Ok, this didn't happen without trials a tribulation, took 3 tries and it not saying that it's the only way to do it.
Try 1 Bought stove and thought that I could out think physics. I moved the fan from the cool bottom and placed it next to the top and put the duct work on the bottom to run it the duct work underground to the building and come up through the floor. Problem fan was sucking hot air because the dog house got hot and it kicked the GFI switch where the fan was plugged in at and then the heat from the stove melted the motor and dang near burned down the whole outfit.
Try 2. Put the fan back down low. made a new top cover with a 8" outlet, then dropped it down to still go through the duct work underground. Problem. If the fan is not running, no heat is coming in and as the stove starts to die out the fan kicks on and off on and off because I have a heat switch hooked up High on the stove and no thermostat in the shop.
Try 3 Put a window in the back wall of the shop, ran a 8" duct work inside a 14" duct to protect it from the weather, then run the underground one to the fan to make it my cold air return. Problem hot air blowing in right on top of the cold air return and it just makes a small circle, no heat in shop.
Try 3.A Moved the cold air run over to the side and down the shop wall, now pulls the air down the shop and down from the ceiling. As the stove starts to die down the warm air just keeps flowing in the shop just not with the force of the fan.
AHH Tractor gets all warmed up while I'm eating breakfast, go plow snow , put the tractor back in and it gets all nice and warm and melted off, ready for the next snow storm to hit.
My shop is only part of my building so I control the temp by opening the door between the shop and storage area . The stove is not shy about eating wood, burn more in half a day than I do all day heating my house, but BLUE is worth it..
