38 Maintenance/cleaning
Although heat pumps are considered low-maintenance heating systems, regular periodic maintenance work offers
advantages.
• Operational reliability is maintained.
• A consistently high seasonal performance factor is achieved.
• Low fault rate.
• The service life of system components can be prolonged.
• Possible damage or faults are detected early.
• Heating convenience is assured in the long term.
• Legal requirements are met.
