The EKO PLUS + boiler meets the requirements of Class 5 according to PN-EN 303-5:2012 and the ECODESIGN directive for eco-pea coal. It is a successor to the Eko Plus boiler, whose solutions have been modified to meet the latest emission standards. The controller allows remote control via the Internet, and the retort burner achieves approx. 88% efficiency. These parameters and compliance with standards make the boiler eligible for subsidy programs supporting ecological heating systems. The heat exchanger is equipped with turbulators that can be mechanically cleaned without dismantling the boiler.
Ogniwo EKO Plus + are automatic feeder boilers equipped with the intelligent eCoal.pl controller. The combination of solid and well-thought-out construction with advanced control has resulted in an efficient and user-friendly central heating boiler. The product is designed for users who do not want to spend winter in the boiler room adjusting settings and maintaining the boiler, but advanced users can still customize parameters according to their needs.
Boiler burner
The advantage of this burner is that it is entirely made of cast iron, which significantly increases its durability. The burner is designed mainly for burning coal (fine coal and eco-pea coal), but it can also handle so-called "difficult fuels". The feeder housing is made of high-quality P265Gh boiler steel and cast iron, while the screw is made of acid-resistant steel 0H18N9.
The fuel tank cover has been equipped with a sensor that informs about improper closing.
Additional advantages include:
- screw operation monitoring sensor
- feeder temperature sensor
- connector for optional fire safety device
The operation of the Ogniwo EKO Plus boiler is controlled by the eCoal.pl controller, which minimizes user involvement. The adaptive controller does not require any combustion-related settings – everything happens automatically. Of course, more advanced users can experiment with combustion parameters.
An additional advantage is the ability to connect to the Internet, allowing remote monitoring and control of the boiler via a website (example panel available here) or an Android app.
Another interesting feature is SMS notifications about boiler status, e.g. low fuel level.
eCoal.pl controller options:
- boiler operation control
- automatic combustion process
- touch panel
- weekly and weather-based programming
- summer/winter mode
- support for 4 pumps
- four-way valve support
- easy software updates
- cloud data storage
- remote access via mobile devices
- free smartphone app
The manufacturer has also ensured easy cleaning. The compact size allows easy access to the cleaning hatch located at the top. The cleaning process takes only a few minutes, and the resulting dust goes into the ash pan, which is then emptied.

Od roku jestem użytkownikiem tego kotła. Dobór mocy wg kalkulatora "na styk" tj. bez przewymiarowania. Podpięty do istniejącej instalacji stalowej. Obieg kotłowy na rurach 5/4 cala. Pełna automatyka: zawór czterodrogowy z siłownikiem, czujnik temp. zewnętrznej i wewnętrznej. Zasila 9 kaloryferów różnej wielkości + bojler 140l. Znakomity palnik żeliwny II generacji i sterownik. Przez cały czas pracuje w automacie. Znakomicie sprawdza się funkcja osuszania zasobnika paliwa. Spalanie tylko ekogroszku dobrej kaloryczności. Zawleczka reduktora ani razu nie uległa uszkodzeniu. Po nasypaniu paliwa do zasobnika na środek wlewam ok. 100 - 150 ml oleju. Smaruje się ślimak i nie ma trzasków zacinającego się węgla. Popiół jest bez niedopałów i bez szklistych spieków. Dobra wiedza z zakresu regulacji prawidłowego spalania jest niezbędna.
