Base for appropriate boiler selection is a thermal balance of the heated area created according to thermal standards for buildings. The nominal thermal efficiency should equal or be little higher (about 10%) than calculated heat requirement of the heated area. In the chart below No. 3 are information about size of area that can be heated by KWN-JETI boilers. Given data is approximate and was specified for rooms of 3m height.
Fuel recommended for KWNS-JETI boilers:
Light fuel oil, natural gas GZ 50, GZ 35
