The size of the required storage space depends on the building‘s heating load, but should be chosen large enough
to store 1.5 times the annual fuel quantity.
If the unusable room volume is taken into account, the following rule of thumb results:
Per 1 kW heating load = 0,4 - 0,9 m³ Storage room - depending on insulation status
of the house (incl. empty space)
Usable storage space = 2/3 storage room (incl. empty space)
1 m³ Pellet quantity = 650 kg
Energy content = ca. 5 kWh / kg
6.2 SIZE OF THE PELLET STORAGE ROOM
06 PELLET STORAGE ROOM
EXAMPLE:
Single-family house with a heating load of 15 kW = 5,800 kg pellets annual requirement
15 kW heating load x 0,9 m³ / kW = 13,5 m³ Storage space volume (incl. empty space)
Usable volume = 13,5 m³ x 2/3 = 9 m³
Storage room size = 13,5 m³ : 2,4 m (room height) = 5,6 m² Storage space
(However, it should not be less than 2.0x3.0 metres)
Amount of energy stored = 5850 kg x 5 kWh / kg = 29250 kWh
(corresponds to a heating oil quantity of approx. 3000 litres)
