Advantages
Modern Approach
Today’s technology goes hand in hand with quality.
Small boiler size
The boiler is small in size but highly efficient.
Czech tradition
Since starting boiler production in 1959, we have gained generations of experience.
Cost Saving
The solid fuel boiler’s high efficiency saves heating costs.
The brown coal boiler with manual feeding combines classic heating with modern technology that guarantee high efficiency.
In addition, you can add a pellet burner for the boiler’s automatic operation and start combining fuels.
Easy Operation
- The coal boiler has a large hopper so that you don't have to refill too often.
- Easy to regulate
- The draught regulator ensures automatic power control
- Built-in cooling circuit for safe operation
Economic operation
- Efficiency up to 84.2 %.
- Low fuel and electricity consumption.
- It belongs to emission class 4 and meets ecodesign conditions.
Small size
- It is also suitable for small boiler rooms with low ceilings.
- Boilers with an output of 16 kW and 20 kW can also fit through a 60 cm width.
Boilers long service life
- Warranty 5 years
- The boiler sheet thickness of 5 mm guarantees a long service life
