Just installed this in my shop, Super happy with the unit. Very well built, puts out a lot of heat, I fill it up at night and there are still a ton of hot coals in there in the morning, just need spread out the coals and toss more logs in. The unit seems very well built and well shielded, The top gets super hot as does the vent but the middle of the sides and back are not bad at all. For this uninsulated building, I do need to pre heat a little with the torpedo to bring it up quickly but the stove will hold the temp. It is a good sized building. Very happy with the purchase, this is NOT cheap stuff from China, it is a good quality product. Highly recommend if you have access to wood.
