Not half here, but 60% is a good honest number, based on a (colder than average) year of use.\
I'm working on a pic tutorial of just how difficult it is to run an EPA secondary burn stove. I let it out today, and just restarted it. I'll have pics of each adjustment, with times on em. I'll probably have to do the same with a "hot reload" over coals, as that's how I usually use it from Dec-Mar. It just happened to be warm today, so I let the fire slide. 66.5° in the basement when I came in tonight. 26° outside currently, and dropping.
