Wood stoves are awesome! They heat the house more adequately than a traditional fireplace...and they burn less wood for the same amount of generated heat. If you are fortunate enough to have one, you may not even need to turn on the home heater at all!
Yes.
The historical fireplace was good for nothing, but decoration. It had to be very cold in the castles!
Now, the wood burning stoves are quite sophisticated, high tech design. They are very efficient!
But the activists will find problem with everything, but windmills and solar cells. Despite those being very inefficient, polluting and destroying environment.
E. G. Solar cell energy causes most death per unit of energy.
Reason - they have to be cleaned and the cleaners occasionally fell down the roof!
The dangers of windmills are very well known too!
