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

The general contractor builds only houses with Poroton bricks and without mechanical ventilation systems. He is not familiar with mold issues, and neither are we.

Possibly because he doesn’t know how and doesn’t want to argue afterward about why it is noisy and doesn’t deliver the expected effect.

I am not disputing your post, and you can calculate all of this with the U-value calculator. However, vapor diffusion does not mean the walls are "breathable." You still need air circulation.

So, what are your current electricity consumptions? Please feel free to break them down separately for ventilation systems with controlled residential ventilation. This way, we might be able to skip the debate and everyone can compare with or without controlled residential ventilation.

I don’t deny that.
Mechanical ventilation systems do bring in fresh air,
but the absence of mechanical ventilation does not automatically cause mold problems,
even though some here praise it as the only solution.
We sleep with the window open all year round and are woken up by birdsong.

Same here. Just open the window, and that's fine.
