Hello all.
I just finished my rocket stove. I test burned it for a week in my barn and got great temps. My design was created by resourcing here at permies and other sites. It does a great job of heating and wanted to share it with everyone on this site. Here are a few pics and a short movie.

looks good! have just finished my first rocket stove out of scrap etc burns really well considering the riser is just wrapped in ceramic header wrap 2/3 way up.... where have you let the flue end? just out the window or up higher?

Is this an all-metal rocket heater?

It is all 1/8 inch by 5 inch steel tube. The riser is insulated with 5 inch wide fire brick from the bottom of the J tube to with in 1 1/2 inches of the top. The barrel is a LP tank I salvaged from the scrap yard. So is the 5" tube. The exhaust is 6" from tractor supply. I have it running out the window temporary to make sure all is ok before putting a hole in the wall. I did have to make the exhaust stack 14 ' high due to the steep pitch of my roof, it kept back drafting. All in all it works great. The only draw back is I have to fill it every 30 to 40 minutes due to the size of the burn chamber. Plan on extending it soon. For now it's heating about 900 sq ft of my home and keeps it about 76 deg with the lid 1/8 inch open and the front breather holes wide open. The temps at the top of the stove are ranging from 400 to 550 deg. I picked up a ecofan 810 yesterday to set on top the stove and tried it last night for about 2 hours but had to shut it down due to it was hitting 80 deg in the house plus it was bed time and I don't run it then. It's a great project. I spent about 2 months researching on this site and all over the net to get my plan together. It's made from so many peoples suggestions that I can't remember them all. And by the way my wife loves it.
One more note: the band in the middle of the stove is a big band clamp to I can take the top off to clean it out which I did this morning and it makes it so easy to clean it took about 20 minutes but really was not dirty. About 1 1/2 quarts of ash after burning for about 35 hours. Hope all this helps.
Merry Xmas to all.

Bill, the fire brick is inside the metal? Or outside?

Anyway, metal in contact with flames is doomed. And if your firebricks are not the white insulating firebricks, they don't insulate

The fire brick is on the outside of the 5" riser on all four sides, it's held in place with 10 " stainless steel hose clamps so the heat does not effect stainless like regular hose clamps. I got a kit to make what ever length of clamp I want from Fastenal. It was about $60 for the kit. It comes with about 50 feet off band material and 20 male and femal ends so you can make what ever you want. Just snug it down. I also did this so if I had an issue with the stove I can take it completely apart. Any more questions let me know or I can post my cell # or email if you like.

Have a great day
