The BIODOM 21M specialised pellet boiler is suitable for small boiler rooms or smaller private homes, while retaining the high-capacity integrated pellet tank (130kg). 

Although comparable in design to the simpler BIODOM 21 pellet boiler, it operates more efficiently and with an even higher level of automation, thanks to the included intelligent control unit, which allows not only remote control of the pellet boiler, but also control of multiple heating circuits, hot water preparation or additional connections - storage tank, solar collector or heat pump. This simplifies the control of the overall heating system and the pellet boiler.

The main advantages of the product are:

• High power modulation (from 5.8 to 19.7 kW) - Automatic start-stop function. Thanks to the wide power range, the pellet boiler can be adapted to different sizes of private houses or its power can be changed, e.g. in the case of insulation or extensions;
• Continuous pellet quality detection, allowing the pellet boiler to adapt to certain pellets, burn them as efficiently as possible and prolong their working life in the long term;
• Continuous monitoring of the pellet combustion process to ensure safe operation of the plant even when you are not at home and to make sure that the pellets burn as efficiently as possible;
• Durable cast iron pellet burner;
• High energy efficiency - up to 92%;
• Automatic start-up - Plug and Play system, which makes the pellet boiler almost completely self-contained (periodic pellet refilling and ashtray cleaning required);
• Hot water production and operation in hybrid heating mode with a connected heat pump or solar collector;
• Remote control;
• Warranty: 2 years for the electronics, 5 years for the boiler housing;
• Manufacturer: Slovenia.

Energy efficiency class: A+
