Hello all. I recently built and as of lest weekend am now running my second RMH. I have found, as most have, that cold start can be challenging. On my second build, I have incorporated a 1" iron pipe running into my chimney cleanout and then up my chimney to just under where the horizontal pipe from the stove enters the chimney. On this pipe I have mounted with a air mattress fan that, at the flip of the switch, blows a small fast stream of air up the chimney causing a venturi effect and drawing from the RMH. Once fire is started, up to a minute or so, the pipes are filled with warm air and the pump is turned off. Since there is no creosote anymore, I don't see any future problems. If this picture thing works you can see where the pipe enters the clean-out in the wall. The clean-out is sealed also so no leaking. I hope this can help someone.
Hi Brad; Great idea looks like it works well. Now for you or another .The draft WILL improve after you cover your pipes and layer your mass . Then the whole thing must be completely dry (weeks) only then will your air supply become unnecessary ( but could come in handy on a windy day). Believe me there is nothing easier than lighting a rmh . Very first fire of the season in an already built rmh will start rite up. Succeeding fires you will have trouble keeping your match lit long enough to get it in the feed tube. On a wet build expect smoke out of everywhere and the first fires to fight you for days but after it all drys and heats then the real beauty of a rmh shines .
