KfW 55 standard
Mechanical ventilation with heat recovery
Current outdoor temperature 6°C (43°F)
Heating energy consumption including hot water 35 kWh
Electricity consumption 9 kWh
COP 3.88

Alessandro1 Nov 2021 14:05I reset the operating hours counter (i.e., heating/hot water operating hours and compressor starts) as well as the efficiency values.
That way, I don’t have to note down much 😉

My heat pump has been running continuously since yesterday at 12:00 PM. The heat pump is currently drawing 570 watts. How can I reduce the wattage? I’m asking because 570 watts seems a bit high to me, doesn’t it? How can I tell if the heat pump can modulate down further? The compressor is running at 25 Hz.
This concerns a heat pump.

Deliverer2 Nov 2021 09:55If the heat pump is running continuously, it obviously requires power as well, right? And it couldn’t be better than running at these temperatures. Or is the house too warm?
Regarding the 570 watts, that doesn’t seem unusually high for the heat pump to me. But I have a completely different and much larger one, so I probably can’t assess it perfectly...
Can you check anywhere to read the "compressor capacity in %"?

Alessandro2 Nov 2021 10:06You have a small heat pump with a modulation range of only 1.78kW, from 2°C (3.19kW) down to -7°C (4.97kW).
So 570W fit within the current outdoor temperatures.

Can you read the compressor power in % anywhere? I’m a complete layperson, so I can’t really judge either. The temperature throughout the house is 21 degrees Celsius (70°F), which is comfortable for us. The compressor is running at 25 Hz. I’m not sure if it’s shown anywhere in %. I would have to check again in WP3.

Alessandro2 Nov 2021 10:13How have you set up your domestic hot water heating?
For me, it is 48°C (118°F) with an 8K hysteresis. Hot water circulation runs twice daily to prevent legionella.
I have deactivated the legionella protection because it would mean heating the hot water to 60°C (140°F) once a day.
I am considering setting the hot water to 46°C (115°F) with a 6K hysteresis...
