what size pot for melting snow (for 2) on 12/16/2010 20:44:19 MST Print View

melting snow (&boil in the bag meals/hot drinks) would like to get by w/ a small-ish pot if possible- how small? 1.5 liters, 2.0, 2.5?

1.5 to 2L on 12/16/2010 20:57:27 MST Print View

1.5 to 2 L

Generally enough to fill 1-2 nalgenes in one go

I use the large JetBoil pot (1.3 L??). It's got the "Flux Ring" heat exchanger which makes it a tiny bit faster to boil when used with my MSR windscreen and Backpacker's Pantry fiberglass pot cover oven.

BTW, having a stove that can simmer low enough to bake - like my MSR Dragonfly - makes for great treats like biscuits and cake (yes, CAKE).

BPL 1.1 isnt big enough for 2 people on 12/17/2010 08:25:14 MST Print View

My wife and i have been using a BPL 1.1 pot for this for the last 3 winters.
Its too narrow when on my primus spider, and not big enough when i use the bushbuddy for melting snow.

I plan to buy an 1.5l or 2l pot for melting snow for us 2, and i am searching for the lightest option :)

weights on 12/17/2010 08:50:24 MST Print View

here's what I've looked at thus far,

SP 1400 - 7.4 oz- has a frying pad lid which I don't need, w/o the lid probably ~ 6 oz, but you'd need another lid

MSR Titan 2 liter- evidently discontinued but still available- 8 oz including lifting tongs/lid

MSR Exo 2 pot- 2.4 liter, 9.2 oz- this one fits their polypro deep dish "plates" which might be handy

I stick w/2L pots for melting snow. Sure, I've done it in smaller pots, & they worked fine, but it's more convenient & IME more efficient to use the larger pot. I like to have more hot "seed water" in the pot to retain more heat/melt snow more quickly. The one I've been using is the older MSR you mentioned. The new one would be good, too.

Narrower/taller pots won't be as efficient, or as easy to toss packed snow into.

For budget-minded, Open Country has a plain ol' aluminum 2L pot that's ~7oz (?IIRC) and $15.

What is someting surprising is having a look at pot dimensions / theorical volume according to the maker.

calculating this with water up to 1cm from max height gives :

brand / theorical volume / calculated volume / weight.


BPL1,1l : 1,1l for 86g , 3 oz
MSR 1,3l : 2l for 188g , 6,6oz
evernew 1,3l : 1,2l for 120g , 4.2oz
Snow peak 2l : 2l for 194g, 6.8oz
MSR 2,4l : 3,4l for 262g, 9,2 oz

MSR 1.3L pot dimensions gives 2l volume where is the error ??


so far snowpeak 2l cook and save without the plastic cover seems the best option.

Open Country 7.5oz on 12/17/2010 12:59:36 MST Print View

Jeremy, looks the same, but either their specs are wrong or it's a slightly different model. I have two; they both weigh 7.5 oz, just checked a third & it also weighs 7.5 oz. The bail alone accounts for ~1oz, so theoretically you could get ~6.5oz. Not saying it's the end-all answer, but a decent option on the cheap.

AGG 2 qt on 12/17/2010 13:03:17 MST Print View

Don't forget the $13 anti-gravity gear 2qt pot. Mine is 4 oz without the included lid. Although I have the Anodized (no longer made) version.

Out of stock currently, but may be an easy find on Gear Swap.

what size pot for melting snow (for 2) on 12/17/2010 19:17:57 MST Print View

When Dave and I are melting snow we use a 3L pot to make the process faster. We have found that we need at least 10 L if we melt one time a day. A bigger pot is much more efficient than a small one.

I do use a heat exchanger too.

I use the AGG 2 quart pot for 2-person snow camping - works great for me.

Raymond- tell more a little about the heat exchanger- I see MSR (maybe others?) has one that fits a 2 liter pot- it's 6 oz- is that a worthwhile/justified 6 oz? they also said it can be slid down a bit to be used as a windscreen w/ a Windpro (stove I will be using)

thanks

I have a couple of Primus pots with the built-in heat exchanger, and they seem to work great. You can hold your hands against the sides of the pot and not feel any heat coming up. Downside is they're heavy.

For any short trip of like a week or less, they don't save enough weight of fuel to make up for their weight

See the comparison of stoves from several months ago - includes non heat exchanger stoves and heat exchanger stoves

heat exchanger on 12/18/2010 14:06:40 MST Print View

Joe- yeah 6 oz is almost the weight of a pot- it would have to work really well (which maybe it does???) to make it worthwhile, ie enough added efficiency you need less fuel (which winter camping and melting snow takes a fair amount)

if it actually doubled as a windscreen that would be another justification- it seems if you lower it (for a windscreen) then your losing the ability to put heat into the sides of the pots

climbing bums on 12/18/2010 14:14:13 MST Print View

note that a lot of climbers will use heat exchangers for routes where melting snow is needed

steve house used it on his first ascent of the rupal face on nanga parbat ... this is on the route where they needed to climb alpine style and carry everything up with him ... he's the guy that takes parts out of his crampons to save weight

you can see his equipment here ...

jerry- thanks- that's kind of what I figured

eric- that's a neat heat exchanger- looks like a guy could fashion one out of ti foil (maybe) and probably get it in the 2 oz-ish range- hmmmmm....

eric- thanks, shot him an email- also bumped an old thread that had some discussion on a diy ti heat exchanger, but no one actually posted one they had made
