More info

If needed, there is naturally the option to buy a boiler without a burner and select one later or to use a burner from the last boiler.


The boiler Atmos DC 25 SP 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.
