Are new stoves safer? Do they have less creosote buildup?
Creosote is a combustible residue formed by wood gases that are not completely burned. If too much creosote builds up in a chimney, it can lead to a chimney fire. EPA-certified wood stoves burn more efficiently than older non-certified models, resulting in less creosote buildup in the chimney. So replacing an old, non-certified stove with an EPA-certified stove will reduce the chances of a chimney fire. Nonetheless, EPA and fire officials recommend having your wood stove, chimney, and vents professionally inspected and cleaned each year to keep them in safe working order.
