Hotwater cylinder/Calorifier blow down, descaling and disinfection

An internal visual check for scale and sediment in the cistern must be carried out on an annual basis or where the water quality seems to be cloudy. The sedimentation, scale etc. will settle down in the calorifiers and will provide an environment for Legionella growth, therefore the cleaning and disinfection of this storage vessel must be carried out. If there is no inspection hatch available, the system must be flushed thoroughly on regular intervals to avoid the formation of scale and debris in the base of the storage vessel.

For calorifiers with no access hatch a sample of drain water should be taken and its condition noted.
