Woodchip Boilers

Woodchip boilers require a bigger plantroom than pellet, and handling woodchip is a more involved process, but the benefits are significantly cheaper running costs, especially if you have a source of wood for fuel. Woodchip also is a local fuel, it benefits the local economy, helping forestry enterprises and suppliers within the boilers locality.

The feed stock for woodchip is usually the less desirable forest residues, the thinings from forestry, offcuts and smaller sections of trees which are less use for lumber than straight, long tree trunks.

Woodchip boilers generally suit larger systems due to the special and equipment requirements, a large sweeping arm system is required to agitate the woodchip to ensure a good feed, the augers and motors are larger than pellet options and therefore the cost is high at the smaller end of the range.

Froeling produce woodchip boilers from 20kW all the way up to 1,500kW, with boilers designed to suit a wide range of fuel qualities and heating loads. The Turbomat and Lambdamat boilers are very heavy duty systems, which are specified for long heating hours with ‘rough’ fuels, where as the T4e range is a lot more compact, and concentrates on dryer, standardised virgin chip.
