Good day. Perhaps someone here can give me a benchmark for my new underfloor heating system in the new multi-family house. My first heating season has been running since this winter. I strictly adhere to the ventilation guidelines (shock ventilation for max. 5 minutes at least twice a day). The building already seems very dry. The humidity in my apartment is about 40-45%. I also follow the guidelines on how to properly heat with underfloor heating. (All thermostat regulators are always set to a comfortable temperature. Max. 22 degrees in the bathroom. So all rooms are heated, even if the guest room is hardly used. I do not adjust the room thermostats when I leave the house or am away for 1-2 days). The flow temperature in the heating distributor is usually around 22 degrees. Now I am interested to know if my heat demand is more or less okay. I have about 6 kWh per m2 in the coldest month January for 80 m2, about 5 kWh in December, and about 2.5 kWh in November. Is that a lot? Normal? Or even low? PS: The multi-family house Kfw70 is heated with pellets. No ventilation system. One person in the apartment, employed, location east-south facing the apartment (so often sun exposure) Many thanks!
