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. Fuel: dry wood.

Easy operation

The boilers have large a 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.

Long life

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.

Internet Module CS

The Internet module connects your boiler with an application that continuously monitors the boiler’s operation and also stores its operating history in easy-to-read graphs. It accurately displays the operation of the heating system components and, hence, you can change the set parameters. With this module, the heating can be activated remotely.

At the same time, the online system enables sending error and information messages to your smartphone.

You can preview our online system at www.opop.emodul.eu. After clicking on “Test account,” you see an example of a boiler connected to our online system. And when you click on “Map” you see all our boilers connected online throughout Europe.

RT10 Universal Room Thermostat

RT 10 Universal room thermostat is designed to control and monitor room temperature, central heating temperature and DHW temperature. The device contains a weekly heating programme and works with four mixing valves (using other equipment) and includes a parental lock to protect against unwanted setting changes.

The thermostat has an easy-to-read large graphic colour touch screen that makes it easy to read and change thermostat parameters.

Furthermore, you can change the temperatures of both the boiler and, for example, individual heating circuit temperature, storage container, DHW tank and so on.

The package also includes a structure that facilitates wall mounting.

If the boiler is connected to the Internet, it’s also possible to remotely change the temperature in the building using a free application on your phone.

RT10 Thermostat

CS260 Wireless Module

The wireless module is an additional accessory to the RT10 room thermostat. Enables a wireless connection between the thermostat and boiler.

However, the wireless version needs mains power. Therefore, the thermostat is connected in the room to a 230V socket and from the thermostat, the signal is sent wirelessly to the boiler room, where it is processed by a receiver connected to the boiler.
