Depends in the size of a tree. Near 2 foot in diameter and 60 foot tall red oak will give you a cord of the best firewood there is. 6 inch white pin or post oak, a few nights worth of wood.
One thing they’re probably not thinking of but will figure out is house design. We heat with nothing but wood but we have a small place with an open design. If you have bedrooms that are down the hall and maybe around a corner, the heat from that centrally located wood stove won’t reach the bedroom at all. For modern houses designed for more privacy and with central HVAC in mind and ducts going to each room, you really need a wood furnace that connects to that duct work. They sit outdoors or sometimes in a basement or garage. I don’t think they make a pellet wood furnace and Germany doesn’t have enough trees.
People are going to have to bunk up in the living room where the stove is. Then of course with the whole house not being heated, here come the frozen pipes. Germany is in for an education this winter.

Right! I forgot about those things, I have a friend in Maine who has one of them. But it’s really a pain in the neck, you have to go outside and load in the wood, and of course you have to make sure the fire does not go out.
And, wood stoves are considered carbon dirty, right? Another friend could not get licensed as a day care because they had a wood stove, and it was NOT their main heat, just sort of quaint and decorative. But it was functional and that was enough to disqualify her home. That was in Connecticut.
