Absolutely. I know I'll have to be stoking and feeding a larger, higher temp fire. But, I'm in what is known as an interior rain forest, similar to the coast of BC, Canada and WA, USA except instead of rain all the time, it snows a ton and the temperatures hover below freezing most of the time. Not very cold here. Mild winters. An unusual zone. A few cold snaps here and there when an Arctic cold front sneaks in, where it goes to around 4F (-20C) but they typically only last a few days. The world is warming in general anyway. I'm happy with my BK and they seem to both overhyped and undervalued for their abilities quite often. There are a lot of variables and some subtle nuances as to their applications.
Im not knocking blazekings, they are great stoves. At those temps if you have a tight, well insulated house you could probably run it like shoulder season all winter. But if an average insulated house, if it's cold enough to snow you will have to crank it up.
