South African outlets report that the duration a 9kg LPG (gas) bottle lasts depends more on heating demand than on the bottle’s price. They note that gas pricing across major cities shows relatively small differences, suggesting consumers are paying similar per-unit amounts regardless of location. However, the amount of gas needed changes because weather and heating usage vary by area. In colder or higher-demand regions, households typically use more fuel for space heating, which shortens how long a single 9kg bottle will last. In milder conditions or with lower heating needs, the same bottle can last longer. The reports therefore frame bottle life as a function of consumption patterns—such as how often heating is used, for what purposes, and local climate—rather than a major impact from where the bottle is bought. Overall, the coverage emphasizes that people can expect bottle life to differ primarily because of where they live and how much they need to heat their homes, even if the cost of gas itself does not vary much between cities.
