Where I live, we've seen temperatures dip to -40 and when accompanied with a brisk breeze, windchill temps can reach -60+. We have two RSF Opal 2000 fireplace inserts. One upstairs and one in the basement. The one on the main floor will heat our 1800 square foot home even during the coldest winter nights. These inserts are serious heaters and very appealing to the eye. Not sure if they're still available. We've had ours for twenty years and they've been great. They're very efficient and throw plenty of heat. Here's a link. Our model is the second pic.
