Planning of the technical room (distance between devices)

We are currently in the shell construction phase, and besides the kitchen, the utility room was really the final boss when it came to planning.
We submitted a very specific 'furnishing proposal' outlining how we could imagine the furniture and distribution of the technology. Our general contractor approved our plan because we left more space for the technology than the required minimum dimensions. We had initially asked the general contractor or their subcontractor for these dimensions and did not receive them, with the comment: not to really plan with these minimum dimensions... So we researched the size of the technology ourselves on the internet and put together the layout of the utility room (electricity, heat pump, storage tank, water including softening, etc.) including our wishes like a sink, dryer, washing machine, laundry drying rack.
Then we sent it back to the general contractor, received feedback 'that looks very good,' and now construction is underway.
I can understand that every craftsman wants as much space as possible for their trade, but as the client, I do not want to 'waste' space. For me, that is passive technology; for example, I need the heat pump every day, but I do not have to actively interact with it. Sorry if that is inconvenient for the installation, but I have no square meters to spare, and the quoted craftsman prices for me include a 'pain allowance' for inconvenient installation.

Danwood standardly plans, I believe, with ERS 10-400, which is for wall mounting - as it also appears in your drawing. You have to be careful, the main connections go upwards and are very thick, so they need space and you will most likely not be able to place anything underneath because the device also has a condensate drain at the bottom.

However, I only meant to shift the two "circles" (brine lines cold/warm) from left next to the heat pump (as currently planned) to the right. Placing the heat pump overall next to the door would, in my opinion, be unfavorable; the brine lines should not necessarily run longer than necessary under your floor slab.

Sure, attached is our plan of the utility room.
For your information: We have another room adjacent to the utility room for storage / freezer, etc.

If you are not yet set, a suggestion... Photovoltaic storage and inverters can easily be stacked on top of each other. Ventilation distributors save space when mounted on the ceiling. I cheekily moved your front door 20cm to the right.
