Yep, that is quite common here too (pretty much, Finland is all forest and lakes) but losing popularity. We will have a wood -fired sauna in this place though :) I have a friend I will get the wood from as he owns forest.
btw, I don't know all the proper names for these things in English, only Finnish - it is weird.
A sauna would be good. I remember using one when I stayed in Finland once Christmas. The ones in Britain never seem quite the same.
Wood-fired saunas have a softer heat than the electric, even though they are often hotter.
