The boiler proper is constructed as a body of three chambers situated one above another. The two upper chambers serve for the gasification of the wood, as you are familiar with from the classical gasification boilers that we produce as the standard. In the third, lowest chamber, is installed the required burner at the front, inlaid by ceramics to ensure the optimal quality of burning. Both the systems are separated by a water jacket so that they do not interfere with each other and, thanks to that, the boiler achieves high effectiveness when heating by the individual fuels. The combustion gases exhaustion is handled by one outlet and therefore only one flue is needed.

• Possible combination of the individual types of fuel - fuels changing without modifications in the boiler wood + pellets, wood + natural gas, wood + extra LFOs
• Possible substitution of the individual burners - at any time, it is possible to choose a different medium
• High effectiveness in the individual fuels - for all practical purposes identical as in the special boilers for extra LFOs, natural gas, or pellets (up to 92.3% at the nominal output)
• Cheaper solution - adding the costs for the purchase of two boilers, their installation and smoking, we find that one boiler, though more expensive, is more economical.
• Less built-up area compared to a greater number of boilers
• One chimney and flue
• Ecological operation in all the versions of heating

The recommended installation is the connection of the boiler with Laddomat 21 or a thermoregulatory valve with a compensating tank with the volume of 500 to 1000 l. Another option is to install a boiler with accumulation tanks with the necessary volume (e.g. 2,000 l), which in addition enable the heating by accumulation electricity, or the connection of solar panels. If needed, the boilers may of course be also connected into the system without the accumulation tanks, especially if we choose natural gas (propane) or extra LFOs as the second medium.
The construction of Laddomat 21 replaces the classical installation of the individual parts. It consists of a cast iron body, thermoregulatory valve, pump, back flap, round valves, and thermometer. The thermoregulatory valve opens up at the temperature of 78 or 72 °C depending on the type of the thermo-cartridge.
