buy new stove or keep us stove 6039

Here is my question. Does it make sense to keep stove or buy new stove. The reason we were thinking about buying a new stove is because we always seem to play the game of leaving stove on and roasting or coming back to house and freezing. this is a manual light stove. I would imagine we would safe on pellets due to having full thermostatic control and higher efficiency. We do use this as our only heat. The stove does need a new agitator motor and possible control board issues.

I'm for doing what makes you all comfy. Go new!
