Currently I just open the garage door and turn on a box fan. For winter, I am working on a series of fans so i only have to crack the door. Here is a prototype.

Did you have any problems using 1" npt couplings for the elements given they are nps?

No, they seal great. I used some pipe tape and suggest getting a element socket. I applied a good amount of torque to get them to the oring between the box. Not a drip.

Oh make sure you get half couplers, you cannot weave the element through a full coupler, or at least that is what I read

Those look like COMAIR/ROTRON fans. Nice...

You have the exact system that I want to build. I had a question. When you are sparging with the copper manifold in the coolor, do you have any problems with stuck sparges? I didn't know if recirculating with the manifold would be more problematic than using a false bottom.

Through 9 batchs, not problems. I have even done a batch with 75 percent wheat. I did use 1lb of rice hulls for a 10 gallon batch. I had the flow slow a tad when I was recirc'ing once, I could see the hose from the cooler not filled at the output from the cooler. I shut the pump off, stired and it was back to normal.

If you have any questions, let me know. I might actually have 20 ft of sjoow cable left. I thought about expanding to 50 amp though, so I might need it.

I have replaced my pickup tube in the bk with a 1/2 hard copped 90 that goes into a T that I attached a stainless braid to. The braid makes a circle around the bottom, about 1 to 2 ins from the edge. With my whirl from the return and letting sit once I hit 80, I leave a ton of break material.

I also removed the 90s from the input of the pumps and rotated the heads so the input is pointing down. I have not no problems with the pumps cavitating when pumping boiling liquid.
