A hydronic fan coil unit (FCU) is a piece of HVAC equipment designed to heat or cool a space using...

Radiant heating operates through the transfer of thermal energy via electromagnetic waves, distinguishing it as one of the three primary heat transfer methods alongside conduction and convection. Unlike conduction, which requires direct contact between objects, or convection, which relies on the movement of fluids or gases, radiant heating transfers energy through empty space.
