Once installed in the ground, cables are intrinsically maintenance free. Since their introduction, EHV XLPE cables have had an excellent track record. It is only external influences that could damage the cable, and remote monitoring of the cable circuit allows the rapid location of the fault, so that a targeted intervention can be conducted. Remote monitoring of the cable circuit also means there is no specific need for a permanently staffed route surveillance team.

The heat pump circuit consists of copper tubes filled with Freon. In the low pressure, low temperature section of the circuit, the Freon flows into the wells and retains heat from the ground water (6 °C). It is then compressed by a 5.5 kW screw compressor to high pressure and high temperature. After giving off heat to the house, the Freon is expanded again and flows back into the wells.
