Air-water heat pump current consumption and data

It's quite simple, everyone has a baseline for which they are willing to pay or consume more than necessary, even if it wouldn't be required. I don't need an iPhone 12 but I want to have one, but I could just as well walk around with an Android phone like 75% of the population. It's the same with the necessary temperature in our house. Analogously in this case, an Android phone is enough for us :) It only becomes critical when someone wants something, can't afford it, but still consumes. It's only luxury if you can't afford it. That is basically not the case :)

That implies an iPhone would be better than an Android. You can certainly see it differently :). Zero problems with my Samsung and my wife is just complaining with her iPhone (battery problems at below freezing temperatures, Bluetooth failures, backup errors..) I think it's more about buying a product with promises and performance data from the manufacturer. In the end, it runs like a crutch. As a customer, you feel really fooled.

I see it that way too .

I tried working with timers over the weekend. From 3:00 to 7:00 and from 15:00 to 19:00 I heat up by 3K. In 4 hours I raised the bathroom temperature by an unbelievable 0.2K! So it makes no sense...

Underfloor heating takes up to 48 hours to respond to changes, so time programs are useless.

Welcome back to the land of crappy heat pumps and weird DTA files. Nothing changed, the flow rate remained at 1380l/h without KG and the heat pump does whatever it wants.

Last chance to integrate KG with 3x60l/h flow. Now I don't care about anything anymore. Luckily, the outside temperatures are rising, so heating the KG won't be that expensive. This results in a total flow rate of 1560l/h, which is the nominal performance. If it doesn't run consistently now, the only option left is the AI service.

: What is your guess about this? Could it actually be because the heat pump has too little flow (1380l/h)?

Welcome back to the land of shitty heat pumps and bizarre DTA files.
Nothing changed, the flow rate was still at 1380l/h without KG and the heat pump does whatever it wants.

Last chance to integrate KG with 3x60l/h flow. Now I don’t care anymore. Luckily the outside temperatures are rising, so heating the KG won’t be so expensive. That way, the total flow will be 1560l/h, which is the nominal capacity. If it still doesn’t run consistently now, the only thing left is AI service.

: What’s your guess on this? Could it actually be because the heat pump has (or had) too little flow (1380l/h)?

But how can it be too little flow? We’ve read that I modulate with 800 l/h and someone else here has a similar value? Or do you not have a modulating heat pump?

According to the manufacturer, the minimum flow rate for the heat pump is 1200l/h. Last time, I was badly below that with 1041l/h.

The nominal flow rate is 1600l/h. With yesterday's 1380l/h, I was still quite far from that and hope that's the reason. I am now at 1580l/h with the basement. I will observe it for 48 hours.
