ᐅ House electricity consumption – what is your usage?

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

It's quite a lot, even if you do a lot of laundry and cooking—we do too, and we even have two households. But unfortunately, we also come up to 10,000 kWh... however, the area is 250 m² (2,690 ft²) and there is an on/off heat pump.

What exactly is an on/off heat pump?

One that can only operate at 100% and run fully. In contrast, there are also modulating heat pumps that can produce only 2 or 3 kW of heat depending on demand.

Whether on, off, or modulating actually has nothing to do with consumption.

10,000 kWh including general electricity is quite reasonable with children, but not critical either. However, a bit of optimization would certainly be possible.

Whether on, off, or set to modeling mode doesn't actually affect consumption.
What else would it be?

Longer durability of the heat pump (especially the compressor) and, above all, they were developed to reduce noise levels. There are also efficient on-off systems, but it is important to choose the appropriate capacity class for those.
