just been given a bottle of gas but it's propane and not butane is this safe to connect to the cooker to cook with or does it really need to be butane gas ?
many thanks
steve
oh right cool thanks :)
i knew propane burns hotter than butane just wasnt sure if it was ok for cooking with i've used it with a burners torch but thats it ...lol
It looks like many a supplier is jumping on the camping bandwagon. Perrhaps because of the bad weather gas has been higher demanded. On the other hand less people would be camping.......i'm sticking with my 4.5 that i share with the barby at home....£12 quid in stoke.

thanks all :) steve
It's not better for use in cold conditions because it burns hotter (not sure it does - I thought butane was actually fractionally more heat efficient than propane? someone more technical on here will know for certain on that point). No. The reason propane is better in cold conditions is because it vaporises (ie is useable) at lower temperatures. Typically, butane ceases to vaporise (so won't light!) as you get down to within a few degrees above freezing (5 dgrees or so seems to ring a bell?). In real terms that means it can give trouble on colder evenings/mornings early or late season in this country, even if it isn't actually frosty. Propane continues to vaporise colder than that so can still be used early/late season & in winter (not sure how low it has to get before it too fails to vaporise).
thanks for that info TrickyWoo :)
as long as it's safe to use for camp cooking that'll do me fine .didn't really want to change a full bottle of propane for an empty bottle of butane they said thats what they would do that would mean they wouldn't refund any gas i had left if i was to swap it for butane :(
i'll use this bottle first then swap to butane i think
The reason that propane is better in cold weather than butane is down to the boiling point of the gas, this is the point where the gas turns from a liquid into a gas and the minimum temperature that butane will boil is around zero degrees centigrade, so if you want to go camping in sub zero temperatures then you had better take your red propane cylinder as your blue butane will not work
