BioWIN XL
The compact pellet largescale boiler
The BioWIN XL from Windhager ensures long-term, carefree heating. Every component of the pellet boiler is carefully designed and state-of-the-art. Thanks to its compact construction, it can be readily transported into the basement. The BioWIN XL requires a footprint of only 1.12 square metres, despite heat exchanger,
105 kg pellet supply container and large, integrated ash box.
Even larger buildings such as multi-dwelling houses or commercial buildings with heating requirements of up to 240 kW can be heated with the BioWIN XL. Up to four boilers are connected in a cascade for this purpose. Thanks to the flexible pellet feed, with up to eight probes per boiler, space in the storage room can be put to optimum use.
- Minimal space requirements for single boilers and on cascade
- The wear free double ignition element is durable and maintenance free
- No need to empty the box regularly, as it can hold the ash of 8 tonnes of pellets
Pellet feed
Unique, pneumatic pellet feed with 8 removal probes make inclined surfaces unnecessary in most cases.
Integral pellet fuel hopper
Large integral fuel hopper for about 135 kg of pellets enables long, uninterrupted burning phases.
Ash box
Integrated ash box ensures long emptying intervals (1-3 times a year).
Double ignition element
Zero-wear, long-life double ignition element ensures high operational safety and low maintenance costs.
RLU adapter
Prepared for operation independent of room air as a standard.
Heating surface cleaning
Long cleaning intervals thanks to fully-automatic heating surface cleaning.
Compact design
Space-saving floor space of only 1.12 m².

The fully automated pellet feed
Our experience shows that it is possible to convert from a heating system fuelled by fossil fuels to a BioWIN XL in only a matter of days. In the event of an old oil heating system, the oil tank room can be quickly converted into a pellet storage room. The fully-automatic suction system transports your pellets carefully to your BioWIN XL. No matter whether you have a special room for your pellets or a tank, we have the suitable system for every kind of store.
The optimum pellet storage room
When constructing your pellet storage room, it is important to make sure that virtually all the pellets can be removed from it. This often requires side slopes to be fitted, which can be done quickly and easily with the modular quick assembly kit for sloping floors from. Sloping floors to suit a whole number of different pellet store situations can be produced from just three basic elements: a vertical support and two different cover plates.

Excellent output with pellets
The BioWIN XL can be connected to two-unit, three-unit and four-unit cascade systems, covering heating requirements up to 240 kW.
In addition, a gas-fired peak load or backup boiler can be incorporated, for example. Specially developed by Windhager, the cascade regulation system constantly checks how many boilers as well as which ones need to be in operation to provide the required amount of heat. Balanced utilisation of the system is also ensured by checking the run times. Thanks to its considerable modulation depth, the BioWIN XL cascade operates highly efficiently at a lower output range, too.
Reliable heating
In comparison to a large boiler system, the cascade system is extremely reliable: if one unit fails to heat, you can continue heating normally with the second unit. And service work can be carried out without having to switch off the heating.
Space-saving and flexible
Even when space is tight, the BioWIN XL cascade is easily accommodated thanks to its special intermediate frame. The two-unit cascade, for example, requires just 6.8 square metres of space. The boilers can be arranged up to a distance of twelve centimetres. With a choice of a three or eight suction probe system per boiler, the cascade is also flexible in terms of pellet storage.
