Active Solar Thermal
Solar thermal collectors are used to load the ground during summer; then, in winter, the heat stored in the ground is extracted to provide heat to the heat pump evaporator. Currently, used space (room) heating systems involve floor or wall heating, where the heating medium does not (and may not) have excessively high temperature, above 40 °C.
