Hydronics refers specifically to the use of water as a medium for transferring heat in heating and cooling systems. This method leverages the high heat capacity of water, allowing it to effectively transport thermal energy throughout a building, whether for heating or cooling purposes. The concept is fundamental to many heating systems, like radiators and underfloor heating setups, where water circulates through pipes to either deliver heat to a space or remove it based on the requirements of the environment. In contrast, other mediums such as oil, steam, or air are not representative of hydronics. For example, while oil and steam can also be used as heat transfer mediums, they fall outside the scope of hydronic systems specifically designed around water. Air, on the other hand, is utilized in HVAC systems but does not align with the definition of hydronics since it does not involve water as the transfer medium.
