The owner of this stove is preety satisfied with this design but complained that it das smokeback only when there is lots of fog that you can't see only white outside but than again when that happens it is not that cold and you can use the sistem before and afther to have a good temperature inside. This I am thinking it might be because there is mostly steam coming out than smoke and the fog is also water vapor ...Satamax Antone wrote:Smokeback?
