On a typical winter's day in your area how much wood do you burn in your wood stove/insert? I'm the guy building a masonry heater and I've never owned one. I just saw this ad by a masonry heater builder, "......Masonry heaters are green for several reasons: - They usually operate 70% efficiency or better - normal fireplaces are a paltry 20% efficient. - Better than a hybrid heat source - uses 100% Renewable Resources. - Intense fire reaches up to 1700 degrees - which burns clean and hot (seasoned firewood required) - Masonry Heater owners burn 60-70% less wood than wood stove owners in any given heating season! ............" He is claiming 60-70% less wood than a wood stove. Somewhere he said 40#'s of wood per day in a masonry heater. That would mean a wood stove owner in winter was burning about 100#'s of firewood in 24 hours. I've never run a wood stove or masonry heater as my heating source. Is this claim a stretch of the truth? Do you go through 100#'s of wood in a day in January?
