And the feed-in tariff comes at the expense of the self-consumed kWh

Correct. Both compared to the purchase price each result in the respective savings. And that’s what matters.

Since yesterday, the compressor has been running continuously for 24 hours, which doesn't seem normal, right? However, the supply temperature remains steady at 30°C (86°F).

That depends on your heat pump. Fixed output or modulating?

Then everything is fine, as it regulates the power output by itself.

So, the worst-case scenario has occurred. Due to a lack of sunlight, a low heating curve, and generally gloomy weather, the room temperature in the bathroom dropped to 20.9°C (69.6°F), significantly falling below the WAF comfort level.

As a result, the household is constantly carrying around a 2 kW (2.7 hp) portable heater. If that’s not enough, they take one or two hot showers a day, have their blame-loaded spouse stoke the wood-burning stove, and also go to the sauna daily. This situation has also affected my diet negatively, mainly resulting in hot soups appearing on the lunch table.

All of this leads to a clear increase in overall electricity consumption, effectively negating the small savings made on heating electricity—much like killer cells destroying all that has been built and grown.

My youthful recklessness and sense of adventure have taught me a lesson this time; it was probably much needed.

I considered myself a superhuman when I misused the round dial of my heating system to lower the heating curve from 26.5°C (79.7°F) to 25°C (77°F).

It will be a lesson learned! Male parta, male dilabuntur!

Poor you! That can’t happen to me like that. My boss has a few absolutely perfect temperature sensors in her nose tip and fingertips: At exactly 21.0 degrees Celsius (69.8°F), she warns me that everything is still okay. At exactly 20.9 degrees Celsius (69.6°F), she starts "freezing like a dog," and then I’d have to quickly fire up the chimney. But I don’t like running it above 0 degrees Celsius (32°F) outdoors temperature, so I prevent the underfloor heating from dropping that low in the first place. It’s a method that has been tested and proven over many years. By the way: From 22 degrees Celsius (71.6°F) onward, she tends to complain about the crazy heat inside the house...
