Hi, I have an older Quadrafire 1000 pellet stove with a ceramic firepot. In the bottom of the firepot ( the upper side where the pellets drop in) was a dome shaped part that disintegrated over time. I'm not sure what the function of this dome is, I'm guessing so that not too many pellets fall into the hole where the ignitor is ( I don't know). Even though the dome is gone, the stove seems to be working fine. Anyway I've looked into replacing the fire pot with the new cast iron ones, but they are 500.- (yikes) and I'm trying to find a cheaper alternative. I have in the past used epoxy putty to rebuild all kinds of things and there is a putty called PC Fahrenheit for high heat.It's like play dough and I could easily mold the missing piece. I'm just not sure if the putty would hold up.It's rated up to 500 degrees F. I don't know how hot the firepot gets. Has anybody here tried a repair like that? And if so, what product did you use?
