What did you end up using to insulate the riser with?

I have been kicking around something similar for some time.  Most of the rocket stove examples out there don't use water (or at least on this scale) due to the need of electricity for motors.  At least that has been my take away.

I did find one guy with some YouTube videos of his magazine fed rocket stove/water heater that he runs through a heat exchanger for heat in the house.

Digging through his YouTube page he has a couple other videos on his setup also.

On damping the air so it can be idled, the only hard numbers I have found on the effects of doing this indicated that damping the exhaust kept the highest flue temperatures.

The test where done on a cook stove and not a heater so not sure how that will affect its temps, or its draw.

I am all in on your stove, and like the rest, anxiously wait to see this come to life.
