Fan coil units operate using hot or chilled water supplied by a heat pump or another hydronic heat source, whereas conventional air conditioners use a direct refrigeration cycle with refrigerant circulating between indoor and outdoor units. Fan coil systems provide both heating and cooling as part of a comprehensive hydronic installation, making them an ideal solution for buildings with central heating and cooling systems. They can also be seamlessly integrated with underfloor heating, smart controls, and Building Management Systems (BMS), delivering greater energy efficiency, enhanced comfort, and flexible year-round climate control.<\/p> <\/div>\n\n <\/div>\n\n <\/div>\n\n \n
