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 furnaces and boilers legal?
Yes – they are approved by the EPA (and other government agencies) and are UL listed.
When using the furnace 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?
How much space does each unit heat?
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 furnaces – 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.
- EL150 Furnace will heat approximately 3,500 square feet.
- EL200 Furnace will heat approximately 5,000 square feet
- EL350 Furnace will heat approximately 8,500 square feet
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 furnace run safely and optimally.
How often will I have to clean ash from the furnace/boiler?
Every 1000 hours of operation. This is roughly equivalent to once a year for most installations. EnergyLogic furnaces 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.
