Just finished building first HH. I saw Mo Heat's HH and decided to try it out. Far more fun than just stacking wood and watching it fall over. Anyway, does anybody know which way the air moves through the HH. Inside out or vice versa. The chimney affect sounds good but the outside of the HH will be heated first in the day time. So wouldn't that mean air would be pulled the top and out the sides? The reason I am asking is I am thinking about shrink wrapping the top three feet and pitching the top of the HH to try to improve draft at night time. Anyone with experience with HH stacks let me know. Thanks
