Complete Guide to Gas Bottles for Caravans
Gas bottles are essential for heating, cooking, and powering appliances in caravans. Understanding the various aspects of using gas bottles ensures safety, efficiency, and convenience during your travels. This guide from Shropshire Gas covers everything you need to know about gas bottles for caravans, including types, sizes, durations, and specific uses.
Types of Gas for Caravans
Propane:
- Suitability: Propane is suitable for all-year-round use, including colder weather.
- Performance: It vaporises effectively at lower temperatures, making it ideal for winter trips or high-altitude locations.
- Availability: Commonly available and easy to refill at most gas suppliers.
- Identification: Red or orange bottles.
Butane:
- Suitability: Butane is generally used in milder weather conditions as it struggles to vaporise in cold temperatures.
- Performance: Best for summer use or warmer climates. It provides a high energy output and is efficient for cooking and heating in appropriate conditions.
- Availability: Widely available, but less commonly used for caravans in colder regions.
- Identification: Blue bottles.
Gas Bottle Colour Codes
In the UK, gas bottles are colour-coded for easy identification, ensuring you select the correct type for your needs:
- Propane: Red or orange bottles. These are suitable for year-round use, including cold weather, making them versatile for all seasons.
- Butane: Blue bottles. These are better for use in warmer conditions and may not perform well in cold temperatures.

Choosing the Right Gas Bottle
Selecting the appropriate gas bottle for your caravan depends on your usage patterns and the type of caravan you have.
For Touring Caravans:
- 6kg Propane Bottle: This compact size is perfect for short trips. It’s easy to transport and store, making it convenient for frequent travellers.
- 7kg Butane Bottle: Ideal for those who travel in warmer weather. This size offers a good balance between capacity and portability.
For Static Caravans:
- 19kg Propane Bottle: Suitable for extended stays or permanent setups. This size provides a substantial supply of gas, reducing the frequency of replacements.
- 47kg Propane Bottle: Best for static caravans with high gas demands. This large size ensures a steady supply for heating and cooking over longer periods.
Gas Bottle Sizes and Durations
The duration of a gas bottle in a caravan depends on its size, the number of appliances, and usage patterns. Here are some general estimates:
6kg Bottle:
- Duration: Typically lasts around 1 to 2 weeks with moderate use, including cooking and occasional heating.
- Usage: Ideal for short trips or infrequent use.
13kg Bottle:

Specific Uses and Durations
Understanding how long a gas bottle will last based on specific uses can help you plan better and avoid running out of gas unexpectedly.
Heating and Cooking:
- 47kg Bottle: Lasts approximately 4 to 6 weeks with moderate use. This size is ideal for static caravans where heating and cooking are regular activities.
Heating Only:
- 47kg Bottle: Lasts around 3 to 4 weeks during colder months with regular use. This is a critical consideration for those who use their caravan in winter.

- 9kg Bottle: Can last around 2 to 3 weeks of continuous use, depending on the fridge’s efficiency and ambient temperature. A dedicated bottle for the fridge ensures you don’t deplete your main supply.
Choosing the right gas bottle and understanding how long it will last is essential for a smooth and enjoyable caravan experience. Whether you’re planning short trips or long stays, knowing the size, type, and duration of your gas bottles helps you prepare adequately and avoid any interruptions in your gas supply.
