What is Oil Furnace? | How does an Oil Furnace work?

The oil boilers and furnaces are ideal in regions where a natural gas supply is limited. In the oil furnace, oil uses a working fuel. These furnaces have low costs than gas furnaces. If you live in an area where natural gas is not accessible then an oil furnace is a best choice. This article explains the various aspects of the oil furnace.

What is an Oil Furnace?

A furnace that uses oil to produce heat is known as an oil furnace. The oil furnaces have the capability to heat homes with renewable fuels. Different manufacturers are now offering kerosene blended with biodiesel, allowing customers to use domestic energy while reducing their dependence on foreign oil.

In an oil-fired furnace, the combustion of the oil takes place in the combustion chamber of the furnace. Due to the oil combustion, heat is generated, which is transferred to the indoor air. As the indoor air gets heat, it heats the room. The furnace has a thermostat used to control the flow of heat produced by the combusted gas.

Oil furnaces are environmentally friendly and have a very low emission rate than other type of furnaces.

These furnaces have an easy repair or service, but dirt and soot build-up make servicing more difficult. Therefore, these furnaces have high maintenance costs. You must regularly clean the oil filters and chimney for the efficient working of the furnace. 

Oil furnaces have low cost than gas furnaces, but they are less efficient and have higher fuel prices than gas furnaces.

Advantages of Oil Furnace

  1. The primary role of the furnace is to heat the air in your home. The oil furnace heats up the indoor air faster than other heat furnaces.
  2. These furnaces have low initial costs. They are considered the number one heat generator of all types. This means you can warm up faster than ever without delaying your day.
  3. They have a 20 percent low cost than same capacity gas furnaces. This means you can cool your home for a very low price. Everyone loves to save money, and this is a great way to do it.

  7. These furnaces have a low emission rate.

Disadvantages of Oil Furnaces

  1. These furnaces are less efficient than gas furnaces.
  2. Oil fuel has a high cost.
  3. Oil furnaces need a place to get oil. For this reason, you need to install a fuel storage tank under the house. This increases the cost of the furnace and also increases its weight.
  4. Gas and electric furnaces typically use cheap electricity. However, oil prices remain high. Therefore, the monthly cost of running the oil furnace will be higher.
  5. You must always keep your tank full of oil to prevent the furnace from temperature drops. This means you need an extra person or company who can deliver and offload oil to the tanks on a regular basis.

Maintenance of Oil Fuel Furnace

  1. Clean the filter: The filters are the most important component of the furnace. The oil furnace has an air filter and oil filter. The filter keeps dust and dirt out of the heating system. The cleaning and maintenance of the filters are very impotent for the proper operation of the furnace. To clean the filters, you must follow the manufacturer’s instructions given in the product manual. The filter should be replaced every 3 months, but if you have smokers or pets in your household, you may need to replace the filter more frequently.
  2. Check for smoke: Few furnaces emit smoke from the furnace exhaust pipe or chimney. Inspect the smoke regularly while the system is running to observe the color of the smoke. If the smoke has black color, this means that the oil isn’t burning properly and your system requires an urgent repair to work efficiently. 
  3. Clean the nozzles: Maximum people hire a professional for the regular maintenance and cleaning of the furnace nozzles, but after reading the manual carefully, you can do this job yourself. Check the position of the nozzle according to the instructions and clean it about once a month to avoid dangerous clogging.
