Calculating 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 use a spray nozzle that delivers oil at a flow rate ranging from 0.8 to 1.7 gallons per hour. Additionally, you’ll need to know the size of your oil tank and the current oil level (if it’s not full).

According to the given calculation, if your oil consumption rate is 1.7 gallons per hour and you spend approximately 10 hours at home each day, you would use around 17 gallons of oil daily. As a result, a 330-gallon tank would typically last you approximately 19 days (330-gallon tank divided by 17 gallons per day equals 19.4 days).

How much heating oil does my home use in a day?

To provide you with a rough estimate based on the average home size of 2,400 square feet, here’s a useful guideline. Assuming that the average outdoor temperatures remain around 32° throughout a 24-hour period, a home of that size would consume approximately six to seven gallons of heating oil per day. It’s important to note that if temperatures stay above freezing and you live in a smaller home, your daily heating oil usage would be lower.

The following table provides an estimation of your daily heating oil consumption based on the outside temperature.

How do I know how much heating oil is in my tank?

On the heating oil tank, there is a transparent glass or plastic cube that resembles a fuel gauge in a car. It is marked with numbers: F, ¾, ½, ¼. Typically, a red marker or float indicates the remaining fuel level in the tank. If the float is at the bottom or not visible, it means that the tank is either empty or nearly empty.

If you suspect any malfunctioning with the gauge, please contact us immediately. Your heating oil supply should not be left to guesswork.
