When To Change Propane Tank?

A bottle is certified for 12 years in the United States and 10 years in Canada from the date of manufacture. Depending on the manner and kind of recertification, a recertified tank is good for 5, 7, or 12 years.

How do you tell when it’s time to replace your propane tank?

More than 10% of American houses, believe it or not, use propane to power their furnaces and other appliances. And the number of people who use propane to power their grills is far higher.

Keeping a continuous supply of propane on hand is essential for such homeowners to keep their homes pleasant and their appliances running properly.

However, how can you know when your tanks are running low? It’s not as difficult as you may believe.

Keep an eye out for these indicators that it’s time to refill your household and barbecue propane tanks.

When a propane tank is empty, how can you tell?

We’re in the midst of outdoor living season in Connecticut, which means it’s time to fire up your propane BBQ grill! Simply ensure that you have extra gas for your next summer BBQ.

However, as any veteran propane griller knows, most 20-pound propane barbecue cylinders lack a gauge, which means you’ll need to figure out how much fuel is left in your tank in another method.

Here are three easy ideas to get you started:

1. Make use of warm water. This safe and straightforward method for determining how much propane is left in your tank was given by the FiX IT Home Improvement Channel. To accomplish this,

  • Fill a small bucket halfway with warm to hot tap water and set aside.
  • Pour the water down the tank’s side.
  • Feel for a cool location around the tank’s side using your hand.

The fill level of the tank is at the top of the cold spot (it’s cool because liquid propane inside the tank absorbs heat from the water, making the tank’s metal wall cool to the touch).

2. Check the tank’s weight. On the handle of most propane grill tanks are two numbers: the water capacity (“WC”) and the tare weight (TW), which is the weight of the tank when it is empty. When empty, most grilling tanks weigh around 17 pounds and store around 20 pounds of gas.

Simply weigh your tank on a scale and subtract the TW number to find out how much propane is left in it. If a 27-pound tank has a TW of 17 pounds, there’s about 10 pounds of gas left, or little more than half a tank.

3. Install a gauge on the outside of the building. Options for external propane tank gauges include:

  • Installed between the gas line from the grill and the tank’s cut-off valve, inline pressure gauges measure pressures to determine how full the tank is.
  • Analog propane scales resemble luggage scales and are pre-programmed to account for your tank’s TW.
  • A digital display of remaining cook time and gas fill percentage is provided by digital propane tank scales. Some even have apps for smart phones.

Choose a gauge that you like (they’re available at your local hardware shop and on Amazon) and try it out!

Don’t let your propane cylinder burn you.

Before your next summer party, use these ways to figure out how much gas is left in your tank. Don’t panic if you run out of propane; simply visit one of our Connecticut showrooms for a propane cylinder refill!

When should my 20-pound propane tank be replaced?

Your propane tank has an expiration date that you may not be aware of. It’s between 10 and 12 years old, according to the year of production on the tank’s handle near the tare weight. This is dependent on the laws in your area. Tanks can be re-qualified by competent professionals, which extends the life of the tank by around five years before it needs to be re-qualified.


Residual propane will be found in old/empty propane tanks, which must be disposed of at hazardous waste disposal sites.


As previously stated, 20-pound propane tanks are used for small chores such as cooking single meals. If you’re grilling on a medium-sized barbecue, one tank of propane will normally last between 18 and 20 hours. Larger barbecues, on the other hand, can consume 20 pounds of propane in as little as 10 hours.

If you use a medium-sized grill on high heat, you’ll need one or two pounds of fuel per meal on average. That works out to about 8 grilling sessions per tank.


The industry standard for measuring the heating efficiency of domestic equipment is the British Thermal Unit, or BTUs. One gallon of propane equals 92,000 BTUs, and the average house furnace uses 100,000 BTUs. The average house furnace consumes about one gallon of propane each hour.

Depending on how often you turn on your furnace, a house furnace might burn anywhere from 500 to 1,200 gallons of propane every year.

