This is a photo of the pump and the pump mount in front of the HVAC unit. The HVAC's side panel has been removed because we needed to access some of the inner elements.

This photo shows the completed piping network between the HVAC and the reservoir. The red PEX pipe goes to and from the solar tank, the white PEX pipe contains ground loop water and the copper piping is part of the heat exchanger inside the reservoir.

The reservoir is located next to the HVAC and is filled with ethylene glycol. This photo shows what the intricate network of the Integrated Loop actually looks like. Also in this photo are the switching valves of the Integrated Loop that need to be changed depending on what cycle the HVAC is currently running.

This is the solar water heater tank. As you can see, it is insulated very well and the Integrated Loop connects to the two pipes on the top left.

Here the mount for the reservoir can be seen as well as the black pipes that go into the ground for the HVAC's ground loop. This is a pretty accurate depiction of how tight the space is underneath the OGZEB.

The four ports shown here are located on the HVAC. The bottom two ports are for the ground loop inlet and outlet. The top two ports are the connections for the desuperheater.

This is a close-up of the connection between the pump and the flow meter. The brown pump can be seen on the left and the silver flow meter is to the right. The blue wire connected to the flow meter is how the computer gets the flow rate measurement.

Here is a photo of the copper heat exchanger before we placed it inside the green reservoir. We needed this heat exchanger to exchange heat with the ground loop before entering the HVAC when running the heating cycle.

This is a screenshot of the labview program. This is what the user will see. There are pictures in the program to make it easier for the user to understand where the different measurements come from.
