If you’re using heating oil to warm your home in the cold months, it’s important that you always have sufficient fuel in your oil tank to last and meet your home heating requirements.

When we mention this to our clients, the very first question they ask is, “How much heating oil will I use a day?” And this is very important to know as it helps you estimate how long one tank can last.

In this article, we’ll discuss the answer to this question. So, keep on reading…

Factors That Affect Heating Oil Usage

There are three factors that can affect your heating oil usage:

  • The size and design of your home
  • Ambient temperature
  • Condition of oil furnace

Let’s discuss each below…

1. The Size And Design Of Your Home

When it comes to size, larger homes generally require more heating oil than smaller ones. This is even if the two houses are of the same ambient temperature.

But apart from the size, the design also plays a crucial factor. The overall volume of your interior, like the thickness of the walls and the insulation quality, can affect your fuel consumption. Two homes with the same square footage can have different oil consumption, depending on the design.

2. Ambient Temperature

Another factor is the ambient temperature.

Naturally, homes in areas with colder ambient temperatures will use more heating oil than those in warmer areas. Even if a temperature drops at only 15 °F, your oil consumption can immediately double even in just a day.

3. Condition Of The Oil Furnace

You should also check the condition of your oil furnace and make sure that it’s clean and well-maintained, so it functions efficiently. Have it serviced at least once a year so it continues to perform well and won’t consume more oil than necessary.

Heating Oil Consumption Based On Temperature

A typical home uses about 2 gallons of heating oil per day if the outside temperature is 50 °F.

So, if you’re using an oil tank with a 275-gallon capacity, it can last about 137.5 days or around four and a half months when full. It’s basically all you need for the entire cold season.

However, from what we all know, temperatures always fluctuate during winter. And as mentioned above, even if the temperature drops by just 10 °F, your heating oil consumption will also increase.

For example, if the outside temperature is 40 °F, you need around 3.7 gallons of heating oil per day. When the temperature drops to 30 °F, you need to use around 7 gallons of heating oil per day.

With this in mind, it’s natural that the temperature would be 40-degrees one day and 20-degrees Fahrenheit the next day. So on average, one home demands around 5.3 gallons of heating oil in a day, which means that a full tank can last for 52 days or one month and three weeks.

Therefore, if you’re using a 275-gallon tank, that would most likely be enough.

However, if you’re using a smaller tank, try to estimate your fuel consumption requirements based on the calculations above to determine when to get your tank refilled.

Estimate Your Heating Oil Requirements Based On Historical Statistics

If you’ve been living in your home for years, make sure that you keep a record of your annual fuel consumption. This will help you calculate your average daily, monthly, and yearly heating oil consumption so you wouldn’t have to guess.

However, if you’re new to the neighborhood and don’t have any record of heating oil consumption, you can check similar-sized homes around you. You can then ask your neighbors about their oil heating use to estimate how much you’d need per day.

You can do this or contact a heating oil supply company near you, like Tower Energy, to help you get an estimate.

Average Heating Oil Usage-Based On Square Footage

As mentioned above, the size of your home can greatly affect your average home heating oil usage.

Below, we list down the estimated fuel consumption for every 1,000 square feet of space in relation to the average temperature outside:

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

In other words, if the average home in the US is at 2,687 square feet, you’d be using 5.56 gallons of oil in a 30-degree day. However, if you have a bigger home with, let’s say, a 3,500 square feet space, you’ll need around 3.5 times more heating oil than what’s listed above. The same goes if your home is smaller.

So, try to determine the size of your home and calculate based on the estimates above.

Heating Oil For Water Heaters

If you’re using heating oil for your water heater, then you need to make a few adjustments in your calculation.

Depending on the size of your home or how many of your family members showers daily, water heaters would require around 0.5 to 1.0 gallons of heating fuel per day. Calculate this, and depending on what number you come up with, add that to the daily home consumption.


Final Word

Bottom line, it’s not as hard to figure out how much heating oil you’d need in a day. By simply looking at the ambient temperature, your home size, and your home’s historical statistics, you can already get a number.

However, if you are new to the neighborhood, you can talk to neighbors and ask about their heating oil consumption. Or you can try the easier way, which is calling a heating oil provider in your area to give you an educated estimate.
