as i mentioned here before,my stove is a heritage. i'm new to the woodstove and been burning wood for the last 3 months.when it was first installed the heat was amazing, but i've been noticing the stove its not producing heat as it once was.it's just not the same comparing when it was first installed. i looked inside of it and noticed the ceramic baffle has 2 big holes and you can see the flames going through it,like a leak. i ordered the piece and i'm having it installed this weekend but my question is,would a broken baffle decline the performance of heat?, at first the stove heat the 2 floors and the past few weeks i had to turn on the heater the person changing the baffle is going to clean the stove too so hopefully that fix the problem.
