What does hydronics refer to?

Hydronics refers to the science of heat transfer using water. It involves the use of water as a medium to transfer heat for heating and cooling applications in buildings. Hydronic systems often include components such as boilers, pumps, pipes, and radiators, which work together to provide efficient heating or cooling through the circulation of water. The focus on water as a heat transfer medium is what distinguishes hydronics from other systems, highlighting its effectiveness in maintaining comfortable indoor temperatures and its application in radiant heating and cooling systems.
