Storage and transport solutions for Windhager pellet boilers

Pellet storage

The ideal pellet store

Requirements

The ideal pellet store is dry, offers sufficient room for a year's supply of pellets and is located on an exterior wall. A fire protection door ensures maximum safety.

The lorries that deliver a year's supply of pellets can blow them into the storage room from a distance of up to 30 metres. Ideally, a pellet store will be on an exterior wall. It does not need to be right next to the boiler room. Thanks to Windhager's innovative, dust-free suction system, hallways and rooms can be bridged with no problem.

Eight-probe suction solution

  • More storage space (1/3 and more)
  • Saves time and money
  • Safe and maintenance free


Pellet rules of thumb

Storage roomEnergy content
650 kg pellets = 1 m³ storage volume1 kg pellets = 4.9 kWh
2 kg pellets = 1 l of EL heating oil = 1 m³ natural gas
Store room dimensions with inclined supports in room = building heat load in kW x 0.9 = annual storage room requirement in m³3 m³ pellets = 1,000 l of EL heating oil = 1,000 m³ natural gas

Sheet steel hopper

Alternative solution for damp spaces

A sheet steel hopper is suited for pellet storage in damp spaces and can be installed directly in the boiler room as it is made entirely of galvanised sheet steel sections.


Advantages

  • Flexible adaptation to circumstances1) (22 types and up to approx. 10 tonnes in volume)
  • Can also be installed directly in the boiler room (legal specifications and distances must be maintained)
  • High stability and mechanical strength
  • Ideal for damp installation rooms

Fabric hopper

Alternative solution for damp spaces

A fabric hopper is another solution for damp installation rooms. The height-adjustable frame construction and conical base are also made of galvanised sheet steel. The outer shell is made of anti-static plastic fabric.


Advantages

  • Flexible height adjustment from 1.8 to 2.5 metres
  • Available in 7 sizes (up to 9 tonnes in volume)
  • Can be installed directly in the boiler room (must maintain legal specifications and distances)
  • Long service life thanks to galvanised frame construction and durable, anti-static plastic fabric
  • Ideal for damp installation rooms
  • Super quick installation involving just a few screw connections


 

Buried and outdoor hoppers

For outdoor storage

If there is no space available in the house or basement, the pellets can also be stored in a plastic tank buried in the garden.

Available sizes

Buried hoppers are available in several sizes and can be obtained from partner companies.


Advantages

  • Storage solution for use outside buildings
  • Dry, secure pellet storage regardless of weather
  • Buried hoppers with up to 6 tonnes capacity delete (on request)
  • External hopper with up to 7 tonne capacity
