Hi all.
Just a question.
How much fuel should I bring, for a snowpeak stove. Gone for 8 days. All breakfasts will just need about 3 cups boiling water. Dinners will need to be cooked.
More than 220g (ie small canister?)
Thanks

Don't know what a "snow peak" stove is.
My msr whisper stove used on a three day / two night, snow melting and food for Two {2}
used nearly 1400 mls { 1.4 litres } Very liberal useage. Mainly White gas. |

I'm going on a week long trip rather soon and my current plan is to bring two 220g canisters. I think it will be more than enough... but it really does depend on how much you use your stove (just boil water? or simmer for 10 mins? soup and hot drinks? or just the main dinner? etc.).
If you used gas at cambiums rate you'd need like 20 canisters or something ludicrous, but a) that was melting snow and b) the fuel consumption is ridiculous. |

My rule of thumb is 2.5oz (130ml) of fuel per person per day. add to this 1 oz per person per day if you are doing any extreme cold stuff. You will find this a useful formula especially in group scenarios.
This will allow for a hot breakfast and dinner and a cup or two of tea daily per person.
Assuming you are going solo you will need over 1 litre.
The 450g. canister will likely be enough if you are fuel efficient and avoid any fancy stuff. |

I only boil water and that is one boil in the morning for coffee and two boils in the evening for tea and a boil-in-a-bag dinner. From a propane/butane mix fuel stove, I use about 15 grams of fuel, per one boil, of about a litre of water, at summer temperatures, I can get easily get a 4 or 5 day trip out of a medium, 227 gm net, tank. In winter I will double my estimated fuel consumption, for melting snow or for heating really cold water and alter it to the temperature of the water I'm using at the time.
A trick to getting your best production from canister stoves in cold weather is to use a remote canister stove. When the flame gets whimpy, due to cold temperatures or low fuel, just turn the fuel container upside down and you'll get a hotter burn and it will burn to the end of the tank volume.
I usually only use the largest 450 gm net weight canisters and just keep using them untill they're out. I weigh them on a gram scale before & after a trip. That way I can keep track of how much fuel I'm using on recent trips and also keep track of how much fuel I have left for the next trip. Keep your own before and after trip stats with your fuel and you'll get a pretty good idea of how much you'll need for any given trip.
In the past, I would always second guess myself and take way too much fuel on trips and bring most of it back home again. I really hate bringing back unused fuel or food weight, if I don't have to.
Also, in he past I would start a new trip with a new canister and ended up with many part filled canisters. Just keep using a canister until it's empty and just keep track of your fuel comption and fuel left. Packing a nearly empty canister at the beginning of a trip weighs almost nothing. Packing several full canisters in and out adds up.

Yea , sounds like a lot, that was nearly 1 large cannister and one small cannister. That particular trip there was actually three in our group, but the useage was for two.
this was during the { upcoming again } Perseids Meteor shower, we were perched at the Frog ponds across the way from comox glacier. Not too high ,lots of snow melting draws a demand from the fuel needs. Really using the stove a lot. Trying to
avoid the red algae growing in the snow and super boil .
This location and time was prime for star viewing. I was feasting and drinking soups and hot chocolate like a true pig well into 2:00 or 3:00 into the morning, laying down and watching the heavens Great Stove. Good substitute for a hand warming fire. Ahh , if only I could return there. Lightly waking up in the a.m. to the sounds of passing hikers, fresh cool glacier breezes, and my brother gearing up for his glacier trip. Oohh , the roar of melting glacier across the way,what a sound.
... I highly recommend it for all of you, August 12 , look between casseiopea and perseus .
Good nite. |

... what a bummer, looks like this year's perseid shower was a " cloud-out ",every time I looked up
nothing but cover.
Oh well , like they say on the Island of Misfits, there's always next year... |

I typically go with 15g per boil as well for summer with a windscreen (0.8L or so), doubling or even tripling that in winter depending on how much I expect to melt. My weights for empty canisters if you're not working from full ones:
110 snow peak - 85g
220 MSR - 133g
450 MSR - 150g

