Efficiency does matter.
If you use less wood to heat your house because you burn it completely and keep the heat in your house instead of going out the chimney,
then you will produce less CO2, not that plant food is a pollutant, mind you.
Someone above said he installed one of these “approved” stoves and used half the wood that he did before.
But then you would be agreeing with the EPAAAAAA!!!!!EWWWWWWWW!!!!
That tree has a certain amount of CO2. It releases slow or it releases fast. Nonetheless, you can’t exceed the value that’s in it when it dies.
The approved stove doesn’t change that equation, and the approved stove actually isn’t as usable. It requires a standard water content that can be achieved only with thoroughly dried and seasoned wood. That standard of wood is an unnecessary burden on those who burn wood. Thoroughly dried wood burns hotter and with less smoke, but the time (or money) required to have it is counter-productive for those who work for a living.
This is the real point the libtards miss. We cannot live without CO2. No CO2, no plants. No plants, no oxygen. No oxygen, no people.
