Why Isn’t My Propane Tank 100% Full?

propane tank napa, ca Are you a propane customer who has checked your propane tank’s levels right after your tank has been filled only to discover that it is not actually full? Maybe you were disappointed to find out that this was the case, but not filling a propane tank all the way is actually done intentionally.

A reliable and trustworthy propane supplier will never completely fill your propane tank as a safety precaution.

Propane is a liquid and liquids expand when they are heated. Propane actually expands faster than water does and it expands more than water does (we’re talking about 17 times more!).

Therefore, there needs to be extra space in a propane tank to allow for this expansion. Above ground propane tanks are usually filled to about 80%, which accounts for rising outdoor temperatures that heat and, in turn expand, propane. It’s safe to fill underground tanks a little more than 80% since the ground’s insulation provides protection against high temperatures.

The Right Propane Tank Size

Knowing that your propane tank should never be 100% full may influence your decision regarding the tank size you feel you need.

There are many different propane tank sizes and selecting one depends on the size of your home and the number of propane appliances you use. Here is a breakdown of the common residential sizes:

  • 20-pound to 100-pound propane cylinders: These tanks are generally used for grills, portable heaters, stoves and RVs.
  • 100-pound to 200-pound propane tanks: This size tank is recommended for houses that use propane appliances (with the exception of home heating systems that are powered by propane) and that use about 50 gallons of propane a month.
  • 325-gallon to 500-gallon propane tanks: If you power your home heating system with propane, use a number of other propane appliances throughout your home and your propane use totals about 100 to 200 gallons a month, this size range is appropriate.
  • 1,000-gallon propane tanks: Propane tanks that are this large are mostly used in industrial settings and by commercial businesses. Sometimes large homes that store propane for heating and generators use tanks of this size as well.
