Heating Oil Usage Calculator


What is Heating Oil Usage Calculator?

A Heating Oil Usage Calculator is a tool used to estimate the amount of heating oil required for a home or building based on the total usage and home size. The calculator provides an estimate of heating oil consumption in gallons per square foot (gallons/ft²).

Formula and Example

The formula used to calculate the heating oil usage is:


where HOU is the Heating Oil Usage in gallons/ft², TU is the Total Usage in gallons, and HS is the Home Size in square feet.

For example, let’s assume a home with a total usage of 800 gallons and a home size of 2,000 ft². To calculate the heating oil usage, we can use the formula:

HOU = 800 / 2000 = 0.4 gallons/ft²

Therefore, the estimated heating oil usage for this home is 0.4 gallons per square foot.

How to Calculate Using the Heating Oil Usage Calculator

To use the Heating Oil Usage Calculator, simply input the total usage and home size in the provided fields and click the “Calculate” button. The calculator will automatically calculate the heating oil usage and display the result in gallons/ft².


What is the difference between heating oil and natural gas?

Heating oil is a liquid fuel that is stored in a tank and delivered to a heating system, while natural gas is a gas that is supplied through pipelines.

Is heating oil consumption affected by the weather?

Yes, colder weather can increase heating oil consumption as the heating system needs to work harder to maintain a comfortable temperature.

How often should I check my heating oil tank?

It is recommended to check your heating oil tank regularly, at least once a month, to ensure that you have enough fuel for the winter season.


The Heating Oil Usage Calculator is a useful tool for homeowners and building managers to estimate their heating oil consumption based on their total usage and home size. By using this calculator, they can plan and budget for their heating oil needs and ensure that they have enough fuel to keep their home or building warm throughout the winter season.
