Factors That Affect Heating Oil Usage

Below, we cover several factors that have an impact on how much fuel oil you use per day:

1. The Home’s Size And Design

The amount of home heating oil your home needs relies on its size and design. Larger homes require more heating compared to smaller houses. Even if the surrounding temperature is the same, larger homes will still have a higher heating oil consumption.

The home’s design is also a significant factor. Your home’s overall volume affects your heating requirements as well. Other factors that affect fuel consumption include the insulation quality and wall thickness of your home.

2. Ambient Temperature

The temperature in your surrounding area can significantly affect how much fuel you use. The colder the outdoor temperatures are, the more heating oil you use per day. For instance, a 15-degrees Fahrenheit drop will result in your household consuming double your usual heating oil usage.

3. Oil Furnace’s Condition

The oil furnace must be cleaned and maintained at all times. This will ensure that it functions at high efficiency. Therefore, have it tuned up at least annually, especially before the cold season begins. An efficient heating unit utilizes less heating oil.

Heating Oil Consumption Based On Temperature

The average capacity of oil tanks is 275 gallons. If your local temperature averages at 50 degrees Fahrenheit, you will likely use around 2 gallons daily. Hence, a full tank will last you approximately four and a half months or the entire winter season.

Unfortunately, temperature fluctuations happen during the cold season. A temperature drop results in higher heating oil use. As a matter of fact, a 10-degree drop from the average 50-degree temperature can result in consuming 3.7 gallons of heating oil. If the temperature remains at 40 degrees Fahrenheit throughout the season, then a full tank will only be sufficient for two and a half months.

When the temperature goes down to 20 degrees Fahrenheit, the average home needs around 7 gallons of oil daily. As a result, a full tank will only be sufficient for 39 days if the temperature consistently stays the same throughout the season.

The temperatures typically fluctuate from the 20s to the 40s, averaging 30 degrees Fahrenheit during winter. This leads to your home using around 5.3 gallons of heating oil a day, so a full tank will last for a month and three weeks during the coldest months.

A 275-gallon tank can typically support an average-sized home. Check your home’s tank size to determine if you might have a smaller tank installed. This way, you can estimate your fuel use and know when you need to fill your tank again.


Use Historical Statistics To Estimate Your Heating Oil Needs

The information from your past heating bills can help you determine the daily, monthly, and annual heating oil consumption values of your household. Therefore, make sure that you keep a record of your home’s yearly heating oil consumption. However, remember that this is only possible if you’ve lived in the same house for several years.

If you recently moved into a new neighborhood, look for houses of similar size to yours. You can ask neighbors about their heating oil consumption to give you an idea of how much oil you’ll use in a day. You can call the local heating oil supplier to help you as well.

Average Heating Oil Usage Based On Square Footage

The home’s size has a significant impact on how much heating oil your home uses. The average American home has a size of 2,687 square feet. However, your home might be smaller or larger than this.

The following estimates are what your house needs for every 1,000 square footage in comparison to the average ambient temperature:

  • 3.27 gallons for 10 degrees Fahrenheit
  • 2.67 gallons for 20 degrees Fahrenheit
  • 2.07 gallons for 30 degrees Fahrenheit
  • 1.47 gallons for 40 degrees Fahrenheit
  • 0.87 gallons for 50 degrees Fahrenheit

For example, if your home has a size of 3,500 square feet, you will need 3.5 times the average requirements listed above. Therefore, a typical day with a temperature of 40 degrees Fahrenheit will consume 5.15 gallons of heating oil.

Heating Oil For Water Heaters

Water heaters can be powered by natural gas, propane, electricity, and heating oil. If both your water heater and heating system use heating oil, you need to adjust your calculation. Water heaters typically consume around 0.5 to 1.0 gallons of heating oil per day. This depends on your home’s size and how many residents shower every day.
