Cortena Series

All-In-One Pellet Boilers

“Compact and Convenient Heating Solutions”

The Cortena Series is designed to fit homes with limited space, offering a true plug-and-play solution. These boilers include all the necessary features of a boiler room in a compact unit: a built-in circulation pump, expansion tank, plumbing, modular burner, and an optional plate heat exchanger. This design ensures minimal space occupation in your boiler room.

With a 100-liter fuel tank, the Cortena Series enables prolonged operation times. An integrated auto-cleaning system for the modular burner eliminates the need to open the boiler for cleaning and restarting, enhancing both comfort and efficiency.

Cortena boilers are equipped with top-of-the-line safety measures. Pressure discharge valves prevent damage from unexpected pressure increases in the combustion chamber, while child-locks secure all child-accessible doors. An observation glass allows you to check the operation and interior of the combustion chamber.

Maintenance is made easy with the Cortena Series. The modular burner, a feature often found in larger boilers, can be removed and maintained outside the unit, increasing operation time and reducing maintenance effort.
