btw. last month i sold an old wood stove for central heating, that doesn't have active ventilation, to a guy from a part of Austria where those are outlawed.

The old stove of the poor guy broke, and all the once with ventilation are super large and don't fit into his basement, so by law, he would be required to build an extra heating house shack. So i sold him one i had, which was only nine years old.
He was very happy.
