Of course. However, the heating system does not know why its control variable behaves so strangely, has never heard of EER before ;)
That was the question.
In the first 2.5 years we had 1271 cycles. Today, 3.5 years later, we have 1723 cycles in total. So about 500 units in the last 3.5 years. The heating system only counts cycles of 10. So there are 5000 switching operations.
The difference in the values is enormous. Under 1500 compressor starts per year is really good. The 5000 in the first 2.5 years were clearly too high. Congratulations on the successful measures. It is no surprise that energy consumption has not decreased significantly if the heating demand has not changed much. The system should be running somewhat more efficiently since pressure does not have to be built up as often. Much better now is the forecast of the service life for the device. That everything has become quieter is understandable because every compression process makes noise. In addition: instead of running more often at high speed, the system is likely to run longer now at lower speed. Lower speed —> less noise.
