Building a Rocket Stove in Our New Greenhouse

Here is a video showing our experience with building a rocket stove thermal mass heater. It shows our problems and temporary failures, as well as our successes. The main difficulty, or what made a simple technology a little more complicated, was a particular innovation that my son, Noah, and I tried using an old metal mailbox as the wood feeding chute. We did that because we wanted to feed the fire from outside to prevent the greenhouse plants from getting too much smoke, in case of backdrafts, or any other possible malfunctions with the stove. That put the wood feed back about 10 inches to a foot further away from the heat convection barrel than what we have seen on most rocket stoves on the internet, which caused the fire and smoke to backdraft on us a bit for awhile. But, as you can see in the video, we came up with a solution and it worked just fine in the end.

  1. I am looking fwd to seeing how this works after you get some plants going. Keep us updated please, obliged.

    • Hi, Dan. Just thought I’d give you a little update on this. We decided to not run the stove this Fall and Winter, but wait instead for late Winter/early Spring to start the plants for the new season. we do have some potted trees in there for the winter, and since they are dormant, we think that they will do fine in the greenhouse without running the stove. I’ll update you again sometime in March. Blessings and peace to you and family.

      • Thanks for the update. You never know we just pop by someday soon. We may be going up past Spokane soon and were thinking about popping by your place for lunch. Will let you know. Blessings.

  2. Will do, Dan. I just finished building the shelves today and we have had trays of starter tomatoes, onions, kale, and other things in there for about two or three weeks now. I have some tree starts going in there, too. With the outdoor temparatures in the 70s, it has been getting into the low 90s in the greenhouse, even with both doors and all four windows open. We’ll probably have to start running a fan in there, too, pretty soon. Probably won’t stoke up the rocket stove again until September, unless we just feel like doing a short test run sometime.

  3. We would love seeing you and Lynda anytime, Dan. I work at home on Tues., Thurs., and weekends. If you are in Missoula on Mon, Wed., or Fri., my office phone is (406) 243-2302. I still don’t have a cell phone.
