The Efficiency Of Oil

Installation and Service
An Oil heat system's efficiency is a measurement of the usable heat extracted from the potential energy of the fuel. For example, if your system is evaluated at 85%, that means that 85 cents of every dollar spent for heat is consumed in the home. 

The U.S. Department of Energy makes calculations of efficiency yearly called AFUE - the Annual Fuel Utilization Efficiency. Using this analysis, Oil heat gets excellent ratings; the efficiency of Oil heat ranges between 83% and 94%. By contrast the efficiency of gas units is between 78% and 95%. 

The average oil heat system in operation today is more efficient then natural gas and although the high-end ratings of gas appear to be attractive, these units exhibit higher water vapor exhaust which can be corrosive and cause more frequent replacement of the equipment.

Another way of measuring Oil heat efficiency is to use British Thermal Units (BTUs). One BTU is the heat needed to warm the temperature of one gallon of water one degree Fahrenheit. On a per gallon equivalent basis, heating oil has more BTUs than other sources of space heating. Take a look:

  • Heating Oil: 139,690 BTU's per gallon
       
  • Natural Gas: 100,000 BTU's per Therm (1.4 therms equal one gallon of heating oil)
       
  • Kerosene: 131,890 BTU's per gallon (1.05 gallons equal one gallon of heating oil)
       
  • Propane: 91,500 BTU's per gallon (1.52 gallons equal one gallon of heating oil)
       
  • Electricity: 3,413 BTU's per Khw (40.6 Khw equals one gallon of heating oil)

   

Davis Oil Service provides unsurpassed service, installation and maintenance on your heating systems.

 

 

 

 
   

Oil Vs. Gas, Electricity & Propane

Discount Fuels?
Over the years, both the public and private sector have conducted numerous studies in order to determine the efficiency of oil, natural gas, electricity and propane. Time and time again, the results have remained unchanged: Oil heat's economical, environmental and technological benefits are unsurpassed.
  • Oil heat is the most reliable of all home heating energies.
  • Oil produces more BTU's per gallon then other fuels, therefore making it a more efficient choice.
  • Unlike propane or natural gas, home heating oil is neither flammable nor explosive.
  • Residential oil burner particulate emissions are now approaching near-zero levels.
  • Oil heat produces fewer greenhouse gas emissions than natural gas, so it is better for the environment.

Within recent years, several local companies have gone into business offering "discount fuels".

As a consumer, you should know that lesser grade fuels often shorten the life span of your filters and equipment. Also, most of these carriers do not offer comprehensive maintenance or service of your equipment, which may also cost you more money in repairs and replacement costs.
