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;
• Automated self-cleaning of the pellet burner, which makes the operation of the pellet boiler much easier and also cleaner - no need to spend time periodically cleaning the ash from the pellet boiler;
• Durable cast iron pellet burner;
• High energy efficiency - up to 92%;
• Built-in safety group and circulation pump, which reduces the heating circuit visible outside the boiler and helps to take up less space in the boiler room overall;
• Automatic start-up - Plug and Play system, which makes the pellet boiler almost completely self-contained (periodic pellet filling and ashtray cleaning required);
• The pellet tank contains enough pellets for ~ a week of operation - even in the compact BIODOM 21 version, the pellet boiler is equipped with a spacious 130 kg pellet tank, capable of ensuring a long operating period between refills;
• Hot water production and operation in hybrid heating mode;
• Warranty: 2 years for the electronics, 5 years for the boiler housing;
