Pellet boiler

Versatile and efficient, PR series boilers heat your home ecologically and economically, without compromising on ease of operation. Automatic cleaning systems reduce routine maintenance, while the PWM circulator and performance probes optimise efficiency. Built-in wi-fi allows you to stay connected at all times, even when you are away from home.

Auto-adjustment of the fumes extractor (encoder)
It keeps the RPM of the fumes motor constant, to ensure correct combustion of the product.
Hopper safety thermostat
Ensure always high safety standard, preventing the overheting of the product in case of anomaly.
1st and 2nd air auto-balancing
Primary and secondary air electronically balanced for an optimal combustion and thermal efficency.
Outdoor temperature thermostat input
The product interfaces with room temperature control devices (thermostat or contacts) to achieve the selected temperature in every room.
Flue pipe safety pressure switch
Checks the correct evacuation of the fumes and, in case of need, locks the loading of pellets, to avoid problems on the generator.
Chrono-thermostat
Chronothermostat provided with temperature control divided in four daily slots for an optimal rooms management.
Auto-relighting after black-out
Following a black out the appliance automatically re-starts after having carried out the scheduled auto-control.
Clean combustion
Increases the combustion efficency and the duration of parts subject to wear duration reducing at the same time the ordinary brazier cleaning.
