The future for pellets

BioWIN XL

Pellet central heating boiler

10 to 240 kW

Pellet Heizkessel BioWINXL

BioWIN XL

The future for pellets

High levels of comfort, low level of maintenance

  • Fully automatic burner bowl shake-out
  • Long ash emptying intervals (just 1 to 3 times per heating season)
  • Eight removal probes for pellet removal with virtually no loss of space
  • Easy to take into buildings thanks to compact design (1.12 m²)

Low operating and maintenance costs

  • Pays back faster than oil and gas systems
  • Metered and therefore economical heat production
  • Robust and particularly durable stainless steel burner
  • Satisfies all emissions-related requirements

Reliable and safe

  • Permanently efficient and clean operation
  • Zero-wear, double ignition element and long-life stainless steel burner

World first 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).

Sliding ash grate

Patented sliding ash grate running in the opposite direction ensures the complete removal of ash from the burner.

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.

BioWIN XL

Fully automated pellet feed

 

To provide a follow-up supply of pellets, Windhager offers a fully automatic, patented feed system consisting of a changeover unit and up to eight removal probes.

Advantages:

  • 8 probes can usually take the place of an inclined floor and therefore prevent large amounts of lost storage space
  • Up to 8 removal points make the system incredibly reliable
  • The storage room's position is independent of the heating room's position
  • Totally maintenance-free system
  • No moving parts and no electrical cables necessary in the storage room
  • Function check
   

Cascade

Intelligent, flexible and safe

Larger buildings such as multi-dwelling homes or commercial properties can now be heated particularly efficiently and reliably with pellets: the BioWIN XL can be connected to two-unit, three-unit and four-unit cascade systems, thus providing for heating requirements ranging from 10 to 240 kW.

Intelligent

  • Serial or simultaneous starting of the boiler
  • Efficient operation thanks to continuous checking of how many and which boilers must be running
  • Balanced utilisation of the boiler with run-time checking ensures a longer service life
  • Highly efficient even at low performance thanks to the extensive depth of modulation
  • Integration of external heat consumers (e.g. swimming pools and heating fans)

Flexible

  • Combinable with different boiler power ratings
  • Low space requirement due to intermediate frame (6.8 m² for double, 9.6 m² for triple and 12.4 m² for quadruple)
  • Optional 3 or 8 suction probes per boiler for a variety of storage rooms

Safe

  • Enhanced operational safety due to multi-boiler mode
  • Service work possible with no heating interruption
  • Also combinable with 1 peak load or emergency boiler
