rocket stove how to

We have a greenhouse "already built" and we are adding onto it. We are interested in the rocket stove aspect but wonder how it would work. The addition of 12 foot would be added to the west side of the greenhouse. How would we construct the rocket stove as to not burn the new wall. Do you have to put a heat barrier wall where you are putting the rocket stove and lounging area???right up against the new extended wall or inner greenhouse wall? thanks, sure do enjoy watching your videos Mearie

Hello Mearie,
Greenhouse plastic is definitely heat sensitive, so I would allow a little extra room compared to a normal wood or drywall combustible wall. Many folks build a raised bed in the middle and run the rocket heat though this, so it heats the greenhouse evenly.

If you can tolerate reading some draft building code, take a look at this page for clearances that are recommended in most situations: http://www.ErnieAndErica.info/rocketmassheaterpermitting
The barrel will be hottest, and there should be good clearance around this and the fuel feed, for both plastic and plants.
