How Long Does a Gas Bottle Last?

How long a gas bottle lasts depends on the size of the cylinder, the appliance you are using and how often you use it.

A larger cylinder contains more gas and will generally last longer, while an appliance that uses more gas will empty a cylinder more quickly.

🔥 Typical Uses

Home Heating

Gas used for heating can vary considerably depending on the size of your appliance, how long it runs and how well your home is insulated.

BBQs & Patio Heaters

A cylinder used for a BBQ or patio heater may last for several weeks or months with occasional use, but frequent or prolonged use will use gas much faster.

Camping & Cooking

Portable cooking appliances generally use relatively small amounts of gas, so a cylinder can last for quite a while when used for short periods.

What affects how long it lasts?

Cylinder size
Larger cylinders contain more gas.

Appliance size
An appliance with a higher gas consumption will use a cylinder faster.

How often you use it
An appliance used for an hour a day will obviously use less gas than one running continuously.

Weather conditions
Heating and outdoor appliances are often used more during colder weather.

Want to estimate your usage?

If your appliance shows its gas consumption in kg/hour, you can make a rough calculation:

Cylinder size ÷ appliance consumption = approximate running time

For example, an appliance using 0.5 kg of gas per hour connected to a 11kg cylinder would theoretically use the cylinder in around 22 hours of continuous operation.

Actual usage can vary, so treat this as an estimate rather than a guarantee.
