Air-water heat pump in the building application

Hello,

I am planning to build my house with an air-to-water heat pump. For a neighbor who has no consent to declare for the building application.
Does the pump have to be marked on the site plan already at the time of application?

Yes, of course...

Source?

Well, a source is also difficult to find for the statement, because heat pumps do not require approval or acceptance (regarding building application).
