The KWB Combifire logwood and pellet heating system combines the combustion systems for two fuel types in one efficient and optimized unified system with one shared heat exchanger. With a boiler output of 18 – 38 kW (logwood operation) and 22 – 35 kW (pellet operation), the KWB Combifire is suitable for all who love to get personally involved when heating with wood but also do not want to forgo the convenience of an automatic pellet heating system. It reliably supplies single-family and multi-family houses and agricultural businesses with heat. The daily ash removal is a thing of the past. The boiler can be ignited and controlled remotely.

KWB Comfort 4 Control System

Save on Fuel & Costs

The practical refilling display of the KWB Comfort 4 will always display how much log wood you need to add to efficiently operate your system! As soon as the door for refilling the logwood is opened, the pellet mod-ule will stop operating. The combination boiler automatically takes care of switching between fuels in an optimized manner, which saves fuel and thus costs!

Comfortable Consistent Heat

The setting request of the KWB Comfort 4 ensures that your log wood boiler will automatically ignite as soon as the system requires heat. The room and hot water temperatures you have specified will thus be continuously kept at the required level.

Heating with Highest Efficiency

An individual time program is highly convenient, particularly when you need to efficiently bridge the times when you are away from home. The KWB Comfort 4 ensures the optimal charging of the buffer storage tank both in log wood and in pellet operation.

Secure Remote-Controlled Heating

Even more convenience and operating safety is guaranteed by the online platform KWB Comfort Online. With this platform, the boiler can be easily remotely ignited, controlled and maintained from a smartphone, tablet or PC. Check on the operating status of your heating, control heating times and temperatures and receive messages and status changes via SMS or email. After a holiday, ignite the boiler while on your way home. If desired, you can also provide third parties with (temporary) individual access to your systems, such as your heating installer or KWB Customer Service.
