Description

SMARTFIRE COMBI 20/26

SmartFire Combi is a modern hybrid boiler for wood and pellets, combining comfort, flexibility and freedom in fuel selection. After loading the wood, the boiler automatically detects the fuel change, ignites the wood charge and, once it has burned out, automatically switches back to pellet operation.

As standard, the boiler is equipped with a cooling coil that increases safety and simplifies installation. Large doors and a spacious combustion chamber make it easier to load even larger logs. A cast-iron safety flap protects the pellet hopper against flame backburn.

Automatic heat exchanger cleaning helps maintain high efficiency over time. The automatic ash removal system with ash compression reduces the frequency of emptying the ash container to as little as 1-2 times per heating season. The pellet burner with a moving grate automatically removes ash and deposits, ensuring stable operation even when using lower-quality pellets.

Operation is managed by a weather-compensated controller for convenient adjustment of the heating system. SmartFire Combi meets the requirements of Class 5 and Ecodesign.
