In reply to Removed User: Hi everyone
I have been using mainly Trangia’s in winter with Meths, or a Gas adapter with a Winter Gas Mix if the conditions are milder. I find usually the Gas doesn’t perform to well when conditions are very cold. For example, on Pen-y-Fan summit last week, it was –12 C and I had my Jet boil, it took 15 mins just to get it to heat the water to around 40 degrees. I kept the canister off of the cold ground, and even held it between my thighs to keep it from going to cold. The gas looses pressure when it gets to cold so the stove under-performs.
I had a small Trangia with me in case this problem arose, and I got it to boil the water using Meths within around 13 mins. I used the snow that was obviously in great abundance, I started by getting snow to melt into the kettle to a depth of around 1cm, I kept the kettle not on the Trangia but held it above so the snow would not scorch and evaporate, I could have used the simmer ring, but it did’nt matter, I just wanted to melt the snow in the kettle.
Once the snow had melted and heated to around 70 Degrees C, I added the extra snow, in small pieces so as not to loose to much heat in the kettle, once the water was about 1 inch deep I added bigger pieces, the whole process took around 13 mins, and I had a litre of hot water (of which I did’nt need to strain as it was clean from particles), and just kept adding snow as I kept making tea. The Meths will run out quicker, because the flame will take longer to boil the water from frozen. Meths is much more reliable, even though it is stubborn to light went cold.
I think these high fangled stoves are well made and can do well in summer, they may look cool and impressive, but they just give you headache when they don’t perform, A typical cheep Go Systems buner for £15 will do the same job as a MSR Firefly as long as the burners are sheilded from the wind, I know as I have both of them. I have had about 7 stoves; mainly MSR and I use them for summer and mild seasons, the MSR Windpro is a good stove, with the foil shield, however remember it’s not the stove that fails it’s the gas and the canister. If you were to provide heat towards the canister then it would perform better, I dunked my canister in warm water once and found that it performed much better, until the water went cold. I’m not overly keen on playing about with gas for the obvious reasons.
I’ve had much experience with cooking in winter, and gas can work in the right conditions, but once the canister gets super cold, as it will when being used, the gas inside will turn towards a more liquid state and loose it’s gaseous state meaning less pressure. I would take twice as much Meths in winter as you would in summer, the Meths will run out quicker as it’s harder for the flame to get ‘cold’ water to boil. If you get the gas adapter with the Trangia which really powerful, then you have an all in one solution for cooking with a very reliable backup if the gas fails to work for you.
Merry Christmas all
