Pros & Cons of Oil Furnaces

  • Oil furnaces provide more heat per BTU
  • Less upfront costs than a gas furnace
  • Inhalation of oil fumes in not potentially fatal unlike gas
  • System malfunctions can be easily detected

Although oil furnaces have a smaller upfront cost, the cost of heating the oil is more expensive than natural gas. Oil also needs to be stored and refilled in a tank because of the lack of pipeline infrastructure compared to gas intake. Oil furnaces also require more extensive maintenance.

Pros & Cons of Gas Furnaces

  • Gas furnaces have a higher heating efficiency
  • Fuel costs less but you need a home with gas supply available
  • Less maintenance is required for gas furnaces
  • Gas furnaces are also quieter and cleaner than oil furnaces

Gas furnaces do however produce less BTUs compared to heating oil and are more expensive than their oil counterparts. Gas furnaces also present more of a safety risk because gases can be emitted without warning – and the gas is highly combustible. Rigorous safety precautions must be exercised when performing routine maintenance and check-ups.


Furnace Efficiency & Cost

One of the most important factors that is considered when deciding how to heat your home is the efficiency rating of the furnace. The efficiency rating of a furnace is measured by a rating called the Annual Fuel Utilization Efficiency (AFUE). The AFUE rating evaluates the efficiency of combustion, for which a higher rating means the efficiency is better.

Oil furnaces typically have an AFUE rating between 80 – 90%. Meanwhile gas furnaces have a rating of 89 – 98%.

Although gas furnaces are more efficient and the cost of gas is cheaper than oil, the upfront cost of installing a gas furnace compared to its oil counterpart can be up to 25% higher. However, an oil furnace requires more frequent cleaning and maintenance.
