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

I wouldn’t consider those few euros worth it. The slightly warm tiles were already very comfortable in the bathroom this morning. The night was very cold again, with minus 4°C (25°F).

I don’t mind the extra cost right now either. But for the past two months, it’s been more of an effort issue because of the manual daily adjustment.
You remember.

But do you want to go through all that every year? Adjust the heating curve, set the heating limit, choose the automatic mode, and that's it.

I also wouldn't completely turn off the heating element. When the first strong frost comes, the heating system may run into faults and shut down. The heating element won't activate, and your pipes at the unit could freeze.

Our heating still runs occasionally. This morning it was -3°C (27°F) outside. It’s still too cold for me to switch to hot water only.
2950 kWh of heat including hot water (district heating) and 435 kWh of electricity drawn from the grid, with a total consumption of 1150 kWh.
Performance is still going quite well as expected.

A cozy 22.5 degrees Celsius (72.5°F) in the bathroom this morning, with the heating running for 5 hours yesterday evening. Without it, the temperature would probably have been around 21.2 degrees Celsius (70.2°F). Worth the extra cost to me 🙂

I would almost bet that at least you wouldn’t notice the 1.3 degrees Celsius (2.3°F) difference upstairs.

@halmi I’m not very keen on manually increasing the temperature during the day, so starting in October (for autumn) I’ll test the optimized setting that was used in winter without sunlight. It was just a shame not to do this from mid-February with so much sun.

Regarding the electric heating element, it has been completely off this year and we all know how the temperatures have been. Since the optimization at the end of January, the heat pump has been working very well and efficiently without any complaints. By the way, the domestic hot water is still only heated by the heat pump; the electric element is off there as well.

I had everything set up this way because when electric heating elements are installed everywhere, a fault usually isn’t noticed by a normal user until the electricity bill arrives.

As mentioned, this works fine until the heating system is installed and then everything outside starts to freeze.
