1.4 System structure and operation Ground source heating system Ground source heat pump system ver. 1 Principle drawing of a ground source heating system. 1: brine circuit (horizontal ground loop, borehole or lake/pond system); 2: ground source heat pump; 3: heating circuits (radiator heating or floor heating); 4: domestic hot water heating; 5: passive cooling (optional). - Page 9 increases by a few degrees. The brine is then pumped into a heat exchanger inside the heat pump: the evaporator. In the evaporator, thermal energy is transferred from the brine to low-pressure refrigerant, evaporating the refrigerant. In vertical systems, a deep well is bored into the bedrock. In horizontal systems, an extensive coil of plastic pipe (PEM 40/10) is buried to a depth of 1–1.2 meters or more or submerged in a body of water (minimum depth: 3 meters).
