How Long does a 13kg Gas Bottle Last?

When cooking on your BBQ, you may wonder how long a 13kg gas bottle will last. Depending on the burner’s usage and type, this gas bottle can last anywhere from 10 to 244 days. Typically, a 13kg bottle can last around 10 hours of cooking, which is plenty of time. However, it would help to replace the gas cylinder when it is cold to avoid burning your fingers. The energy content of a 13kg gas bottle is 600 MJ. The amount of energy used depends on the type of burner on your BBQ.


In addition, you should also keep in mind the type of gas grill you are using. Tabletop gas grills, for example, usually have one burner and therefore don’t consume as much energy. Depending on the type and strength of use, a 13kg gas bottle can last for ten to eighty hours or even weeks. However, if you are using two or more burners, you should expect a 13kg gas bottle to last between 40 and sixty hours, depending on the type of grill.

Gass Bottle

Do you know what “bottle gas” is? An old phrase. This term’s actual antiquity or place of origin is unknown, but we are certain of its meaning.

Chemicals kept under pressure in a gaseous condition are called bottle gas. Naturally occurring in association with other hydrocarbons, bottled gas is a versatile substance that is separated and liquefied through pressurization and kept in a gas bottle or cylinder (pressure vessels). Products like propane, butane, or a combination are considered bottle gases.

This flammable hydrocarbon material, which is gaseous at zero degrees, is created by the volatile distillation process used in petroleum and oil refining to separate the bottled gas from the crude oil using a distillation tower. The gas is then stored in a container after being distilled at standard temperature and pressure. Bottle gas is a word that dates back to a time when these vessels were known as bottles. Today, propane is delivered to your home or business in cylinders and tanks or stored in liquid form on railcars, ships, and vehicles.

“Bottled gas” has over a hundred applications worldwide. Among the many uses for “bottle gas,” or propane as we commonly refer it, are auto fuel, grills, propellants, boats, heating, cooking, camping, and water heating. Irrigation pumps, greenhouses, forklifts, and backup generators are a few further applications for the medical and agricultural sectors.

How Long does a 13kg Gas Bottle Last?

Depending on the size of the burner and the amount of use, a 13-kilogram cooking gas bottle can last anywhere between 8 and 74 days. The gas bottle lasts eight days when used with a large 15MJ wok-style burner for 90 minutes daily. A modest 5MJ burner used for 30 minutes daily will consume the gas bottle in 74 days.

Depending on the size of the burner and the amount of use, a 13-kilogram cooking gas bottle might last between 37 and 12.4 hours. This gas bottle estimation is predicated on the burner being set to its highest. Lower settings will extend the life of the gas bottle.

About 185 MJ of energy is included in a 13-kilogram cooking gas bottle. Divide the 185MJ by the burner size to determine how long your cooking gas bottle will last. You must add their combined MJ ratings before dividing if you’re using multiple burners.

How do I Know if My Cylinder is Empty?

Weighing the gas bottle is an excellent approach to determine how much gas is left if you notice that it feels a little lighter than you’d like. The empty weight of most bottles is stamped on the neck, and if your bottle weighs the same as the weight shown on the stamp, you’re out of gas. The remaining gas can then roughly be calculated using the weight differential.

How to Save Cooking Gas?

Cooking on a gas stove is quick and simple, but if you use too much gas, it could cost you when it comes time to pay the utility bill. Fortunately, you may take a few easy steps to save household expenses. You can improve the efficiency of the heat produced by your gas stove by switching to high-efficiency cookware, such as pressure cookers and thermal bags. Cover the flame fully while it is heating up by using flat-bottomed, reflecting cookware in good condition.

Reduce the Heat as Much as Possible

When they need to heat anything, some cooks have a nasty tendency to turn the burner up. Instead, make an effort to use as much heat as is required to reheat or cook your food fully. Anything above the bare minimum needed temperature will be useless.

  • Water, for example, boils at 212 °F (100 °C). Once it’s boiling, leaving the cooktop on full blast won’t make it any hotter—it will only use up more gas.
  • When cooking from a recipe, always follow the instructions to a T. Most recipes specify what level of heat to use (“low,” “medium,” “medium-high,” “high,” etc.).

Make Sure the Pot or Pan is Covering the Flames Completely

The heat is set too high if you can see the flames licking the sides of the pan. Reduce the heat until the flames are contained to the pan’s bottom surface. They will otherwise release heat into the surroundings.

  • For best results, only use flat-bottomed cookware. The entire heating surface will always remain in contact with the flames with these pieces.
  • If your stove has multiple burners of different sizes, choose a burner smaller than the pot or pan you’re using to ensure that it’s not putting off excess heat.

Keep your Stove’s Burners Clean to Ensure that they’re Working Properly.

Make sure your burners are off and cool to the touch before cleaning them. After that, remove the safety grates and use a moist paper towel to clear any remaining residue. Finally, use soapy water to scrub the burners’ area to remove all residue thoroughly.

  • The flames emitted by your gas stove should burn a bright blue color. Yellow or orange flames could be a sign of incomplete combustion, which means that the gas in the lines isn’t being used to its full potential.
  • If cleaning the burners doesn’t solve the problem, call a repairer to look at them and replace them if necessary.
  • A weak burner isn’t just irritating; it’s dangerous—incomplete combustion can release hazardous carbon monoxide gas.

Check for Potential Leaks

Even while you are not cooking, you will lose gas if your stove has a damaged gas line. Pay particular attention to any odd odors or faint hissing noises coming from the area near your stove. These signs of a leak may be present.

  • Using a cotton swab, the simplest way to test for a leak is to pull out the stove enough to access the gas line and brush the fittings with soapy water. If one of them begins to bubble, you’ve got a leak on your hands.
  • Leaks should be dealt with immediately, as they can pose a serious safety risk.

Can Gas Bottles Sit in the Sun?


Gas bottles can be left out in the sun without risk. Gas canisters won’t blow up in the light. LPG gas bottles (propane tanks) are made with reflective colors, space for expansion, and pressure release to be used in the sun or the shade. safety devices

LPG gas bottles in the sun contain a 20% ullage area for gas expansion. Therefore, there is an opportunity for expansion. In the unlikely event that the vapor pressure becomes too high, gas bottles also feature pressure relief valves that will let off part of the pressure by releasing a tiny amount of gas.

Gas bottles also employ reflecting colors to lessen solar heat accumulation.BBQ gas bottles weighing 9kg or 20lb exposed to the sun are no more susceptible to heat-related issues than other gas bottles and tanks.

Avoid storing LPG gas bottles at artificially high temperatures. Storage in cars, heaters, machinery or other heat sources is also prohibited.


Depending on the size of the burner and the amount of use, a 13-kilogram cooking gas bottle can last anywhere between 8 and 74 days. The gas bottle lasts eight days when used with a large 15MJ wok-style burner for 90 minutes daily. A modest 5MJ burner used for 30 minutes daily will consume the gas bottle in 74 days.

The amount of gas consumed by appliances is measured in megajoules, or MJ, of energy. The size and quantity of burners have an impact on the total MJ usage. For instance, a traditional-sized gas BBQ might have four or six burners, with each burner typically ranging from 12 to 19 MJ. The most common burners range from 15MJ to 17MJ.
