Be sure about your heating oil supply with Automatic Delivery from Johnny Prescott

heating oil concord, nh Determining the duration of your heating oil supply can be a complex matter. Several factors, such as the size of your home, the quality of insulation, and the efficiency of your oil-fired heating system, all play a role in oil consumption.

However, we’ve gathered valuable insights on heating oil usage to provide you with an estimate of how long a full tank of heating oil might last in your home.

How long will my heating oil last?

Here’s a calculation that can provide an approximate estimate of your oil usage based on the running time of your oil burner 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 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 rate of oil consumption is 1.7 gallons per hour and you spend approximately 10 hours at home each day, you would consume roughly 17 gallons of oil daily. As a result, a 330-gallon tank would typically last you for around 19 days (dividing the 330-gallon tank by 17 gallons per day yields approximately 19.4 days).

How to calculate your daily heating oil usage

Here’s a useful guideline for estimating heating oil usage in an average home size of 2,400 square feet. Assuming outdoor temperatures around 32° throughout the day, a home of this size would typically consume approximately six to seven gallons of heating oil per day. It’s worth noting that if temperatures remain above freezing and you live 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 commonly found in cars. This gauge is conveniently marked with numerical indicators: “Full”, “Three-Quarters”, “Half”, and “Quarter”. A red marker or float is typically utilized 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 happen to come across any concerns regarding the gauge, kindly reach out to us immediately. Avoid leaving the management of your heating oil supply to luck or uncertainty.
