Eko Duo is the last generation ofautomatic coal boiler. It is equipped with a modern self-cleaning rotary cast iron burner, a feeding auger, an electric gear motor, a hopper and a backdraft prevention system. The automatic burner in the bottom chamber burns coal but also pellets, grains and other biomass up to 1½". You can also manual feed coal,wood chips, peat briquette and much more using the middle chamber. The unique design allows complete heat recovery. The boilerhas a guaranteed efficiency of 90%.
TIS tronic 481R master the combustion process depending on user parameter, weather, exhaust sensor and fuel quality. The controller easily adapt to any modern hydronic heating system and combine with domestic hot water, thermal storage, direct feeding, zone mixing design and more. Simply enter the setpoint heating water temperature and the boiler will modulate the combustion to match load. If there is no load the boiler will standby and reignites when needed. The automation with the large capacity hopper provides 4 to 10 days autonomy. The controller also includes functions of circulation pumps, motorize mixing valve, buffer tank, fuel level, summer/winter mode and thermostat feedback.
Eko Duo is manufactured with the finest certified boiler steel ASTM A106. The wide door openings make easy cleaning of the top heat exchanger, middle loading of biomass and removal of ashes from the bottom. All maintenance is performed from the front and there is no need to unscrew anything else. High-quality multi-layer coating, non-combustible 2" insulation, and thermal protection systems ensure long-term and trouble-free operation.
