The article discusses how to install a geothermal water-to-water heat pump system. During heating, the water temperature in the middle of the buffer tank is monitored by a standard outdoor reset controller, which operates the heat pump. It is stated that one should make sure that all piping that carry chilled water are insulated and vapor-sealed. Also, both temperature sensors should make good contact with the internal side of the thermal well in the buffer tank.
