Load it before bed and there are still glowing coals to catch in the morning. No 3am trip to the stove.
Side panels cut the clearance to combustible materials, so it fits rooms other stoves of this output cannot.
Non catalytic combustion means nothing degrades and nothing needs replacing every few seasons.
A glass airwash system keeps soot off the ceramic glass, so you actually see the fire you paid for.
A 5/16 inch steel top reinforced with a stainless heat shield handles decades of hard heat cycles.
Engineered and built by Drolet near Quebec City, and covered by a limited lifetime warranty.
