Yeah, I kinda pooched it there. Definitely need to get back to it and add more pipe above the valves, I just blow them out more often for the time being. But the temperature drop across the tubes is surprising.
Your setup looks great, Its almost identical,
If you can go from your pump to your coil you built, then to your tank you will improve alot.
Add more pipe as you say because you will catch ALOT more water.
