I see a gain of several degrees on the furnace over the load door and a drop of a few degrees on the pipe. I use a digital BBQ thermometer to measure temps in both places.
with the hopper in this stove there is no "later on" in the burn. to achieve the type of condition you mean i would have to wait 36 or more hrs. for the hopper to be exhuasted or try it some time when i pull the hopper and fire it as a batch heater.
i can gain temp. at constant settings by closing down secondary anytime the stove is burning. that practice drops the effective area of the stove, increases the internal neg. pressure ( more draft on the mano. remember, more draft less secondary, it works in reverse too, less secondary more draft )and so, draws thru the fire bed more, thus, fire hotter over all and more heat.
