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 Lagerraumvolumen (inkl. Leerraum) 13.5 m³ volume storage space (including space)

Nutzbarer Rauminhalt Effective capacity


= =


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)

Break -in fire
A series of three break-in fires are required. The first is to raise the surface temperature of the stove to 200 degrees. Another is to raise the surface temperature to 300 degrees. And yet another is to raise the surface temperature to 400 degrees.
