Freestanding hydro pellet boiler that heats up to 230 m²
OPERA 28: more autonomy. More freedom. Maximum comfort.
OPERA 28 is the 28 kW freestanding hydro pellet boiler designed to heat spaces up to 230 m². A complete solution that combines power, automation and efficiency to deliver consistent comfort and simplified heating management. The large 90 kg hopper, fitted with a level sensor, allows up to 56 hours of autonomy, reducing refill frequency and making everyday management easier.
Automation and technology work together to reduce manual work and optimise operation. The ROTOX360 self-cleaning burn pot supports optimal, efficient combustion, while the helical turbulators allow automatic cleaning of the internal exchanger. The automatic ash compactor makes it possible to exceed 400 hours of operation, further reducing maintenance. With an efficiency of 91.3% and an A+ energy class, OPERA 28 combines performance and attention to efficiency in a single system.
