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

And how do you explain the COP value? Why can only modulators achieve that?

Even with modulating heat pumps, the appropriate capacity class should be selected...

Interesting thread, I already felt bad about our 200W base load :P

Since early October, we have consumed about 780 kWh. It has been exactly 78 days since the SMA Home Manager was installed, so roughly 10 kWh per day (2 adults and 2 small children).
Of this, 213 kWh was self-consumption, plus 207 kWh from the battery storage, and the rest was purchased.

The photovoltaic system generated a total of 9,837 kWh over the year (10 kWp, southwest orientation with a flat roof at 8°).

What exactly are the mysterious 10,000 kWh read from the heat pump? Is it really the electricity consumption, or is it the thermal energy generated by the heat pump? The former seems quite high to me, while the latter does not.

I think he definitely has a 5k household. That leaves 5k for the pump. Fits well.

Are you referring to me?
