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

Enthalpy heat exchanger?
Bless you!
No, an enthalpy what? No idea. ^^
We have a Tecalor THZ 504 and one of those Multibreeze units from Pedotherm. Does it include something like that?

I couldn’t find anything in the datasheets so far. Maybe there is something like that available as a retrofit...? However, this should really be answered by one of the controlled ventilation system experts.

It exists, approximately €750 according to Google

Oh, right, moisture recovery. I’ll have to wait and see on that; I’m usually happy when moisture is removed from the house.

You often read that without a heat exchanger, the air can become very dry during the heating season when using controlled residential ventilation. Whether that is true or not, we have simply included one and hopefully will know how it “feels to live” shortly before Christmas. But @kati1337, thank you for your report. It reinforces our feeling that we made a good investment.

11,000 kWh per year amounts to roughly 30 kWh per day. Regardless of the technology installed, including servers, air conditioning, controlled ventilation systems, etc., this is still far too much.

As a single person, I already feel like a heavy user with about 3,000 kWh. But this also includes a home office with two computers and monitors, a large waterbed, and a lot of cooking.

Single yes, that fits
