Not sure what the difference is between flogas and calor gas, would value clarification. Thanks very much.
Hi Holidaysforever,
Calor Gas and Flogas are just distributors of LPG gasses. There are many different companies selling these gasses, and its very much like high street filling stations that are branded like Shell and Tesco ( to name but two) the name is not really important as they are all basically selling the same stuff.
Unlike Petrol and Diesel, where you will do some very expensive damage if you use the wrong one, Caravans are quite lucky because almost without exception you can swap between Butane and Propane LPG without any problems - except the one major difference between Butane and Propane is the ambient temperature which affects the way the gasses work.
Butane gas will not vaporise properly below a bottle temperature of about 4C. This means butane is really only a two or possibly three season gas. Propane on the other hand continues to vapourise with bottle temperatures down to about -40C. This makes it great for winter caravanning.
There are some other small difference in the gas but most of them are too small for the normal user to notice.
Bothe Butane and Propane bottles have different bottle connectors, so you can't accidentally change over.This stems form the days when you needed a 37mb regulator for Propane but only a 28mBar regulator for Butane.In modern caravans both gasses now use the same regulator pressure of 30mBar. which is now the European standard. Again in the UK Commercial propane always uses the same bottle connector, abut there are some specialist uses such as patio heaters which use a different bottle connector.
There are greater variations in Butane bottle connectors, but the sizes most commonly used by caravanners tend to have the same type of connectors.
If you look at continental gas suppliers probably the best know is Camping Gaz, and they use totally different bottle connectors.
BUtane is almost exclusively a gas used in leaiures pursuits and only a handful of companies actually sell it., where as Propane is used extensively in commercial and business.
