Good morning everyone,
I wanted to ask what your house’s electricity consumption is at night when everything is quiet and sleeping, so what is running continuously?
We have a newly built house, moved in summer 2019. Our building services include underfloor heating (air-to-water heat pump), controlled mechanical ventilation (runs at full power 3 times a day for 2 hours each, then reduced), a photovoltaic system, and otherwise the usual nighttime appliances (phone charger plugged into USB outlet, e-bikes charging occasionally, 2 TVs on standby, Alexas on standby, etc.).
At night, we have a continuous consumption of about 232W (with ventilation running at reduced power and when the heat pump is not producing). I can see this in the app for the photovoltaic system. From 0:00 to 6:30 a.m. we consume about 2.8 kWh.
How about you?
Best regards

Can you still increase the flow rate in the heating circuit? At 0°C (32°F) outdoor temperature, you should have a smaller temperature difference. Can the heating circuit pump deliver more power?Definitely.I will bring this up in the pink forum. Still waiting for the USB for the data log, because without the data log there’s no point in asking ;-) I will check the consumption tomorrow with the new heating curve and will start the heating in the basement the day after tomorrow, since I found the following:
„...unheated rooms within the thermal building envelope inevitably lead to a higher heating load in the heated rooms ... which logically can only be compensated by higher flow temperatures...“
Thanks for the hint.

Daniel-Sp21 Dec 2020 18:34At 2°C (36°F) ambient temperature, the heat pump still delivers just over 7 kW of output. And that heat needs to be transferred away.
We currently have an average electricity consumption of just under 3 kWh. This applies regardless of whether the energy comes from the grid or from our photovoltaic system. We use only LED lighting, a state-of-the-art pool pump, a large mechanical ventilation system with heat recovery, network equipment, and so on. I’m surprised by how “low” the consumption is. For example, I know of smaller pools that alone consume as much energy as everything combined in our home. Heating is done with gas. I can’t make any predictions on that yet, as we’ve only been living in the house for a little over a month. There has also been a lot of testing (pool heating, etc.). As soon as there is sunshine and the shading on the upper floor is used, the heating will only be needed for hot water.

Or 3 kWh per hour, meaning 3 kW?
The first would indeed be very low.
The second would be extremely high.
