Types & Applications of Hydronic HVAC Systems

Radiant Heating and Cooling Systems

Radiant systems circulate heated or cooled water through tubing embedded in floors, walls, or ceilings. This method provides uniform temperature distribution and eliminates air drafts, making it ideal for residential homes, offices, and healthcare facilities. Radiant floor heating, in particular, is popular in colder climates due to its high efficiency and comfort.

Fan Coil Units (FCUs)

FCUs consist of a heat exchanger (coil) and a fan. Chilled or heated water is circulated through the coils, and air is blown over the coils into the room. These systems are commonly used in hotels, commercial office spaces, and apartment complexes due to their compact size, zone-based control, and ease of installation.

Chilled Beam Systems

Chilled beams are ceiling-mounted convection HVAC systems that use chilled water to cool indoor air. Passive and active variants are available, offering high energy efficiency and low noise. These systems are widely used in modern office buildings, educational institutions, and laboratories that require precise temperature control and low operational noise.
