Hello,
I’m interested in knowing your current daily heating consumption.
Please provide it either in kWh for heat pumps or in m³ for gas, along with the room temperature, heated area, and energy standard (e.g., Energy Saving Ordinance 2016, KFW70, KfW 55, etc.).
I’m curious about your consumption at the current temperatures.

Goldi091117 Feb 2017 21:33That once again confirms my plan to go with the gas condensing boiler, sorry Bautraum2015.
Bautraum20157 Feb 2017 21:33But I have been living in a newly built house since October 2016, built to KfW 70 standard, supposedly equipped with the latest air-to-water heat pump heating system... So I find 1000 kWh somewhat a high number.

Bieber08157 Feb 2017 21:41Completed in June 2016, 154 m² (1,657 sq ft), 2 adults + 2 children, KfW 70 standard, 154 m² (1,657 sq ft), air-to-water heat pump, consumption January 2017: 930 kWh heat pump electricity plus 280 kWh household electricity.
It’s average; the colder it gets, the less efficient an air-to-water heat pump becomes.
Here are my latest data: https://www.hausbau-forum.de/threads/Erfahrungen-Sole-waermepunpe.13756/page-27#post-172446
We also experienced a few nights around -18°C (0°F), but the average temperature was significantly higher. However, for me, the period from December to March has always been relatively heating-intensive, while the other months required very little heating.

toxicmolotof7 Feb 2017 23:53You can definitely tell it was cold in January.
116 kWh October
263 kWh November
287 kWh December
403 kWh January (intentionally without using the fireplace)
On average, about 60-70 kWh must be subtracted for hot water.

May I share our energy consumption for January?
-Heated area approximately 180sqm (heating temperature of underfloor heating 20°C (68°F), resulting in 22°C (72°F) room temperature... Domestic hot water set to 46°C (115°F))
-Normal showering/washing habits
-3 people (toddler + 2 adults)
-Air-to-water heat pump, latest model from Vaillant
-January was cold here, down to -18°C (0°F) at night.
Result: 2000 kWh![emoji43]
That really surprised us. Is this normal? Hmm, 1000 kWh for one month is quite a lot as well. Since mid-October, we have used almost 2500 kWh, which is already a high amount. Also, what exactly do you mean by underfloor heating at 20°C (68°F) with a room temperature of 22°C (72°F)? You wouldn’t have a flow temperature of 20°C (68°F) heating the house to a higher room temperature than the water temperature itself, right?
