    Added: 2018-06-29 | Category: boiler service | Comments: 0

    A full modulating fan automatically increases or decreases its speed according to the amount of gas coming into the boiler depending on the heat demand this process, called modulation, prevents the boiler from either having too little or too much air in the unit for optimal combustion - ensuring high efficiency. In addition, one has to make sure that the relevant service interval record section of the benchmark commissioning checklist has always been filled.
