See the relevant data table
- efficient and modern pellet heating.
SMARTFIRE EC 15 / EC 21
SmartFire EC is the third generation of modern pellet boilers, engineered to deliver high efficiency, environmentally friendly operation, and maximum user safety. Thanks to its modulating output and intelligent control system, the boiler automatically adjusts its operation to the current heat demand, reducing pellet consumption and delivering real energy savings.
The new SmartFire EC achieves up to 93% efficiency at its nominal output, delivering even higher performance than previous generations. The standard automatic heat exchanger cleaning system ensures reliable operation and maximum user convenience.
The key innovation of the SmartFire EC is its sealed combustion chamber, which allows combustion air to be supplied directly from outside the building. This ensures more stable combustion, improved efficiency, and enhanced operating safety.
SmartFire EC is an ideal solution for modern, energy-efficient buildings, including those equipped with mechanical ventilation systems.
