ThermoFLUX Interio 18 pellet boiler with 42kg pellet hopper, 0001257
ThermoFLUX Interio 18 is a compact pellet boiler designed for installations where available space is limited. The boiler requires only approximately 1 m² of installation space, making it suitable for small utility rooms and boiler rooms.
Interio 18 is equipped with a cast-iron pellet burner designed to provide complete pellet combustion and reliable ignition. A circulation pump, expansion vessel and safety valve are integrated into the boiler, simplifying the installation of the heating system.
The integrated tubular heat-exchanger cleaning system makes regular cleaning and maintenance easier.
The digital control system continuously monitors the combustion process and adapts boiler operation to actual conditions. As the set temperature is approached, automatic regulation reduces boiler output and pellet feed, helping reduce pellet consumption and optimise flue-gas emissions.
A room thermostat or WiFi module can be connected for additional monitoring and remote control. The control system also supports automatic regulation with weekly programming.
