My husband and I bought an old stone farm house just over a year ago. It is roughly 160 yrs old with all of the wonderful character and nooks and crannies. Unfortunately, with old houses, there are lots of updating. Which brings me to my question. Our fireplace (opening) is about 45 inches wide and 35 inches high (29 inches deep). The flew is cracked and ragged all the way up so we will need to put a new liner in there - but the opening is too big to allow for proper ventilation. We've looked at some stoves and liners but these all seem to decrease the size of the opening to practically nothing. It is so beautiful in its grand size - I understand that it isn't practical but are there any other alternatives?
