The temperature of the ground surrounding the pipes WILL determine its temperature, and it will NOT change even if the water runs for 20 minutes.

Will a commercial chiller change the cold water from 84 degrees to 70 degrees or less even when hot pipe lays on cold pipe in rock trench with circulating pump on a cold water 800ft loop?
