What does Hydronic Heating and Cooling refer to?

Hydronic Heating and Cooling refers to the method of heating and cooling spaces using water as the primary medium. This system utilizes the principles of heat transfer, where water is heated or cooled and then circulated through pipes to radiators or heating coils throughout a building. When the water is heated, it releases heat into the air, warming the living space, and when it's cooled, it can absorb heat from the air, thereby cooling the space.

Option B accurately encompasses the essence of hydronic systems, which can involve the forced circulation of liquids (water or other fluids) to manage indoor temperatures effectively. These systems can be designed to work in both heating and cooling modes, which is a key characteristic of their versatility and effectiveness.

Understanding the hydronic principle is crucial in HVAC design, as it allows for efficient thermal management using water—a central aspect within the definition of hydronics.
