I was reading the Calor Gas FAQ at: http://www.calorgas.co.uk/faq/which-gas.htm
It makes the interesting point that butane boils at 0 degrees Celsius, so butane cylinders won't work in the cold.
It also says that propane should be used for barbeques and patio heaters. Is this for the same reason or is propane cheaper to produce? Surely no-one would want to be under a patio heater or be barbequing when it is freezing? Why can't butane be used?
I thought I read somewhere on the same site that only butane can be used and stored indoors and that propane can only be used indoors on a temporary basis, e.g. a plumber's blow torch. Is there a safety reason for this? Is propane inherently more dangerous? Why?
I presume that is why indoor heaters have to use butane? That can't be helpful if the temperature drops to freezing! I guess you have to turn the heater on before it gets that cold. That said, are such heaters recommended? I thought that for domestic use they cause condensation issues and didn't someone die from poisoning (carbon monoxide)? Probably best to use a fan heater if possible?
Thanks in advance.
