Hello everyone,
In the energy performance calculation of the house we are interested in buying, the following is stated:

I think the energy demand is relatively low. The living area is estimated at approximately 145m² (1560 sq ft) in the specifications.
However, the heating costs of about 1200 euros per year seem quite high to me for such a good demand value, since I often read on this forum that many only need around 600 euros.
The heating system is a Rotex HPSU Compact.
Am I missing something?
Thank you.

By the way, the values with the unit kWh/m2a are calculated using the usable floor area, not the living area. The area should be indicated somewhere in the calculations. Important note for all home builders with an unheated basement.
