Liquefied petroleum gas

Gas services are vital sources of heating and cooking for caravans and motorhomes – especially in when touring in the winter months. Here are the fundamental considerations all caravanners and motorhomers should be aware of.

What sort of gas should you use?

The most commonly used varieties of LPG for leisure use are propane (C3H8) and butane (C4H10). These are gases at normal temperatures and pressures, but can be liquefied by the application of a relatively low pressure. Because a small volume of liquid equals a very large volume of gas (l to 274 for propane, l to 233 for butane) a small pressurised cylinder can contain a significant amount of 'energy' for your caravan appliances.


Butane will only readily change to a gas above 0˚C, so is generally suitable for the spring to autumn caravanner.  Propane, on the other hand, will become a gas down to -40˚C and, therefore, can be used in winter, or all year round if desired.  

Information - Cylinder exchanges

Most suppliers operate a hire agreement on cylinders, which remain their property. Keep the original hire agreement safe, because if you want to return the cylinders at any time, you will get a proportion of the hire fee back.  The hire form may also be required if you wish to switch cylinder sizes, or from butane to propane.
