Playing around with the laser thermometer and took some readings I found interesting. Some that may answer questions for how hot things get. The stove is an NC30 positioned 45 degrees to a perimeter masonary wall. Closest corner is 3 inches from the wall. I have built a heat shield wall to protect an interior wall and another to deflect heat off a wood veneer french door. The stove side of the heat shield wall was 190, and the door side was 125. The wall is 2x3 steel stud with full coverage on the stove side of hardibacker or hardiboard. The door side of that wall is the same material with a 2 inch open space top and bottom to allow cooling via air flow. It seems to work well based on the difference between the sides. The cement floor beneath and around the stove was 127. The masonary block wall rang up at 280 degrees. The stove was in coal burn-down mode after running normally all day.
