KWB Easyfire

Type USV V

Variant: Storage Container
As an entry model or for customers unwilling to renounce the convenience of a KWB pellet-fired heating system despite lack of space, there is a special storage container with a capacity of approx. 300 litres which has to be filled by hand. Depending on required heating output and season, this amount is sufficient for the container to be emptied every few days or weeks.

KWB Easyfire

Type USP GS

Fuel-Extractor System: Worm Extractor with Suction Conveyor
The suction system consists of suction turbine, storage container (capacity approx. 120 litres, i.e.
no suction at night), suction hose and the modularly expandable conveyor worm. It is particularly
suitable for storage rooms situated further away from the boiler room and for storage rooms next to, above or underneath the boiler room. The pellets are extracted from the storage room by means of a worm and transported from the suction turbine by means of a hose into the storage container. Hose lengths from 25 to 30 m present no problems. The system is absolutely reliable, uses little power and has a very quiet operation due to a sound-proofing hood.
