Description
EKOTEK DUO – modern, economical and environmentally friendly heating
EKOTEK DUO is an innovative heating solution that enables efficient and ecological combustion of both firewood and wood pellets. The device complies with the current PN-EN 303-5:2021-09 standards, which confirms its high quality and compliance with applicable requirements.
The steel boiler is designed for manual loading of seasoned wood, and thanks to the use of a modern, self-cleaning pellet burner, it ensures convenience of use without the need for frequent supervision. The automatic fuel feeding and combustion system makes the operation of the device максимально simplified, and the heating process runs almost maintenance-free.
The boiler construction is based on a durable heat exchanger made of high-quality steel with a thickness of 6 mm, which guarantees long service life and resistance to intensive operation. A properly designed combustion chamber and an optimized heat exchange system allow achieving efficiency of up to 93%, which translates into lower fuel consumption and higher energy efficiency.
The device meets the requirements of Class 5 emission and Ecodesign standards, which means low pollutant emissions and environmentally friendly operation. This is confirmed by appropriate quality certificates.
EKOTEK DUO is equipped with an intelligent control system that automatically adjusts the boiler operating parameters to the current heat demand. Thanks to this, it is possible to maintain a stable temperature in the building while reducing heating costs. There is also the possibility to expand the controller with an internet module, enabling remote monitoring and management of the heating system.
