Inside our house, it’s rather warm, at least 22 degrees Celsius (72°F), with bathrooms and living areas around 23 degrees Celsius (73°F). The normal outside temperature is about -13.2 degrees Celsius (9.8°F). We have already experienced several frosty nights.Yes, for us it’s around -16 degrees Celsius (3.2°F), and we’ve had many frosty nights, especially October, which was very cold. Temperatures are similar.
@Bookstar So how does the overall November look for you now?
I will turn on the underfloor heating tomorrow since the wood might only last until December, and we didn’t have any sun last week, with no sun expected next week either, to warm the rooms upstairs by 1-2 degrees. Currently, it is -8°C (17.6°F) and in recent days there have been subzero temperatures at night without any sun during the day. The temperature was 22°C (72°F) on the ground floor and 19°C (66°F) upstairs. It shouldn’t be any less than that now.

You were right, November saw a significant increase in heating demand, with temperatures almost continuously below 0°C (32°F) in the second half of the month. We used 548 kWh in November, which at a rate of 0.21 cents per kWh equals 115 euros. That’s definitely reasonable.
Last year, we consumed 660 kWh during this period, and November was almost 1°C (2°F) warmer on average. Still, we achieved a 17% reduction compared to the previous year.
The COP was 3.8 during this time. I know there are systems that exceed 4, and I’m aware that my setup isn’t optimized for top performance. But at least I no longer have to be ashamed 😀. Everywhere in the house is comfortably warm, at least 22.5°C (72.5°F), except the bedroom at 18.5°C (65°F).
I could probably lower the heating curve a bit more. I haven’t used the wood stove out of laziness for the past few weeks (need to chop more wood first 😀). Also, the water temperature is set to 50°C (122°F), which leads to higher consumption.
But comfort is much more important to me, so I don’t mind if we use a bit more energy 🙂
