Portable LP storage tanks are small enough that they can be hand-carried to install on items for use. The smallest is the standard 465gr cylinder that you screw onto a camp stove for cooking. A 10-pound size is portable for hikers and backpackers to use for portable grills and heaters for their tents. Gas BBQ grills at home use 20-pound tanks that are exchangeable when empty for a full tank. Forklifts generally use a 33-pound tank for their fuel source. Recreational Vehicles (RVs) use portable LP storage tanks in a larger size of 5 1/2 to 11.2 gallon sizes.


75-gallon tanks are in use in manufacturing and the welding industry for welding and fabrication shops and other businesses that use LP gas to operate. These tanks are semi-portable because they are too heavy to move by hand and can attach to a specific dolly that accommodates their size and shape to be mobile. A business will return these types of tanks when they are empty and the company purchases a full replacement tank from their local propane company.


Many homeowners have gas appliances such as stoves, heating systems and hot water heaters. There are several sizes to choose from in a home LP storage tank. The standard sizes are 100 gallon, 250 gallon and 500 gallon tanks. LP gas companies usually have a minimum order that is required to fill a residential tank and sometimes charge a trip charge. It is beneficial to estimate the amount of gas that you use per year and purchase a tank that will require filling less often.


The largest tanks are purchased by commercial businesses that can range from restaurants with gas stoves to industrial plants, which consume much higher volumes of LP gas. These storage tanks may be above ground as a residential tank normally is or they may be permanently underground. Underground tanks are identical to above ground but have all of their fittings on the top of the tank for easy access. These large storage tanks can range anywhere in size from 6,000 gallons to 90,000 gallons.
