There are a couple of concerns I have about this but they are possible to overcome. First the video concept:
Here are my concerns:
First, he has put a copper coil around the stovepipe. The idea is to circulate water through the tubing to heat it. You probably won’t need a pump either because the hot water would rise to the top of the storage tank, automatically forcing cooler water from the bottom of the tank to replace the water leaving the coil. It all sounds good but the problem is the possibility of the water boiling, turning to steam, and causing an explosion. A pressure release could prevent this but the steam would have to be routed outdoors or somewhere so no one would get burned.
Second, the chimney gasses would naturally be cooled. Cool wood stove gasses will adhere to the walls of the chimney and eventually will catch fire. This is called a chimney fire and it’s a dangerous situation. The solution would be to run the stove in the bypass setting for a half-hour or so every day or two with the draft open to provide an extra hot fire. This could burn the solids off the inside of the chimney before they accumulate to a dangerous level.
Otherwise it looks like a good concept. Does anyone else have any thoughts?Share
