The first day was the construction of the tank itself with foamboard and spay foam and the beginning of fill, which is mostly sand. The second day included the addition of temperature sensor conduits, as well as the heat exchanger hardware for both the solar heating loop and the house extraction loop. Also the domestic hot water heat exchanger was added.

This week really marks the kick off of the project. Don Roberts, our general contractor, is now on board and will start moving the rest of the renovation forward.
