layton Posted June 10, 2010 Share Posted June 10, 2010 I tested the Soto stove with a titanium pot which is supposedly the best lightweight canister stove (it has a regulator to conserve fuel and help with cold weather operation), the MSR Reactor, and the JetBoil. I timed how long it took to boil one liter of water on each stove, and timed how long it took to run out of 100g of fuel. I then divided the two times to get how many liters of water the stoves could boil with 100g of fuel (the small canisters). The flaw in my test is that the stoves may perform differently depending on how much fuel is left and how long they were running for. The best way to do it would be to individually boil each liter of water, turning the stove on and off (letting if cool) each time. Also, I had each stove on full blast. The reactor seems like it doesn’t waste fuel based on how high you turn it up, but the other stoves may. They could be at a disadvantage in this experiment due to this fact. Here are my results: Observation: The Reactor seemed like it burned the hottest and the most consistently for the life of the cartridge. The flame seems way more evenly distributed than the pinpoint heat of both the Soto and the JetBoil. Also, the pot is wider so it get more surface area heated. It clearly wins the contest as the quickest boiler. The Jet Boil surprised me by being only 4oz lighter than the reactor and taking much longer than expected to boil a liter of water. Since it is thin and tall, boiling less water more frequently may conserve more fuel. However, it would not die. The burn time was incredibly longer. The Soto packs a little punch, but it died out the quickest. I was really hoping it would outperform in cook time, but it didn’t. Data: (weights are of a 600g scientific scale, boil time is time it takes for the 1st large bubble to hit the surface on 1 liter of water at 32degreesF, burn time is until the flame went out on a 100g canister). Reactor Weight=17.2oz(stove,pot,lid) Boil Time=160sec Burn Time=2920sec Liters boiled/100g=18.25L Jetboil Weight=13.3 (stove,pot,lid,cozy) Boil Time=263sec Burn Time=5360sec Liters boiled/100g=20.4L Soto Weight=6.24oz (stove, titanium pot, lid) Boil Time=270sec Burn Time=2520sec Liters boiled/100g=9.5L 4oz (110g) MSR isopro bottle=6.5oz* 8oz MSR isopro bottle=12.5oz* *weights taken from the internet, not confirmed. Conclusion: It would be nice for someone to help me figure out the break even point where it would make sense to bring the heavier more fuel efficient stove. I’m not very good at this type of math – I’m sure I could figure it out, but I’d question my numbers. Other numbers to figure in are the different weights of a 4oz vs 8oz fuel bottle since it is slightly lighter (but not much) to bring an 8oz bottle. The JetBoil wins in the most efficient stove, boiling 20.4 L assuming the heat output is the same throughout the test. The Reactor was close behind by about 2 liters less. However, based on pure observation, I’m thinking the Reactor may actually win since it burned consistently hot and boiled water so damn quick. It wins the user friendly test by it’s absurdly fast cook time, and it’s higher volume capacity. I wish MSR would make a limited edition titanium reactor stove! The Soto stove (and perhaps any lightweight stove) wins if you are not going to use up a fuel canister. It could actually win the efficiency test for a couple fuel canisters worth just because of how light the system is. It would be awesome if some mathy-type person could help me figure this out! I will published the results on my website and hopefully put them in a 2nd edition of my book. Quote Link to comment Share on other sites More sharing options...
