I am planning on doing this for my house. Have all the pipe and firebrick. Will be putting the stove part together this weekend - then plumbing the pipe. I dread building the thermal battery as it will be in the crawl space! I plan on incorporating the bypass that you show I the video for initial startup - then gradually wean over to main thermal battery...
What kinds of issues are you experiencing and how do you recommend overcoming them?
Thanks!
