Old wood that is neither painted nor otherwise treated can be picked up from any neighbor with us. Almost everyone has a tiled stove/fireplace. Well, and a wooden house builder simply builds with wood.
Wood stoves are becoming less common. Next year there will be a big death of tiled stoves
The opposite is the case. Or do you have any evidence? The stoves nowadays burn extremely cleanly, and especially with the advent of heat pumps, more and more people are relying on backup wood. It is also CO2 neutral compared to oil and gas, as it is a renewable resource.
