Title: Energy recovery

The goal is to both new and existing homes, the excess energy is to use a solar system to support a geothermal heat pump. In the summer we help the soil to regenerate itself, by the heat and save energy in the ground Erdsole. With the release of energy from solar, geothermal brine medium in the solar components are protected from excessive heat in summer, thus extending the life of the solar system. In winter the temperature of the solar system is mostly insufficient to heat the hot water heater, but the temperature difference from the geothermal brine circulation pump is so high that the otherwise unused energy can be used for preheating.
