This is because the bacteria multiply where temperatures are between 20-45°C. The bacteria remain dormant below 20°C and do not survive above 60°C.

With the right smart thermostat technology incorporated into modern unvented water-heating systems, the solution to the ‘new normal’ is easily achieved.
