When you have a waste oil burner, be it your furnace or boiler, you cannot neglect it. This is not a device you can spend several thousand on and just leave it. There are many machines and items you can buy for your everyday needs that require little maintenance and waste oil burners are not one of them.

You must get an annual tune-up every single year. Your system needs to be checked, cleaned, and tuned for it to continue working right. Certified technicians that work on waste oil heaters have special tools and analyzers to scan your system. If necessary they clean the device and the heat exchanger, replace the nozzle head, and change the fuel and air filter. The wiring is also checked and the ignitor is inspected to make sure it is firing the correct way.

Getting the annual inspections done is crucial. But, there is still more that needs to be on a daily and weekly level.

A waste oil burner’s primary fuel is used motor oil. This substance is dirty and contaminated. You must do the best job you can at filtering it. You want to get as much dirt and sludge out of there as you possibly can. The same applies for moisture. Its waste oil so it is never going to be 100% clean unless you put it through a centrifuge which can clean close to 95% of all the dirty and water out in my opinion. But you want to do your best to filter it as much as you humanly can. This can be accomplished by putting it through several 20-30 micron oil filters.

Never want to put a fresh batch of used Motorolja fat motor oil into your main holding tank. The oil should sit for a couple days in a separate tank so all the crude can settle to the bottom. Then, you want to utilize some sort of suction wand, powered by a powerful pump, and suck all the oil out of it into your main holding tank without letting the tip of the want touch the last couple inches of the barrel. This way you get all the motor oil without the sludge which by now has settled bellow.

Make certain little water and absolutely no antifreeze gets into your supply. Too much of these two materials will harm your expensive waste oil burner. If a batch is contaminated with a lot of water or antifreeze get rid of it at the dump (you may have to pay). Do not just run it through your system and think it will be okay.

These waste oil heaters (burners) are great investments. They allow you to heat your business or shop for nothing. The savings can be huge. However, you must maintain your equipment for it to last.
