Newly built single-family house - gas or air heat pump + photovoltaics + storage?

Exactly my opinion. So, back to the text.

Edit: No, wait. I should stay factual.
So: do you have any scientist who supports your position "Gas is still kind of okay"?

Thanks to everyone for the comments so far! It is a hot topic, I know.

We will talk to the two neighbors to find out whether they would (potentially) be disturbed by an air-to-water heat pump or not.

The general contractor (or the commissioned heating engineer) only installs Vaillant. We are also getting the controlled residential ventilation from Vaillant. We have no key data yet like heating load calculation, etc., we would need to inquire or commission that.

If you ask the question, the train has already left ;)

Yep. The new parts are quiet. And above all, they comply with current noise emission limits. You might want to make sure you don't get sold a model that came out 10 years ago. About three or four years since market launch, modulating, and preferably (but there aren't many) with R290. And of course, it always helps if you don't direct the noise exhaust straight at the neighbor's bedroom. Rotating it by 90° already helps a lot.

Thank you! It will be a Vaillant Arotherm Plus. We would position the air-to-water heat pump so that it does not point directly at the neighbor’s house. In a straight line, it would be 8m from the air-to-water heat pump to the neighbor’s children’s room and 20m each to the other two neighbors, who are then in direct line of sight to the air-to-water heat pump, but I hope that is not a problem.

So, the groundbreaking has not taken place yet? Stop: I just read that construction is already underway… Then the data should already be available…
