General information
Combine economy with efficiency!
The SEG PELLET boiler uses reliable technological and design solutions that make it an exceptionally effective and proven source of heat. The boiler is adapted to the efficient combustion of class C wood pallet in accordance with the PN EN 303-5: 2012 standard. It is equipped with a self-cleaning burner. Pellet lighter cooperating with the RTC clock, lighting up and extinguishing the boiler according to the schedule, reducing the number of activities to be performed on the boiler to almost zero.
Technology and security
Heat exchanger
Efficient design for quick cleaning of the exchanger from the front. The design of the boiler exchanger ensures high heat removal from the furnace.
Flue outlet
The structure of the boiler has been designed in such a way that the flue outlet is at the rear. The use of such a solution in a central heating boiler allows the flue to be directly led out to the chimney.
Automatic feeder
Swirlers
Limit switch
Firefighter
Exhaust steering wheel

Connectivity and functionality
Simple and intuitive boiler control
Adjust the boiler operation and room temperature to your individual needs. The PLATINUM PELLET controller is programmed in such a way as to automate all processes related to the heating of your home. The owner specifies the temperature he wants to have in the apartment, and the controller will optimize combustion in this respect. Entering the advanced driver settings, you can personalize each parameter. It all depends on the preferences of the user and household members!
