Well, my needle is at about 1/3 into the active zone when I reload (1/2 of the total guage, counting both inactive and active zones). It's not too hot, at all, usually. I mean, I can't put my hand on the stove top LOL. It's still radiating heat but not that much, and the corners of the house away from the stove are cooling off at that point, too. Just enough embers to set some more wood in there and let it fire up again. I am using fir splits, mind you, saving some larch for cold snaps, so it burns fairly quickly. We don't have a lot of hardwoods where I live.The definition of "hot reload" can vary, I guess. I usually reload when stove is still active, but nearing inactive threshold. I don't call that a "hot reload". To me, a hot reload is when there's more than just coals in the box, and the needle is still way up into the active. Called "hot" for the way it curls my eyebrows and takes hair off my forearms.
