Caldera Ti-Tri Stove

Following the Caldera Cone success, Traildesigns (the folks that came up with the Caldera Con alcohol stove) came up with this brilliant cooking system. There are few things that make the Caldera Ti-Tri stove so great:

To begin with, they took the basic principals of the Caldera cone and made it of Titanium (Hence the Ti). It enables it to run on wood. Why is it that great? Because you always have the backup option of using the stove with simple wood you gather on the trail.

In addition, they also give you the option to choose between a simple wood-burning stove and a wood gas stove.

The design of the cone and the way it holds the pot is the heart of the system. The cone functions both as a windscreen and as a pot holder. You get a structure that uses all the heat for heating and almost no heat is wasted.

On its alcohol mode, since the pot is completely kept inside the cone, every bit of energy is used for heating up the pot. Keep in mind, though, that on its wood burning mode, the pot is held up high by two metal stakes and most of it is out of the cone. It reduces the efficiency a bit of course. You have to raise the pot so you’ll have enough room for the sticks and twigs you burn.

The cone got holes on the bottom to enable just enough air to support the flames inside. On the top, the cone got holes to enable the hot air to rush out of the cone.

It might sound ridiculous, but the holes are the  tricky part if you try to build it yourself. Too big, and you get too much wind and heat might be wasted. Too small, and the flames won’t have enough air to burn.

Multi fuel stove

Traditionally, we usually call a stove multi fuel if it can run on several benzine-based fuels (white gas, unleaded, etc). Now, Traildesigns claim (and I fully agree) that their Caldera Ti-Tri stove is also a multi fuel backpacking stove, but not in the tradition way. Why? Because the Caldera Ti-Tri stove can run on alcohol, wood or Esbit - hence multi fuel.

Moreover, you have two options to use wood - straightforward or with the inferno which turns the whole setup into a wood gas stove.

Using the different fuels

Ti-Tri as an Alcohol stove

On the alcohol option, the Ti-Tri works exactly as the original Caldera cone - Great. You use just the cone and the burner that comes with it. The pot fits right into the cone and only the lid is kept outside. The pot is completely surrounded by the cone so no heat is wasted. From my experience, you can use other alcohol burners too.

More here on the original Cone which is pretty much the same as running the Ti-Tri as an alcohol stove.

Ti-Tri as a wood burning stove

If you want to use wood with the Ti-Tri, you simply put up a miniature campfire in the cone. The pot seats on metal stakes you insert into special holes near the top of the cone. It is not trivial to set up this fire but after several times you’ll get used to it. Naturally, this option is not as efficient as the alcohol or as the wood gas option. On the other hand, it doesn't require additional parts (apart from the stakes), and it’s a great option to have as  a  backup. OR - you can have it the other way around - use wood as the first option and have alcohol as the backup...

Another great way you can use the Ti-Tri with wood is this option. You add some parts to the basic cone and you get a nice wood gas stove. The core of this feature is the inferno, an upside down cone, slightly smaller than the outer cone, placed inside the main cone. It enables the air to run in the typical way of wood gas stoves.

The inferno option is more efficient than the simple wood burning option.

Caldera Ti-Tri stove variants

Classic Ti-Tri

The basic one. Weighs 57 to 177 grams, depends on what size you get (to fit your pot).

Sidewinder Ti-Tri

For wider pots, and you can store the whole kit laying sideways in the pot.

On the sidewinder, you get a nice tradeoff between size and efficiency. On the one hand, it is tall enough to keep the pot inside the cone. On the other hand, you can fold it so it will fit inside the pot sideways if your pot is wide enough. Here too, by the way, the pot is standing on the stakes if you are using it with wood.

Weighs 71 to 104 grams.

ULC Ti-Tri

ULC stands for Ultra Light Compact.

The big idea is the same as in the classic Ti-Tri. They just made the ULC a bit shorter so you can fold it nicely and store it inside the pot you are using. The problem is, that since it is a bit shorter version, the pot can’t be totally submerged into the cone, and the whole system isn’t as efficient as the other Ti-Tri systems. On the other hand, if you are trying to save every bit of space, it does help.

Weighs 47 to 128 grams

Bottom line

Great Product! I really like it as an alcohol stove and use it a lot. I find the inferno option a bit tedious to assemble. I think the simple wood burning option is sufficient and doesn’t involve as many parts as the wood gas option. On the other hand, if you are looking for a backpacking wood gas stove - the Ti-Tri is a good choice.
