A hydronic system and method of use that will maintain normal system operating pressure while also reliably detecting even very small fluid losses in any closed loop fluid heat transfer system is described. The system includes a controller having clock or timing functionality in communication with one or more pressure sensors and a fluid supply valve that provides one or more notifications when the pressure drops below predetermined levels during predetermined periods of time. Depending on the nature of the pressure loss, the system has the capability of opening a fluid supply valve to provide make up fluid and increase system pressure.

A heating or a cooling system (102) comprising a fluid circuit (101) and apparatus (110) to supply a flow of top-up liquid to the fluid circuit (101). The apparatus (110) comprises a liquid reservoir (201) comprising an inlet port (202) connected to a liquid source (112), an outlet port (204) connected to the fluid circuit (101), and a pump (205) operable to move liquid from the liquid reservoir (201) to the outlet port (204) along a flow path. The apparatus (110) further comprises a light source (208) operable to emit ultraviolet light incident on liquid flowing from the liquid reservoir (201) to the outlet port (204) along the flow path. A method of supplying a flow of top-up liquid to the fluid circuit (101) of the heating or the cooling system (102).
