Looks great!

I'm amazed at the % of aluminum you have covering the floor!

The difference in length will cause a difference in fluid resistance, but it is a linear change.

So, if you are different by 2 feet, the change will be 100 x (2/143) = 1.4%

I wonder how it would work out if you poured mortar into the gaps of your curves, to help to thermally connect the loops to the floor?
