I,m in abit of a dilema in my caravan i use butane blue bottle gas but i was talking to a bloke the other day that uses propane can anybody explain the differences between them, i know propane freezes at a lower temperature but have also been told it burns hotter is there any truth in this and which one am i better off using propane or butane or do i use butane in the summer and propane in the winter.
i was always told to get both....no idea why other than the cold....now you have me thinking that propane is the way to go.
i do know that propane has a lower boiling point than butane, but what that means I have no idea!
i am about to get two botles for our new van (picked up 2x 15gk at the local tip and was going to trade-in and get 2x 7kgs) and was planning on getting one of each, mainly due to use in the winter.
i recall using propane (red) many years ago on some commercial burners mainly as they seemed to think they were hotter.
"On a per-volume basis, butane is a more efficient fuel than propane, by around 12%. This means that a similar amount of butane and propane will yield more energy for the butane".
also i have realised that propane is a 6kg and butane 7kg.
butane may be better value....hence have both so you can still use the propane in the cold

Butane actually burns slightly hotter than propane so, in theory, there's a slight benefit from using butane in the summer and propane in the winter.
But the difference is very small and there can be chilly mornings in the middle of a British summer that may mean you have to wait ages for your morning cup of tea or coffee.
AND you have to have two regulators or hoses to be able to switch.
I use propane just for the fact you only need one regulator across the different cylinder sizes.
It also smells more pungent than butane, so in my opinion, is safer, as you're more likely to detect a leak sooner.
The real world difference between the two in terms of time to boil a litre of water isn't really worth considering...
