I Can get a new regency I2400 w/blower "new" for 1800 bucks. BUT i have many questions. My house is a 2006 Mobile home 32x80. It has a factory Intertherm wood burning fireplace. I need to save on my electric bill. peaks 400 in dead of winter. electric furnace. Do you think the chimney i have is sufficient enough for the 2400? It looks to be a double wall 8 inch pipe. I'm going to do the labor my self and need idea's and suggestions. thanks JR
