If you live in the Northeast, there’s no question you need to be able to rely on your heating system fully throughout each winter and then some. Clean Burn used-oil heating systems are crafted to perform safely and efficiently in the coldest of weather.

Efficient Used-Oil Heating Equipment for Greater Savings

When comparing apples to apples, you will find a striking difference with a Clean Burn system, especially when it comes to its low stack temperature. The lower the stack temperature, the greater the furnace efficiency, which is shown by the image below.

Typical Clean Burn Stack Temperature = 450°
Typical Blast Tube Furnace Stack Temperature = 600° to 1,000°

Measuring Efficiency of Used-Oil Systems

Measuring the efficiency of used-oil furnaces is challenging because a clean furnace burns more efficiently than a dirty one. Ash residue from the combustion of used oil builds up inside the combustion chamber and gradually reduces the amount of heat transferred from the combustion chamber to the room air. This means that the precise efficiency level of any used-oil furnace is constantly changing depending on the amount of ash buildup in addition to other factors.

Fun and Frigid Facts

  • Clean Burn is the only used-oil furnace in service on the continent of Antarctica. Workers in government research facilities there stay warm in the world’s harshest environment with Clean Burn used-oil furnaces while helping protect the environment.
  • Dozens of Clean Burn units are currently functioning in Siberia—some at locations where other used-oil furnaces failed to function properly due to the extreme cold conditions.

Some people say, “I don’t care how efficient a used-oil furnace is. I’m burning free oil anyway.” While that’s true, if you run out of used oil because of low efficiency and high consumption, you will soon be paying a lot of money to your local fuel oil dealer to get you through the heating season—which essentially defeats the purpose of recycling your oil.

Clean Burn is a more efficient used-oil furnace and is far less expensive to operate over the long term. You can always burn excess used oil; you can’t always get free oil if you run out.

In the US, nearly all states and municipalities have adopted safety codes, which require that used-oil heating systems be UL (Underwriters Laboratories Inc.) listed. Clean Burn has worked closely with UL for years to help advance the safety standards of used-oil heating equipment. Our in-house testing facilities are unique in the used-oil equipment industry and are qualified by UL. All Clean Burn furnaces and boilers are UL listed and meet or exceed safety standards as required around the world, including CSA and C-UL in Canada, CE in Europe, and GOST-R in Russia.

Ducted Heating Systems

Clean Burn has worked closely with UL to develop UL-listed used-oil ducted central furnace systems. For applications where heating ducts are required, it is important to make sure that the manufacturer has obtained UL approval.

The Clean Burn Cold Weather Advantage

When do you need your used-oil furnace to work properly? The answer is when it’s cold, of course. Here in the Northeast, that’s just about half of every year! For the used-oil furnace that is the most reliable in the coldest conditions, your choice should be Clean Burn.
