Eko Duo – Advanced Automated Coal Boiler

The Eko Duo is the latest generation of automatic coal boilers, designed for both efficiency and ease of use. Equipped with a self-cleaning rotary cast iron burner, feeding auger, electric gear motor, a hopper, and a backdraft prevention system, it is built to offer reliable heating with minimal intervention. The automatic burner in the bottom chamber burns coal, but it can also handle pellets, grains, and other biomass fuels up to 1½". Additionally, the middle chamber allows for manual feeding of coal, wood chips, peat briquettes, and more.

Key Features:

• High Efficiency: The Eko Duo guarantees an efficiency of up to 90%, utilizing a unique design for complete heat recovery.

• TIS Tronic 481R Controller: This advanced controller adjusts the combustion process based on parameters such as user settings, weather, exhaust sensor data, and fuel quality. The controller is adaptable to modern hydronic heating systems and works seamlessly with domestic hot water, thermal storage, direct feeding, zone mixing, and more. Simply set the desired heating water temperature, and the boiler will modulate the combustion to match the load. It will automatically enter standby mode when no load is required and reignite when needed. The system provides 4 to 10 days of autonomy, thanks to a large capacity hopper. It also includes functions for circulation pumps, motorized mixing valve, buffer tank, fuel level monitoring, summer/winter mode, and thermostat feedback.

• Durability and Maintenance: The Eko Duo is built from certified boiler steel (ASTM A106) for maximum strength and longevity. The boiler features wide door openings for easy cleaning of the top heat exchanger, simple loading of biomass, and hassle-free removal of ashes. All maintenance can be performed from the front, and there is no need to unscrew any components. The boiler is insulated with non-combustible 2" insulation and coated with a high-quality multi-layer coating to ensure a long-lasting, trouble-free operation.

• Warranty: 10 years, offering peace of mind and reliable performance over time.

The Eko Duo is an excellent choice for those seeking an automated, highly efficient, and low-maintenance coal boiler for commercial or industrial use.
