Thermal disinfection
CAUTION:
Risk of scalding.
During thermal disinfection, discharging unmixed hot water can
cause serious scalding.
▶ Only use the maximum adjustable hot water temperature
for thermal disinfection.
▶ Inform occupants of the premises of the risk of scalding.
▶ Perform thermal disinfection outside of the normal
operating times.
▶ Do not discharge DHW unmixed.
▶ Ensure a thermal mixing valve is fitted as stated in the UK
G3 building regulations.
Perform thermal disinfection/daily heat-up to kill off pathogens
(e.g. legionella) on a regular basis.
To guarantee thermal disinfection/daily heat-up:
▶ Set the heat source (e.g. boiler) in such a way that daily
heat-up can be carried out, for example temperature
settings or time programme for DHW heating.
▶ Install the pipework for system components, which are
necessary for thermal disinfection or daily heat-up, as
energy-efficiently as possible (short pipe lengths, good
thermal insulation, etc.).
In the case of larger DHW systems, there may be statutory
requirements (
regulations on drinking water) for thermal
disinfection. Observe the instructions in the technical
documentation of the heat source.
