ᐅ Air-to-Water Heat Pump: Current Consumption and Data

It’s actually quite simple: everyone has a baseline they are willing to exceed and pay more or consume more, even if it’s not strictly necessary.

I don’t need an iPhone 12, but I want one. At the same time, like 75% of the population, I could easily use an Android phone.

It’s the same with the required temperature in our house. Similarly, in this case, an Android phone is enough for us 🙂

It only becomes critical when someone wants something they can’t afford but still consumes it.
It’s only luxury if you can’t afford it. That generally isn’t the case here 🙂

This implies that an iPhone would be better than an Android. But you can definitely see it differently 🙂. I have zero issues with my Samsung, while my wife’s iPhone constantly causes trouble (battery problems in subzero temperatures, Bluetooth failures, backup errors...).

I think it’s more about buying a product based on the manufacturer’s promises and specs. In the end, it works like a crutch. As a customer, that really feels like being ripped off.

I agree with that as well @Bookstar.

Over the weekend, I tried using timers.
From 3:00 AM to 7:00 AM and from 3:00 PM to 7:00 PM, I increased the heating by 3°C (5.4°F).
In 4 hours, the bathroom temperature only went up by an incredible 0.2°C (0.36°F)!
So, it makes absolutely no sense...

Underfloor heating can take up to 48 hours to respond to changes, so time schedules are ineffective.

Welcome back to the land of problematic heat pumps and odd DTA files.
Nothing has changed; the flow rate remained at 1380 liters per hour (l/h) without the buffer tank, and the heat pump is still operating erratically.

Last chance to include the buffer tank with a flow rate of 3 x 60 liters per hour (l/h). Now I don’t care anymore. Fortunately, the outside temperatures are rising, so heating the buffer tank won’t be too expensive. This brings the total flow rate to 1560 liters per hour (l/h), which is the nominal capacity. If it still doesn’t run steadily, my only option left is the AI service.

@Daniel-Sp: What’s your guess on this? Could it really be that the heat pump has too low a flow rate (1380 liters per hour (l/h))?

Nothing has changed, the flow rate was still 1380 l/h (0.58 gallons per minute) without the thermal store, and the heat pump is doing whatever it wants.

Last chance to integrate the thermal store with a flow rate of 3 x 60 l/h (3 x 0.26 gallons per minute). At this point, I don’t care anymore. Fortunately, the outside temperatures are rising, so heating the thermal store won’t be that costly. That brings the total flow rate to 1560 l/h (0.69 gallons per minute), which is the nominal capacity. If it still doesn’t run steadily, my only option left is AI service.

@Daniel-Sp: What’s your guess on the issue? Could it really be that the heat pump has too low a flow rate (or had too low a flow rate) at 1380 l/h?

But how can it be too low flow? We have read that I modulate with 800 l/h (0.35 gallons per minute), and someone else here with 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 1200 liters per hour (l/h). Last time, I was well below that with 1041 l/h.

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