We call it shock cooling in distilling . If you don't maintain gradual heat curves in a heat path the whole process is defeated . Same with wood heat . Recover too much heat from your flue and you kill the draft and concentrate solids in the flue pipe (creosote) instead of venting it to the outside atmosphere .
Good point! Escaping heat in the flue maintains the draft and dissipates the creosote. I have seen several chimney fires caused by built up creosote. You should put salt in the fire every so often. This chemically removes creosote. Frank...
