However, numerous types of gas appliances connected to your propane tank affect the lifespan of the propane tank. Suppose you only use it for a single device, like a grill. In that case, it will last longer compared to situations where you're powering multiple appliances simultaneously.

  1. Temperature and Climate:

Climate conditions can impact a propane tank's lifespan. Extreme cold temperatures can cause the pressure inside the tank to drop, decreasing propane flow and indicating that the tank is empty sooner. On the other hand, extremely high temperatures might increase pressure inside the tank, affecting its safety.

  1. Tank Age:

How long does a 1lb propane tank last? Well, small Propane tanks have an expiration date of 12 years from their manufacturing date. Once those 12 years are up, you can exchange the tank for a new one or subject it to inspection for requalification, enabling an additional five years of usage. The age of the tank can impact its overall functioning. Older tanks might have corrosion or damage that may affect their safety and efficiency. 

  1. Proper Storage:

It is crucial to store your propane tank appropriately. Direct sunlight and excessive temperatures should be avoided because they can cause pressure changes and damage the tank. Also, tanks should be stored in a well-ventilated environment, away from potential fire explosions.

  1. Tank Quality:

The quality of a propane tank plays an essential role in its performance and longevity. High-quality propane tanks are less likely to have leaks, rust, or damage and, therefore, last longer. Furthermore, high-quality tanks are built using durable materials. They are subjected to severe quality control stages during the manufacturing process.

  1. Safety Measures:

Following safety guidelines is essential for different types of gas fire pits. Regular inspections and maintenance can help identify and address potential issues before they affect the tank's lifespan.

  1. Tank Size:

The size of the propane tank is one of the most significant factors impacting how long a 20lb propane tank lasts. Smaller tanks, like the 1 lb commonly used for portable grills, will have a shorter lifespan than larger tanks, such as the 20lb used for home grills and fire pits. Remember, the more propane gas the tank can hold, the longer it will last.

How to Calculate the Number of Hours a Tank Will Last

Step 1: Identify the Total BTU Rating:

  • Check the BTU ratings of your propane appliances.
  • Add up the BTU ratings of all the appliances or devices you plan to utilize with the tank.

Step 2: Check the Propane Tank Capacity:

  • Find out the propane tank's capacity, generally specified in either pounds or gallons.
  • This information is generally labeled on the tank or its documentation.

Step 3: Calculate the Total BTU Capacity:

  • Multiply the tank's capacity by the BTU value equivalent of one pound or one gallon of propane fuel.
  • The BTU value of propane tanks is approximately 91,547 BTUs per gallon or 21,594 BTUs per pound.

Step-4: Determine the Hourly Burn Rate:

  • Divide the tank's total BTU capacity by your appliances' total BTU rating.
  • This calculation will estimate the number of hours the propane tank will last.

Tips for Propane Tank Maintenance

Here are some simple propane tank maintenance tips:
