Upon completion of assembly, we spent several days troubleshooting and testing our system. During this process, we recorded the rate at which heat was transferred from the reservoir tank to the main tank. Below is a graph of the temperatures of each tank as the warm water from the reservoir tank was swapped with the cool water from the main tank.
 
 

    Pump B is set up to dump cold or main tank water directly into the reservoir; and the reservoir return pipe subtly returns the warmed water to the main tank finishing the exchange cycle. The graph shows a wonderful representation of this cycle and it’s merging effect of temperature. The reservoir shows a drastic change, while the main tank shows a slow change. This is due to the volume difference between the two. The reservoir is only 40 gallons compare to the main tank, which is 350 gallons. This is why the team is very pleased with the results of this test. The team looks forward to others performing this test in the future and comparing results.
