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

So, about 15 kWh/day to 20 kWh/day is used for heating?
If yes, is any of that reduced by the photovoltaic system, or does that entire amount have to be paid for?Yeah, the heating uses roughly 12-18 kWh per day. Our household consumption never drops below 10 kWh per day. In theory, the photovoltaic system should offset some of that, but in the last 3 days it produced:
574 Wh, 553 Wh, 175 Wh.
So practically nothing. 😉
When we get more sunshine hours again, a few kWh per day will be reduced. But at the moment, we are almost fully drawing from the grid.

Yeah, about 12-18 kWh per day is probably the heating. Actually, almost never less. Then that's at least 100€/month for the air-to-water heat pump? 😱

Oh, did you get your driver's license back? Nice... and funny at the same time 😎

In the past few days, we consistently used around 20 kWh (kilowatt-hours) of energy, including heating and household consumption. Photovoltaic performance in December has been quite poor so far, but the overall year was not bad. We generated 10,525 kWh (kilowatt-hours) and achieved 69% self-sufficiency. If the inverter had not been out of service for 10 days in June (usually the best month for photovoltaics), the results would have been even better.

Sun? I honestly can’t remember the last time I saw any. Solar panels probably wouldn’t be worth it for us 🙁Because you need those 12-18 kWh every day of the year.Schimi1791 schrieb:

Sun? I can’t even remember the last time I saw it. Solar panels probably wouldn’t pay off for us 🙁 Well... it is winter after all. Previously, we had a gas advance payment of about €100 for the whole house.
The air-to-water heat pump certainly won’t need 15 kWh anymore in spring. 😉 We moved in during October, and from November to December the consumption already increased a bit. I expect it to rise a bit more in January/February and then go down again starting in March. In summer, it should only be the ventilation system using electricity.
It’s the same with gas—you also pay advance payments in summer for the winter.
My “currently 30 kWh/day” referred exclusively to December. 😀 Just so nobody gets the wrong idea.
Oh, and the same with solar panels. It’s winter. Even in October, we had several days with 10 kWh or more in yield. Right now there’s just no sun, so nothing comes from the roof. 🙂
