All good info, what liquid/gas stoves are the best ---- I have a coleman old school white gas stove (the kind you pump up , but the fuel is kept in the stove baee and i worry about fuel leakage if put in a pack) and it works well at normal temps but is heavy compared to the ultralight stoves--- I guess I've never realized that white gas stoves were better in the cold
I see msr has "dual fuel" stoves that can use iso/but or white gas/kerosene/unleaded fuel
I guess the real thing comes down to total packable weight, size, and how low of temps you expect to encounter--- also weather you are boiling water for freeze dried food or if you plan to cook any traditional food too---- and length of your trip and availability of water.
If you aren't packing all your water then your boil times per meal for freeze dried food would be increased due to having to purify your water--- In the areas i hunt, there is water available but often times its in a pond and would definitely need increased boil times--- you could use the water filter systems but I'm still not 100% trusting they get all micro nasties out and still boil/purify my water
I suppose on longer adventures, something like the biolite would eventually over come the weight penalty of having to carry a bunch of iso canisters since you just use sticks for fuel on the biolite stove and can easily increase cook times for traditional food with more sticks.
Sounds like you get about 18 liters boiled ( not purified/sterilized) per 8 oz canister -- and maybe 10 liters purified per canister
If you were boiling/purifying 1 gal per day for food/drinking ypu would get 2 to 2.5 days per 8 oz canister -- so if you had a 10 day hunt you would need 2.5 pounds of iso fuel plus the stove and pot so about 3.5 pounds for the combo-- where as the biolight stove and pot weigh about 3 pounds - you use sticks but also have the ability to charge your phone off the battery pack, I wonder how the biolight battery pack performs in cold weather ?
All good stuff to consider
