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 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.

Residential Propane Tanks: The Bottom Line

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.

commercial 500 gallon propane tanks at business

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

Your home’s heating system is essential to your family’s comfort and safety. While making a change can be daunting, switching your appliances and/or your entire home to propane is one of the best choices you can make. The switch from other sources of fuel to propane has gained wide popularity in recent years due to the many advantages that propane offers. Below you’ll find an outline of some of the biggest advantages a propane conversion has to offer, how it compares to other fuels, what the switching process looks like, and more!


Benefits Of Propane:
Did you know that switching to a propane heated home can raise your home value up to 4% according to the National Association of Home Builders? Check out the other benefits below:


Propane has an advantage over electricity when it comes to reliability. Electric heating can be dependent on the weather. This can be a problem if you live in an area where there are lots of thunder or ice storms. Weather storms can often cause tree branches to fall down bringing down the power lines. Without power, you have no way to heat your home. You have to sit without electricity or heating until the local maintenance crews are able to make the necessary repairs.

You can eliminate this headache by switching to propane as your heating source. Propane comes in stored tanks that work regardless of the weather. Furthermore, if you choose the regular autofill option, you will never have to worry about running out of propane or your heat getting shut down. Off Coast Propane Depot’s automatic delivery system uses innovative technology to calculate exactly when each customer is due for their propane refill.


Overly cold temperatures can be life-threatening so you do not want to risk being out of heat for too long. Propane’s reliability during any weather also makes it an extremely safe option for your home heating. Also, propane is a non-toxic and non-poisonous fuel making it a safe and healthy option for both the soil and groundwater. If you are located in an area where there are no gas lines, you can easily bury a propane tank underground. Propane tanks are safe to bury out of sight and will also not disrupt your outdoor environment or take up space.

Efficiency/Environmental Friendliness:

Propane is an extremely efficient and versatile fuel source. Propane furnaces typically have a 90% to 98% efficiency rating. Also, unlike oil, you can use propane to run your space heating, clothes dryer, water heating, appliances, backup power generators, and more. Using propane to heat all of these various home appliances will help you not only save on energy costs but also reduce emissions as well. Furthermore, using propane can help you save the earth because it does not use harmful greenhouse gases as other fuel sources might. In fact, the Clean Air Act of 1990 labeled propane a clean alternative fuel.

How To Switch From Your Old Fuel Source To Propane:
Most household items are designed so they can easily be switched to propane. Some of the most commonly used items that are switched to propane include hot water heaters, stoves, generators, furnaces, and outdoor living related items such as pools. Consider following the tips below when making the switch from another fuel source to propane.

Oil to Propane:
Switching from oil to propane involves contacting a trusted HVAC provider to perform the removal of your old heating system and the install of your new propane heating system. You will also need to have the oil tank removed from your property. After that, the new propane tank will be installed in your home. After the propane tank is installed, the tank should be connected to the propane line in your home. You just have to test the connection and your appliances will be ready for use! You’ll also want to cancel your service with the oil company so you don’t get charged unnecessary fees.

Natural Gas to Propane:
Switching from natural gas to propane involves removing gas lines and converting your appliances to propane. You will want to turn off the gas of the appliance. After that, disconnect the item from the natural gas line and remove the natural gas burners. Next, screw on the new burners (for propane) onto the burner valves. Finally, you can connect the device to your propane line and adjust your burner settings. Switching to propane from natural gas requires special gas utilization fittings. The manufacturer often includes these fittings in the instruction manual. If the propane fitting is not included or you can’t find it, contact the manufacturer. Additionally, you’ll need to cancel with your existing natural gas supplier.

Electric to Propane:

Whether converting your entire home’s heating system from electric to propane or just a few appliances such as a dryer or hot water heater, it’s the right choice. Removing an electric furnace, hot water heater, or anything else that runs on electricity, involves getting a quote from a trusted HVAC company. Once you’re ready to get started with propane, a trusted propane company like Off Coast Propane Depot can install propane lines and the right size tanks to fit your needs. The beauty about propane tanks is they come in all sizes. If you just need propane for one small appliance, propane can help! Also, propane water heaters can help you save costs in the long run because they cost less to operate and recover water faster than electric water heaters.

Best Time To Switch To Propane:

The best time to switch to propane is in the late Spring, Summer, or early Fall. You do not want to wait until winter to make the switch because propane is your source of heat during the Winter. The last thing you want is no source of heat during the coldest days of the year. The warmer months are the best time to schedule projects with HVAC companies and propane companies as their schedules are usually more open and they offer decreased rates for the “off-season.”

Switching to propane is very easy with the help of qualified professionals. You will also save lots of money in the long run since propane is efficient and helps save energy. For best results, call a qualified technician for help with appliance conversions and a full evaluation of your home before getting started.
