KWN JETI boiler
KWN-JETI boilers are designed for heating single-family houses as well as big housing developments. Fuels used in that type of boilers are: gas fuel and liquid fuels used in heating.
KWN-JETI heating boilers have certification of compliance with energy efficiency criterion.
mission and energy tests were conducted by:
– Institute of Heating and Sanitary Technology in £ód¼.
KWN-JETI heating boilers are designed to heat water in the open central heating systems according to PN-91/B-02413 to the temperature not exceeding 900 °C at the boiler’s outlet. KWMS heating boilers are designed for heating living quarters, warehouses, commercial halls, workshops, farm buildings, glasshouses, schools etc. They can work in gravitational or induced systems.
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.
