Soto Windmaster vs BRS 3000T and Heat exchanger vs regular pot.

[Marbles]

Gotta chop those BRS legs down so the burner sits just up under the bottom of the pot.

I don't think it can be made comparable to the Windmaster, in part because it is the Windmaster's wind shield and not the burner that makes it sit fully inside the heat exchanger.



I think the BRS would work better cutting down the pot supports, but I'll have to think on it before possibly destroying it.

A small windshield around the BRS burner is more interesting to me at the moment.

Doesn't have to go as high as the WM. If chopped like in the photo the burner head sits just above the bottom of the pot and just out of direct wind. May not be as perfect as the WM in a heavy wind but definitely better than stock. They are cheap enough so who cares if you F one up? Get another one

@Marbles
I only briefly glanced over, but I didn’t see a test with the BRS nested inside the Fire Maple with no wind. That is how I use mine, as I never try and use a stove in the wind, no matter which one I’m using. It’s always in my vestibule.

As I expected, in no wind conditions the BRS was more efficient. The Fire Maple pot doesn't appear to add much to the Windmasters efficiency in no wind.

BRS with Fire Maple, no wind
Start temp 68.9 F
Start weight 233~ g
Time 2:36
End weight 231~ g. = 2 g

Soto with Fire Maple, no wind
Start temp 61.7 F
Start weight 271~ g
Time 1:39
End weight 266~ g. = 5 g

Soto with Fire Maple, no wind, lower heat trying to be more efficient.
Start temp F
Start weight 266~ g
Time 3:02
End weight 262~ g. = 4 g

Of all the things I try and cut weight on, I never skimp on stove fuel. I will gladly carry a larger or extra can of fuel vs. cutting it close on fuel.

I've never done a test like this, pretty informative with how you did it. Thanks

For light weight, if counting on shielding wind, the Toaks 650 ml and BRS come out ahead.

I'm going to over complicate things for thought experiment purposes. I don't want to think about changing out gear all the time.

Also, note the math is not linear for adding volume (should be more efficient per ounce of water as you boil more at once). This is a thought experiment for illustration purposes, it would take more testing to get operable conclusions.

A small isobutane canister holds 110 g, meaning the BRS gives 36~ 8 oz boils with the Toaks, 55~ 8 oz boils with the Fire Maple. Given the lack regulator, probably closer to 30/50.

If one needs 32 oz boiled per day, the Toaks wins going for a 7 day trip.

The Fire Maple could get 12 days.

If you figure 3 days fuel reserve to allow for wind, temp, Etc, then 4 day or shorter trips the Toaks wins.

4-9 days the Fire Maple and small canister wins.


227 g in a large canister.
-BRS + Fire Maple = 26 days
-BRS + Toaks = 17 days

So, still giving 3 days reserve the Toaks wins for 10-14 day trips and the Fire Maple for 15-23 day trips.

You figure 5 g per 8 oz boil with the Soto, irrespective of pot.
Small canister = 22, so 5 days if needed 32 oz per day.
Large canister = 45, so 11 days.

Now, add wind and the Fire Maple and Soto Windmaster becomes more efficient.
