Essential Information

The SD DUO BIO 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 wood pellets in accordance with the norm 303-5:2021-09. 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 at the boiler to almost zero. Thanks to the option of connecting the ecoNET300 internet module to the boiler, you can control the boiler’s functions using a phone, tablet, or computer.

Key benefits

Z

Heat exchanger

Horizontal convection channels | regimental
Effective design for quick cleaning of the exchanger from the front. The design of the boiler exchanger ensures high heat removal from the furnace.
Z

Flue outlet

At the back of the boiler
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.
Z

Limit switch

For the sake of your safety, the boiler is equipped with a limit switch. The end protection system is located in the boiler door. Each opening of the door causes the burner and other elements of the boiler to stop working automatically until they are closed again.
Z

Firefighter

It protects the fuel in the boiler container against ignition.
Z

Exhaust steering wheel

It slows down the exhaust gas outlet, stopping and burning them in the combustion chamber.
Z

Automatic feeder

The PLATINUM PELLET controller, based on the information received from the sensors, determines the demand for fuel and doses it the right amount. The process of fuel combustion itself is therefore very economical, ecological and does not require additional service on the part of the user.
Z

Swirlers

The swirlers installed in the convection channels effectively reduce the speed of the exhaust gas outlet while maintaining high heat reception through the water jacket.

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!

Pellet burner

Gutter burner – for pellets

These are one of the most popular pellet burners on the market. The burner is equipped with an automatic ceramic pellet igniter, which allows it to be quickly ignited and extinguished. The design of the burner allows you to quickly reach a high temperature of the boiler. All functions of firing up the furnace and fuel dosage can be set in accordance with the current needs of the user.

Key features:

E
Fuel: Pellet
Ecological fuel such as pellets, also known as biomass, is produced by pressing wood waste such as sawdust or shavings. This completely natural fuel turns into biodegradable ash after burning.
E
Ceramic pellet lighter
Forget about manual boiler lighting. One click is enough and the automatic ceramic igniter ignites the fuel fed to the burner. Automatic igniter in conjunction with the RTC clock allows you to program the entire week of operation of the device. The device operation clock can be set separately for SUMMER and WINTER mode.
