Propane boils at -47C whilst butane boils at 0C so essentially once the ambient temperature approaches OC, then butane cannot boil off inside the cylinder to produce a vapour.
Realistically, butane is most efficient between 13C - 20C so if your boiler is externally mounted alongside the cylinder then butane will struggle to produce enough vapour pressure for the boiler to burn. It also doesn't help that Spanish cylinders are so small which further reduces the offtake regardless of the regulator which inhibits its usefulness on appliances with larger KW offtake requirements.
I'm assuming that's what you meant by 'gases being hotter'?
