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

That's easily 500 euros deducted from the electricity bill per month? 🙂

3kW per hour. That’s low for the house and equipment.

Ok, so 3kWh (kilowatt-hours) per hour?!

Considering that you’re heating with gas, that’s an incredible amount!
10 times more than a typical single-family home.

Is that really a discount of 500 euros on electricity per month? 🙂
If you can, you can 😎

...and I’m optimizing my heat pump so it uses 5 kWh less per day. Oh man :-D

It is also somewhat larger. In addition, the pool currently circulates water 24 hours a day. A mechanical ventilation system for indoor air that is sized 10 times larger. Over 30 cameras, a large network with servers, perimeter security, and so on.
The network alone with its peripherals consumes about 1 kW.

Well, I’m a bit saddened by how some people handle energy.
But okay, it’s probably just the tip of the iceberg.
All the concrete that went into the project probably makes the electricity consumption look insignificant by comparison.

Hopefully at least a large solar panel system.

Yes, photovoltaic systems are included as well. In summer, the waste heat from cooling is used to warm the pool.
No sealed surfaces, green roofs, and so on.
I once looked at the utility bills from our previous apartment. There, both electricity and heating demand per m2 (older multi-family building) were significantly higher.
The Renewable Energy Act surcharge supports renewable energies. Just look at what happens when electricity demand suddenly drops.
If you talk about using resources in construction, then no single-family homes should be built at all. Nor garages, carports, terraces...
Let’s not even start on holiday flights, pets, meat consumption, or children.

When is your house construction starting? How big will it be? What percentage of the plot will be built upon? Possibly wasting space? Would another single-family house even fit there?
See what I mean? You’re sitting in a glass house as well.
Our building can be used even after we pass away. We have no children (didn’t work out, and the desire wasn’t very strong either).
You plan to have two children. That obviously increases resource consumption considerably.

So feel free to say the electricity consumption is high. You don’t know the details of the house and can’t realistically assess whether it is actually efficient.
If that makes you sad, you should rather look in the mirror and ask yourself if you live accordingly.