Hot Water Heaters

The amount of hot water you use depends on how many bathrooms you have and how many people are in and out of your home. The average residence uses approximately 1.5 gallons of propane per day for conventional hot water heating.

For hot water, the average homeowner will use between 200 and 300 gallons of propane each year.

The average homeowner will consume about 2.5, 500-gallon propane tanks for house heating and cooking each year.

What is the average lifespan of a propane tank?

How long do propane tanks last? A bottle is certified for 12 years in the United States and 10 years in Canada from the date of manufacture. Depending on the manner and kind of recertification, a recertified tank is good for 5, 7, or 12 years.

What is the average lifespan of a propane tank?

The propane tank is the heart of your propane-powered home, pumping propane gas to appliances that will keep your family warm all year and make your home more enjoyable and comfortable.

But, honestly, how much do you know about propane tanks? To get you started, here are three key questions and answers.

1. How long is a propane tank supposed to last? Propane tanks are built to last: a high-quality, properly maintained galvanized aboveground propane tank or propane cylinder should last 30 years or more on average, with some aluminum and composite cylinders lasting even longer. The size and use of the propane tank, as well as how well it has been cared for, play a large role in its lifetime. For example, underground propane tanks have a reduced average life expectancy of 20 to 30 years, depending on the soil type and whether or not the tank was installed properly.

2. What size propane tank do I require? Gas tanks are available in a variety of sizes; the right size for your Connecticut house is determined by the type of propane appliances and equipment you plan to use. The following are some of the most common propane tank sizes, as well as some of the equipment that they typically power:

  • 56 gallon capacity Ovens, stovetops, and laundry dryers (holds 48 gallons of propane)
  • 120 gallon capacity
  • Water heaters, space heaters, and pool heaters are all examples of heaters (holds 100 gallons of propane)
  • 250-gallon capacity
  • Generators, pool heaters, and a combination of equipment are all available (holds 200 gallons of propane)
  • 500-gallon capacity
  • Heaters for central heating and swimming pools (holds 400 gallons of propane)
  • 1000 gallon capacity
  • For use in large homes and businesses (holds 850 gallons of propane)

3. What are some of the propane tank placement guidelines and regulations? Federal, state, and municipal laws govern the location of propane tanks, which must be followed at all times. Here are a few of the most significant:

Propane tanks with a capacity of less than 125 gallons of water:

  • A window air conditioner must be at least 10 feet away.
  • A minimum of 5 feet from a crawl space opening is required.

Propane tanks with a water volume of 125-500 gallons:

  • A minimum of 10 feet from a building is required.
  • A line of neighbouring property must be at least 10 feet away.

Propane tanks with a capacity of up to 2000 gallons of water:

  • must be set back at least 25 feet from the building
  • A portion of an underground tank of this size must be at least 10 feet from a building or property line.

Is it possible to store propane tanks outside during the winter?

Propane tanks can be safely stored outside, but it’s important to find a location that’s not too close to your home. It’s crucial to remember that freezing temperatures aren’t a concern for propane tanks while storing them in the winter. In fact, when storing your tank outside in the winter, you don’t even need to cover it.

Place the tank on a solid surface, such as a piece of wood or a slab of concrete, and store it open or closed.

It’s also simple to store propane tanks during the summer. During the summer, your propane tank can be kept outside on a flat, firm surface. Keep the tank in a shady spot so it doesn’t sit in direct sunlight for long periods of time. This will keep the tank at a safe temperature, but not above 120 degrees Fahrenheit (49 C).

Do Coleman propane tanks have a shelf life?

Yes. The expiration date is written on every Coleman propane tank. The tank has a shelf life of up to 7 years provided it is not opened. The gas should be utilized within two years of opening it before you need to vent and replenish it.

Is it true that Blue Rhino accepts used tanks?

However, certain propane exchange firms, such as Blue Rhino, will gladly accept and recycle your unused propane cylinders at no cost to you. If you don’t want your propane tank, simply set it next to a Blue Rhino exhibit and we’ll take care of the rest.
