The traditional wood-gasifier boiler The KWB Classicfire log wood boiler is the ideal central heating system for agricultural and forestry businesses, as well as single- and multi-family house owners that own a forest or have access to wood. It is available in the output range of between 18 and 38 kW and scores points particularly due to its convenient operation. Convenient and efficient heating It is, for example, possible to easily fill the KWB Classicfire log wood heating system the traditional way with wood logs of up to half a meter length. The large-sized front door ensures a high comfort level during stoking. Thanks to the 185-litre fuel fill room, the boiler generally only needs to be stoked once a day to heat an average single-family house for a whole day. Here, constant stoking is a thing of the past. Easy and flexible operation The KWB Classicfire can be operated using the Comfort 4 control system via the colour touchscreen display or alternatively via a dial. The use of the dial is particularly recommended when operating the control with work gloves, right after stoking the boiler with wood. But the intelligent control system makes heating even easier. The Comfort 4 system indicates, for example, how much wood you should refill for optimal operation. The control is also set up for the use of KWB Comfort Online. Using this platform, the boiler can be easily controlled and maintained remotely via smartphone, tablet or PC. Easily upgrade to a combi-heating system The KWB Classicfire log wood boiler can be easily upgraded with a pellet module that is installed on its left side. Upon request, a log wood heating system can thus be turned into the KWB Combifire combination heating system for log wood and pellets. The central heating’s ability to switch between the two fuels is fully automated. If the log wood is running out, the boiler simply switches to heating with pellets.
