Pellet heating system - KWB Pelletfire Plus
The robust boiler for trade and industry
The KWB Pelletfire Plus pellet heating system is the ideal central heating for commercial buildings, housing developers and heat providers or heat contractors. It can be utilized in multi-boiler installations (cascades) and also be placed back to back to save space. In the output range of 45 - 135 kW, it is also used in multi-family houses and hotel facilities.
Safe and efficient heating
In the heat contracting business, operational reliability and calculable costs are decisive. For this reason, the KWB Pelletfire Plus pellet heating system has a burner system that is based on power-station technology. At its core is the KWB crawler burner which is manufactured according to industry standards. Made of high-alloy and self-cleaning cast grate elements, it functions like a type of “conveyor belt” for fuel. The fuel is always burned in a highly efficient and economical manner because, due to its continuous operation, the grate of the KWB crawler burner is able to automatically adjust to the output requirements. The ash does not contain any unburned residues, no fuel is wasted. The boiler detects how much fuel is needed and when. If there is no demand, it will not continue heating.
Easy ash removal
The optional two-part ash box, which can be easily unlocked and pulled out with its carrying handles, ensures even more convenience thanks to its integrated fill level monitoring. This makes it even easier to empty the individual ash containers because they are lighter. Thanks to the clean combustion and low fuel consumption, the ash box does not need to be emptied more than once every one to three months, depending on boiler size.
No cleaning required between service intervals
Because the KWB Pelletfire Plus pellet heating system is 100% self-cleaning during operation, your home stays warm. Even the heat exchanger cleans itself and removes its own ash. It also has special shaped turbulators to ensure that maximized heating energy is transferred from the exhaust to the heating system without compromising efficiency.
Easy and flexible control
The KWB Pelletfire Plus is equipped with the KWB Comfort 4 control system with the tried and tested dial and touchscreen display. This control system can be expanded in various ways. It is, for example, possible to activate different control units in the living quarters or operate additional heating circuits. An intelligent boiler master-and-slave circuit guarantees highly efficient operation thanks to the output modulation of multi-boiler systems based on actual demand. The free-of-charge KWB Comfort Online platform enables remote control and maintenance of the individual boilers! This is optionally also possible for the entire cascade.
cleanEfficiency technology
The KWB Pelletfire Plus pellet heating system comes with the cleanEfficiency label. This label stands for the lowest emission values, highest efficiency and economy, and the perfect interplay between construction and control elements.
- Safe and economical thanks to the unique crawler burner
- All-year maintenance-free thanks to the self-cleaning function
- Easy operation
- Particularly clean combustion
Advantages in detail
Easy installation thanks to a modular design
The KWB Pelletfire Plus pellet heating system can be disassembled into several modules which permits installation even in tight spaces with ceiling heights as low as 2 meters. It is therefore the ideal central heating system even for old buildings that are being redeveloped. This is impressively proven by the integration of a cascade with four boilers including buffer storage tank in the historical castle in the German town Langenselbold near Frankfurt/Main. The entire heating system was installed without a hitch.
Efficient exhaust gas recirculation
The optional exhaust gas recirculation is installed at the boiler’s exhaust gas connection. It takes a portion of the cooled down exhaust that is produced during combustion and recirculates it to the combustion chamber. This protects against wear even during continuous operation under peak load and cools the firebed at the grate thereby minimizing the fine dust production.
KWB Dust Filter E Plus
The KWB dust filter functions on the principle of electrostatic particle separation and removes the fine dust contained in the exhaust gas. The removed filter dust is collected in a generously-dimensioned ash tray which is conveniently and cleanly operated from the front. With the KWB dust filter EPlus, fine dust is no longer an issue, even with changing fuel qualities.
