We did a lot of research. The Napoleon Altitude X36 has the best flame pattern and height of any fireplace we have owned. I have been recommending it to all my family and friends who are building homes in the spring.

Bought in 2022 for our newly built house. Initially, our only heat source was the Altitude X36. We couldn't be more glad of our purchase and it looks stunning with the Birch Logs.

Beautiful logs, great amount of heat. The logs and glass media are stunning compared to our old fireplace. Looks better than the real thing. The amount of heat the unit puts out is enough to heat the majority of our house. Very impressed.
