Heat pumps need to be serviced

Maintenance of heat pumps

Heat pump controls guarantee efficient operation

A regular check of the system is also recommended after this initial operating phase. Manufacturers offer various maintenance packages for this. Your service engineering teams check the system and its functionality. The main focus is on the refrigerant circuit; The compressor, evaporator and the throttle valve have wearing parts, in particular seals and filters. There is an obligation to report for systems with more than 3 kg of refrigerant. A maintenance booklet must be kept, leak tests are mandatory.

Regular testing is also recommended because of the control. As is well known, software is constantly being developed. If efficiency and comfort are to be guaranteed in the long term, updates and updates are therefore advisable. The control of the heat pump also goes hand in hand with the control of the actual heating system with its temperature specifications. In addition, account is taken of the fact that heat pumps and the way they work are in constant exchange with the environment. This exchange must not be disturbed. In heat pump systems that use the air temperature, for example, it must be ensured that the supply ducts are not clogged with leaves or dust. It can happen that sucked in material blocks condensation drains and a potential hazard arises from water damage.

Heat pump system components have a certain service life

Even with good maintenance, heat pumps do not have an eternal life. Manufacturers currently recommend replacing devices after 18 years of operation - also against the background that the technology of the systems is continuously optimized and uses less electricity. This service life relates exclusively to the operation of the refrigerant circuit. Other components of the heating system work much longer. A service life of around 50 years is currently expected for geothermal probes.
