Dragon Heaters Vs. Rocket Mass Heaters

dragon heaterDragon heaters offer more efficient heating, in a smaller footprint, with more flexible design options. Our goal with Dragon Heaters is to bring Rocket Heater concepts to everyone, by simplifying the build, improving aesthetic choices, offering a range of heat storage approaches and reducing its footprint.

The traditional rocket heater was developed and described by Ianto Evans and Leslie Jackson in their book Rocket Mass Heaters. Dragon Heaters differ from this approach in 2 key areas: the combustion area and heat capture options.

The Dragon Burner is made with optimized materials and a complex shape that is more efficient and has fewer emissions than a burn tunnel built with bricks.

Flexible heat capture is the other main difference. The traditional rocket heater uses a steel barrel for immediate heat and a clay bench with an embedded flue for heat storage. Using the same J-tube style combustion system, Dragon Heaters facilitate more options for utilizing the heat. Users can select to release it all immediately, only some, or put all the heat into thermal storage as in a masonry heater.

Having a pre-built combustion system frees up many of the design constraints associated with traditional rocket heaters. For example, it is possible to build a heater which radiates a portion of the heat into a space and puts the rest into thermal mass, without either the barrel or a cob bench.

What is a rocket stove, and how do I build one?

A rocket stove uses a j shaped fire tube to efficiently convert solid biomass fuel (wood, biomass briquettes, etc.) into heat, with minimal emissions. A rocket heater adds an insulated heat riser, and a radiator, as well as a thermal mass for slowly radiating heat into the surrounding area. A inexpensive unit can be made from cans, or thermal mass units with concrete, brick or cob.

The Rocket Mass Heater

Want an extremely efficient, clean burning wood stove? Check out the Rocket Mass Heater by Ianto Evans and Leslie Jackson! A house that burns 7 cord of wood a season can burn just 2/3 of a cord with this style heater, as it burns cleaner, extracts more heat from the “chimney” without creosote build up (no chimney fires), and stores the heat in a thermal mass for gentle long term radiant heat, so the fire doesn’t have to be fed constantly. The best part? You build it yourself, and it’s very inexpensive. Learn more from the $13 eBook at http://www.rocketstoves.com/. We bought it, read it, and are starting on our stove. We recommend it.

Efficient Rocket Cook Stoves

The folks at Stove Team International are building healthier, more efficient cookstoves for 3rd world (developing) nations. These stoves are built upon the proven rocket stove principle, which combines clean burning with fuel efficiency. Here is their story, and you can see how their stove is built on their YouTube channel. Please support their humanitarian work!

Our Rocket Stove

I fired up the rocket stove and took some pics. Enjoy! We have these available, delivered, for $99 in the lower 48 states. Discuss these stoves at http://groups.yahoo.com/group/m1941/, and see the videos at http://www.youtube.com/view_play_list?p=C5513B49DCBA3830.

AIR-X Wind Turbine Arrived, More Rocket Mass Heater Videos

The 24v AIR-X arrived today, and the Whisper 500 watt unit arrived last week. The Whisper was donated by Jim Juczak of woodhenge.org. Allan Smith, the creator of the Rocket Mass Heater came for supper, and we discussed his design, and alternative implementations. We will be building one of these soon. A ebook of the heater with video and Sketchup diagrams will be available from us shortly, as well as one with the wind turbine setup and installation. He has also added a couple more video’s on startup of the heater, and heat circulation. The manual wood splitter mentioned in the video’s is found at Bailey’s Online.

Allan’s Rocket Mass Heater

A friend of mine just posted his working version of a Rocket Mass Heater on Youtube. This is a great example of a clean burning, extremely efficient heater that can be used for space heating, cooking, or heating water, or any combination of the above.

Making and Using Biomass Briquettes

A Biomass Briquette is a compressed brick made of agricultural waste, used for heating and cooking. It is very efficient, renewable, and carbon neutral. Common materials are sawdust, charcoal, grasses, and other biological materials. The following links will describe the process, and how to build your own press.

A rocket stove is a efficient way to use them. There are many youtube video’s on rocket heaters, and we have plans at http://www.green-trust.org/products/

More residents getting “sick” from wind turbines?

The residents of the town of West Lincoln, Ont.  are reporting a variety of stress related illnesses they attribute to a wind farm nearby.

“‘It’s too late, two years too late,’ said Helen Kzan … ‘I’ve been to the doctor. They told me to move. My stress level has skyrocketed. My physician told me my stress will kill me before the wind turbines.”

Many people attribute these illnesses to the reported sounds, vibrations, and light patterns made by the moving blades. What’s wrong with this picture?

The wind farm hasn’t been built yet.

These people are reacting to the anti-wind advocacy groups reports on what they think will happen. It’s not wind turbines that make you sick, it’s listening to the lies and made up statistics of the anti-wind groups.  It’s their own fears that are making them sick, and the anti’s are creating self fulfilling prophecy.
