WHAT DOES GREEN ENERGY WOOD PELLETS FOR HEATING MEAN?

I'm leaning toward a pellet stove for the reason that I now burn off pellets in my basement. Also a woodstove would call for quite a bit of piping and would have to be Positioned near the center of your garage to vent out on the roof earlier mentioned the ridge. I'm scheduling on buying a applied pellet stove with any luck , around 40,000 BTU's.If
