Since you often read about humming noises in houses and then see an air-to-water heat pump mounted on the wall, I would avoid that. The same applies to indoor installation without a proper base. Of course, the heat pump is decoupled using rubber vibration isolators. The same applies to the pipes, which are all exclusively separated from the building structure through insulation.
I have paid great attention to acoustic decoupling for all the pipes.

Last night, the circuit breaker on the construction power distribution unit tripped. The cable reel, which the insolvent construction company kindly left behind along with their scrap and work materials, burned out.
Then the heat pump, of course, completely froze up...
Not really needed anyway...
Just yesterday, when the screed was supposed to be heated.
Now I need several days to raise the temperatures inside the house again. Would it maybe make sense for you to also use construction dryers there? Can you now comply with the specified screed heating schedule?
We also use dryers, but below 15°C (59°F) they are not very effective. The heat pump is now running at 8 kW, but it takes time for the entire mass to warm up again.
Normally, the pump restarts immediately, but after a certain period it simply freezes up. Then you are out of luck. The same applies if it were to fail at night during these low temperatures.

daniel1985ffo16 Feb 2021 08:32You definitely cannot achieve the required temperatures for screed heating with just a heat pump. We also have a heat pump from Alpha Innotec.
However, a mobile boiler was added and connected to the heating system for the screed heating, which provided an additional 21 kW.
It ran for 6 weeks. Without the heat pump alone, we would not have reached the necessary temperatures.
Regarding mounting the heat pump on the exterior wall of the house, every plumbing company advised us against it because of the humming noise.
Ours is installed 50 centimeters (20 inches) in front of the house on a concrete base, and even there the humming noise at full load is enough for me.
