If you’re curious about the duration of your heating oil supply, the answer isn’t straightforward. Various factors, including your home’s size, insulation quality, and the efficiency of your oil-fired heating system, influence oil consumption. However, we’ve gathered some valuable insights about heating oil and its usage to provide you with an estimate of how long a full tank of heating oil may last in your home.

How to calculate your heating oil usage

Here’s a calculation that can provide an approximate estimate of your oil usage based on the running time of your oil burner in minutes per hour. It’s important to note that oil burners utilize a spray nozzle that delivers oil at a flow rate ranging from 0.8 to 1.7 gallons per hour. Additionally, you will need to know the size of your oil tank and the current oil level (if it is not full).

Based on the provided calculation, if your oil consumption rate is 1.7 gallons per hour and you spend around 10 hours at home each day, you would use approximately 17 gallons of oil daily. Consequently, a 330-gallon tank would typically last you for approximately 19 days (dividing the 330-gallon tank by 17 gallons per day gives us 19.4 days).

How to calculate your daily heating oil usage

For an estimated usage based on an average home size of 2,400 square feet, here’s a helpful guideline. Assuming that outdoor temperatures hover around 32° throughout the day, a home of that size would typically consume approximately six to seven gallons of heating oil per day. It’s important to note that if temperatures remain above freezing and you reside in a smaller home, your daily heating oil consumption would be lower.

The table below presents an estimate of your daily heating oil usage, taking into account the outside temperature.

Average outside temperature Gallons of heating oil used per day
15° 7.8
20° 7.0
25° 6.2
30 ° 5.3
35° 4.5
40° 3.7
45° 2.8
50° 2.0

How to read your heating oil tank gauge

The heating oil tank is equipped with a transparent glass or plastic cube that resembles a fuel gauge found in cars. This gauge is conveniently marked with numerical indicators: F, ¾, ½, ¼. A red marker or float is typically used to indicate the remaining fuel level in the tank. If the float is positioned at the bottom or is not visible, it signifies that the tank is either empty or nearly empty.

If you notice any issues with the gauge, please get in touch with us right away. Don’t leave the management of your heating oil supply to chance or uncertainty.
