Ehntr, we have been doing/using the exact same set up for heating, works fantastic. The 20 ponder will throw some serious heat and within a couple minutes, we are able to get dressed, get out to the cook tent, and get a fire going in the stove out there. Cant say enough about having a quick blast of heat ready in the sleep tent, without having to re-stoke up the stove. Its nice to let it go out, and only have one stove going in the mornings. Man......not gonna be getting out with my tents this fall, sure am missing it already

keep a strain on er.
