Tank Information

Everything you always wanted to know about propane tanks but were too afraid to ask!

The propane industry is a bit mysterious in that there is more than one way to describe a propane tank or cylinder.

Note: Your tank must have a yellow cap as pictured here for us to fill your tank.​

D.O.T. (Department of Transportation) certified propane receptacles are called CYLINDERS.

These are named by Pounds of propane held. Propane weighs 4.2 lbs. per gallon.

(Pictured: Left–’Hundred Pounder‘, Right–’420 Pounder‘)

A.S.M.E. (American Society of Mechanical Engineers) certified propane receptacles are called TANKS.

These are named in Gallons held [Ex. 120, 500, etc.] It should be noted that propane can only be filled in a tank to 80% capacity. So a 120 gallon tank is more often referred to (in regard to its maximum capacity for propane) as a ‘100 Gallon Tank‘
(pictured on right), and a 500 Gallon tank (not pictured) can only hold about 400 gallons when full.

New Installation: How Do I Choose The Right Tank Size?

Tanks range in size from 120 gallons to 1000 gallons. They are built for above-ground and underground applications.​

Above Ground tanks are set according to local laws and regulations on the ground near your home/office and away from any sources of ignition. They are usually painted white, aluminum, or some other light reflecting color for safety reasons. Above-ground tanks are ideal for consumers in mountainous areas, where burial is not possible, and those with a satisfactory place in their yard for installation. The greater percentages of tanks are installed above-ground. These tanks are also more accessible by your propane dealer for filling and maintenance. You can lease or purchase this type of tank.​

You may find that you cannot select a practical or attractive location for setting your tank in the home or office landscape. Underground tanks are designed to be buried in the ground and are completely out of sight except for the dome covering the valves for servicing the tank.

Underground tanks have a tough chemical and water resistant coating applied at the factory—a hard, baked on polyurethane finish. This factory-applied coating is designed to be the final coating for the tank prior to its burial in the ground, provided the tank has an intact and continuous external coating at the time of burial. We thoroughly inspect the tank to determine whether the factory applied protective coating is intact and continuous.

tanks-above-groundUnderground tanks also have an anode bracket to provide additional anode protection against corrosion. Coatings alone may not protect a buried tank against corrosion. Even after thorough inspection and touchup, the tanks can still get scratched and gouged during handling, setting, backfilling and settling. As a result the coating can have small imperfections here and there. Corrosion pitting rates are greater at these flaws, scratches and gaps in the coating than they are on completely bare tanks. Therefore, we use cathodic protection to help protect the steel tank wherever it may be exposed.o.

This type of installation is so involved, you will be required to purchase this type of tank up front.

There are several things that you should consider when deciding which propane tank is right for you. For instance, are you heating a storage room or a warehouse? Do you have space in your yard for the tank or must it be buried underground? Determining your needs is as easy as 1-2-3…


Propane tanks are always placed on site. Although certain state laws and regulations must be followed, general tank designs allow for some flexibility in where tanks are installed. As you read above, there are certain benefits to each type of setting.


Often times, the most difficult decision is choosing the approximate size tank your need. This should be calculated by your propane supplier. However, we will need to know the actual propane load of your system. By calculating this in advance, the job will be made easier.

Determining the actual propane load will provide a more specific estimate of your tank needs. The total load is the sum of all gas usage in your home or building. It is arrived at by adding up the BTU input of all gas appliances in the installation. The BTU input may be obtained from the nameplate on the appliance or from the manufacturer’s literature. Future appliances which may be installed should also be considered when planning the initial installation to eliminate the need for later revision of piping and tank size. Call ‘The Propane Specialists’ at Affordable Propane to help you with these determinations.
