Automatic efficiency
The Altep DUO UNI PELLET 21 boiler is a fully automatic heating device that can adapt to the conditions of residential buildings and industrial buildings of approximately 168 m². This boiler is capable of operating in heat maintenance mode with power modulation at 25% of the nominal, while providing a high efficiency of 91%. It is equipped with a 300 liter hopper with automatic pellet supply, which provides up to 60 hours of continuous burning and efficient heating without user intervention.
The flare-type burner installed in this boiler is highly economical, since it burns only the required amount of fuel. It is capable of automatically regulating itself based on data received from temperature sensors inside the heat exchanger, and can independently extinguish and rekindle. This burner also cleans automatically and does not require regular maintenance. When using high-quality pellets, virtually no ash is generated.
The manufacturer has provided the possibility of manual maintenance and loading of the boiler if it is necessary to use firewood, briquettes or coal for heating. The multi-channel air supply system optimizes the combustion process, ensuring maximum heat release.
Reliability matters most
The Altep DUO UNI PELLET 21 boiler is made of 6 mm thick steel and is designed for long-term operation without leaks or leaks. Double insulation of all technological hatches also ensures reliability and safety of operation. However, it is worth considering that the boiler weighs a significant 440 kg, so installation will require appropriate support. For more convenient control, you can install an optional Wi-Fi module for remote control.
