  • 1. Pro 1 kW heat = 0.4 - 0.9 m³ storage space - depending on the house Dämmzustand
    (inkl. Leerraum) (including space)
    2. Nutzbarer Lagerraum = 2/3 Lagerraum (inkl. Leerraum) Effective storage space = 2 / 3 storage space (including space)
    3. 1 mł Pelletsmenge = 650 kg 1 m³ pellets quantity = 650 kg
    4. Energieinhalt = ca. 5 kWh / kg = Energy content of about 5 kWh / kg

    Beispiel: Example:

    Einfamilienhaus mit einer Heizlast von 15 kW Single with a heat load of 15 kW


    = =


    5.800 kg Pellets Jahresbedarf 5,800 kg pellets annual requirement

    15 kW Heizlast x 0,9 mł / kW 15 kW heat x 0.9 m³ / kW

    13,5 mł x 2/3 = 9 mł 13.5 m³ x 2 / 3 = 9 m³

    Lagerraumgröße Storage room size


    = =


    13,5 mł : 2,4 m (Raumhöhe) = 5,6 m˛ Lagerraumfläche 13.5 m³: 2.4 m (room height) = 5.6 m ˛ storage space
    (2,0 x 3,0 Meter sollte jedoch nicht unterschritten werden) (2.0 x 3.0 metres should not fall below)

    Gelagerte Energiemenge Stored amount of energy


    = =


    5850 kg x 5 kWh / kg = 29250 kWh 5850 kg x 5 kWh / kg = 29250 kWh
    (entspricht einer Heizölmenge von ca. 3000 Liter) (equivalent to a quantity of fuel oil about 3000 liters)
