|Comparing with floor heating, the fan coil system is essentially a completely water pipe system. Fan Coil Unit includes a fan and a coil which are used for heating and cooling and these units need a thermostat to be controlled.
If there is a single coil in the fan coil used, the system is called 2 pipes fan coil system. Two pipes circulate in the system making distribution and collection. A distribution pipe and a collection pipe are connected to each fan coil unit. In this case, either cold water or hot water can be circulated throughout the system.
