I see lots of posters here that comment on burning wood efficiently, but for lack of experience, this is such a vague concept. Can anyone experienced in these matters describe how to efficiently burn wood and how you know that you are burning efficiently? And just to make things more complicated, how do you achieve an optimal burn with hard woods vs. soft woods, in a wood stove vs. fireplace? Or have any links that might be helpful? Thanks a bunch. Looking forward to hearing the responses. Going out now to enjoy the beautiful weather.
