Well, Saturday. Time to get out on the trail! :) I'm looking forward to testing a new wood stove.
Arriving at the creek, I see some recent blow down. The fuel depot is open. :)
It only takes a minute to gather enough wood for a wood stove, a distinct advantage to using a stove over an open fire.
And today's stove? The BushBuddy Ultra.
The first thing to note is that a BushBuddy Ultra is a tall stove. You'll need a pot with some height in order to be able to put the stove in the pot.
Here, I'm using a Snow Peak 1000ml pot which has a frying pan type lid. Without this lid, I couldn't store a BushBuddy Ultra inside a pot with these proportions.
A BushBuddy Ultra pretty much needs to be stored upright. It won't even begin to fit in my pot sideways.
A wide, short pot without a frying pay lid may have trouble accommodating a BushBuddy Ultra. For example, an Evernew 1.3L pot cannot hold a BushBuddy Ultra. You really need a taller pot.
Neither can you lay the stove on its side.
Well, let's pull that BushBuddy out of the pot and have a look. The pot support cleverly fits upside down inside the body of the stove.
Note the grill in the above photo. This is important. The grill keeps the wood off the floor of the stove, allowing air to flow up from underneath during a burn.
Pulling the pot support out, I notice a row of vent holes just below the rim of the stove.
There are more vents on the outside at the base of the stove.
Basically, the BushBuddy Ultra is a chimney type stove. Cooler air enters from outside at the base, is heated between the inner and outer walls of the stove, and as the air is heated, it expands and accelerates out the ventilation ports just below the rim of the stove in the interior, causing a strong inflow of oxygen rich air. It's a pretty good design. Someone obviously knew what they were doing.
The pot support rests on the rim of the body of the stove.
The pot support has a gap in it that can be seen at the left in this photo. Additional wood can be inserted through the gap during use.
Taking a step back from the details, the first thing I notice is the craftsmanship. Everything is really well made and well put together. Just look at how regular the pattern of the spot welds is on the bottom of the stove.
This stove is not something that someone just slap dashed together. This is a well thought out stove with truly excellent build quality. A lot of labor clearly goes into the manufacture of these stoves.
Well, let's fire her up!
Today, I'll be testing with a 1.3L Evernew pot with 500ml of cold creek water.
A 1.3L pot like the Evernew is a little bit wide for the BushBuddy, but I found the BushBuddy to be reasonably stable. I was careful to pick fairly level ground.
One thing I notice with a BushBuddy Ultra is that it's a little hard to predict where the flames will come out. This make it a little tricky to keep the pot handles out of the flame. I found that by simply watching the burn and periodically repositioning the pot as needed kept the pot handles reasonably cool.
The other thing I found during testing was that one load of wood wasn't enough to boil 500ml of cold creek water. I had to reload the stove. It's possible to insert some wood through the gap in the pot support.
However, to really get even loading, I found it easier to remove the pot. If one is inserting wood through the gap in the pot support, it's important to watch the ends of the sticks you insert. Burning bits can fall of the ends of the sticks.
When additional wood is inserted, the excellent ventilation of the BushBuddy Ultra quickly causes the additional wood to become part of the fire.
I didn't time it, but I was quickly able to get a good boil using the BushBuddy Ultra.
Now, here's one of the nice things about a wood stove: There are more heat settings than just "boil." I let the wood burn down to just coals.
Then I add my noodles.
I add a few dried vegetables.
And a few minutes later, everything has re-hydrated nicely.
And the best part? No scorching, and no burning. It's wonderful to have multiple heat settings on a stove.
And after the burn? Nice, complete combustion.
In short, the BushBuddy Ultra is a really nice wood burner. It has a fairly small combustion chamber, so you do have to add wood while a boil is in progress, but no big deal.
Of course, there are times when you can't burn wood every meal. For example, sometimes fuel is scarce (or wet) or perhaps you're at too high of an altitude or perhaps you're in such a popular area that wood fires are restricted. Whatever the reason, there are times when wood fires just aren't going to work out. With the BushBuddy Ultra, do you have a plan "B?"
To find out, I thought I'd try a quick experiment with an alcohol stove.
Using a Trail Designs 12-10 alcohol stove and 0.75 fl. oz. of SLX denatured alcohol, I thought I'd try to boil 500ml of cold creek water.
Normally, I'd expect 0.75 fl. oz. of SLX denatured alcohol to bring 500ml of cold creek water to a boil. It didn't.
I added an additional 0.75 fl. oz. of SLX denatured alcohol and re-lit the alcohol stove. This time, toward the end of the burn, I got a boil. Not a strong boil, but the water did boil.
In other words, it took 1.5 fl. oz. of SLX denatured alcohol just to get a rather uninspired boil. So, do you have a plan "B" with a BushBuddy Ultra? Well, yes, but the BushBuddy Ultra really isn't an alcohol set up. The BushBuddy's strength is wood burning. While the BushBuddy Ultra can be run on alcohol, it doesn't work all that well. The BushBuddy Ultra is a wood burning stove and is best used for that purpose.
I didn't get a chance to test with hexamine (e.g. ESBIT), but I believe the results will be similar to running with alcohol. The best use for a BushBuddy Ultra would seem to be for trips where you can almost always burn wood and then go to a secondary fuel only if you really have to.
Are there other ways to use the BushBuddy with non-wood fuels than what I've shown? Of course, and I think they're worth exploring. However, a simple substitution (as done above) of an alternative fuel did not produce good results. Got a better way? Lay it on me. :)
CONCLUDING REMARKS
Cooking with a wood fire using a stove is so much easier than using an open fire. There's also much less chance of starting a wildfire given the contained nature of a wood stove and the complete nature of the combustion, and there's very little trace left when you're done. Having tested a couple of wood stoves now, I really wouldn't consider going back to an open fire for cooking except in an emergency.
I have to say that it was a real pleasure to be able to use a BushBuddy Ultra. Special thanks to Christian D. for the loan of his BushBuddy Ultra for this testing.
Thanks for joining me for another Adventure in Stoving.
