    • A furnace insert (10) for an enclosed fireplace is disclosed. Furnace (10) includes an outer housing (11) and an inner housing (50) which define a firebox (11A). A plurality of tubular steel ducts (45-52), inclusive, are mounted within firebox (11A) and heat air as it rises through the ducts from inlets at the bottom and out of outlets at the top. Additional heat is recovered from the furnace and, in addition, an insulating effect is created which prevents damage to the fireplace walls by a heat exchange chamber (54) which is defined by a space between inner housing (11) and outer housing (50) which has an air inlet (54A) at the bottom and an air outlet (54A) at the top.
