That’s beautiful! So lucky to find such a nice big one especially for a great deal. Most of them that I’ve seen, including mine are only about half that size. Mines a little bigger but not as large as yours. Mine will fit 10 egg tubs so you should be able to get a bit more in yours.
One thing I did notice, I don’t see a fan. I installed a fan in mine because it was actually a consistent 2 degrees warmer in the top tub compared to the bottom. Mine is heated exactly like yours. Considering yours is even taller, I would think your going to have at least the same problem if not worse. 2 degrees may not seem like much but when it comes to incubating, consistency is very important. Plus depending on where you put your thermostat probe and what you set it to, 2 degrees could probably kill a clutch. I would at least check your consistency from top to bottom. The fan is such a cheap fix it’s worth it even if you notice very little difference, I just used a little 12v computer cooling fan for less than $20 for everything needed to install. You could get the fan itself for less than 5 if you have everything you need to wire it up. They push very little air but use barely any energy and are made to run 24/7 for years and it was all that was needed to put me at an exact 88.0 in all ten tubs. I just have it mounted at the top rear center pointed down to circulate the air and keep it from gathering heat at the top.
