Ii thought more on your concern with pump strength and decided to use less line to lighting the work load, instead of 70ft of poly I am going to use 20 ft. of 1/4" primmer covered copper tubing.
The chiller will be raised up to the tanks water level to use the siphoning effect instead of pushing all the water , the pump will use its vacuum to raise the water 10 inches to start the siphon off.

Turns out the refrigerant coil was soldered together in a few places , which is why I could not unravel it.
I cut the stainless chiller bucket apart and was then able to pull the coil free and remove the bucket.
I am going to add a $14 eBay panel mount kWh / watt meter so I can keep tabs on its economy.
That's about it , I will start a separate thread with photos of its construction and test data.
