A 500-gallon propane tank is a popular choice for homes and businesses that need a reliable energy source. It holds enough propane to power appliances, heating systems, and more for an extended period. But how long does a 500-gallon propane tank last? The answer depends on several factors: usage, efficiency, and seasonal changes. Understanding propane consumption and proper maintenance can help maximize its lifespan.
How Much Propane Can a 500-gallon Propane Tank Hold?
A 500-gallon propane tank can hold about 400 gallons of propane when filled to 80% capacity. This safety margin is best to avoid overfilling the tank and allow the gas to expand safely. The tank is large enough to meet the energy needs of most households and businesses for months at a time.
These tanks measure about 9 feet long and 3 feet wide. They weigh around 950 pounds when empty, but when full, they can exceed 2,500 pounds. Because of their size, professional installation and maintenance are necessary to ensure safety and efficiency. Understanding these details helps you make better decisions about placement and upkeep.
The size of this tank makes it a good investment.
How Long Will a 500-gallon Propane Tank Last?
The lifespan of a 500-gallon propane tank depends on how much propane is used daily. Home heating systems, water heaters, gas stoves, fireplaces, and other propane-powered appliances contribute to consumption. For example, a propane furnace running six hours daily can use up to 180 gallons a month, while a gas stove may use only 5-10 gallons per month. A propane generator can consume 2 to 3 gallons per hour, making it a significant factor in propane depletion.
A home using propane for heating, cooking, and water heating can expect a 500-gallon tank to last between two and six months, depending on the season and energy efficiency. Households that use additional propane-powered appliances, such as fireplaces and pool heaters, may need refills more frequently. Home heating systems, water heaters, gas stoves, fireplaces, and other propane-powered appliances contribute to consumption.

How to Make a 500-gallon Propane Tank Last Longer
To extend the lifespan of a propane supply, upgrade to energy-efficient appliances, and improve home insulation to reduce heating demands. Also, scheduling regular propane maintenance ensures that appliances and the propane tank function optimally. You should install a propane tank gauge to help track consumption, and a programmable thermostat can prevent unnecessary fuel usage during colder months. Some homeowners also consider using alternative heating sources, such as electric space heaters, to conserve propane.
How to Know When It’s Time for a Refill
You should refill your propane tank before it gets too low to avoid interruptions in use. Many homeowners schedule refills when the tank level reaches 20-30%. You know that you need a refill when you see this:
- Weak Flame on Appliances – If the flame on a gas stove or water heater is weaker than usual, the propane supply may be running low.
- Difficulty Starting Propane Appliances – If appliances take longer to ignite, it may be time for a refill.
- Propane Gauge Reading – Regularly checking the propane tank gauge helps prevent unexpected shortages.
Signing up for propane delivery ensures you have a consistent supply without the stress of checking levels frequently. Some delivery services offer automatic refills based on estimated usage.
How Much Does a 500-gallon Propane Tank Cost?
The cost of a 500-gallon propane tank varies depending on location, brand, and installation requirements. First, you buy the tank, then installation and any necessary permits. Additional costs may arise for underground installation, trenching, and safety features.

How often should a 500-gallon propane tank be inspected?
Routine inspections should be conducted annually to check for leaks, rust, and proper functionality. A professional propane provider can help with this. Remember that regular maintenance helps extend the lifespan of your tank and improve its efficiency.
Can a 500-gallon propane tank be installed underground?
These tanks can be installed above ground or underground. Even though underground installation requires additional preparation, it keeps the tank hidden and protected. This option is ideal for homeowners who prefer a cleaner aesthetic and want to free up space in their yards. However, underground tanks require corrosion protection and periodic inspections to ensure long-term durability and safety.
How do I know if my propane tank is running low?
Most propane tanks have a gauge that displays the current propane level. To avoid running out, it is best to refill before reaching 20-30%.
What happens if I run out of propane?
If a propane tank runs empty, the system will require a safety inspection before refilling. Running out of propane can also cause damage to appliances, so it’s best to schedule regular deliveries.
How do I properly maintain my propane tank?
Regular maintenance includes checking for leaks, monitoring the propane gauge, and keeping the area around the tank clear of debris. Scheduling professional inspections ensures safe operation.
