What size propane tank do you need?

Tank sizes range from portable 20-lb. containers to tanks that can hold over 2,000 gallons. The size of your propane tank will depend on the size of your home as well as the number and size of appliances using propane.

Your geographical location and local climate can also play a role in choosing your propane tank size. For example, a tank for heating in milder climates may not need to be as big as a tank for heating in a colder climate. This guide can help you determine the right size tank for your needs and location.

Why Is It Important to Pick the Right Size Propane Tank?

This guide is devoted to helping you pick the right size propane tank. However, you may be wondering: why is it so important that I pick the right size?

The right size propane tank can help you save on your energy bills by controlling how often you need to fill it up.

While buying a tank that is too big isn’t too much of a disadvantage, buying a tank that is too small will affect your budget because you will need deliveries more often. Also, since you’re buying a smaller quantity of propane, the cost might be slightly higher.

Propane Tank Sizes

Before you can figure out what size tank you need, it’s important to know what sizes are available. Use our guide to figure out exactly which one of these you should buy for your particular home needs.

20 Pound Tanks

One of the most common residential propane tanks is the 20 lb. tank, which is the size of the tank you hook up to your propane gas grill or for other modest residential energy needs, like a fireplace.

20 lb. tanks are not used for home heating or anything else that a large scale, but the benefit is that you can purchase several tanks to have on hand for backup, and you can have them refilled at any propane retailer.

33 Pound Tanks

33 lb. propane tanks are relatively specialized. They are used almost exclusively to power certain vehicles, including forklifts, although they can fuel any vehicle that relies on autogas.

Because of the focus on powering vehicles, a 33 lb. propane tank may not be the best choice for most residential homes. However, people with farms or large tracts of land where you might need to use specialized vehicles may find such tanks very useful.

100 Pound Tanks

100 lb. tanks are a good choice if you have smaller appliances or heating devices that use propane. For instance, many people rely on 100 lb. propane tanks to power their gas cooking ranges, as well as their indoor fireplaces.

These tanks are obviously much larger than the 20 or 33 lb. tanks, but they are still small enough to be relatively portable.

Remember, the more items in your home that are fueled by propane, the more likely it is you will need a larger propane tank. Keep in mind that the bigger the tank, the stricter the local safety and installation regulations may be. You will want to keep tanks of this size at least three feet away from your house.

420 Pound or 100 Gallon Tanks

420 lb. tanks are large enough to be used for a variety of commercial purposes. However, these tanks can have many residential uses as well.

They work well as a heating solution for your home, for instance. They can also power emergency generators and are a great way to heat a swimming pool if you have one. If you intend to use your fireplace a lot, these tanks are also suitable for that purpose.

Just so you know, some homeowners and professionals refer to 420 lb. tanks as “100-gallon tanks” because that is how many gallons this size tank can hold.

500-Gallon Tanks

The 500-gallon tank is the most common size propane tank for residential propane use. It is often used for home heating, generator powering, cooking, pool heating, and more.

The primary benefit of this larger tank is that you can go that much longer without having to get it refilled. And when you are buying more gallons of propane, you can often get a slightly lower price rate for buying in bulk.

Typically, a home needs to be at least 2,500 square feet, and using propane for multiple appliances for a 500-gallon tank is the best choice. You can also choose above-ground or below-ground tank installation for 500-gallon tanks.

1,000-Gallon Tanks

Long story short about the 1,000-gallon tank? It does everything that the 500-gallon tank does, but it is twice as big.

That means this tank is also suitable for heating homes and pools and for powering generators. However, because this tank is so large, you should not buy it unless your home is at least 4,500 square feet.

1,000-gallon tanks are also popular for agricultural uses.

What’s the Verdict?

With all that being said, the question remains: what size residential propane tank do you actually need?

It all comes down to how large your house is and how many propane appliances you own. Smaller homes with fewer appliances need smaller tanks; larger homes with more appliances and items like heated pools are going to need much larger ones.

Important LPG Tank Information

The propane industry is educated about tanks, proper installation requirements, laws, and procedures governing the repair of tanks and systems they service. It is of the utmost importance that unlicensed individuals do not attempt to make repairs or modifications to their own tanks for safety and continued serviceability.

agriculture propane tanks for sale

Because the laws and safety practices change within the propane industry, tank installation and maintenance should only be performed by those who are familiar with these codes and regulations regarding LP Gas tanks. This cannot be stressed enough. DO NOT MOVE, REPAIR OR MODIFY ANY PART OF AN LP GAS TANK OR ANY PART OF THE GAS PIPING SYSTEM.

The information provided within this section is for consumer educational purposes only and is intended to better familiarize users with propane tanks and their parts. Portable tanks, known as bottles or cylinders are used as a fuel source for gas grills as well as forklifts. Stationary propane tanks are often found behind homes or businesses supplying all propane-fueled appliances in the structure. Stationary tanks are also used to refill cylinders and mobile containers at bottle plants.

Propane tanks, regardless of size, store propane liquid until it is used as either a liquid or vapor. All tanks are subject to rules based on safety for users, service technicians, and the general public and can only be filled to about 80% which constitutes a “full” tank of gas. Many people believe that propane tanks and butane tanks are the same but propane pressure is much higher than that of butane.

This means that while mostly identical in appearance and attached fittings, propane tanks are subject to higher pressures and the two types of tanks are in fact very different and cannot be filled with either of the two LP Gases. Propane tanks are for storing only propane. This section covers related subjects such as

    I must say, these guys have the best customer support. They sold me a propane gas tank and didn’t leave my place until I was completely satisfied with the placement and working of it. Gave me some real-deal advice about the safety and daily usage of it and told me that I could always call them in case of any issues. It’s the little things that count, and these guys nailed it.
