The 45kg cylinder is sometimes called the Exchange-only bottle in certain countries. Many brands in the UK, Australia, and elsewhere provide the Swap'n'Go option.

When your 45kg cylinder runs out, you can swap it for a full one. Your local gas supplier will deliver a replacement cylinder and handle the exchange for you, so you'll always have gas without interruption. You can easily order refills online or by phone.

How To Calculate Your Gas Usage At Home

To know how long a 45 kg gas bottle lasts depends on various factors such as the family size and usage habits. This will help you estimate usage more accurately.

The size of your family directly impacts how quickly you use gas. Larger families tend to use more gas for cooking, heating water, and other household needs compared to smaller families or individuals. A large family of 4 or more people, typically will use gas more frequently, especially if they cook multiple meals a day, use gas for heating water, and possibly for room heating during colder months.
And for small family of 2-3 people, they may use gas less frequently, as it still remains a clean energy source for cooking.

To estimate gas consumption, consider these average consumption rates:

* On average, cooking with gas consumes about 1-2 kg per week for a family of four. This can vary based on the number of meals cooked and cooking methods.
* Gas water heaters can use around 1-2 kg per week depending on usage frequency and the power voltage of the heater.
If gas is used for additional purposes such as heating rooms or running a gas dryer, consumption will be higher accordingly.

Let's calculate how long a 45 kg gas bottle might last based on typical scenarios:

Family Size: 4 people

- Average Cooking Consumption: 1.5 kg per week

45 kg X 1.5 kg/week = 30

So, a 45 kg gas bottle would last approximately 16 weeks for cooking needs alone.

- Including Water Heating:
Average Water Heating Consumption: 1 kg per week.

Including water heating, the bottle would last around 12 weeks.

Your actual usage may vary. To refine your estimate, track gas usage over a month to gauge your specific needs accurately. Factors like seasonal variations in usage (more gas used in winter for heating) should also be considered.

You need to estimating how long a 45 kg gas bottle will last involves understanding your family size and usage patterns. You can determine roughly how many weeks your gas bottle will provide energy by doing this.
