Had a few extra minutes today after lunch so I decided to stop into a stove shop. The sales person started telling me how his stoves burned very clean. Then he mentioned all the stoves at Home Depot and Menards are like "old air tights" and they burn dirty thats why they are cheap. Then he started saying many manufacturers will soon be going back to catalytic style stoves. That was when I had enough BS and I quietly left. Why would a sales person do this? Makes no sense.
