Sounds Nice! Sounds Better, but Remember the only item you have that is multi-use is coal. I would recommend a currency made out of paper that you can burn or use to buy. The campfire gives you X amount of cash and changes X by a number. And if it turns off you have 20 seconds to revive the fire with a lighter which you can purchase from the shop with the currency. I KNOW I am complicated and sometimes dumb, but this feels right.
