ᐅ Typical energy consumption based on practical experience?

Hello everyone,

We are new here, and unfortunately, the reason is not a happy one. I would like to continue working on my outdoor area but, to my frustration, I have to deal with this online.

We have been living for a year now in a low-energy prefabricated house. The Vitocal 200 heating system has already had several failures, with customer service disappointing us repeatedly. (We expect more from our apprentices.) But that is a different topic.

From the beginning, I had the impression that the air-source heat pump consumes quite a lot of energy. This was repeatedly denied, and I was referred to the year-end statement from my energy provider. Now I have checked the meter myself and almost fainted: 5500 kWh of electricity consumption just for the heat pump in one year!

Before receiving the usual "relative explanations" from the manufacturer that I’m used to, here is some information about us:

We live in the Southwest Palatinate region (together with Mainau, the warmest area in Germany).
We are both working full-time, only occupying the house in the evenings, and only one person showers.
The set temperature is 20°C (68°F).
The blower door test was passed with very good results.
The house is ventilated by opening windows 3-4 times a day; otherwise, the windows remain closed.

The prefabricated home provider advertises this house with heating costs of €36 per month, which corresponds to approximately 2080 kWh annually based on the EON tariff.
Their calculation is based on 22°C (72°F) in the living room and bathroom, 20°C (68°F) in the kitchen and children’s room, and 18°C (64°F) in the bedroom and other rooms.

We maintain 20°C (68°F) in the living room and bathroom; the heating in the children’s, bedrooms, and adjacent rooms is turned off. Most of the doors on the upper floor remain closed.
We think that with these settings, we are on the energy-saving side, which is why I am so surprised by our energy consumption despite the harsh winter.
As a solution, a service technician suggested lowering the set temperature even further! He was serious about this.

Since the provider does not take our complaints seriously and either does not respond or only replies after weeks, we are now looking for support here.

Who else lives in a comparable prefabricated house? What is your energy consumption? Please post! I need comparative figures to assert myself against my provider.
If you have neighbors living in such a house, please ask them and share their consumption here.

Thank you in advance for your responses.

Good evening,

This is not a prefabricated home provider 😉

... and honestly? I wouldn’t have expected this provider to approach solutions so—let’s say—reservedly...

If you really want to report honestly and objectively, you have the opportunity to do so here on the forum. Send me a private message and I’ll gladly explain how to do it in a way that even beginners can manage 😀

Best regards, Bauexperte

I will do that. Once we are finished, we will also have the lawyer clarify what I am allowed to publish, how, and where. We want to create a website, blog, etc., so others don’t make the same mistakes we did. By the way, they have already been offered to us as a prefab house provider; meanwhile, I’m reading between the lines on various websites...

And how do I send a private message? Right now, I only have access to the internet on my phone, and I’m not really familiar with the site on such a small screen since I’m used to large displays.

Any page you like can be pinned to the top; on the right, you will then find your username and next to it "Conversations." Click on it, and a new page will open where you can enter my username in the "Participants" field under "Start Conversation," and voilà, you can send me a private message 😉

Best regards, Bauexperte
