Hello,
we are having a Vaillant Arotherm Split VWL 75/ with uniTower VWL 78/5 IS installed.
I read on the manufacturer's website that the aroTherm split can also be used for cooling with underfloor heating (which we have), provided it is "properly designed."
Unfortunately, I couldn’t find more information. What does "properly designed" mean exactly?
We will definitely ask our contact person about this at the next appointment. I just like to be prepared beforehand to know if it will cause additional costs or what exactly needs to be done.
With another builder, we were once quoted a four-figure additional cost for the cooling function. However, I no longer remember which heating model was supposed to be installed then.

You need to develop a plan based on the house shape, floor plan, etc. Sometimes one device or one per floor may be sufficient. If you are sensitive to noise, having a fan in the bedroom is rather counterproductive. However, multiple systems are usually the easiest way to achieve the goal.
Thanks first of all for the responses.
This matches our view.
There is apparently also something called a "cold air pool," which forms near the floor and does not rise further. The warmth stays at the top. Of course, this could be improved with air circulation using a fan, etc. But it is well documented that this is not really beneficial.
So, we will be willing to pay no or very little extra cost.
I can report back on what the general contractor charges and how they justify it.

You could, of course, improve this with air circulation using a fan, etc. But that has been proven not to be very effective. I can confirm this from experience when coming home on a hot afternoon or evening after cooling with the underfloor heating system. You can really feel the cold air settling at the floor level. However, as soon as you move around the house, the air mixes quickly.

Do you want to repeat your experiences when buying a car—first buying something and only realizing later that it was a bad choice? Buying a car is not usually an impulsive purchase. You typically do plenty of research beforehand. We had bad luck with the Fiat and their goodwill policy (the clutch failed at 50,000 km (31,000 miles) and one month after the warranty ended). I never expected the battery to be located above the wheel arch, requiring the wheel to be removed for replacement. Normally, changing a battery takes about 10 minutes. I could write a book about the Fiat, but also about the auto repair shop, which really shouldn’t even be called that...
