Hi everyone, my rocket stove has been busy all summer collecting dust, that is until the temps dropped to 27F. I'm super pleased with my riser modifications I made last season. The stove comes up to heat much quicker with the newly installed ceramic fiber board . I can come back a couple hours after the fire has died down and get a quick start up by dropping in fresh wood on the remaining coals. It looks as if the riser will stand the test of time, of course only time will tell. I don't think I've shared my flue setup, so here it is. I have a transition coming off the heat exchanger that has a 7" pipe attached, it makes a 90 degree turn and reduces to 6" pipe running 16' on an angle up and around to the ceiling. Then it reduces again to a 5" double wall pipe that runs vertically 15' through the roof. Progressively reducing the flue pipe size and using double wall pipe allows the system to run at a lower stack temperature without having issues with condensation. This is a link of my stove in operation. youtu.be/_fjrwNuEF_s

I watched your video, very interesting design, do you have a build thread? PS that is a very small screen video :-) Your riser looks neat too.....

Hi Martyn , I apologize for having my phone turned the wrong way! I don't know what I was thinking. Maybe I can get a better one made soon. Sorry I don't have build photos. My riser is nestled inside a larger stainless pipe that's insulated as well. Each strip is cut in a triangle form so they hold themselves in place. It was a little tricky getting the last one in, but it wasn't bad. Believe it or not, I made a jig that holds a box knife blade and use the table on my diamond saw to cut the triangular shape of the soft ceramic board.

Great technique for making a ceramic-lined riser out of stiff ceramic board, I also liked your relaxing music for the video.

One year in and it still looks new. I tried using the prepackaged fire mortar( the black stuff that comes in a tubb) . That was a total waste of time.

Looks nice with the glass cover and being able to see the fire.

The best trick in my bag was cutting a sheet of 2'x4' ceramic board to make the riser with close to zero waste.
