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

How do you do that?The household consumption is average, judging by the other figures I see here.
I think I have the heating system well adjusted, and the house is not oversized for a household of three with 125m² (1,345 sq ft).
I just have to take the time to calculate what portion of the heat pump’s energy goes to water heating and what portion is actually needed to heat the house. Even if the controlled ventilation system could save 20% there, I estimate from experience that it would only amount to about 60–80€ per year. Most of that would then be offset by the electricity costs of running the controlled ventilation system.
There are enough analyses showing that the electricity cost of a mechanical ventilation system with heat recovery is about 60 euros plus approximately 60 euros for filters, totaling around 120 euros, which roughly corresponds to the savings in heating energy. The investment does not pay off financially. But I don't mind, because the ductwork for the mechanical ventilation system lasts the entire lifetime of the house. And a new mechanical ventilation system costs only a fraction of the initial investment during construction.
It is also high time for the government to implement the home office tax allowance, as there are definitely increased electricity costs and other expenses.

How do you do that?So, I just checked the figures from 2019 again. In 2020, we probably used more household electricity due to the pandemic.
2019
Household electricity approx. 2650 kWh
Heating total 2600 kWh
Electricity use in summer for hot water approx. 1.2–1.4 kWh/day
- so heating approx. 2100 kWh
- hot water approx. 500 kWh
I have to admit, I expected hot water consumption to be a bit higher.
As mentioned, this is a household of three with a heat pump, without mechanical ventilation with heat recovery, without a fireplace or solar/photovoltaic system.

You are right. A fireplace is also not economical, but it provides me with great comfort. If you apply this discussion to a car, it gets interesting. Nothing there is really economical, neither the air conditioning nor the automatic transmission. But most people say they don’t want to give those up. It’s the same with a house that has controlled ventilation and heating. Only there, the money runs out.
Regarding electricity consumption: 3500 kWh overall last year and 5000 kWh for the heat pump. A total of 8500 kWh. With an electric car, it will certainly be even more now... You won’t get me with a car...
I bought an old 2002 Mercedes diesel for €1400 (approx. $1500), including 2 years of roadworthiness inspection (TÜV). I do all the maintenance myself, which isn’t much, and I’m trying to get it through the next inspection as well.
Cars are a huge expense where a lot of money is burned.
