Not a palace. Usable living area of 146 sqm. Total 160 sqm, split-level. The heating was offered to us like this.What kind of "palace" is this that requires an 8 kW heat pump? "KfW100", 300 sqm, location? How to determine the heating demand at least approximately without a separate meter has already been mentioned.
LOL - I don't even want to see the overall heating plan.No palace. Usable area of 146m2. Total 160m2, split-level. The heating was offered to us like that.
And the other 2 question marks? Which KfW rating and design temperature? How many sqm are heated now? 146 sqm?No palace. Pure usable area of 146m2. Total 160m2, split-level. The heating was offered to us like that.
Then I still have to talk to the photovoltaic guy. Since the beginning of the year, I have been diligently recording all meter readings of the two meters as well as the amount of heat generated by the heat pump to be able to do an evaluation. Unfortunately, I don’t understand the whole system 100% yet. I have one tariff for heat. Basic price €10.66/month and 20.52 cents/kWh and one for the household Basic price €11.69/month and 32.57 cents/kWh.
The lowest one there is. The contract states KfW 153. Exactly the 146m2 are heated. The HAR was not included in that. I can't tell you anything about the design temperature right now.And the other 2 question marks? Which KfW classification and design temperature? How many square meters are heated now? 146 sqm?
That is the application for energy-efficient building, but not the KfW rating of the building. KfW55, 40 or 40+? (probably 55...). And is the house located in the cold East or in the warm Rhineland?The lowest there is. The contract states KfW 153.
