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

Ok, understood.

But I think this is more a job for the factory service. As a first step, I would report a fault and provide them with the .dat file.

Which software version do you have installed?

The heating technician won’t be able to fix it. I also think it’s best to contact the manufacturer’s customer service.
Due to COVID-19, this can often be done over the phone. You know your system well, so it should also work through your mobile phone.

I just did some quick Google research. The missing flow rate is always mentioned when the temperature difference rises too much. Where do we currently stand on that?

In one screenshot, the flow rate is 1380 l/h (580 gallons per hour), and in the other, it is 1580 l/h (700 gallons per hour). So that’s not the cause either. Last month, I tried many things to reduce the temperature difference, but nothing helped.

It’s not just the temperature difference but also the fluctuations in the return temperature. Because of that, I had a total house energy consumption of 43.5 kWh yesterday. You know what temperatures we had yesterday—between 3-7°C (37-45°F) outside.

I even tried to ignore the temperature difference of 8-9K (8-9°C / 14-16°F) because I thought, “whatever.” But it really costs me money when the heat pump starts again after 45 minutes, even though it ran for 7 hours before, and the floor is noticeably “hot.”

Have you roughly calculated the flow rate using the Tacosetters to see if it makes sense? With or without a basement?

All values were set and read directly on the Taco setter itself.

- 1380 without basement
- 1560 with basement

Thanks for Googling :-)
