No, the figures are from the manual and the unit was always like this. Installed new from a quality manufacturer in 2000. Initially we intended to heat the entire house with a heat pump, but one really only gets good efficiency form a water-water pump. In our location this would have meant to drill a hole 150-200m deep. Much too expensive for a single house. We decided to use wood and solar collectors for heating instead. Almost maintenance free since 19 years - no planned obsolescence here.

May I ask which make and model? I'd like to take a look at the data sheet. I'm really curious about this discrepancy between the COP number you mentioned and what other sources are telling me you should be able to get. I'm obviously missing something here.
