How Long Will My Heating Oil Delivery Last?

Understanding heating oil tank capacities and when it’s time to re-order fuel.

Every day, we’re getting closer to the chill and inclement weather of winter here in Martinsburg and throughout the Eastern Panhandle. Have you filled your heating oil tank yet to prepare for the cold months ahead? If this is your first year living in an oil-heated home, you may be wondering how long a tank of heating oil will last you.

The Roach Energy team is here to help. Here’s everything you need to know.

How Much Heating Oil Does a Tank Hold?

Most residential heating oil tanks have a standard capacity of 275 gallons, but it’s not quite as straightforward as that number implies. To allow for safe delivery and expansion of the oil, tanks are typically filled with about 240 gallons of heating oil.

What Factors Affect How Quickly You Use Heating Oil?

Several variables influence how fast your household will go through its heating oil supply:

• Outside Temperatures: Naturally, your home will use more fuel when the temperatures drop. On a mild 50° day, average consumption is about 2 gallons per day but on a frigid 15°F or lower day, it can spike to 8 gallons per day or more.
• Home Size: Larger homes require more oil to maintain a comfortable indoor temperature compared to smaller homes.
• Insulation Quality: A well-insulated home retains heat longer and requires less heating oil than one with poor insulation or drafty windows and doors.
• Thermostat Settings: The warmer you keep the house, the more oil you’ll burn, especially if you prefer coziness to layers of blankets.
• Time Spent at Home: Homes with occupants staying in all day (e.g., remote workers or extended families) will consume more oil than houses where people are out for most of the day.

How Long Will a Full 275-Gallon Tank Last?

Here’s a general breakdown based on typical usage patterns. Keep in mind, these are estimates and may vary based on the factors above:

• If your daily usage is 2 gallons/day (mild temperatures), a full 240 gallons could last up to 4 months.
• If you’re using 8 gallons/day (severe cold), your heating oil supply might only last about 30 days.
• For a typical-sized 2,000 sq. ft. home in winter, expect to use about one quarter of a tank per week or a full tank in 4–5 weeks.

To avoid running out of heating oil on an unexpectedly cold day, it’s always better to plan for refills before your tank gets below 1/4.
