Everything You Need To Know About 1,000 Gallon Propane Tanks

Updated: Jan 30

You want to buy a propane tank but don't know how or where to start.

  • Do you need a 500-gallon propane tank or a 1,000-gallon propane tank?

  • Should you get an above-ground or underground tank?

  • Are there any special rules for installing propane tanks?

It can be confusing and overwhelming to figure out which propane tank is right for you, not to mention finding a reputable company that will install it safely and correctly.

No homeowner enjoys feeling ignorant about crucial pieces of their property. It’s challenging to make decisions, such as purchasing a propane tank, when you don’t know much about the issue. The longer you are stuck with indecision, the longer you go without the benefits of actually owning your own propane tank.

At Affordable Tanks, we believe you should be able to own your own propane tank and have the freedom to shop for fair propane pricing. This requires knowledge about the topic. Therefore, in this article, we are going to take a deep dive into everything you need to know about 1,000-gallon propane tanks.

Are you ready to learn about 1,000-gallon tanks?

Let’s dive in.

Should I get a 500 or 1000-gallon propane tank?

The place to start when deciding on which tank to purchase is figuring out what size of tank you will need.

A 500-gallon tank is best for homes that are under 3,500 square feet and use several propane appliances like a hot-water heater, a stove, a dryer, and a refrigerator. If your home is larger than 3,500 square feet, you may want to upgrade to the 1,000-gallon tank.

A 1,000-gallon tank is perfect for a larger square footage home. You can easily heat your entire building and run all your appliances off of a 1,000-gallon tank! These tanks are also great for smaller businesses looking to use propane for larger commercial and industrial appliances such as fryers, steam cookers, griddles, and convection ovens.

In short, you can answer this question yourself once you know the square footage of your building and how many appliances you will be looking to run in it.

How many gallons does a 1,000-gallon propane tank hold?

A 1,000-gallon propane tank is 16’2” long and 41” in diameter. It holds 800 gallons of propane when full.

For safety, propane tanks are never permitted to be filled with more than 80% total capacity. This is why a 1,000-gallon propane tank only holds 800 gallons of propane.

If you need more propane than 800 gallons, you will have to upgrade from a 1,000-gallon propane tank to a 2,000-gallon propane tank or get two 1,000-gallon propane tanks.

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

As you might assume, the answer to this question hinges on how much propane you use on a daily basis.

On average, a home furnace burns 500-1,200 gallons of propane a year while a hot water heater burns 200-300 gallons of propane per year.

Another way to calculate it is by factoring in the size of your home. A 1,000-gallon propane tank should last a 500-square-foot home for 847 days. It should last a 3,500-square-foot home 121 days.

What is a 1,000-gallon propane tank worth?

A 1,000-gallon propane tank costs anywhere from $1,500 to $3,000 to install above ground. This price nearly doubles if you wish to install it underground, ranging from $2,500 to $5,000. While underground tanks are more expensive, they do have some distinct advantages over above-ground tanks.

Several factors play into whether or not it is worth owning a 1,000-gallon propane tank. For instance, many propane suppliers will give you a better price on propane if you own your tank. Although you’ll have the upfront cost of the tank and installation, you won’t have monthly or yearly rental payments if you own your own.

Owning your own propane tank doesn't require any contracts. Plus, you’ll be able to compare prices on the tanks themselves and shop for the best deal instead of going with whatever tank the propane supplier gives.

Do 1,000-gallon propane tanks expire?

Another key question to ask yourself before investing in a 1,000-gallon propane tank is whether propane or its tanks ever expire.

Unlike fuel sources that can degrade over time (kerosene, diesel, gasoline), propane fuel has no expiration date, nor will its potency suffer while being stored. The only thing you need to worry about when storing propane is maintaining the health and integrity of the propane storage tank.

So while propane never expires, the tanks need to be properly maintained. A 1,000-gallon propane tank made of galvanized steel can typically last over 30 years when maintained properly.

To properly maintain your 1,000-gallon propane tank,

  1. Schedule regular propane deliveries

  2. Have the propane delivery company correct the volume during cooler times of the year

  3. Check for leaks

  4. Make sure the ground stays level

  5. Check for damaged or missing valves, controls, dials, or indicators

  6. Check for kinks in your gas line

  7. Check for corrosion on any of your equipment

  8. Check for accumulation of soot on the tank or any parts

When is the best time to use a 1,000-gallon propane tank?

It really boils down to how often you want to have your propane tank refilled.

If you own a home over 2,000 square feet, run a number of appliances off propane, and only want to refill it once a year, then you will likely want to have a 1,000-gallon propane tank.

And even if your home is not quite this big or you don’t have many appliances running off of propane, you may still wish to have a larger tank. This way you can purchase propane at a good price and more easily ride through the spikes in propane prices.


When you're looking at home heaters, propane is one of the most efficient and eco-friendly fuels. It's also safe!

And if you run other appliances off of propane, you will want to consider a larger propane tank.

"I would highly recommend Affordable Tank Services. They are an excellent family-run business. Their quote was very fair as I also got 3 other quotes. They even saved me $400.00 when they started to dig and my soil was such that I didn’t need stone dust and they canceled the delivery. We had a 1,000-gallon tank buried. Samuel was always calling to inform me of the time frame, and his son was on the job from start to finish. Excellent job. I would have them do any propane job I may have in the future."
