I have a Jotul Nordic 100. Due to size constraints and appearance, I have placed it inside my existing brick fireplace. The front of the glass is flush with the front of the fireplace, stove is recessed far back. My question is would I have a better bang for my heat if the stove is out 6 or 7 inches and utilizing the rear flue exit vs. the top flue as it is currently. What I notice is that the bricks inside the fireplace and around the mantle get very, very warm. I don't know if this is good or bad as the brick can also in theory be acting as a heat source when heated or is it wasted energy. Any opinions on this.
