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

Or a generic one for a fraction of that price.

Nope.

plus cleaning of the duct system every 5-10 years
Why? What’s the point of the filters then? How often do you clean your water pipes? Or does something diffuse in there?

It’s like with my 8-year-old daughter. When I say, "You didn’t do this and that," she replies, "But you didn’t do this and that."

Alright, I’ll step back here. Some people prefer to ventilate manually, while others let it be done automatically. Fortunately, everyone can decide for themselves what they want to do.

Exactly. For basically legitimate decisions, no one has to come up with ridiculous alternative facts or first-rate pub talk.

Oops, if anyone needs a maintenance contract for the mechanical ventilation with heat recovery, you can get a volume discount on MyHammer. However, they are hopelessly overwhelmed even with simple tasks like replacing light bulbs.

I haven’t even checked what the mechanical ventilation system actually needs. At the moment, the heat recovery is sufficient for heating, and the compressor has only run for about 1 hour over the past few days to heat water.

I completely agree and gladly pass the ball back.

Back to the topic...

Controlled residential ventilation permanently set to automatic, large French-door refrigerator (currently running at 7°C (45°F)), boiling water tap, hot water supplied by an air-to-water heat pump, 6 Alexas, 1 TV, no server or similar equipment. Heating is currently off.
So you can imagine what is running at night or not. We are somewhere around 280 watts, and then the hot water system turns on once during the night.

The last peak yesterday around 6–7 pm was the iron

Hourly profile of household consumption (0–24 h) with grid feed-in, grid consumption, battery charging/discharging.
