Domestic hot water provision by storage charging
principle is an ecient so lution that fulls all hygienic
requirements. Hot water is stored at temperatures
that kill or prevent the growth of pathogens.
Favourable habitats for the proliferation of bacteria
such as legionella do not exist, provided the system
is operated in accordance with the instructions.
Ideally this requires an integrated circulation
management. When combined with optimally
hygienic stainless steel water tanks from our SE/SES
series, these systems are the ideal solution where
security of supply is of the essence, particularly at
peak load.
The system’s essential benets are:
• hygienically safe
• ecient cooling of the primary medium
• optimum use of energy
• free choice from a wide range of energy sources
• at all times sucient hot water temperature to
meet hygienic requirements
• constant hot water temperature
