Propane Tank Sizes

Propane Tank Sizes

Before you buy your first propane heater it’s important that you familiarize yourself with everything propane. That includes the propane tank sizes, which vary in dimensions, capacity and weight.

Heating a standard sized family living room with a standard propane heater outputting 10,000 BTUs, for example, will require a much smaller propane tank than a heater outputting 40 000 BTUs to heat a office.

Dimensional Measurements of Propane Tank Sizes

Propane tanks come in all shapes and sizes and discovering the accurate measurements might be acquired through the tank manufacturer or propane sellers.

The propane underground fixing company will additionally give precise ground measurements before burrowing to fix the cylinders into the correct perspective with less labor. The following are the basic measurements of propane tanks and estimated holes measurements for the underground tank position.

Effective Selection of Propane Tank Sizes Vary a Lot

Tank selection is reasonably clear if you have the actual analysis of the amenities to use the Propane fuel.

  • One should first determine the Aggregate square footage of the homestead.
  • Propane apparatuses in the home to use the propane driven system

How Much Propane Does a Heater Consume?

If the heater is operating at full heat it is normal that 100,000 BTU will burn around 1 gallon per hour.

BTU / 100 000 = gallon per hour

Important: These dimensions will vary between manufacturers and tank types. Speak to your propane tank manufacturer before you make your purchase.

Propane has been rated as a fuel used in rural area, however with its economic benefits it’s progressively turning into an option of power in developed towns likewise. Propane heating has its special attributes making it effective compared with other heating solutions.

Before you think about propane system installations, there are several factors and considerations one has to put into perspective especially the Propane tank size, tank dimensions, and lastly the appliances to use with the system. Propane tanks can be used for domestic or industrial purposes.

Propane Tank Sizes and Weight – What You Need to Know

It is important to understand the different options and propane tank sizes. It can be a bit confusing for the beginner but it is actually quite simple. 

This first and most important concept to understand is what you need the propane tank for. Think about what you want to use the tank for, how often, and what power. This will help to determine the best option for your needs. 

You also need to consider the environment and the available space. In some circumstances, you might be forced to go for a smaller tank due to the available space. If you are going to use it often, it is better to go for a larger option. 

Here is a brief rundown on the most popular size options available:

20 lb tank

This is one of the smaller options for portable use and measures 18” tall and 12” in diameter. These tanks hold 5 gallons of propane. This makes them light and portable. They are easy to carry or transport and great for outdoor adventures or home use if you do not need too much power. 

The obvious downside is that these tanks will not last too long and need to be replaced, swopped out, or refilled regularly. Fortunately, a refill normally means a quick and easy exchange at your local refill station. 

33 lb tank

This is a popular choice for average home use as well as comping and travelers. The 33 lb tank measures 2 feet tall and 1 foot in diameter. These tanks carry 8 gallons of propane and are great for home or camping or traveling. They are a good compromise of size and capacity for most environments. 

Again, these normally require no waiting when you are needing a refill. They are simply exchanged at the outlet. 

100 lb tank

We are getting to the larger tanks now. These larger tanks are useful if you use a lot of propane. This will mean fewer replacements and reduce your cost in the long run. They stand 4 feet tall and 18” in diameter. The capacity is 25 gallons so this should keep most propane appliances running for a while.

They are not quite as light and compact as the 33lb tanks so you will probably need two people to move them. They are still relatively portable. They can be collected for a swop out but are generally delivered to your home. 

What many people do, if they use propane regularly, is to have two 100-lb tanks. You can fit a simple and affordable valve that will allow them to switch-over when the one runs empty. This will allow for an uninterpreted supply. Be sure to keep an eye on this so that you know when to fill the primary tank. There is an indicator light that shows red or green to advise you if the one tank has been depleted. 

420 lb tank

For serious propane uses a larger tank is necessary and the 420-lb tank is ideal. It stands 5 feet tall and is 10 feet long. The capacity is 400 gallons (at the standard 80% capacity). These tanks are generally filled on-site. They can be stored above or below ground. Note that these tanks are large and heavy so therefore not portable options. 

500 Gallon tank

Large tanks such as these are measured by the gallon. These tanks are generally 5 feet tall by 10 feet long. As they are filled to 80% capacity, they will hold only 400 gallons. This is a general safety standard. They can be positioned above or below ground and are refilled on-site. 

1,000 Gallon tank

Larger tanks are not measured by weight but by capacity. The 1 000 gallon tank is normally filled to 80% or 800 gallons. It is refilled on-site and can be stored above or below ground. These large tanks are generally used for commercial or industrial purposes but there is no reason a heavy propane user cannot use them domestically. 

You will sometimes come across different sizes or weights but these are the most common. 

What tank size do I need?

You need to consider your needs and equipment. What do you need to run on propane, how often, and at what level? These factors will help you determine the ideal size tank for your needs. Remember, you can always have two tanks. With the portable options, simply keep a spare. For larger tanks, installs a switch-over valve. 

Understanding the above explanation of sixes and weight should help you to determine the ideal tank size for your needs. Rather too much than too little and a spare or switch-over option is always a good idea. You do not want to run out of propane at a critical time. 

Understand the relationship and difference between dimensions, weight, and gallons. This is essential. You also need to consider your usage. For a single propane appliance, this is relatively simple. If you intend to run multiple propane products you will need to do a bit more homework. 

Understand how much propane they will use per hour according to the average setting that you use and do the sums. Once you have an idea of the basics it is fairly simple but the best knowledge will come from experience. This is, provided you keep track. 

When looking at propane tanks measured by weight, it is best to consider the gallons, as explained above. This will give you a better understanding of the tank capacity is make sit easier to compare options. 

Larger tanks are generally measured by gallons while smaller tanks are measured by weight. Understand the difference and what this means. It is often tricky to guess the amount of propane that remains in the tank. Some experience will help with this issue. A second or spare tank is always advisable.
