Gas for Caravans
| There are two basic types of gas available, 
		Propane and Butane. If you caravan in the winter or colder weather you 
		will need Propane as it works to a low temperature where as Butane 
		starts to 'give up' below 6C. Cylinders are normally described by the 
		weight of gas they contain when full. Butane cylinders hold more gas for 
		the same size, ie external dimension. There are different materials for the containers. The 'old' steel containers are the heaviest for example, Calor Propane and Butane. Calor have now introduced a light weight steel container called 'Calor Lite' BP now MacGas use a lightweight bottle and a translucent design – making the gas level visible. |

This type of regulator is fitted as

I use 10kg and 5kg BP now MacGas lightweight bottles of Propane gas
The Bailey Senator has an automatic changeover valve and Truma regulator. The inlets have a right angle adaptor so that the connecting hoses fall away from the regulator supposedly to stop contaminating substances from entering the regulator and blocking it, a well known problem.
My latest van a Bailey Unicorn uses a Clesse regulator
which is reported as being much less susceptible to blocking
It is seen here with a 10Kg MacGas gas bottle and a stainless 
steel pigtail,
this set up should avoid the 'oil blocking' problems

French Antargaz

Butane 10 kg
I visit the continent most years so have bought a French gas bottle and refill it every year as it is very cheap compared to gas prices here and is see-through so you can see how much is left.
