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

To get back to the original topic.
We have a residential house with 242 m² (2605 ft²) of heated living space and 32 m² (344 ft²) of unheated area. There are 2 adults and 2 children living here.
For heating, we have an air-to-water heat pump installed and on the roof, a photovoltaic system with 9.92 kWp without battery storage.
This year, we consumed 7,185 kWh from the grid and used 3,008 kWh from the photovoltaic electricity. That makes a total consumption of 10,193 kWh.
We fed 6,741 kWh back into the grid.

@Baufie, how much of that is the heat pump’s consumption, and what insulation standard do you have?

The air-to-water heat pump display shows a consumption of 12,000 kWh...

Well, presumably your air-to-water heat pump is poorly adjusted and consumes more energy than necessary.

In our 4.5-room apartment, we had an electricity consumption of almost 6,000 kWh. So, I don’t really find the additional 4,000 kWh, including heating, to be that much.
In our household, the washing machine, dryer, and dishwasher run almost every day. So, I don’t consider that consumption to be excessive.

Do you consider 10,000 kWh (10,000 kWh) for a house of this size—including heating costs, hot water, and summer cooling via the air-to-water heat pump—too much? I also think that’s too high.
