At this temperature the bacteria cannot survive for over 20 minutes. It is recommended that these heating
procedures be done at night, when it is more likely that the hot water tank is at a higher temperature and
when no DHW is consumed, thereby reducing the power input needed.
During normal operation, the electric heater cannot be activated for other purposes than legionella
protection; that is, the electric heater is never used for DHW production, or to support the heating system.
FAULT mode
In the event of a possible failure of the heat pump that does not allow the compressor to start up, the electric
heater may be activated to produce DHW. This guarantees DHW poduction if the heat pump fails.
