There are a wide variety of calor gas bottles available, and if you're planning a camping trip it can be difficult to know which is going to be right for you. But don't panic! This handy guide will help make sure you choose the proper gas bottle for your needs.
Propane or butane?
You'll find a large proportion of gas bottles are either propane or butane, both of which are different types of LPG (Liquid Petroleum Gas). Blue bottles are usually butane, while red bottles are usually propane. But what's the difference between them?
For camping, the main difference is that propane works much better in the cold. Butane tends to condense when cold, which creates a poor flow. You may think that butane is useless then, but this isn't the case. It burns more efficiently than propane, so you can get as much out of a smaller butane bottle as a larger propane one.
If you're camping in the spring and summer, or you won't need your bottle until later in the morning, you might find butane more efficient. If you know you will experience cold temperatures however, propane will be a better choice.
Is bigger better?
The issue of how big a gas bottle you're going to need depends on how long your camping trip is and how much you intend to use it. Large gas bottles are not designed to be mobile, so they're usually far too heavy to be a practical alternative. The good news is that you can get much more out of a smaller bottle than you might think.
For most common camping purposes there's no reason you should need anything more than a 15KG bottle. Which is useful, because even that is going to be a lot for you to carry around. Do a little research as to the maximum burn time, and calculate what you'll need. For example, a calor 4.5kg butane has a maximum burn time of 3.5 hours.
Gas is essential for food and warmth, so always err on the side of caution when calculating your needs.