Some points:
**The original poster has a canister stove, NOT a white gas stove. You cannot compare fuel consumption between the two.
**The original poster mentioned boiling three cups of water for breakfast and cooking of suppers. No melting snow, etc.
I have an oatmeal breakfast and a re-hydrated or cooked pasta/rice supper and for TWO people, one 225g lasts ~3 days.
Topic change:
As for white gas consumption on winter trips, for ski mountaineering trips where we use a white gas stove, (XGK) we carry one liter of fuel person per four days. This is enough for melting snow, cooking two full meals per day and a ton of brewing up. |

Most trips I use a Brunton Crux canister stove (very similar to the Snow Peaks stove) but on a remote Brunton burner stand that allows use of a full, foil windscreen (definitely improves fuel consumption). http://www.clubtread.com/Gear/productdetail.aspx?productversionid=799
I use Snow Peaks Giga Power 220 canisters. My summer fuel consumption allows 4 full days per canister cooking for 2 people as follows:
Breakfast: boil approx. 1 liter for oatmeal, coffee and clean up
Dinner: boil 500 ml for dinner and extensive simmer (Sidekicks meal) + boil about a liter for hot chocolate and clean up.
I can usually also sneak in an extra 2 boil/simmers of about 500-750 ml per canister.
So with careful use 2 x 220 g. or 1 x 450 g. canisters should do for 8 days (the quoted weights on canisters are conservative figures for fuel only: a 220 canister actually weighs about 380 g. and according to my scale provides about 240 g. of fuel) |

| On my Stein Traverse trip last year: 3 people, moderate use, a 220g canister lasted 3 days. It was a four day trip...oops! I am going on a 3 or 4 day trip with three people again in a couple weeks and I plan to take one 450g canister this time. |

Giga (a Japanese company) makes the snow peak stoves. They also make those awesome small titanium solo cooking sets. Most of their products are super light and compact. I highly recommend them.
The ammount of fuel consumption will vary according to which altitudes you are planning to do your 8-day trip (i.e. sea level vs. +10,000' boil rates are vastly different). I suggest you take your stove for an overnighter at the same altitude level (or slightly higher) than the highest altitude of your 8-day route if possible. Weigh your fuel before and after to determine how much was actually consumed and then extrapolate based on your actual consumption of the overnighter to account for 8-days and then add some leeway to account for any mishaps or extensions. That will give you the best approximation of how much fuel you will use. For 8-days I recommend going the dehydrated meal route -- 8 days of cooking food is a lot of weight in terms of food and fuel -- and only bring the water to just right before a rolling boil (i.e. lots of air bubbles just about to rise into a boil). Also, if you're at high altitude wrap closed-cell foam with ductape around your fuel cartridge -- this greatly improves the fuel consumption rate (this is absolutely necessary at very high altitudes). |

I use to wrap my canisters with ensolite, but in reality the insulation keeps the cold "in". As the gas evaporates from a liquid to a gas it becomes cooler. Then I tried wrapping a copper wire around the canister, under the ensolite, leading up to the burner, thinking that this would add warmth to the canister. I maybe helped, but not noticeably.
I sleep with a canister, so I'll have a good morning burn, but I find using a remote canister the best tip I ever got. When it's cold or the canister is getting low, invert it and you'll get a hotter burn. This works on my MSR WindPro, that has a pre-heat tube running along the burner. Stoves without this feature might flare up, so experiment in a safe place.
On fuel consumption... I just got back from a five day trip at about 1,500 metres and I used 223 grams of fuel, for boiling about 12 litres of water, or in other words, about 20 grams per boil.

| I usually count 6 meals per 220g canister, for 2 persons, in summer normal hiking. |

| everyone here seems to be talking about canister stoves. i haven't used one, i use a bottle, don't have a gram scale so its much easier to assess how much fuel is left. |

The original post was concerning a canister stove, so it seems that might be the topic... |
