H4EKO‑D MAX 25 – 55 kW wood boiler with manual loading
The gasification boiler for wood with manual loading has an efficiency of up to 90.5%, is ecological and has a large loading chamber where logs longer than 0.5 m can be burned.
5th emission class and minimum harmful emissions.
Money in the house
The high efficiency of the solid fuel boiler saves heating costs.
The electronic control unit controls the entire heating system.
The boiler has a large loading chamber and is intended for burning wood even half a meter long.
Simple setting and operation of the boiler, which is already set to the required output from the factory. Before flooding, all you have to do is set the primary and secondary air flaps to the marked line and you can start heating with certainty of the required output.
Modulated fan speed - the fan modulates its speed from 0% to a maximum of 100%. The output is thus adjusted according to the actual and required water temperature in the system.
Electronic control unit - the control unit can control not only the boiler, but also all elements of the heating system. So you don't have to pay extra for superior modules controlling mixing valves, hot water heating or storage tank. Everything is provided by the boiler control unit itself.
Possibility to connect to the web - for an additional fee, the boiler can be connected to the Internet and monitor its operation, history or change settings via phone or PC.
The boiler includes a cooling loop that protects the boiler against overheating.
Fuel burn-out signaling in the loading chamber - a message about running out of fuel is displayed in the upper right corner of the control unit display. The customer thus knows without any problem when he can open the boiler and add fuel. In addition, when you connect the boiler to the Internet, you can see the display of fuel burning out of fuel on your mobile phone.
Adding fuel without smoke in the boiler room - when the exhaust flap is opened, the fan speeds up and it then sucks the smoke from the loading chamber into the chimney through the flap. This takes about 10 to 20 seconds, after which you can open the door without smoke escaping into the room.
The boiler is able to maintain a steady-burning layer - in this case, the customer has a choice. Either it can quickly heat the water in the storage tank with maximum boiler output and perfect combustion with high efficiency and maximum fuel utilization. Which will bring him, for example, one day without the need for flooding in the boiler. The second option is to try to keep the hot layer in the boiler as long as possible so that the boiler does not go out.
The boiler is easy to maintain and clean thanks to simple access to the heat exchanger.
Economical and ecological operation
The boiler has a high efficiency of up to 90.2%, which means efficient use of fuel energy.
Low wood consumption together with a large loading chamber reduce the frequency of adding fuel.
The storage tank will further reduce the loading frequency, when its connection is a necessary for the correct operation of the boiler.
Boiler meets the conditions of ecodesign and 5th emission class.
High-quality combustion produces very low emissions even without the use of a lambda probe or other devices.
Electronic elements with a long life are used in the boiler.
5-year warranty on the heat exchanger when the boiler is installed by a trained installation company in accordance with the operating instructions.
Protection of the combustion chamber - the loading chamber of the boiler is equipped with protection plates that protect the heat exchanger from the effects of fumes created in the loading chamber.
