Wife and i cant say enough about this stove and coal in general! Idles easiliy for 24hrs without touching while keeping the house toasty, and when it was really cold, -18 the other night, woke up to a house temp of 74, and that wasnt even runnng it that hard! Wood stove and cold temps like that=wake up 56 deg!! Much happier now!! I dont miss setting the alarm to wake up at 2am to feed the stove wood and still wake up freezin!! Very happy campers!!
