Annual cleaning prevents bacteria in hot water tanks

To achieve good hygiene in the water installation, it is important that the hot water tank is opened and cleaned once a year. Not only to avoid corrosion - but also to prevent bacteria in the water system.

  • Mechanical boiler cleaning
  • Disinfection with chlorine dioxide
  • Prevent bacterial growth (e.g. Legionella)
  • Protects against corrosion

At boiler cleaning a mechanical cleaning of the container surfaces is carried out. However, a boiler cleaning does not completely remove the biosolids that inevitably settle on the inside of the tubes.

The combination of a tank cleaning and a disinfection provides an effective prevention of bacterial growth in the tank - such as Legionella. And when this is done at the same time, costs are low.

Why boiler cleaning?

In the hot water tank (see Hot water tank), impurities are deposited as sludge over time and a layer of lime and bioslim (biofilm) is formed on the inside and on the heating element. It may therefore be appropriate to clean the inside of the hot water cylinder on a regular basis.

If the hot water installation is protected against corrosion by means of an electrolysisor Katolyse® system with an associated service agreement, the cleaning is covered by the agreement. However, the need will also be present for boilers without corrosion protection.

Change of anodes

If your system is fitted with anodes, these must be replaced when they are about to run out. If you have a service contract, we will contact you approximately 3 weeks before the electrode replacement is due to take place.

03.

Prevent legionella bacteria

EWGLI (European Legionella Working Group) recommends annual cleaning of hot water tanks for biofilm and bacteria.

Container disinfection

The NEW Piping Center Instruction 017 describes boiler disinfection with chlorine dioxide as the best method to prevent Legionella bacteria in the installation.
