For any of the people who has been designing and working with these creatures. What have you been doing to design a stove with the intention of coding in mind? As a product that is superior in design to most any wood burning heaters, has any effort been made or currently being made by anyone to design a code approved stove? It seems like the next logical step is to have a code approved option for many alternative building features, ie: cob and straw and many other non approved yet sound building designs. I understand the reason for building codes (safety) and also understand the problems with building restrictions in a residential setting(expensive). As the poor are often left with debt as there only solution to finding housing, that is there own, the building code are restrictive to cheap building design and construction. It sems that the goal would be a UL approved design for a rocket stove.

I spoke with UL via email and phone these past 2 weeks to get a Rocket Mass Heater certified as my county will not allow a non-UL approved appliance to be installed. I had to submit basic plans and a description. They replied with a cost of $4500.00 to certify my individual stove for my residence.

My county later said they may approve of a permit if I have a thermal transfer engineer approve of my plans. I am still waiting on an answer from them, since they never heard of it and had to do consulting and research.

Erica and Ernie have produced some plans, I think with the hope that someone will eventually be able to get them through the coding process.

Here's the link to their store - http://www.scubbly.com/store/ernieanderica/ and direct links to the 8" system and the 6" system

I appreciate the info. I have seen that they have plans available. I plan on doing mine a little different. I have an old air compressor (I think it will look better than a barrel) that I'm going to cut, install the J-tube, then weld back together so it's a sealed unit. I also plan on a fresh air intake as opposed to drawing room air in.

Yes, I planned on putting an access port either at the bottom of the tank or where the exhaust leaves the tank. It will also have an access door for starting the fire, and another for loading.
