Hi Hacksaw,

Propane bottles aren't especially that great as a stove fuel because the cannisters are quite heavy and have much higher working pressures.

There are a number of ways in using conventional Butane/propane canisters such as the ones shown below to work in below freezing conditions.



The following link gives an excellent description of how to operate gas stoves at low temperatures. The trick is to invert the canister and let the liquid butane fill the hose to the gas stove either by gravity feed or pushed out by the pressure provided by the propane. This sort of stove can be run down to below -20 C (the limit is about -26 C). The only proviso is the stove has to have a preheat tube.

Example - Home made Aluminium stand to invert the standard 70/30 butnae/propane cannister.

This solution works well with a Primus Himalaya Omnifuel liquid fuel stove. (it will also burn white gas/petrol/diesel/paraffin/Jet fuel/Vodka etc)
