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 is unfortunate, however, that there is no chimney – at least it isn’t necessary if the house has a heat pump. This certainly saves additional costs but also prevents the option of connecting a wood stove, which I wouldn’t want to miss anymore.

I would have liked a wood stove for the cozy atmosphere as well. I enjoy reading decoration magazines, especially around Christmas, imagining decorating around a real fireplace… ah!
But we decided against it. With today’s insulation standards, I was concerned that a wood stove would make the living area uncomfortably warm without control. I already notice this sometimes when I light a few candles.
My sister heats her (by the standards of that time) nearly passive house with a wood stove. That might be nice if it’s just two people. But every year we’re invited there for Christmas dinner, and as soon as 8 people sit around the table, it gets unbearably hot in that house; it’s hardly tolerable.

Yes, the heat output of a wood-burning stove should not be underestimated 🙂 Can a mechanical ventilation system with heat recovery also cool the rooms? That might somewhat contradict the purpose of the stove, but at least the cozy atmosphere remains preserved 🙂

I would have definitely liked to have a wood-burning stove for the sake of comfort as well.

It would fit well in your home too!

This is the Kostal app, right? Did they seriously rename the "Live Data" tab to "Recent Data" because they can't get a real live view to work? 😀
The app no longer lags by 8 hours like it did 4 months ago, but now only by 30-45 minutes. So that’s definitely an improvement 😎. Basically, when I’m at home, I always access the network and check the data through the inverter interface.

I really appreciate the live view from SMA.

From a photovoltaic perspective, December was practically non-existent so far; I can produce 35 kWh in 16 days on a sunny May morning...

In terms of photovoltaics, December has been almost nonexistent so far. I can generate 35 kWh in 16 days in December, which I usually achieve by late morning on a sunny day in May...

Could you show me the full day from yesterday? I'm interested in the compressor impulses. Thank you.

Yes, December is really bad. We are only at about 40 kWh for December as well.

Yeah, on the somewhat nice days I had 10-15cm (4-6 inches) of snow on the panels...

You can’t see the compressors here, but there was no impulse yesterday. The heating ran continuously until yesterday noon for about two weeks and then switched off for the first time at 7 degrees Celsius (45°F) outside temperature.
