Hot Water Coil
How Hot Water, Boosters and Reheat Coils Work
In some regions, you may encounter radiant heat or baseboard heating systems, which differ in their operation. Unlike hot water coils, these systems do not involve air passing through them; instead, they emit heat that warms the surrounding air. Hot water coils, however, are integrated into forced air systems, while booster coils or reheat coils are employed in downstream ductwork to reheat air that has cooled off
Hot Water Coil Components Explained
Hot water coils represent one of the fundamental components in an HVAC system. Understanding their components is crucial for determining the necessary connections and their proper placement. Similar to chilled water coils, if a leak occurs in a hot water coil, it typically manifests in the copper u-bends. However, due to the presence of hot, high-pressure water, the initial point of leakage may occur at the weakest point, which could be a return bend or somewhere in the middle of the coil. Repairing a leak in the middle of the coil can significantly compromise its efficiency.
Regardless of the apparent simplicity of a hot water coil or reheat coil, you still have various material options to consider
