Looking at the house you have to consider:

• Which year the house was built and ev. improvements

• Number of residents

• Living area (heated area)• Energy consumption

• Plot of land and its location

Kostnadseffektivitet

• - 1990: Vedeldning

• 1990 - 2005: Bergvärme

• 2005 - ? : Sanyos CO-2 teknik

Borrhål

• Tidigare energiförbrukning ska kunna motsvaras av värmepumpen.

• Viktigt att kunden håller en så låg framledningstemperatur som möjligt.

• Fler radiatorer eller luftkonvektor sänker framledningstemperaturen.

• Tumregel: Framledningstemperaturen bör aldrig överstiga 50°C, för optimal besparing.

• Rekommendera alltid markstativ.
