Construction of a central heating boiler

Automatic feeder

The automatic feeder feeding pellet fuel is an element that significantly increases the comfort of using the boiler. Its main features are:

  • Maintenance-free fuel supply - pellets are automatically transported from the tank to the burner, eliminating the need for manual feeding.
  • Quiet and smooth operation - solid construction and high-quality mechanisms ensure reliability and minimize noise.
  • Time saving - the large capacity of the tank allows for long-term operation of the boiler without the need for frequent fuel refilling.

The automatic feeder guarantees the continuity of the combustion process and optimal boiler efficiency, with minimal involvement on the part of the user.

Limit switch

The boiler is equipped with a limit switch. The safety devices are located in the boiler door and in the tank flap. Each time the door is opened, the burner and other boiler elements are automatically stopped until they are closed again.

Swirlers

Swirlers are a solution that:

  • Increases heat exchange efficiency - swirlers cause turbulence in the exhaust gases, which improves heat transfer to the water jacket.
  • Reduces fuel consumption - better heat exchange means lower energy losses and more economical operation of the boiler.

Horizontal convection channels | shelf

Efficient design adapted for quick cleaning of the exchanger from the front. The construction of the boiler exchanger ensures high heat collection from the furnace.

Flue outlet at the back of the boiler

The boiler design has been designed in such a way that the flue outlets are located at the back of the boiler. The use of such a solution allows for the flue to be led directly to the chimney.

Firefighter

Protects the fuel in the boiler tank from ignition.

Exhaust gas guide

Slows down the exhaust gas outlet, stopping and burning it in the combustion chamber.
ATTENTION!
Any interference with the boiler’s design is prohibited and will void the warranty. Attempts to install additional grates or components that allow the combustion of fuels other than those specified by the manufacturer are prohibited.

Ecology and savings

Using pellets as fuel is not only about caring for the natural environment, but also about real savings in heating costs thanks to the high efficiency of the boiler. As a user, you also have a guarantee of the availability of this fuel, because Poland is one of the main suppliers of this fuel in Europe and in the world.

Pellet burner

The SD DUO BIO 16-34kW boiler is equipped with a pellet gutter burner. The burner has been designed for maximum combustion efficiency and minimizing harmful emissions. The gutter burner is adapted to burn wood pellets compliant with the 303-5:2021-09 standard.
The Gutter burner uses an automatic ceramic igniter that offers:

  • Fast ignition – the igniter reaches high temperatures in a short time.
  • Long service life – high resistance to temperature and mechanical wear.

    Modern control

    The intuitive PLATINUM PELLET controller enables precise management of the boiler operation. Optional accessories, such as the ecoNET300 Internet Module, and the ecoNET24 application provide real-time monitoring of device information and device control via the Internet.

    Controls

    PLATINUM PELLET Controller

    The PLATINUM PELLET controller is the heart of the boiler management system. Equipped with an intuitive interface with a color touch screen, it allows easy and precise setting of the device’s operating parameters. The device supports:

    • One mixing circuit C.O.1 with a room thermostat – allows for precise adjustment of the heating water temperature and rooms.
    • Pump (C.W.U., C.O., additional) – manages additional heating zones such as underfloor heating or domestic hot water control.
    • RTC clock – allows programming of the weekly boiler operation schedule.
    • Weather control – allows programming of boiler operation modes depending on the weather or time of day.
    • FuzzyLogic & PID – monitors the boiler operation, allows for current viewing of operating parameters and diagnostics of possible irregularities.

    The controller is also compatible with the ecoNET300 internet module, which allows for remote control of the boiler using a smartphone or computer from anywhere.
