ᐅ Heating System for New Construction – Which Is the Best Option?

Off Topic:

If you move the door to the shower room, you can gain valuable storage space under the stairs! [emoji2]
For example, for a wardrobe – which I don’t see in your plan, despite the spacious hallway.

As I said, we have a statement from an employee of the district office.

From our experience, I can only give you this advice:

Get it in WRITING! Nobody wanted to remember verbal promises when it suddenly became important for us...

Or just ignore the building authority, build whatever you want, and hope that no one complains during the construction phase. Once you are underway, they can’t make a big fuss over small details.

Best regards,

Good advice, I think I will do that again. However, I have a witness who can confirm the statement—our neighbor, so no one who could be accused of bias.

But it’s true, what you have in writing is definitely secure.

Don’t let anyone tell you otherwise! Of course, you can change the heating system even after submitting the building permit / planning permission, without filing a new application. We did the same, and it was well after the original application. It was absolutely no problem! The building volume must not change, but heating, windows, moving or adding interior walls—none of that was an issue!

I accidentally uploaded the first draft yesterday. Here are the latest plans.

Back to the topic: I only know air-to-water heat pumps as noisy and not heating properly in winter. I should mention my experience is about ten years old. I suspect the system was either set up incorrectly or undersized.
Is there a rough guideline for electricity consumption? How does it perform with hot water when one person takes a bath and another showers? With two women in the household, that’s not unlikely. Currently, we use 4,500 kWh, due to an instantaneous water heater and an under-sink unit.

I am aware that all heating systems have pros and cons, especially if they are not properly configured. However, I think that with photovoltaic panels, a certain level of self-sufficiency could be achieved with an air heat pump, right?

When does your photovoltaic system supply electricity, and when do you need it for heating?
There won’t be any self-sufficiency in that case.
