Gas for Caravans and Motorhomes
There are two basic types of gas available,
Propane and Butane (both are called LPG, Liquefied Petroleum Gas). 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. Both types are suitable for Bailey
Caravans and Motorhomes and use the same Bulkhead regulator. The gas is held in liquid form in the bottles
which is why you may hear the liquid ‘sloshing’ around when moving the
bottles. To use the gas the bottle needs to be fed through the Regulator
which will reduce the pressure of the gas to 30mbar for use by the
appliances which all run at that pressure. There are different materials for the containers.
The steel containers are the heaviest for example, Calor Propane and
Butane BP introduced a lightweight bottle and a
translucent design – making the gas level visible. This is now supplied
by Flo-Gas. More and more members have switched to using a
refillable cylinder, ‘Safefill’
being one of the main brands. |
Safefill are a supplier
of refillable lightweight gas cylinders that can be filled by the owner
from an LPG supplier. The Supermarket Morrisons are one of the biggest
suppliers of LPG that allow customers to fill these cylinders, but many
other LPG suppliers will also allow this. The cylinders are designed
with an automatic shut-off valve to allow safe filling by the users.
They are available in 5Kg 7.5Kg and 10Kg sizes. The gas in the LPG
outlets is Propane so suitable for use in the winter. One of the
advantages of these cylinders is they can be easily topped up so you
don’t need to wait till empty before recharging them.
Although the cost of buying a new Safefill cylinder is quite
expensive (£200 - £230 this can be offset by the price of gas. At the moment
(February 2023) Calor Propane is between £4.50 and £5 per Kg. Morrisons
LPG is 79p per Litre or
£1.50/Kg a significant saving. So if you use a lot of Gas a
refillable bottle is a good investment. |
Gaslow also offer refillable metal cylinders and some Motorhomes have had a gas tank fitted to them that can be filled up from an external filler point. This calls for a specialist installation. |
One of the questions we are often asked is ‘how much gas will I use?’ Well that’s impossible to give a generalisation as it is totally dependent on what you are running on gas. If you are on Electric Hook Up (EHU) most of your outfit will be running on electric. If you are Off-Grid, for example on a Rally Site with no power, The consumption will be time of year/weather dependent. In the summer months, you will be using the fridge and cooking on gas. In the winter/colder months you will also be using the heating. This consumes a lot more gas and you can easily use up a 6Kg bottle over a weekend. So important to carry a reserve supply i.e. two bottles and be aware how full they are. |

Truma 30mbar Bulkhead Regulator
CLESSE 30mbar Bulkhead Regulator
These type of regulators are fitted as standard to many modern British Manufactured caravans and Motorhomes. You will need an adaptor hose to go between the bottle and this regulator, this is called a pigtail. |

Stainless Steel Pigtails
Although the Stainless Steel ones cost
more they last longer than the ‘rubber’ ones. The ‘rubber’ ones should
be changed every 5 years, a date of manufacture should be printed on the
pigtail. Stainless Steel ones have a life of up to 20 years. |

There are two types that can be found on Bailey Units. These must be
