Enter the total usage (gallons) and the home size (ft^2) into the Calculator. The calculator will evaluate the Heating Oil Usage. 

Heating Oil Usage Formula

HOU = TU / HS

Variables:

  • HOU is the Heating Oil Usage (gallons/ft^2)
  • TU is the total usage (gallons)
  • HS is the home size (ft^2)

To calculate Heating Oil Usage, divide the total usage in gallons by the home size.

How to Calculate Heating Oil Usage?

The following steps outline how to calculate the Heating Oil Usage.


  1. First, determine the total usage (gallons). 
  2. Next, determine the home size (ft^2). 
  3. Next, gather the formula from above = HOU = TU / HS.
  4. Finally, calculate the Heating Oil Usage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total usage (gallons) = 200

home size (ft^2) = 5000

FAQs

What factors can affect heating oil usage in a home?

Several factors can affect heating oil usage, including the insulation quality of the home, the efficiency of the heating system, outdoor temperatures, and the thermostat settings. Homes with poor insulation or inefficient heating systems may use more heating oil.

How can I reduce my heating oil usage?

To reduce heating oil usage, consider improving home insulation, sealing leaks around doors and windows, using programmable thermostats, maintaining your heating system regularly, and considering upgrading to a more efficient heating system.

Is heating oil usage calculated differently for different home sizes?

While the basic formula for calculating heating oil usage (gallons/ft^2) remains the same, larger homes may require more heating oil due to the greater area to be heated. However, factors like insulation and heating system efficiency play a significant role in the actual usage.
