British equivalent to an shit is the Hexy stove , pick em for about 4 quid , hexamine fuel tablets refill pack about 2 quid , they work all be it much slower than gas hence they aren't used much now with things like the Jetboil out there , brewing up in 2 min's instead of 10 , still a place for it in my kit though.
Nothing is fool proof for a sufficiently talented fool!!!!
