Popular boiler for fine coal
KMW from ZGM ZĘBIEC SA is an upper combustion heating unit which uses fine coal as fuel. If necessary, it will use hard coal or wood logs. The boiler is perfect for residential and utility buildings, commercial spaces and garages.
The large stoking door ensures easy replenishment of fuel, and the sizeable combustion chamber will hold fuel for at least 20 hours of heating. Such a duration of sustained burning is achieved by the use of a large enough combustion chamber, an efficient heat exchanger, and a controller which ensures steady burning.
The operation of the boiler is supervised by safety devices and sensors which react in due time and signal failures or threats. As standard, the KMW boiler is fitted with water and exhaust temperature sensors. All of these features contribute to thermal efficiency and safe operation of the unit.
Fine coal KMW boilers are efficient and popular heating units which work in thousands of Polish homes. This model features modern solutions which increase its heat efficiency. In the basic configuration, the unit is fitted with a fan blower and a controller, which maintains the temperature of the water in the boiler jacket. The multi-point air supply system ensures uniform and sustained burning, so the unit works longer and more efficiently, and the fuel does not need to be replenished frequently. The exchanger is made of certified boiler plates and insulated with mineral wool, which minimises heat loss even better.
