So Matt, you have discovered the miracle of Masonry heat!
Isn't it just awesome!
Careful, you do not run yourself out of the house by adding that extra load.
Midwinter is easiest: one fire in the morning and one fire in the evening.
Now that spring temps are here, I find one fire is not enough, but two full loads will have all the windows open.
Now I am burning two half loads; we still have windows open, but just for the cool, fresh air.
Just enough to keep my heat reservoir filled but not overflowing.
Shorty is just a wonderful addition to the awesome first-generation Batchboxes.
Thanks should go to Lasse Holmes from Homer, Alaska, for the original Batchbox design, and of course, Peter Berg for all his work in refining, testing, building, and freely sharing his results with the world!
