Here's the original video, and a comment that was interesting, talking about the angle of the black coiled water pipes, and shows insulation and more:

" You said "I would have just laid the coils flat". That was your only comment before mine. If the coils were laid flat then you would in theory ONLY have approximately 2.5M of rise in the diagram at 5:15, if the coils are cone shaped as in the diagram you will have rise(and water flow) in the entire length of the pipe(33M?) plus the 2.5M of rise which will steadily flow water by itself on a sunny day if you could see into the tank. It's a great design A+"
I think the rise must be important. CT
