alcohol stoves at elevation and in winter

[Blakej]

I was wondering if anyone has a good site for the effectiveness of alcohol stove as elevation increases. That or any experience using them at elevation. I've used mine under 7000 fairly effectively to melt snow but I would certainly hesitate to test its ability to work well much higher and in colder temps. Oppinions?

I haven’t use alcohol stove at high elevation but i have lot of experience using it in cold temperatures. Alcohol stove is most common stove around here and temperatures around –20F are usual. Once I used alcohol stove in two week trip and it was –50F for the first week. Stove (trangia) works just fine as long as you remember to put heating candle under the burner. Otherwise it is useless.

Here's the reason why I'd never choose alcohol over white gas: The heat of combustion per gram of white gas is about 1.6 times that of ethyl alcohol, and almost twice that of methyl alcohol. You need way more alcohol to do the same job.

yes but if your only planning on melting water for a one or maybe two day climb your still saving weight cooking not included. I just wonder at what elevation the alcohol stove begins to be significantly effected.
