installing the chimney flue for a waste-oil heater, it is important to consider the eventual need to clean the pipe, as well as allowing any ash that enters the pipe to fall back into the furnace or trap for regular removal. Offset kits of up to 30 degrees are available to align the furnace outlet with a roof penetration, or if absolutely necessary, through the sidewall of the building envelope. Elbows and extra fittings should be minimized, horizontal sections should be avoided, all portions of the flue should be accessible to a sweep, and flue should never be shared with any other equipment (even another waste-oil furnace). Watch our HOW-TO VIDEOS for more installation and maintenance tips & tricks.

Can an EnergyLogic used-oil heater been attached to ductwork?

EnergyLogic forced-air heaters are designed to be vented directly (without ducting) into the conditioned space for best results.

Units have been successfully ducted to distribute heat farther from the unit or to heat an adjacent space, but care must be taken to maintain appropriate static pressure on the blower and avoid draft issues caused by joining rooms of different airflow dynamics. If you wish to duct an EnergyLogic used-oil heater, consult both the manual and an HVAC specialist.

Where heat distribution is the main concern, a MACROAIR HVLS FAN is a wonderful solution that works quite well with our heaters and boilers, and can extend their coverage area. Large commercial-industrial HVLS fans can very-effectively fully replace HVAC-system ductwork in large spaces, for both heating and cooling, while having the added benefit of improving indoor air quality and reducing condensation and SWEATY-SLAB SYNDROME. Cost savings from adding HVLS fans can quickly recoup the investment while savings, comfort, and health benefits continue for many years after.

Who can I get to work on my EnergyLogic used-oil burner?

EnergyLogic has an extensive DEALER NETWORK of qualified technicians that can service your equipment. CONTACT US to inquire. We also offer step-by-step HOW-TO VIDEOS to make regular maintenance easy to DIY, if you’d prefer.

How does EnergyLogic achieve a “hotter flame”?

EnergyLogic’s used-oil combustion process combines the best technologies to create extremely high temperatures in the core of its blast flame.

Let’s get DEEP INTO THE SCIENCE of combustion engineering and how EnergyLogic optimizes the simple elements of fuel, spark, and air to create the cleanest, most efficient burn. EnergyLogic used-oil burners apply decades of experience and expertise to dial in combustion conditions and increase core temperatures to levels capable of burning the most challenging fuels and synthetic used-oils while improving containment and exhaust emissions. Standard options like the large preheater, Steady-Flo Metering Pump, On-board Air Compressor, and patented flame-retention head create a dynamic system that maintains clean energy conversion without the need for adjustments, making sure that you get the most value and environmental benefit from the broadest range of fuel types, with ease.

What does it mean that EnergyLogic creates a “complete burn” of heating fuel?

Inefficient combustion can leave unburned fuel and other impurities unconverted in the stoichiometric chemical process, giving you less heat and more smoke & ash to clean up.

The advanced combustion technology used in an EnergyLogic multi-fuel burner achieves flame temperatures hot enough to consume impurities in the WIDEST RANGE of new and recycled fuel oils (including synthetic oils), creating a clean burn, minimizing ash deposits, prolonging efficiency between maintenance, and lengthening maintenance cycles... another example of how EnergyLogic is designed and built to be the easiest waste-oil heater to own and operate.

What’s the difference between a carbon-steel & a stainless-steel heat exchanger?

Easy. A stainless-steel waste-oil heater is built to last.

Carbon steel is a durable, cost-effective material for many modern applications, including some HVAC components. However, because of the nature of recycling used-oil for heat, carbon-steel combustion chambers for waste-oil heaters can experience reduced material reliability when compared to their natural-gas counterparts. EnergyLogic uses stainless-steel heat exchangers because of the extended product life they offer for waste-oil recycling, due to stainless-steel’s stabile thermal properties and corrosion resistance. Some competing manufacturers have argued that carbon steel is a better conductor of heat than stainless steel. While this is true at room temperature, at the temperatures found in a combustion chamber carbon steel gets much closer to its destabilizing temperature than stainless steel and their respective heat conducting values approach similarity. Both materials’ heat-conducting values are almost 1000-time greater than the ability of air to conduct this heat, meaning the air itself, not the metal, is the limiter of heating and cost-vs.-durability is the bigger consideration when choosing a heat-exchanger material.

What does “double the heat rise” mean?

EnergyLogic Used-oil heaters put out air that is as much as 120 °F hotter than the air taken in... that’s twice the increase of most waste-oil heaters.

An ultra-hot flame and stainless-steel heat exchanger let EnergyLogic’s used-oil heaters focus on efficient, clean energy conversion to turn what would be potentially-hazardous waste oil (when spilled or disposed of improperly) into a free green fuel. The burner’s optimized clean burn and heat-tolerant combustion-chamber material allow EnergyLogic FURNACES to maximize heat transfer through the forced-air handler, reducing air speed and CFM (which can create a chilling breeze when too high) and increasing ambient air temperature by 100 °F – 120 °F (as much as two-times the temperature rise achieved by the competition).

Is heat being lost through the chimney flue? How does “stack temperature” affect efficiency?

Yes, but EnergyLogic’s high stack temperature is actually a sign you’re losing less energy.

It’s true that some heat is lost through the chimney, and 100% efficiency is not possible with combustion. Air must flow through and exhaust must be removed. EnergyLogic draws on advanced engineering and decades of experience burning used-oil to optimize waste-oil combustion by slowing it down, moving less air through but at higher temperatures, and keeping more heat inside the combustion zone. This minimizes make-up air and maximizes efficiency. EnergyLogic multi-fuel units operate at 75%-80% efficiency, even on 90W and heavy weight synthetic oils, and have an intentionally-high stack temperature to ensure that whole system can easily break down and evacuate impurities, burn high-flashpoint fuels, and deliver the greatest amount of heat (and VALUE) to your workspace.
