Heating and cooling with solar energy. All year long.

thanks for the video, while the principals are sound I find on the system I maintain here in a colder climate that the geothermal mass is far to unreliable for the principals to hold all year. The thermal mass is always lost too early in the season and therefore the energy costs are just about the same as a well maintained high efficient traditional system. Although the hybrid systems that utilize the solar heat are very efficient for water heating.
