No thanks on the Drolet stoves. The 1500 insert would fit but it has low efficiency, and there is no local dealer.If you are heating with a decent heatpump in our climate then the advantage of a low and slow cat stove is diminished. It makes more sense to run the heatpump in mild weather than to burn low and slow, especially if the firewood is purchased. You could save a lot of money and heat well when it gets cold with a Drolet Escape 1800 there if it fits the fireplace. At that price point the tax credit savings becomes moot.
I agree with you on heat pump usage. Mine will still be the main source of heat, with a wood stove as supplemental heat in colder weather.
