Pellet boiler Extraflame PK 15

New generation pellet boilers with automatic cleaning systems for cast iron brazier and exchanger.

The effective automatic cleaning systems, the numerous sensors for combustion control and safety and the selected top-quality materials, make these devices a complete and reliable solution at the service of comfort for your home.

Combustion chamber in thick steel, fire door and brazier in cast iron. Self-cleaning burn pot with brushless motor. Fast ignition with ceramic igniter. Innovative adaptive system to adjust and even the combustion air inlet. Shell and tube exchanger with automatic cleaning.

Brushless gearbox for pellet feeding and minimum pellet tank level probe for an optimized fuel feeding.

Hydraulic connections at the top and circulator with PWM control. Equipped as standard with safety valve 3 bar, expansion tank and air relief valve.

Black display mask with Wi-Fi module for an easy and efficient management.

Auto-adjustment of the fumes extractor - encoder

Auto-adjustment of the fumes extractor - encoder

It keeps the RPM of the fumes motor constant, to ensure correct combustion of the product.

Auto-relighting after black-out

Auto-relighting after black-out

Following a black out the appliance automatically re-starts after having carried out the scheduled auto-control.

Chrono-thermostat

Chrono-thermostat

Chronothermostat provided with temperature control divided in four daily slots for an optimal rooms management.

Clean combustion

Clean combustion

Increases the combustion efficency and the duration of parts subject to wear duration reducing at the same time the ordinary brazier cleaning.

Flue pipe safety pressure switch

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.

Hopper safety thermostat

Hopper safety thermostat

Ensure always high safety standard, preventing the overheting of the product in case of anomaly.

Outdoor temperature thermostat input

Outdoor temperature thermostat input

The product interfaces with room temperature control devices (thermostat or contacts) to achieve the selected temperature in every room.

Primary and secondary air auto-balancing

Primary and secondary air auto-balancing

Primary and secondary air electronically balanced for an optimal combustion and thermal efficency.
