Hello everyone,
We have been using the cooling function of our air-to-water heat pump for a few days now. At a perceived temperature of 38°C (100°F), we have 22-23°C (72-73°F) on the ground floor and 24-26°C (75-79°F) on the upper floor. I had hoped the cooling effect would be more noticeable.
On the upper floor, we have lowered all exterior roller shutters (made of aluminum). Downstairs, only where the sun shines through.
Are these good values or rather low? What are your experiences?

We were promised cooling of 6-8 degrees Celsius (43-46 degrees Fahrenheit).Yes, maybe on the first day… but when the sun shines for several days in a row, that’s when the cooling stops and the heat returns._Ugeen_ schrieb:
I guess I will have to get a portable air conditioner for the really hot days after all.Don’t do that. Get a proper fixed system instead. Install it at the highest point and enjoy comfortable temperatures.Mycraft schrieb:

Don’t do that. Get a proper fixed system. Install it at the highest point and enjoy the comfortable temperatures. What exactly does the “highest point” mean?

Don’t do that. Buy a proper fixed system. Install it at the highest point and enjoy the comfortable temperatures. Regarding point 1: We were told something different here as well. We already used thicker insulation between the attic and the upper floor, even though they said it wasn’t necessarily needed. Probably nonsense again.
Regarding point 2: On the upper floor, the sloping roofs near the windows don’t really leave space for a fixed system. You need to position it close to the window, right? Do I need multiple outdoor units for several rooms?
Insulation certainly helps in both directions, meaning it keeps heat out. But—and this is a big but—insulation is also meant to retain the heat already inside the house. Otherwise, you might end up with a sauna effect without taking additional measures.
No, you don’t have to install the system near the windows. What’s more important is that the air can move freely, ideally in all directions. That’s why open floor plans are ideal.
The exact setup of the system needs to be worked out in detail. It’s also a matter of cost. Of course, you can have a separate indoor/outdoor unit for each room, but there are also multisplit systems where one outdoor unit serves multiple indoor units.
