The Niko Therm Expert series pellet boilers represent a new generation of heating systems, specially designed for the needs of Bulgarian households and commercial properties. These are three-pass, highly reliable, and exceptionally economical boilers that operate consistently even under the harshest winter conditions.
While many heating systems promise efficiency, Niko Therm Expert delivers it in real-world conditions – adapted to our climate, our installations, and the way Bulgarians heat their homes.
Robust Construction and Guaranteed Durability
Each boiler in the series is manufactured from high-quality steel with a thickness of 4 to 5 mm.
This is not just a technical specification – it is a key factor for:
resistance to heavy daily operation
protection against deformation
significantly longer service life
The internal construction includes a three-pass heat exchanger with vertical fire tubes, allowing maximum heat absorption and preventing condensation formation. This, in turn, reduces fuel consumption and minimizes component wear.
Combination with the Self-Cleaning Niko Therm RB STAR Burner
The models from the Expert series operate in full synchronization with the Niko Therm RB STAR pellet burner, which is known for its reliable automation and self-cleaning function.
The advantages include:
minimal manual maintenance
continuous and stable combustion
optimized consumption throughout the entire heating season
This combination turns the system into one of the most convenient and efficient solutions on the market.
Flexible Installation Suitable for Any Space
One of the key strengths of the Expert series is the ability to mount the burner on the left, right, or front side.
This makes the boilers ideal for:
narrow boiler rooms
spaces with non-standard layouts
limited installation areas
The boiler and burner are sold separately, but we also offer complete sets for added convenience.
