And we do have a double skinned chimney – at least, a liner inside the outer.Martinhttps://www.blogger.com/profile/08084401790316697529noreply@blogger.comtag:blogger.com,1999:blog-2576670202526573146.post-38142162535893236892016-10-10T21:28:24.975+01:002016-10-10T21:28:24.975+01:00I believe a colder external temperature should hel...I believe a colder external temperature should help the draw, not hinder it, as long as it's not too cold in the boat. The bigger the temperature difference between inside and outside the better the draw. What you're really after is a good temperature difference between the gasses in the chimney and the air outside it. The lighter hot gasses will rise all the more readily in this situation. This is why a double skin chimney - for more insulation is a good idea.Halfiehttps://www.blogger.com/profile/00167481543065324357noreply@blogger.com
