Technology that has been tried and tested for years, optimized in an environmentally friendly way; the BK full condensing boilers from Kroll. Whether for heating new buildings or modernizations, for your own home or large industrial complexes; with a full condensing boiler from Kroll, you not only heat particularly energy-efficiently and economicallybut also comfortably. With a wide range of outputs between 15 and 500 kW the right model is available for a wide variety of needs; even a cascade connection with up to 2.000 kW is possible. Conventional condensing boilers allow hot flue gases to escape unused via the chimney if the temperature is too high. Our fully condensing boilers use the heat contained in the flue gases independently of the return temperature and convert it into additional heating. This not only saves you energy and costs, but also provides particularly environmentally friendlyheating. The special boiler design allows the flue gases in the boiler body to be cooled down to approx. 80°C. In a downstream plastic heat exchanger, the remaining heat is extracted from the flue gas and used to preheat the combustion air. Unlike other condensing boilers, our BK operates permanently and without restrictions in the full condensing range. In concrete terms, this means that the flue gas temperature is a maximum of 47°C in any operating state. Through full condensing operation, we realize a significant increase in efficiency and thus reduce your operating costs. Permanent condensing function - independent of the return temperature Exhaust gas temperature with oil max. 47°C / with gas max. 57°C Operation with fuel oil or natural gas
