How Long Will My Propane Supply Last?

Tank Size and Usage Make All the Difference

When it comes to propane supply, it’s simple math: A larger tank holds more propane, and more propane lasts longer. Unlike other fuels, propane doesn’t degrade or spoil over time, so there’s no risk in storing more than you immediately need. Still, that doesn’t mean you should install the biggest tank available just to avoid runouts. There are smarter ways to make sure your home always has the propane it needs.

Our customers enjoy the convenience of automatic delivery, which takes the guesswork out of scheduling refills and prevents the worry of running out. But if you notice that you’re getting deliveries more often than every six weeks, the issue may not be usage alone—it could be that your tank size isn’t the right fit.

How Are You Using Propane?

How long your propane supply will last depends largely on how many appliances you’re running. For light use—say, just a stove or water heater—a 500-gallon tank of propane could last well over a year. But if propane fuels your home’s heating system, hot water, and multiple appliances, you’ll likely need a refill every six to eight weeks. According to the U.S. Energy Information Administration, the average American home consumes about 750 gallons of propane each winter for heating, cooking, and water heating.

It’s also helpful to know how much fuel different appliances burn. For example:

• A propane cooking range uses only about 35 gallons a year. If that’s your only appliance, a 500-gallon tank could last more than a decade!
• A propane fireplace consumes about 200 gallons annually.
• A traditional water heater burns about 1.5 gallons a day, or roughly 200–300 gallons per year. A tankless model uses 0.5–2 gallons per running hour, depending on how much hot water you’re using.
• Pool heaters are on the higher end of the spectrum since they heat a large volume of water.

Your household size and the efficiency of your equipment also make a big difference. A family of five will use much more hot water—and propane—than a couple living alone.

When the Power Goes Out

One of propane’s greatest advantages is its versatility. Many homeowners rely on it to fuel standby generators, which automatically kick in when storms or outages hit. A 5,000-watt generator can run continuously for 7 to 10 days on a 500-gallon tank, keeping your home safe and comfortable until the power returns.

The Bottom Line

Residential propane tanks typically range between 120 and 500 gallons, and the right size for your home depends on how much you use. A larger tank means fewer refills and more flexibility when prices rise. But bigger tanks also require more installation space—either underground or above ground, where they can affect curb appeal.

The good news is that you don’t have to figure it out yourself. The pros at Rand Wade can evaluate your home’s propane needs, recommend the right tank size, and set you up with automatic delivery for total peace of mind.
