since it is going to be a cold night/day tomorrow, I thaught it would be a good time to do some testing. since all of my other test were done when it was warmer out. picked up some Green Supremes from lowes today to try out. heard good things about them and lets eee if the stove like them. at 3.94 per bag or 177 a ton figure I can go wrong. so far i have noticed a 75 deg increase over the fireside.
