There’s a broad range of Flogas gas bottle sizes in different types of gas, primarily Propane, Butane, and their “Gaslight” leisure range. The suitability of each depends on the application and whether it’s for indoor or outdoor use.

Here’s a breakdown of common Flogas bottle sizes and their suitable applications:

1. Propane Gas Bottles (Red Cylinders): Propane is ideal for year-round outdoor use, as it has a lower boiling point and performs well in colder temperatures. It’s also suitable for some indoor applications where bottles are housed outside.

- 3.9kg Propane:
  - - Suitable for: Smaller heating appliances, camping, some small commercial applications (e.g., blowtorches).

- 6kg Propane (including “Leisure” 6kg):
  - - Suitable for: Small to medium BBQs (3 burners or fewer), smaller mobile commercial applications, caravans, workshop tools, leisure appliances, small pizza ovens.

- 11kg Propane (including “Leisure” 11kg)
  - - Suitable for: Larger BBQs (3 burners or more), patio heaters, outdoor catering, events, leisure activities, mobile catering, larger commercial setups.

- 19kg Propane:
  - - Suitable for: Larger domestic heating and cooking, commercial applications.

- 47kg Propane:
  - - Suitable for: Larger domestic heating and cooking, businesses, and situations where there isn’t space for a bulk LPG tank. This is the largest cylinder size for general use.

2. Butane Gas Bottles (Blue Cylinders): Butane is generally recommended for indoor use or outdoor use in warmer months, as its boiling point is higher than propane.

- 4.5kg Butane:
  - - Suitable for: Smaller indoor portable heaters, camping stoves, smaller indoor cooking appliances.

- 7kg Butane:
  - - Suitable for: Indoor portable heaters, indoor gas appliances (e.g., cabinet heaters), caravans, outdoor cooking in warmer weather.

- 13kg Butane:
  - - Suitable for: Larger indoor portable heaters, indoor cooking, and general indoor gas applications. This is the largest butane cylinder in the Flogas range.

3. Gaslight Bottles (Translucent Cylinders): These are Flogas’s lightweight, translucent cylinders, allowing you to easily see the gas level. They are designed for leisure use.

- 5kg Gaslight:
  - - Suitable for: Patio heaters, smaller BBQs.

- 10kg Gaslight:
  - - Suitable for: Patio heaters, BBQs, and general outdoor leisure activities.

Important Considerations:

- Regulator Type: Always ensure you use the correct regulator for your gas bottle. Flogas Propane and Butane bottles require different regulators (e.g., 27mm clip-on for some leisure propane, 21mm clip-on for butane, or screw-type for standard propane). Check your appliance instructions.

- Indoor vs. Outdoor: Propane is generally preferred for outdoor use, especially in colder weather, due to its lower boiling point. Butane is more suited for indoor appliances.

- New Cylinder vs. Refill: When purchasing a new cylinder, there is usually an initial service charge or deposit. For refills, you typically exchange your empty bottle for a full one and only pay for the gas.

- Commercial vs. Domestic: Some sizes are more geared towards commercial use (e.g., forklift gas), while others are for domestic or leisure applications.
