  2. 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

  3. Windows +5° 0° -5° -10° -15° 2-glass windows Standard 3-glass windows Energy effective 3-glass windows

  4. Where goes the energy? Ventilation 30% Roof 15% Windows 25% Outer walls 15% Floor & Basement 15%

  5. Old plankhouse with extreme highenergy consumption Roof U=0.5 Windows U=3.0 Outer walls U=1.0 Base U=1.0

  6. Usage of energy Household electricity 5000 kWh/year Heating of the house 15000 kWh/year or around 60% Hot water 5000 kWh/year

  9. Att tänka på • 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.
