If you’ve ever wondered if you really need to bring more than one fuel canister, this video is for you. In it, Katie covers how to plan how much water you’ll need to boil on your trip, how to test your stove to see how many boils you can get out of a full canister, and how to use all that info to figure how much fuel you’ll need pack.
If you’ve got a bunch of half-empty canisters laying around, check out our video to see how much fuel is left in them: • How to Measure Caniste...

Passing on some advice I got a long while ago: write the total weight in grams w/ sharpie at the bottom. Then at the end of each trip, do it again.

@toml.8210 3 года назад

That's not a bad idea. It's about the same as she did in the video. After the trip, you can figure how much fuel (on average) for each boil by figuring the difference and dividing by the number of boils.

@andrew40 8 месяцев назад

I don't think that's true, though. The bulk of the fuel in the canister is liquid and the partial pressure doesn't change depending on how much is used. Assuming consistent temperature, the gas pressure is the same until very near the end when all liquid vaporized.

If you are using filtered water from a stream it is going to be COLD which will affect boil time. Great Video, thanks.

@seaotter52 5 лет назад

There's no need to go to a full boil for most rehydration cooking. If you stop when you start getting a couple of bubbles on the bottom it will be plenty hot especially when you use a coozy. Depending on the food, I have the stove on less time, maybe 25-30% less. For hot chocolate I only heat till hot to the touch.

Sure it's under ideal conditions, but the test gives a nice baseline. Thanks for the video. I prefer to carry esbit so I can take just the right amount of fuel and not have to carry around empty canisters, but this is a great starting point for thinking about how many canisters to carry for when I have to take the old MSR.

@kirkw1740 3 года назад

So 27 min 30 sec to burn through 100 g of fuel with that setup. I'd be really interested to see a comparison of burn times and boil times for different burners and tanks. I'm also curious what position your valve was in, but assume it was fully open.

@FIA55902 4 года назад

Huge difference between boiling cold water in winter and boiling warmer water in summer. Obviously wind and altitude also play a role. It's probably more reliable to keep track of how long you've used a particular container, since assuming that the stove is burning full on, the time per canister should be relatively reproducible. Once you know that you get X number of minutes of burner time from a canister, you can just time each boil on the stopwatch on your phone, and keep a phone note of time used for the canister.

@TDSudduth 5 лет назад

Nicely presented; excellent information! My results show about 3 minutes per boil for 500 mL (at 8,200 feet elevation). Complications as noted here and in comments are starting temp of water and wind, and not noted but critical, elevation. So bottom line, for minimalist, ultralight, 5-7 day section at 10,000 to 11,000 elevation with ONE canister I will start with one 3-minute boil per day (dinner), use wind screen, warm icy creek water in pack or even perhaps with body heat, then splurge on two boils per day in final two or three days. Comments?

@bradleyjohnson322 3 года назад

I like hot breakfast and suppers. So i plan on two boils a day... i carry a altoids mini emergency stove in my pack for lunch or a mid afternoon drink. Start to finish about 9 min with set up boil cool down and crushing out the ashes. I also use aluminium foil for windstop and couple loose rocks as back stop. And 250 ml of water to drench the ashes.

This is a decent baseline so long as you make sure to control for the temperature of the tap water; however, you'll want a much more conservative 'safety' margin than 1.25, preferably > 1.5 or even 2.0 if hiking in cold, windy conditions.

@JohnFisk-OHS-78 3 года назад

As so many have said: Excellent video! Probably the best take home message - do your own homework if you tend to be OCD and want to be prepared. The alternative is to risk over- or under-resourcing. Admittedly, you can probably live without a stove for an entire through hike, but.. ***shudder*** who would want to. Hot caffeine in the AM fuels human existence. Experiment in your backyard and have some fun. Again, many thanks!

I did a camping trip last week and barely had any fuel in one canister, it lasted me the entire trip, two breakfasts (including water for coffee and oatmeal, plus bacon for the first morning) and two dinners (boiling water and cooking meat). I was very impressed with my stove I used and how little fuel it took to feed me for the three days I was gone. I even had major windy conditions both evenings. I had a snow peak canister. I still took an extra canister with me, in case I ran out of fuel (No fires and no BBQs where I was camping, stoves must have regulators on them).

@sagehiker 5 лет назад

I agree, in most real world conditions, 10 boils of 500 ml of water per standard iso butane canister with an MSR Pocket Rocket us about right. And it also validates my inclination toward liquid fuel stoves for more than three days and if you like more than one hot meal a day. Light up the stove wars.....

@GregoryVeizades 5 лет назад

After getting a free MSR Dragonfly, I think i've found my perfect stove for me. I'm usually cooking for more than just myself, and it just made carrying one medium size fuel bottle for 3 days vs the 3 ISO canisters I used to to have to carry with my Whisperlite Universal. (Yes I know the Whisperlite can use liquid fuel) But the dragonfly is the better stove in my opinion.

@sk8erdawg25 5 лет назад

For all the people saying they use wood to boil water and don't use stoves, keep in mind that in some places it is illegal to have open fires. Also, during certain times of the year or after an extended period of time without rain it is also illegal. Thru-hikers use them for the first reason. Some places, like Harper's Ferry WV, you can't have open fires or stoves. That is because of a historical fire that occurred there I believe.

@mhitchner 5 лет назад

I get a kick out of the people commenting and talking about how its a waste to bring fuel. Many places you go there is no fuel. What do you burn above tree line or in the desert? Lichen? Rocks? Sand? I also got a kick out of people saying fuel is a waste of weight yet they say they bring guns/ammo/axes/etc... talk about a waste of weight.... And there are plenty of places you are not allowed to(or shouldn't) collect fuel, like high alpine environments or arid regions where the vegetation is scarce, or in more populated parks with heavy traffic.

@Jms200013 3 года назад

That’s a good question, I reckon it depends on your stove first and foremost. Also depends on wind and other variables but I think medium high is most efficient as you won’t be losing water boil temps through the atmospheric temperature around you. Aka, faster the boil the less heat you lose through a slow boil.

Any thoughts on how altitude might affect these calculations? At 10,000 feet, water boils at 194f, so it might take less fuel to boil. However, combustion might be less efficient due to reduced atmospheric oxygen.

@martinpahl5652 Год назад

Nice video, but one fallacy here: The pressure in the canister does not continually decline. Most of the gas is in a liquid state and compensates for use of gas by some of the liquid turning into gas to compensate for the pressure drop. The effect of lower pressure when the canister is empty is caused by a drop in temperature. A liquid evaporating uses heat, so the temperature of the gas is lower than the liquid. The pressure of this gas/liquid system is lower at lower temperatures. If there is still a lot of liquified gas in the canister the sheer amount will compensate for the temperature drop. When the canister is nearly empty the temperature can't be compensated and you get the typical " cold canister"showing it will be empty soon.
