Oil heating furnace is probably the most durable and most reliable type of heating equipment you can install in your home. Properly maintained oil furnace or boiler can offer 20 years and beyond of reliable and efficient service, which is almost twice longer than for gas furnaces. All you need is to follow these important maintenance tasks when needed.

  1. Schedule annual check-up and tune-up

This maintenance task is somewhat similar to car tune-ups. You should hire a certified technician to thoroughly inspect your oil heating system and replace some short-lasting parts which includes air and oil filters, and clean up the spraying nozzle which is the core part of the device – it sprays the oil into the combustion chamber and directly determines its fuel efficiency, but also length of life.

  1. Monitor possible oil spills

Oil spills can happen below the tank, pipelines connecting the tank to the furnace, of burner. Sometimes, these spills are really hard to detect, especially if your oil tank is underground or if pipes are built in the walls. In cases like this, oil spills can only be detected as a difference between the expected and actual levels of oil in the tank. Spills can cause drastic fall in levels of oil and your furnace can draw some of bottom oil sludge as a consequence. This can be detrimental for the furnace.

Oil spills from the burner are even more dangerous. These can cause major failures or even fires.

  1. Clean or replace air filters often

Forced air filters need to be thoroughly cleaned and replaced several times throughout each season, most commonly once a month from October through March. This will help the furnace work efficiently and consume less power and oil. Additionally, it will have less hours of work which extends its life.

  1. Clean the nozzle as often as possible

Although regular tune-ups include nozzle cleaning, you should have oil impurities on your mind. Buying high quality oil and regular filter replacement will most likely minimize the hazard, but you should remain careful even with high quality oil. Check the burner nozzle often and clean it whenever you see the furnace is losing efficiency.

  1. Oil tank maintenance

Many people neglect their oil tank thinking it’s just a common metal container. The problem is that corrosion may happen from the inside. Over the years, especially if you buy low quality oil, oil sludge will form on the tank’s bottom. It will be a home to millions of bacteria which produce aggressive chemical compounds that will make the tank corrode from the inside. In most cases, it will not be noticed before the spill occurs. Buy high quality oil or put additives into your oil to prevent forming of the oil sludge. Order more oil before its levels fall below the quarter of your tank capacity. Inspect your tank oil levels regularly, at least once a week. If you have an underground tank, consider replacing it.
