<br/>
Our colleague's question was locally based and not calling into question whether in the world somewhere clean burning chimneyed stoves are produced. It is a well-established fact here that that is the case. Many stoves both with and without chimneys have good, _clean_ combustion. I also consider it as well-established that your belongs to this latter group! :D<br/>
