High output in a compact space

Thanks to its compact design, the KWB Classicfire 1 is ideally suited to small boiler rooms. Combined with a buffer storage tank with a capacity of just 1,000 litres, it requires particularly little space. Its low overall height and low flue pipe connection also make the log wood boiler an ideal solution for renovation projects, as it can be installed easily in older boiler rooms with a low chimney connection.

Convenient and efficient

The KWB Classicfire 1 log wood heating system is filled conveniently in the traditional way using logs up to 50 cm long. The generously sized front door makes loading easier and ensures a high level of operating convenience. Thanks to the 80-litre filling chamber, the boiler generally only needs to be loaded once or twice a day to supply an average single-family home with heat throughout the day.

The KWB Classicfire 1 is equipped with a speed-controlled induced draught fan, ensuring particularly efficient combustion. The fan is positioned at the flue pipe connection and draws air through the boiler. The greater the airflow, the higher the output.

The control system automatically detects whether sufficient heat is already available in the system, for example when the temperature in the buffer storage tank is high enough. In this case, the speed of the induced draught fan is reduced and the boiler output is lowered to as little as 50%. This saves fuel and money.

For log wood operation, the ash container is not permanently attached to the boiler and can be stored underneath it to save space. When required, it can simply be hooked directly beneath the loading door. A cleaning set with sweeping tools is supplied as standard with the KWB Classicfire 1.

Easy and flexible operation

The KWB Classicfire 1 can be operated using the KWB Comfort 4 control system via the colour touchscreen display or alternatively with the control dial. The dial is particularly practical when wearing work gloves, for example while adding more wood.

The intelligent control system makes heating even easier by indicating, among other things, how much wood should be added for optimum operation. It is also prepared for connection to the KWB ComfortOnline platform, allowing the boiler to be controlled and maintained remotely using a smartphone, tablet or PC.
