Pellet boiler Blackstar+ (12-23 kW)

Categories: Pellet boilers NBE-RTB

BLACKSTAR+ is the latest boiler series from Danish company NBE. The boiler is available in 3 power options, up to 3-12kW, 5-16kW and 7-23kW.

BLACKSTAR+ features:

Very efficient - low pellet and electricity consumption, high efficiency.

Easy to clean - top mechanism needs to be moved once a month.

Built in the best Scandinavian design tradition with a long service life.

  • High level of fire protection, multi-level electronic and mechanical protection,
  • Cleaning with compressed air is more effective than mechanical cleaning.
  • Stainless steel flue gas flow turbolisers are used to increase boiler efficiency.
  • Large ash container. Which needs to be cleaned every few months, that is by shaking off 2-3t of pellets
  • A conveyor automatically transfers the ash to the ash box located at the front of the boiler. The boiler can use the entire water heat exchanger as the ash has not covered it.
  • The vertical heat exchanger ensures that most of the ash falls to the bottom of the boiler and does not accumulate on the boiler walls,
  • Mechanical cleaning by means of handles at the top, these move the mechanical heat exchanger cleaners.
  • The cleaning process does not create dust in the boiler room.
  • The O2 sensor continuously adjusts the air/fuel ratio to ensure optimal combustion.
  • Low water content in the boiler for faster warm-up and more economical summer operation.
  • Highly efficient motors and pellet feeding process, low electricity consumption.
  • Modulation of the boiler output depending on the amount of heat required, 90 possible output variants, output range 10-100%.
  • Manufacturer: Denmark
  • Manufacturer's warranty from 24 months

Energy efficiency class: A+

Needs to be combined with a pellet bunker, models of which can be viewed by clicking here:
