Pellet boiler ONE is a modern compact boiler with small dimensions and extensive equipment. Weather automatics with Lambda probe and HT-Logic III autocontrol for smooth and user-friendly operation. It is equipped with a burner with automatic cleaning, a system for automatic cleaning of the exchanger, including a hydraulic module and a safety group.

The boiler construction is based on a vertical flame tube heat exchanger with an automatic exchanger cleaning system. Burning is performed by a self-cleaning, automatic drop-in burner with an openable floor, equipped with an igniter, a photoelement and a thermocouple. The boiler is equipped with an exhaust fan which aerates the combustion process and improves the chimney draught.

The boiler and the heating system are controlled via a 5″ touch screen, made in capacitive technology. Weather controller HT-tronic 900 Touch controls the operation of 4 pumps and a mixing valve actuator. The automatics can be expanded by connecting additional modules. The controller is compatible with a remote control panel, 2 room thermostats and an internet module. It is equipped with HT-Logic III autocontrol which controls the operation of the burner, selects the operating parameters and modulates power depending on the boiler temperature.

It works with the standardiPell R combustion optimisation with HT-tronic Lambda module. The optimisation system with a probe guarantees the highest combustion quality.

The boiler is equipped with a hydraulic module, which consists of: mixing valve with accentuator, valve pump, DHW pump and safety group in a form of diaphragm vessel, safety valve and manometer. The boiler is protected by a return protection pump with temperature sensor. It is suitable for fitting in a closed system in accordance with applicable legislation.

Boiler ONE 8 is awarded GOLD MEDAL of at the Instalacje Fair in Poznań.
