Product Portfolio
PELLET HEATING SYSTEMS
- Comfortable and automatic heating with pellets
KWB pellet heating systems are modern and efficient central heating systems that mainly run on climate-neutral wood-pellets. The work fully automatically. KWB heating systems come with different varieties of filling chambers.
Advantages of a pellet-heating system
Pellet heating systems are just as user-friendly as central heating systems fired with oil or gas. However, they cause the lowest fuel costs as well as the lowest carbon emissions when it comes to central heatings.
Heating comfortably with pellets
Heating with KWB is quintessentially comfortable: At a capacity range of 135 kW KWB pellet heating systems come with a wheeled ashes container. Up to 15 kW there is almost no cleaning effort as the ashes container only has be emptied every two years.
At a high capacity range we separately offer large ahes container in order to be able to guarantee an easy operation.
Thanks to the dual control system consisting of a dial and a touchscreen display the heating can intuitively be operated. Combined with the KWB Comfort Online platform it can also be controlled remotely.
Cheaper than oil and gas
As pellets are made of a renewable commodity and as the pellet market works independantly from the political international situation heating with pellets is significantly cheaper than heating by oil or burning gas. All KWB wood-fired heatings are government-funded.
Ecofriendly pellets
Pellets mainly consist of sawdust which means that no tree has to be cut to the ground for producing them. As wood regrows our customers are virtually heating in a climate-neutral way.
Modern wood-pellet heating systems are extremely clean. They meat meet even the most stringent restrictions in Germany and Austria.

WOOD CHIP BOILERS
- Heating with woodchips: Inexpensive and flexible
Your benefits
Wood chip fired heating systems are truly economic solutions as wood chip is a regional product. Therefore, it is inexpensive. Still, fluctuating fuel qulities are a challenge for a wood chip fired boiler.
Just to make sure
Reliability is a central quality attribute when it comes to our wood chip fired boilers. That is why our KWB wood chip fired boilers do not only consist of robust components but also:- The main burner parts are casted and consist of self-cleaning components. The concept stems from large biomass combined heat and power stations.
- We offer some comprehensive service- and maintenance packages.
We offer different kinds of storage room systems that fit the individual requirements of a wood-chip fired heating. Everything will be planned individually. We also support you when it comes to the different possibilities for grants in order to help you reduce the investment costs. KWB MULTIFIRE

WOOD-FIRED BOILERS LOGS & PELLET BOILERS
- Enjoy full indipendence
The advantages of a firewood heating
Our log wood fired boilers and combination boilers guarantee for independence. Wood is a local fuel. The delivery channels are short. On top of that you will get the highest state funding for a combination boiler. If you decide to combine the boiler with a solar array you can get up to 10.000 euros and more from the state.
KWB log wood fired boilers: particularly comfortable
Our carburetors for log wood are totally easy to operate. The KWB Classicfire has a 180 litre filling chamber, the largest of its class, that ensures long refill intervals. On top of that the boiler indicates on the control display how much firewood you should refill.
No compromises: The pellet module
You want to heat fully automatically for example when you are on vacation so as to be able return to a cosy and warm home? If yes, you will be interested in the optional pellet modul. Thanks to our ComfortOnline system you can start the heating remotely.
The pellet burner stems from our KWB Easyfire pellet heating which has been tested a ten tousand times. Thanks to the efficient comustion you only have to empty the moveable ashes container after the heating has consumed six tons of pellets.
Ideally combined with a buffer storage tank
Log wood fired heatings will be combined with buffer storage tanks. In that way they work even more efficiently. KWB offers premium storage technology. In that way your heating is prepared for for supplements: The thermal solar array. The collectors of our solar array stem from the global leader greenone TEC.

SYSTEM ACCESSORIES
- Your complete energy system from a single sourceK
WB is not only a specialist when it comes to heating with renewable energy but also has a profound know-how when it comes to individual storage room solutions, efficient storage systems and intelligent control technology. 
Storage technology
- The right storage ensures that your heating becomes an
energy central: The storage takes the warmth from the heat generator and
distributes it based on demand.
There are boilers, buffer storages and stratified tanks. Hot water storages contain heated raw water. Buffer storages provide heat for raw water and heating. Stratified tanks are special buffer tanks that store warm water in different layers depending on its temperature which is highly efficient. KWB storages are also avialable combined with a solar contactregister so that a solar-thermal plant can be incorporated.
With pellet heatings, heat pumps and woodchip boilers we recommend installing a buffer storage. If you heat with solarthermics and/or wood firewood it is necessary to install a buffer storage.
Advantages of a KWB storage room system?- Reliability
KWB offers particularly low maintenance storage room systems. - Comfort
Fuel storage: Long refilling intervals as the available space gets optimally used. - Efficiency
The sorage room concept protects the pellets, minimizes the dust and maximizes the efficiency of your wood fired heating.

Storage room technique and fuel transportation system
- Planning example of a KWB PelletfirePlus pellet heating
system including a pellet stirrer and a suction conveyance.
Since KWB has developed automatic wood fired heating systems our engineers concentrate on save, comfortable and low-maintenance storage room solutions.
The patented KWB Pellet Stirrer Plus is one of our unique features: A ground low fuel transport system that allows for optimal space utilisation including a heavy-duty gear.
Our goal is to find the right storage room solution for your individual structural requirements. The fuel gets transported via KWB seduction conveyance (pellets only), a screw or a stirrer. Upon request we also plan your special solution (e.g.: drop shaft, push floor).
