ᐅ Underfloor heating with an air-to-water heat pump. House gets too warm when the sun is shining.

Hello everyone,
I have a general question.
We moved into our new build four months ago. The living area on the ground floor has three large floor-to-ceiling windows facing south. We have underfloor heating and an air-to-water heat pump.
It provides a really comfortable temperature inside the house, but we have a problem – whenever the sun is shining in winter, even if it’s -2°C (28°F) outside, the temperature suddenly rises to 24°C (75°F) in the living room. It gets uncomfortably warm in here, and the underfloor heating can’t be turned down quickly.
Should we assume that the large floor-to-ceiling windows are responsible for the heat gain? A photo of the south-facing side of the house is attached.
What would you do – always lower all the blinds as soon as sunlight is forecast? That seems quite annoying...
We have motorized blinds controlled by Somfy. Would you consider buying a sensor that automatically lowers the blinds at a certain temperature?
Thanks in advance for your replies.

He will set the flow rates according to the calculated values. Whether these work out well in practice, you will only find out once you live there.The calculations for our volume weren’t really great; I had to recreate and test everything myself.chewbacca12310 Jan 2020 07:39tomtom79 schrieb:
Buy yourself an IR thermometer for 15 euros, Warning – the admin messaged me about advertising in the forum and said they will ban us if we post things like this.. ?!
He also shortened my post! To some extent, I understand why, but it was just a link to my drive file. I don’t see how there could be any advertising there...
But we can’t continue with the heating right now; it’s over 15°C (59°F) outside with clear skies. Crazy—last year we had 40 days of snow, this year just once 10cm (4 inches), and it melted by the afternoon.

But continuing with the heating system isn’t possible right now; we have over 15 degrees Celsius (59°F) outside and clear blue skies. Crazy—last year we had 40 days of snow; this year only once with 10 cm (4 inches), and that melted by the afternoon.Well, I didn’t fully understand that either, but okay.The weather is really crazy, we have 10 degrees Celsius (50°F) here in Rhineland-Palatinate. Well, when it’s this warm, you also use less electricity for the heat pump.
