Much of the temperature gradient from the fire to the chimney top has been lost in the mixing of flue gases and ambient air in the cooking area. In the absence of a fan what would determine what path the gases chose to take, if the hood presented an obstruction the gases would simply go round and up? In a windy area something like the cowl used in oast houses might produce enough depression but that also adds to cost and complication<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, 28 Jan 2021 at 11:17, Ronal Larson <<a href="mailto:rongretlarson@comcast.net">rongretlarson@comcast.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;"><div style="margin:0px;font-stretch:normal;font-size:11px;line-height:normal;font-family:"Helvetica Neue"">Stove list:</div><div style="margin:0px;font-stretch:normal;font-size:11px;line-height:normal;font-family:"Helvetica Neue";min-height:12px"><br></div><div style="margin:0px;font-stretch:normal;font-size:11px;line-height:normal;font-family:"Helvetica Neue""><span style="white-space:pre-wrap"> </span>I’ve been talking with several list members about one drawback of TLUDs being the complexity and cost of adding a chimney.
