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

You’re right. A fireplace is not economical either, but it provides great comfort. If you compare this discussion to a car, it gets interesting. Nothing in a car is truly economical, neither the air conditioning nor the automatic transmission. But most people say they don’t want to do without those. It’s the same with a house that has controlled ventilation and heating. The only difference is that the money runs out faster.
Regarding electricity consumption: 3500 kWh (3500 kWh) in general last year, plus 5000 kWh (5000 kWh) for the heat pump. A total of 8500 kWh (8500 kWh). With an electric car, it will definitely be even more now... 5000 kWh (5000 kWh) for the heat pump and then also heating with a fireplace, yikes.

I don’t understand you. I keep saying that controlled mechanical ventilation is a luxury, not a must-have, but I keep getting challenged and people try to convince me otherwise. It feels like dealing with Jehovah’s Witnesses. I think people mean well, but that doesn’t necessarily make it right.
It’s similar to telling a 16-year-old at the door, “Kid, did you bring a jacket? It’ll get cold in the evening!”
Controlled mechanical ventilation is usually very difficult to retrofit in most cases. And in everyone’s imagination, half the forum pictures you two years after moving in, standing in front of moldy walls, crying and saying, “Oh no, if only I had installed controlled mechanical ventilation, if only someone had told me beforehand!”
Of course, that’s nonsense. If you’re currently happy with your living situation without controlled mechanical ventilation and by simply ventilating by hand, why should it be any different in the new house?

In most cases, retrofitting a mechanical ventilation system with heat recovery is very difficult. And everyone on this forum can already picture you two years after moving in, standing in front of a moldy wall, crying, saying, “Oh no, if only I had installed mechanical ventilation, if only someone had told me earlier!”
Of course, that’s nonsense. If you’re currently satisfied with your living situation without mechanical ventilation and by just airing the rooms, why should it be any different in your new house? The interior plaster is a lime-gypsum mix, so mold should be less of an issue. It’s not that I don’t understand or consider the arguments, but the louder people shout, the harder it is to follow them.
Let’s see what the new energy regulations will bring. Perhaps I won’t be able to avoid installing mechanical ventilation after all...
