Even propane which boils at -42 degrees C can be problematic if the rate of use is high. A few years ago we ran a Winter Ball in a m****** big tent. We heated the tent with industrial space heaters. After an hour or two the big propane bottles were thick with ice and the heaters producing very little heat. Presumably the evaporation had chilled the gas to the boiling point.
That said I have never had a problem with propane when caravanning in winter, using it to power a little gas heater.
Pure butane boils at -1 degree C. We used to used it for making hot mulled wine at our annual village Christmas event. We used to keep the bottle in a warm place beforehand and then insulate it, which kept it going long enough provided it was fullish.
Patio gas appears to be a blend of propane and butane. We have been using it for several years for barbecues at events, including bonfire night. However it is now stupidly expensive and costs significantly more than propane, which I assume is just the branding. 13Kg is now £68 for a refill locally. I no longer maintain the equipment but I am going to suggest we get some propane regulators (similar pressure but with a generic connector) and go on to propane.
