Well, I posted last fall after setting up my unit. We are still in the heating season, but after the past few weeks hitting actual temps of 22 to 25 below zero. Not to mention wind chill putting it at just freekin COLD. I feel comfortable giving my opinion on this stove. The stove has met or exceeded all my expectations. I could not be happier. My biggest concern when purchasing this stove was with the natural draft as opposed to the air induced draft I had with my previous stove(different brand). I was concerned that the makeup time would not be able to keep up with my hot water and heating demand. I am no longer concerned. The stove has kept up perfectly. My thermostat has not left 74 degrees yet. and my hot water outlasts my entire family. Thanks Tim. Love the stove!!
