11 Hydronics Hydronics is a term that was introduced in the 1940s to refer to a system of heating or cooling of an internal area using fluids in either vapor or water form.

12 Hydronics These fluids are then circulated throughout a series of pipes or tubes to produce a desired room temperature.

13 Hydronics Although this official term was established in the 1940s, the process of using hydronics or "wet" materials to first heat, then later to cool, a home has been in existence for many years, beginning with the invention of cast iron boilers.
