5th class pellet boiler

The DasPell NEXT BASIC pellet boiler is one of the latest compact boilers. Weather-compensated automatics with Lambda probe and HT-Logic III autoregulation ensures easy and simple operation. It is equipped with a burner with automatic cleaning, a system for mechanical, manual cleaning of the exchanger and a return protection pump.

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 chimney draught.

The boiler and the heating system are controlled by HT – Tronic 900 weather-compensated controller which 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 autocontrols 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 protected by a return protection pump with temperature sensor. It is suitable for fitting in a closed system in accordance with applicable legislation. Its structure makes boiler fitting easy and user-friendly. The flue gas is led out through an exhaust fan that can be set in 5 positions from the horizontal position (angle 00, 450, 900, 1350, 1800).
