Opinions please! We have the opportunity to replace our 19 year old stove. I currently have a jotul CB 3 sitting on a 30 inch high raised hearth in front of a zero clearance fireplace. The stove is in an 18 x 18 ft room with a 14 ft high ceiling. Because my hearth is just 17 inches deep, this really put restrictions on stove size plus, I had to deal with issues on flue height to tie into the ZC fireplace. So back in 1996, a CB 3 with the short leg option was my only answer. Now, I would like to install a Flush Wood Hybrid- Fyre insert. I go through about 4 cords and 1200 gallons of oil. (4000 sq ft colonial). We spend all of our evening time in this stove room, so appearance is a must. After 30 years of fire viewing, wood- fire boilers, ( not an option). I know that I will have to install a larger ZC firebox and replace the chimney. So my concerns with this insert are; will I get more heat from my 4 chords?, I never had an appliance without an ash pan. Because I usually burn 24/7, how often will I need to attempt to scoop out ash, and how much dust will this generate in the room? None of my friends have inserts, so I am forced to believe whatever the sale rep tells me. ( a frightening thought) !
