40. Requests for thermal disinfection
DVGW Code of Practice W 551 is the basis for carrying out the thermal disinfection.
The thermal disinfection should cover the entire system including all extraction taps.
All wetted interior surfaces of a drinking water installation system (e.g. shower head
material temperature) must be heated to at least 70 °C for more than 3 minutes.
The water in the water heater must therefore be heated to 85 °C.
The outlet temperature (properly speaking, the surface temperature) must be
checked at each extraction point.
All the extraction points must be closed during the heating phase of the water heater,
so that the complete system (hot water and circulation line) is covered by this
measure in circulation systems. The circulation pump must be run in continuous
operation. This operating state is maintained until a temperature of >
70°C is
reached in the circulation water.
Only then are the extraction points flushed in turn with the outlet open.
The thermal disinfection must be carried out section by section depending on the
size of the installation and the pipe run. The individual sections must be thermally
disinfected in direct succession, in order to exclude recontamination of the
installation.
The thermal disinfection may have to be interrupted until the water has been heated
up again by the water heater.
The installation must be returned to normal operation after thermal disinfection has
been completed. In this respect, each tap must be actuated, in order to drain hot
water (> 43 °C).
Warning!
Personal protective measures (scald protection) must be implemented for the
duration of the thermal disinfection. This might include cordoning off the shower
facilities.
Failure to observe this instruction can result in injuries due to scalding.
The operator is responsible for the execution, monitoring, and logging
(room, tapping point, date, time, temperature and duration).
The manufacturer does not accept any liability for claims by third parties relating to
the improper execution of thermal disinfection on the part of the operator.
