My wife and I live in a 2600 sq. ft. 1931 cape cod style home in Oregon. We are converting our traditional fireplace into a more efficient fireplace insert. It is difficult to keep the house warm (above 65) in the winter without spending a lot on electricity. We are considering the Quadra-Fire Expedition II and Kuma’s Cascade models. Based off of specs, the Kuma appears to be the victor, but it is less aesthetically pleasing. If you have experience with either of these, could you give us your feedback? Advice on our choice would be greatly appreciated. Thank you for your time.
