Thermal disinfection for preventing legionella infection causes:
− Excessively high return flow temperatures during the disinfection cycle (return flow tem-
perature limitation suspended)
− Excessively high DHW temperatures after thermal disinfection has been concluded
− Possibly lime scale, which can have a negative effect on heat exchanger performance.
