A 100 lb propane tank has about 2.16 BTUs (British Thermal Unit). Because of that, a 100 lb propane tank can last months, depending on how you use it. For example, a 1500 watt electric heater takes 5000 BTUs per hour. You do this by taking the standard unit conversation number (3.41) and multiplying it times the number of watts.

Next, please take the 5000 and put it into 2.16 million, and you get 432 hours, which you divide by 24 to get 18 days of continuous heating. As a result, you can see why it is more appropriate to have a 500 or 1000 gallon tank for your home.

It is not safe to transport a 100-pound propane tank on its side because it can shift and cause damage during travel. Common problems include pressure relief valve damage which can cause your propane tank to potentially leak and work improperly.

Use rope, twice, cables, or ratchet straps to secure your propane tank so that it doesn’t move during travel. A 100-pound propane tank that is filled with gas can weigh an extra 90-100 pounds or more, so it is important to fasten it as securely as possible.

For home use, propane tanks range in size from portable 20-pound containers to tanks that can house more than 2,000 gallons. The size of propane tank that you need will depend on the size of your home and the number and size of appliances that are fueled by the propane.

Though, your local climate and geographical location can also determine your propane tank size. For instance, you may not need as big of a tank for heating in a milder climate than you would in a cold climate.

The following are the most common propane tank sizes, along with their dimensions, capacity, uses, and placement. Though, keep in mind that propane tanks are only filled to 80% capacity in order to allow safe expansion of the propane. So, even when your propane tank is full, the gauge will only display 80%.
