The pellet boiler FLAT represents the latest compact boilers. The device goes with extensive equipment. Weather-compensated automatics with Lambda probe and HT-Logic III autocontrol ensures easy and simple operation. It is equipped with a burner with automatic cleaning, a system for automatic cleaning of the exchanger, a hydraulic module and a safety group.

The boiler structure 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 flue 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.

Operates in iPell R combustion optimisation standard 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 servo-motor, 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 a temperature sensor, it is adapted for fitting in a closed system in accordance with applicable legislation.

The design allows for convenient and user-friendly, hydraulic connections can be routed upwards or to the rear of the boiler, flue gas can be routed upwards, backwards or to the right side of the boiler
