We are looking at buying a wood stove, but not sure which kind to buy....ie: catalytic, non-catalytic or go with old style ? I would like to hear from people that have a epa approved stove, as I hear and read they are so much more efficient. We have an all electric house and are looking for supplemental heat and emergency heat. The brand I'm looking at is a Harman, either the oakwood or the tl300. Thanks!
