Envirofit's G-3300 Wood Stove

G-3300 Stove with Flexible Pot SkirtG-3300 Stove with Flexible Pot Skirt

This is a pretty straight-forward, efficient wood cooking stove, with a rest in the front for loading stick wood. It's pretty nice looking, and they've worked with Oak Ridge Natl. Labs to create a durable combustion area.

It's got a couple of neat accessories. The one on the picture above is a flexible pot skirt. Pot skirts do a wonderful job of increasing heating efficiency, but they can be hard to implement because not all cooking pots are the same size. This solves that problem simply, and it looks nice which as we know from user feedback is critical to stove success.

They have a chimney attachment which adds another "burner" to the stove, and helps vent smoke more efficiently.

Spec sheets and manuals are on their web site:

Envirofit's CH-4400 Charcoal Stove

Apparently this is all the charcoal cooking stove. It is designed to be one of the cleanest burning stoves available. At first, I mistook the tall top part to be a cooking pot, but instead it is part of the stove. According to the instructions, the user needs a combination of charcoal and wood sticks or chips, that are loaded into the bottom of the stove, then the upper part with the pot skirt allows the stove to burn more efficiently. There are attachments for the other version of this charcoal stove that allow for grilling. This one seems more optimized for pots.

Dear Stovers:

I am attaching [the image above]that may be of interest to the stovers.

Here is an unsolicited commentary on our new XL WoodGas Stove, available at

along with our gasification books.

We have recently learned that BP is manufacturing a VERY similar stove
and selling them (only in India) in their equivalent of Walmart. I hear
they have already sold 100,000. Sounds like we are well on the way to
getting a "Billion Improved Stoves" out to the developing world.

If you cover the combustion air holes with aluminum flashing or sheet
metal screws the stove also makes a good gasifier.

Onward,
