Fan coils are indoor climate control units for cooling and heating that are connected to a water circuit, serving as the system for transmitting thermal energy within the building's spaces. Their operation is based on the forced circulation of air created by the fan they have. With the help of the fan, heat is distributed in the space, in contrast to simple radiators that do this through convection without forced flow.

The main advantages of using fan coils compared to conventional radiators:

• In combination with a heat pump, we can achieve heating and cooling with a single system.
• Increased efficiency in heating and cooling, even at very low or high temperatures.
• The electricity consumption is minimal and proportional to the speed of the fans.
• Easy installation.
• Ability to achieve autonomy in each air-conditioned space with the use of a thermostat.
