Advantages of the PROSAT HYBRID DUO Boiler:
PROSAT HYBRID DUO is a modern and versatile heating solution that combines the convenience of automation with the independence of traditional wood combustion. It is an ideal choice for users who expect comfort, savings, and reliability in all conditions.
- 2 operating modes: automatic (pellet) and manual (wood), allowing you to adjust the heating method to your current needs and fuel availability
- Fully automated operation: the boiler independently controls the entire combustion process – from automatic fuel dosing, through automatic ignition, to maintaining a stable temperature and flame control
- Automatic mode switching: after the wood is burned out, the boiler automatically activates the pellet burner, ensuring uninterrupted heating without user intervention
- Flexible burner installation: possibility of mounting the burner at the front or on the side of the boiler for easy adaptation to the boiler room layout
- Ideal for small spaces: compact design makes it perfect for boiler rooms with limited space
- High efficiency: thanks to the multi-pass rear flue design, the boiler effectively utilizes combustion energy, resulting in lower fuel consumption
- Flue gas turbulators: improve heat exchange efficiency, enhance combustion, and significantly reduce energy losses
