We don't get that cold very often. low to mid teens is more like it..and I'm glad of it. If I didn't have to leave the house i could deal with it better..lol.40 hours ? Damn that's awesome ! ............Am excited to see what this stove can do when we get a cold snap........Doesn't get as cold you but we get into the single digits from time to time.
The wife and I snowmobile also and 0 is just to dang cold or else we might have went out tonight.
