Bought this stove new in November of 2016 after years of research and muddling with customer units trying to decide what was best. I'm heating either 4400 or 5200 sq ft plus domestic water, can usually go 12+ hours on 1/4 load of oak down to 10 degrees, but even -40 takes about 1/3 firebox full for 12 hours. Super efficient for a conventional stove; easy to operate and clean. I love the stove but some unforeseen circumstances have led me on another path and it is now for sale. Has been under a roof since day one and water has been treated and tested by Heatmaster, still connected and full of treated water at my house. Delivery and install is available within MN or western WI. Asking $7500 and located in Central MN. Thanks
