Thermal Circulation (TCV) for Public Health

TCVs provide self-balancing, thermostatically controlled regulation of flow and thermal disinfection, assisting with protection against Legionella. The valves automatically adjust in response to changes in fluid temperature to ensure that stable temperatures are maintained across domestic hot water systems.

There are legal requirements for designers and installers to consider the risk of Legionella.
