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

With gas, it's pretty clear, where should an advantage come from?
With an air-to-water heat pump, it's different.
It benefits both from higher outside temperatures and, if available, the use of one’s own photovoltaic electricity.

The photovoltaic thing is tricky. Today (and also yesterday) looks great, but otherwise, for example, I haven’t produced even 20kWh in the last 30 days. I’ve practically produced more in the last 1.5 days than in the whole of December (valley of darkness).

It’s estimated that of the 32kWh, about 5kWh were used for the electric car to get to work today :-).

But as you see, even a storage system doesn’t help here. When the heat pump needs to run, that’s the end of it.

You should almost be at the "finishing" stage with the new build by now. It does not cool down that quickly.

Do not underestimate it, the screed will certainly cool down by 5 degrees overnight, even in a new build.

With that, you should almost be at "turning off" in new construction. It doesn't cool down that fast.

Well, I don't know what "turning off" means to you. But with my heat pump, heating mode "off" at temperatures below 10 degrees in the 2-day average requires a return flow of 20 degrees.
With a 2K hysteresis, that still means room temperatures of 13-14 degrees in heating mode "off" (if the TRVs are not used and are fully open or removed).

In that state, I can't completely turn off the heat pump, unless via the fuse box or if I close the TRVs, right?

Guys, I am shocked. I once typed Novelan and Alpha Innotec into a search engine. The reviews on Google are an absolute disaster and exactly confirm my suspicion: The systems are complete electronic junk that is sold at very high prices.

Since reviews on the internet are always a tricky thing, I cross-checked other manufacturers, for example Buderus. Everything was great, 4.5 stars and good reviews.

I also know many people with Buderus/Viessmann. Everything is running smoothly so far. But I have also repeatedly heard problems with the Novelan Chinese crap from acquaintances.

Apparently, they sold me absolutely overpriced electronic junk :(

Mine is going very well....

...and I can't say, as I can only look at the two heating cycles after work.

But if the spread fits and nothing else is acting up, then I am at 18kwh WP consumption yesterday, as shown in the screenshot minus the household consumption.

However, I don't fully trust the whole thing yet.
