Pellet storage options

A year's supply of wood pellets for a detached house only occupies an area of approx. 4 m². As well as the space savings, storage of the little wood pressings also offers many other benefits:

Compact fuel

Pellets have a bulk weight of at least 600 kg/m³. For a house with 150 m² of living space, approx. 6 m³ is sufficient for one year.

You only need approx. 4 m² of floor space for storage. Thanks to flexible storage solutions, this space can be located in the cellar, in a utility room or even outside the building.

Small storage space

Compared with logs and wood chips, the compact storage space required by pellets becomes even clearer. For a 150 m² house, approximately twice as much space is required to store the annual requirement of logs for central heating and DHW heating.

Little energy giant

The cylindrical pressings made of wood waste (wood shavings and sawdust) are pressed at high pressure without chemical binding agents. With a diameter of 6 mm, they have a calorific value of approx. 5 kWh/kg.

The energy content of 2 kg of wood pellets equates to ~ 1 litre of heating oil ~ 1 m3 of natural gas. If your heating oil requirements amounted to 3000 litres per year, you would need approx. 6 tonnes of pellets for the same period.

Individual systems

The optimum means of storage and materials handling depends on the space you have available.

The traditional solution for storing wood pellets is the storage room. If no separate room is available or the available rooms are damp, then a storage tank is the ideal solution.

Direct contact with water must be avoided. Moisture causes pellets to swell up, making them unusable. However, normal humidity levels, such as those occurring in rooms throughout the year due to the weather, do not adversely affect the pellet quality.

All under control

Optionally, you can equip your storage room or storage tank with an additional level sensor. This sensor informs you of the current stock level. If the level falls below the minimum defined by you, this information appears on the boiler or as a notification on your mobile control module.

Convenient delivery

Wood pellets are delivered to order by tanker. The pellets are blown into your storage facility carefully and securely via a hose. It is therefore important that the tanker can park within a maximum distance of 30 metres from the inlet.

Your pellet store is replenished in a matter of minutes and your storage room is filled with the pleasant aroma of wood pellets.

Storage tank

The storage tank is quick and easy to install, cost-effective and dust-tight. Furthermore, the fabric is permeable to air, which makes the tank the perfect storage option for pellets. If it is protected from sun and rain, it can even be sited outside the building. Moreover, innovative storage tanks have 60 percent more storage capacity for the same space requirement.

Pellets are delivered by tanker, from which the pellets are blown into the storage room or tank by compressed air. In contrast to oil, pellets cause no unpleasant smells and are stored cleanly with accustomed convenience.

Pellet storage room

In the case of a separate pellet storage room, a smooth sloping floor with a minimum inclination of 45 degrees must always be installed. If no sloping floor is provided, the inclination is too shallow or the surface too rough, then pellets can become stuck. Not only the pellets themselves need to be high quality, but also the equipment and design of the storage room. The walls, floor and ceiling of the store must therefore be absolutely dry, as otherwise the wood pellets could swell up and fall apart.
