Underfloor heating air-water heat pump. House too warm when the sun shines

But a heating system is much more complicated than a television.

This is not the case. People are just spoiled by modern possibilities. I can vividly remember the time when nothing worked with a television without studying a manual, and nowadays, as soon as you want to go beyond the options granted by the manufacturer (depending on the manufacturer, the settings can also be very rudimentary) for a television, reading the manual is necessary. It is similar with heat pumps. Any child can operate a refrigerator as well. (It is also a heat pump.) But this is because the manufacturer only installs a thermostat and that’s it. With a larger system like in a house, it’s a bit different. Here, the manufacturer does not know what will ultimately be connected to it and only supplies the unit and recommendations. What is then made of it is up to the heating engineer and the end user. One sets the parameters based on wishes and needs, and the other has the task of fine-tuning. Or you just keep having the other come until everything fits.

If a builder is reading this who is still choosing their service providers: Choose those who love their profession and the installed technology.

I can't choose my heating specialists myself, but he apparently worked for 6 years in factory customer service for Daikin. Therefore, theoretically, he should be able to work quite well. At least, according to information from phone calls with him about technical possibilities, he seems to have quite adequately optimized his own house. What he then delivers, however, or may have delivered previously during customer service calls, is very questionable.

The corresponding perception of warmth after the heating is adjusted is not the heating technician's, but the building owner's.

I have now also played around with the heating curve so that it is 22.5° for me. All thermostats/valves open. However, I do not know if the settings are correct.
My heat pump also cycles like crazy.

Just make a thread, otherwise there is a forum for that but I am not allowed to name it.

I now believe that the Novelan WP is particularly large technical rubbish. You really have to completely close the overcurrent valve and manually adjust everything. That's why I would prefer gas. The system always works flawlessly without adjustment and consumption is also appropriate.

My Novelan still cycles twice a day and has an average compressor runtime of 45 minutes.
