Dubbed the Inferno, this add-on for the Ti-Tri is especially made for wood burning. It takes the cone a step farther, into double walled construction where preheated air re-enters the fire box for secondary combustion. This means a faster more complete burn. Other double walled stoves I’ve tried include the Bush Buddy Ultra, Sierra Zip Stove and the Bushcooker Lt II.
My previous review of the Caldera Cone Ti-Tri vs. the Sierra Zip Stove found the Cone, although much lighter, required too much attention to keep going and was slow at best. Those problems are solved with the Inferno add-on!
Inferno add-on components:
1. An inverted smaller cone that fits inside the original cone.
2. A wire grate for the bottom of the fire box.
3. A small wire stand for the above mentioned grate, to allow airflow.
4. A circular piece of titanium for use as a fire pan, to protect the ground
Add-on weight is: 1.75 oz. The original Caldera Cone Ti-Tri (with 2 titanium tent stakes for pot supports) weighs 2.3 oz., for a total of 4.05 oz. Bush Buddy Ultra: 4.9 oz. (a complete matrix of wood stoves here).
With this add-on unit in place I had absolutely no problem keeping the fire going. In fact, once I loaded it with wood, I could walk away while it boiled a liter of water unattended. And it was fast too. My backyard test, from cold stove to boiling 1 liter of water, gave me a time of 10.5 minutes.
There are a couple of things though. Like, this is a prototype that’s never been offered for sale from Trail Designs, makers of the Caldera Cone. The Beta testers didn’t think it was worth the extra weight and fuss factor. The guys at Trail Designs sent me this unit at my request after I heard of it’s existence. It had been designed especially for wood, my fuel of choice. Maybe, if there’s interest, they’ll make it more widely available.
Another thing is the thin foil material is sharp and, after a few fires, dirty. Could be a problem inside the pack. They thought of this and designed a carrying case that works great. But, it adds another 2.25 oz. to the package. I store mine in my big plastic drinking glass, so no additional weight for me. The carrying case is pretty trick though.
The CC TT Inferno is the most stable of the wood burners I’ve tried. It can act as a food and hand warmer at the same time. Multi-use is always a good thing.
In the end, I still like the Bush Buddy Ultra the best. It’s simpler, uses less wood and is more compact. But I found it too small for more than 2 people. On the other hand, the CC Inferno has no problem with multiple pots of water. I’ll be carrying it on outings where there’s a crowd. As in, three’s a crowd. Or four… Not as wildernessy for sure, but still fun.
Here’s a couple of my amateur videos showing the process. The first one is short, showing just the set up.
The second longer one shows starting the fire and the burn.
