Hello everyone,
We are about to decide whether provider A or provider B will build our house. The design is exactly the same for both houses, with the difference that House A is equipped with a Dimplex air-to-water heat pump installed indoors and meets the KfW 70 energy standard. House B has a Viessmann split air-to-water heat pump and does not meet the KfW 70 standard. My advisor told me that the additional cost to reach the 70 standard would be around 7,500 euros.
How do you assess this? Both houses will be built with solid 36.5cm (14.5 inches) Poroton bricks.
Thanks in advance for your answers!
Best regards
