Propane is a versatile fuel source homeowners and businesses can utilize for a variety of purposes. In order to take full advantage of its benefits and ensure safety, it’s important to select the proper propane tank size for your needs. Here is a guide to the four sizes and their applications to help you choose the right one. 

4 Sizes of Propane Tanks

1. 20-Pound

The most common and smallest available propane tank is 20 pounds. These hold just under five gallons of propane, ideal to power small appliances, such as bug catchers, gas grills, and patio heaters. They are conveniently easy to store and equally easy to transport when it’s time to exchange or refill them. 

2. 100-Pound

The next step up is a 100-gallon propane tank, which can hold up to 25 gallons of fuel. These are about four feet high and work well for larger portable appliances, such as barbecues and gas cooking ranges.

They’re ideal for families who cook outside often or need propane to power a major appliance such as a clothes dryer or fireplace. Just be sure to place these at least three feet from doors and windows and at least five feet from anything combustible. 

3. 420-Pound

For more significant applications, such as heating a small house or pool, a 420-pound tank may be a good option. These hold up to 100 gallons when filled to at least 80% capacity. This model is also useful for heating hot water in a home or for powering a large generator. For safety, place it at least five feet from doors or windows and at least 10 feet from combustible materials. 

4. 500 Gallons

If you need to power your home or business, a 500-gallon propane tank may be the one for you. These hold up to 400 gallons of propane at 80% capacity.

The 80% maximum capacity rule is necessary because fuel expands when heated and needs sufficient space to accommodate that change. A technician can install these above or below ground, but they must be placed at least 10 feet away from the building in either case.
