Air-to-water heat pump consumption at 30 kWh per day

For your information: I lowered the heating curve by 1 degree 72 hours ago. The consumption then dropped to 20kWh per day (only heating; TWE remained the same at 2-3kWh). The operating hours fell from ~17h to ~12h per day. If I now account for the system consuming about 200 watts more than it indicates, approximately 2kWh are added to the 20kWh. I suspect that the 20kWh refers to the pure compressor power input and the 200 watts are used for control etc. The temperature increased on average by roughly 1.5°C during this period.

In short
- Target flow temperature lowered from ~30°C to ~29°C
- Outside temperature on average 1.5°C warmer
- Consumption for heating dropped from 30kWh to 20kWh

das sind top Werte! :)

Thanks! At the beginning of the thread, I wasn't sure if the values were good or bad. I’m relieved that the values are good and very satisfied that they are even TOP values.

If anyone wants more statistics, just say so.

Have you all disabled the hot water circulation? Because it really consumes a lot of electricity.

If a circulation pump is installed, it must run at least once a day; otherwise, there will be a stagnant pipe, a paradise for germs.

We had deactivated the circulation due to the energy loss. I have not yet managed to control the pump via a timer switch or similar because the line is directly connected to the power box. So far, the assumption was that I have to turn the pump on occasionally and not at least once daily. It has now been off for maybe 3 weeks.

It even depends on who you ask, I don't know exactly what the regulation is called, whether it’s DIN or something else, it even states that circulation may not run for more than 8 hours a day... but there’s definitely someone here who knows about that.
