I need to get a smaller butane cylinder to take away with us as the 15kg one just takes up too much room ! Not sure if I should go for the 7kg or if I could get away with the 4.5kg though.
Will one of the small 4.5kg run a double burner and if so how long would you say it would last if we used it to cook brekkie, dinner and a boil a few kettles each day ?
No problem running a double burner, and since the gas will be at the same pressure, it should last almost a third as long as your 15kg one does, with similar usage.
The smaller the cylinder you buy the less value you get so working on that philosophy you would be better opting for the 7kgs. if possible in terms of value for money anyway.
I'd guess that with "normal" use it should last quite a bit longer than six days. If you're worried about exactly how much is left in a part-used Calor cylinder, weigh it and subtract the tare weight (marked on the aluminium "collar" - it's in pounds and ounces though!) to give the weight of the remaining gas.
Worth pointing out that 4.5 kg Calor butane uses screw on regulator so you will need a new one if you change from 15kg bottle. The 7kg bottle uses same 21mm clip as 15kg.
I think I'm going to go for the 7kg (I can get an empty one to swap) It's not that much bigger than the 4.5kg and saves having to get another regulator.

Officially they are not supposed to, but our local supplier did, I think probably as he was not a caravan specialist, more a garden and builder's merchant place, so not so much demand for the 7kg.
------------- Yes, the car is bigger than the 'van.
I work for a national builders merchant and will swap any size bottle for any size refilled because as a national account holder for the gas company we only have to return a bottle to them and it is not size related.
