The BIODOM 21 pellet boiler is a smaller version of the popular BIODOM 27C5 pellet burner, designed for smaller private homes or buildings with a small technical space where every square metre counts. Nevertheless, the BIODOM 21 boiler is equipped with a high volume pellet tank and retains the same advantages as the rest of the BIODOM product range:

• Wide power output range, from 5.8 to 19.7 kW, with automatic start-stop function. Suitable for private houses with an area of 60 to 350m2 - also suitable for smaller private houses; 
• Automatic pellet quality detection, which ensures that combustion is adapted to the pellets used, improving operating efficiency and extending service life;
