Heating hot water systems typically supply which of the following?

Heating hot water systems are primarily designed to produce and distribute hot water for various applications, particularly in heating processes. In this context, hot water coils in air handling units are specifically utilized to provide heating for air that is circulated throughout a building. The coils transfer heat from the hot water to the air, effectively warming it before it is distributed into the occupied spaces.

This application is crucial in maintaining comfortable indoor temperatures, especially during colder months. Hot water coils in air handling units demonstrate the direct connection between hot water systems and climate control in buildings, making them a key component of a heating, ventilation, and air conditioning (HVAC) system.

While cold water storage tanks, floor heating systems, and drainage systems have their own roles in plumbing and building systems, they do not directly relate to the function of a heating hot water system in the context of providing heated air through coils. Cold water storage deals with the storage of freshwater, floor heating systems utilize different methods for heating, and drainage systems are related to waste removal rather than heating applications.
