Hydronic reheat coils are a type of heating system that utilizes hot water to provide comfort in a building. The system works by taking water from a boiler and circulating it through a series of coils. The water is heated to a specific temperature, and then it is circulated back to the boiler to be reheated. The heated water is then circulated through the coils again, providing a steady and consistent source of heat. This type of system is often used in commercial buildings, as it is more efficient than traditional heating systems. It is also cost-effective, as it requires less energy to operate. Hydronic reheat coils are also beneficial for the environment, as they produce fewer emissions than other heating systems. Additionally, they are often quieter than other systems, making them ideal for buildings that require a quieter environment.
