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

To my knowledge, a CO2 price is now being introduced for the first time. But instead of starting at 10€ (about 11 USD), it will begin directly at 25€ (about 27 USD), contrary to the original decision of the federal government coalition. This has actually been settled since 2019.
For a house with gas heating, that means an increase of 0.6 cents per kWh. Depending on the current energy price, this results in 10-15% higher costs. And this is just the beginning. In 5 years, no one will install gas heating in new buildings if this trend continues.
To get ahead of that: this cannot be prevented even with “breathable” building materials.
Although I personally prefer a central system, which is within the mentioned price range, it doesn’t necessarily have to be the “top tier.” Much cheaper options are window frame ventilators and a few exhaust units. That would be the absolute minimum requirement for me. Above that, there are decentralized units with heat recovery. You perfectly repeated what I wrote in one sentence. It was decided by the Bundestag to start at 10€ (about 11 USD), but this was changed yesterday. The law already existed but was not yet in effect.
From 2025, you will face additional costs of around 200-250€ (about 215-270 USD) for an average single-family home, assuming no further increases.

There is something on that topic: a mechanical ventilation with heat recovery is said to work best without additional earth tubes or air wells.
There is an Austrian forum, and in the red forum, Leitwolf is active who has studied this topic extensively. I don’t want to search too much. However, unless there are absolute counterarguments that would make mechanical ventilation with heat recovery extremely uneconomical or pointless, I will stick to my statement.
By the way, I want mechanical ventilation with heat recovery, even in older buildings. Because when your windows are airtight, you need to ventilate—and frequently at that.
Our annual energy consumption is about 11,000 kWh. The household includes 4 people, with a controlled ventilation system running 24/7, a split air conditioning system also operating 24/7 during summer, home automation plus energy recovery ventilation, a server cabinet (including one data server [24/7], telephone system, router and modems, etc.), garden pumps, garden lighting, and much more.
Is this consumption very high? Yes... but I don’t mind; we allow ourselves this luxury (instead, we don’t spend on smoking or drinking).

Is the consumption very high? Yes... but I don’t mind, I allow myself/us that (we don’t smoke or drink for that). You should consider installing a photovoltaic system. It’s definitely worth it.
