ᐅ Is it better to install the heat pump inside the house or outdoors?

Hello everyone,
we are currently considering the advantages and disadvantages of installing the heat pump either in the basement or outside in the garden.
Our architect has simply planned to place the heat pump behind a retaining wall in the garden.
- What are your experiences?
- What are the approximate cost differences?
- Would you recommend installing it indoors or outdoors?
The lot is 450 m² (5400 sq ft), with the house including a double garage occupying about 140 m² (1500 sq ft). There would be enough space in the basement.
Thanks

Heating systems must be located within the building’s thermal envelope. Our air-to-water heat pump is installed in a utility room behind the garage. This room is only equipped with a small radiator and was constructed with 24cm (9.5 inches) Ytong blocks (lambda 0.12), just like the garage. During the coldest period of winter, the temperature inside was only around 10°C (50°F). Would this not be sufficient?

Could you please explain that a bit? I don’t understand the reason. Sebastian has already explained it; the utility room (HAR) must be inside the thermal envelope. So if a basement is planned only for storage or utility purposes but the heat generator is to be installed there, the utility room needs to be insulated.
Common sense suggests that insulating just the exterior wall of the utility room with the usual 4 cm (1.5 inches) should be sufficient; unfortunately, the designers of energy-saving regulations and related standards require insulation of the entire utility room.

Your technical room may be adequate for your needs, but it is not insulated as required. However, as always: no claimant, no judge. What does your energy consultant say about this location?

Thank you for your feedback.
Maybe as a note: I built last year according to the old energy saving regulations. Was the rule the same back then?
If that was the rule, I will check with my general contractor. It is already too late, but it definitely should be clarified.
Who do you mean by energy consultant? The one who calculated the heating load, energy certificate, and documents for the KfW? – Nothing.
Neither the general contractor, architect, nor heating engineer mentioned anything. This is common practice with this general contractor and almost always done this way. <= Which doesn’t mean it is correct. I am aware of that.

It was also prohibited, but as the construction expert said, no one complained...

Disadvantages: Longer pipe runs, more energy required to maintain the heat
My colleague has very low electricity costs with his pump, so it can't be that bad. Of course, he doesn't have a comparison
There hasn't been any optimization at all – the real question is what all the insulation and adjustments actually achieve in the end.
