sub floor rocket stove and bypass

we are building it this weekend if any of you folks near portland are interested.
this is not a class its just building and testing so i dont expect folks to show up in a work shop frame of mind. Erica and i wont be; we will be in stove design mode and will answer questions but wont be doing any lengthy explanations.

send us an email and we will send out the directions and contact stuff.

Got some good photos. its all laid out and ready for the build tomorrow. we will test fire it before we put any mass on the system to see if the bypass valve will work as we think it will. it will be a great thing if this all works out. Tired  time to sleep.

Looking forward to the reports. 

I found myself daydreaming about rocket stoves and radiant floor heating yesterday.  Wonder if anyone has attached a closed-loop fluid system to a rocket heater? 

as far as i know not yet, the calculations needed are how much mass the closed loop system has. flowing water makes things a bit tricky because your mass is laid out differently. you cant add mass to the system with out figuring both the static and the active and getting the balance right. Erica and i are crawling in that direction as far as the math and such goes. however we wont do it if it cant be done from scrap materials.
I am not comfortable using active things in these systems if the circulation cant be done with a thermal siphon then we are not going to do it. the point of rmh is to have it do most of the work so you dont have a way for it to fail. My own thought is these are not pellet stoves that only work when the power is on.
