PRODUCT OVERVIEW

KWB MULTIFIRE

Robust & Economical Heating

  • Flexible fuel selection thanks to the unique crawler burner
  • Particularly efficient in operation
  • Easier handling due to a divided ash box

The KWB Multifire, a high-quality biomass boiler, is lauded for its robustness and fuel efficiency. This biomass boiler automatically adjusts to the fuel's quality or features, making it a reliable choice. With an output range between 20 - 120 kW, it serves as the perfect central heating solution for multi-family houses, agricultural settings, and commercial businesses. Additionally, the optional divided ash box with integrated fill level monitoring ensures maximum convenience for the user.

 

Robust Crawler Burner

With high-alloy and self-cleaning cast grate components, it enables the use of varying fuel qualities. This makes you even more flexible when heating with wood chips or pellets.

Easy Operation

Easy & Flexible Control

The KWB Comfort 4 control system offers dual operation options with an intuitive dial and colour touchscreen. It provides information on:

  • the ash fill level
  • the storage room fill level
  • the maintenance interval

In addition, a solar system can be integrated and is also prepared for a link to the KWB Comfort Online platform.

Online Control

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 individual (temporary) access to your systems, such as your heating installer or KWB Customer Service.

Heating Networks

Perfect Buffer & Cascade Management

The heating system is optimally equipped for the supply of heating networks. With control modules, the desired values of the transfer sites can be transferred to the central main control using the bus system without the need for an external switch cabinet. The entire system can be monitored and controlled remotely with the KWB Comfort Online platform.

Due to the desired fail-safety, heating networks are often supplied by a multi-boiler system. This cascade may consist of several KWB biomass heating systems, but can also contain external boilers. A runtime-optimized control of up to 8 KWB biomass heating systems plus additional external peak load boiler is possible with the new output-modulating KWB Boiler sequence control. Activation occurs infinitely modulating. This results in an efficiency increase of the entire system with reduced emission values.

In addition, a seasonal operating mode and the integration of the boilers in the building control system via a ModBus interface is possible.
