The lower oxygen levels that exist at higher elevations will slow down the rate of burn for a wood stove. Because of this, you should select a stove that has a good range of combustion air. The Kuma Aspen LE-1, Tamarack LE-1, Aberdeen LE-1 and Alpine LE-1 all have robust high burns that will work well in higher elevations.
Temperatures are also generally colder in higher elevations. Consider a stove that is rated for heating more square footage than the size of your home. For example, if your home is 1,200 sq. ft. in size, the Kuma Aspen LE-1 would be a great fit as it is rated to heat up to 1800 sq. ft.
Good quality wood and regular maintenance are especially important at higher elevations. It's important to use well-seasoned wood with a low moisture content to promote cleaner and more efficient burning. Because of the thin air, you are more likely to experience incomplete combustion. Ensure that the stove and chimney are installed according to manufacturer recommendations, and conduct regular cleaning and inspections to address any build-up of creosote.
