Hello everyone,
we are about to build our new single-family house. Therefore, I ask for your help...
The question arises about the right storage system: layered storage tank with instantaneous water heater for hot water or buffer storage tank/domestic hot water storage tank:
Further, there is the question about the correct sizing of the photovoltaic system.
Here are the framework conditions:
New build with 190 sqm living space and basement
KFW 55 (1-liter house)
Decentralized ventilation system (97% heat recovery)
Heating: Novelan LAD 9 HID 1
Combination with photovoltaic system
No additional heat sources such as wood stove or solar
My heating installer has now offered me a 600-liter layered storage tank Novelan MFS 600 S.
Now the question arises whether especially for summer operation a domestic hot water storage tank with separate buffer storage tank would be better? Since then probably only the hot water storage needs to be heated. How large would you dimension this?
Would you still choose a heat pump tariff or would this no longer be cost-effective?
Thank you very much. Christian
