Experiences with brine heat pump

Addendum: I cannot precisely limit the energy quantities to one year because I did not exactly record the status at move-in in November 14 or in November 15, but I will observe the next year in order to determine the annual performance factor accurately.

But that doesn't change the fact that the unit not only cost very, very high investments, but also runs very poorly – the heat really costs you a lot, so the heating system will practically never pay off.

Sure, nice that you are satisfied – but that can also be done, somewhat exaggeratedly, at half the cost.

I don't want to know how the heat pump cycles...

The cycling can be configured (within limits) (e.g. adjust the hysteresis of the heating circuit). The advantage of relatively frequent cycling with brine is a higher brine temperature compared to long run times, but if the cycles are too short, the heat pump does not operate efficiently enough again; here you have to find a good balance for the respective system (the thermal storage and the inertia of the screed are large enough anyway, so you can "play" well with the values). According to other forums, the wear of the device is actually not a problem nowadays.

I also didn't say that the lifetime suffers, but that it runs inefficiently and probably cycles endlessly.

And with two (!!) buffer tanks, you can hardly save anything anymore...

True, there is no approach in all that blah either, but the main thing is to talk a lot.

Thank you for the valuable information. Apparently, you didn’t read the blah after all. And try to find a valuable piece of information in your last posts. I am hereby already requesting a mod to delete our posts because you apparently ended up in the inappropriate mode. PS: I honestly hope that no construction stress is to blame.

But the main thing is that your stage here still stands for a while - what a chatterbox you are.

And no, I’m not stressed about construction - otherwise I definitely wouldn’t be hanging out here.
