Does tado° support Legionnaires' disease protection on my heating system?

Legionnaires’ disease is a type of lung infection that can be acquired by the inhalation of contaminated water. The infection is caused by Legionella bacteria.

Legionella develop in water stored at a temperature ranging from 20 °C to 50 °C. To avoid the risks of legionella development in a domestic hot water tank a setpoint temperature of above 60 °C should be set.

Alternatively, the development of the bacteria can be controlled by regularly raising the water temperature above 60 °C to destroy the bacteria.

Most boilers connected to a domestic hot water system are equipped with anti-Legionella provisions. These remain unaffected when installing tado°. In some rare cases the controller that activates Legionella disinfection is replaced by tado°. In these cases the same feature is activated on tado°.

If you have any questions regarding Legionella disinfection for your heating system, please contact our technical support.
