The “Aspen” adds a modern, flat-top touch to our smaller sized stove line-up.  It’s also amazingly versatile for installation due to its low clearance requirements.

The Wood Classic ranks in the top 10 of all stoves for EPA listed BTU output.  And, when compared only to similar non-catalytic stoves, ranks even higher.  The Wood Classic has more than a decade of proven performance under its belt, and a fair amount of that from cold north Idaho winters.  The Wood Classic boasts a number of “ease of use” features that make it a real workhorse stove, and the optional ash pan is sizeable and handy. The real benefit to our “live” ash pan system is the ability to empty the pan first thing in the morning with coals still in the stove.  Other “plug” type systems need the fire to be out.

Sequoia-Insert-Gold-1200

Manufacturer’s Approved Pricing:       $2,629

Special Pricing Available.

(Special pricing is with standard black door and black steel legs. Upgrades are available)

The Sequoia model boasts the highest tested efficiency of any stove in North America.  With an EPA listed efficiency of 84%, the Sequoia edges out several other large catalytic stoves for the top honors.  The Sequoia is also one of the top BTU producing stoves ever made, with the ability to comfortably heat up to 3,500 square feet.  And lastly, the natural convection of the Sequoia has to be seen to be believed.  The volume of air being moved by the stove’s design, without the help of a blower, is truly remarkable.
