How long does a 1,000 gallon propane tank last? (calculated)


A 1,000 gallon propane tank is one of the largest propane tanks for a home. For an average American family, this is a perfectly sized propane tank if you don’t want to refill it during the hot winter weather. Here are some frequently asked questions about 1,000 gallon residential tanks:

How long will a 1,000 gallon propane tank last?

Obviously, it mainly depends on how much propane you burn per day, week, month. Here’s the wide range answer: A 1,000-gallon propane tank will run anywhere between 2 months and 11 days To 2 years and 4 months (847 days, to be exact).

To estimate how long a 1,000 gallon propane tank lasts for your home, we only need these two metrics:

  • 1,000-gallon propane tank, when full, contains 800 gallons of propane, This is an 80% security measure; You never fill 1,000 gallons of propane in a 1,000 gallon propane tank.
  • How much propane do you use per heating season (6 cold months; from October to March). Using data provided by Statista (the article describes how long propane tanks last), an average American household (2,200 square feet) will burn about 750 gallons of propane during the heating season. how much propane do we need to heat in winter

Keep in mind, this is the average consumption. Actual propane consumption can vary greatly, as explained by the Department of Housing and Urban Development (HUD): “An average-sized modern home in a warm climate area using high-efficiency propane heating equipment and other appliances can expect to use 194 to 258 gallons per year, while the same home in a colder climate zone typically uses 991 gallons per year.” will use up to 1,844 gallons per year.

For all intents and purposes, we’ll use 750 gallons of propane for 2,200 square feet for an average of 6 cold months. Based on this, we can calculate how long a 1,000 gallon propane tank will last (on average) for any given home size.

How long does a 1,000 gallon propane tank last for a home?

Quick example: If you have an average home of 2,200 square feet, you’ll burn about 750 gallons of propane over the course of 6 heating months. This means that a 1,000 gallon propane tank (which holds 800 gallons of propane) will last the entire heating season.

How long will a 1,000 gallon tank last for a small home, such as 1,000 square feet? Or a large house, say 4,000 square feet?

Using averages, we can estimate neatly how many months and days a 1,000-gallon propane tank will last.

We will look at another example to illustrate how this calculation is done. In addition, you’ll find a table showing how long a 1,000-gallon propane tank should last for average homes with square footage between 500 square feet and 4,000 square feet.

Example: 3,000 square foot house

Let’s say we have a 3,000 square foot home and you use propane-powered heating. Using the average above, we know that we use approximately 0.341 gallons of propane to heat 1 square foot for 6 months (180 days).

Here we can calculate how much propane we need for the entire 6-month long heating season for an average 3,000-square-foot home:

total propane needed = 3,000 square feet × 0.341 gallons / square foot = 1,023 gallons

We will need a total of 1,023 gallons of propane. This means we are burning 5.68 gallons of propane per day.

Now, we have a 1,000 gallon propane tank with 800 gallons of propane. We can calculate how long our propane tank will last:

1,000-gallon tank to last = 800 gallons / 5.68 gallons / day = 141 days = 4 months and 21 days

This is the basic idea of ​​how you can calculate how long a 1,000 gallon propane tank will last for any given home size. Here you can see the calculations done for different house sizes:

1,000-Gallon Propane Task Longevity for Different House Sizes (Calculated Table)

House Size (Sq. Feet): Lasts for a 1,000-gallon tank:
500 square feet 2 years and 4 months
1,000 square feet 1 year and 2 months
1,500 square feet 9 months and 12 days
2,000 square feet 7 months and 2 days
2,500 square feet 5 months and 19 days
3,000 square feet 4 months and 21 days
3,500 square feet 4 months and 1 day
4,000 square feet 3 months and 16 days

Hopefully, with these calculations, you’ll have a better understanding of how long a 1,000 gallon propane tank should last. For a similar calculation, you can also check the numbers for other propane tank sizes, such as:
