Legionellae bacteria are micro-organisms that can cause serious diseases of the respiratory tract. Legionellae remain in a latent state in cold water (below 20°C) and can proliferate in warm water (from 20°C up to 45°C). They can be eliminated (in a few hours), however, at temperatures higher than 50°C – or in a few minutes above 60°C. It is recommended never to store the hot water thereafter at a temperature below 60°C.
The “Tank-in-Tank" system prevents the formation of warm pockets because even the base of the inner tank is a heat exchanger that remains at the temperature of the boiler (typically from 60 to 80°C): thus, any “Tank-in-Tank" water heater operating at 60°C ensures that the hot water remains free of legionellae and safe for the consumer.
