Required cleaning intervals are different depending on the water quality and the
temperature of the storage tank. A yearly interval is recommended.
IMPORTANT: With a drinking water hardness of over 20° dH, a yearly cleaning interval
is a requirement for asserting any warranty claims.
The cleaning is done through the flange aperture. The enamelled internal surface prevents
limestone formation as far as possible and allows for a quick cleaning of loose lime
deposits by means of a sharp water jet. Incrustations may only be crushed with a wooden
stick before the flushing out. Sharp and/or metal objects may not be used for cleaning as
there is the risk of damaging the tank or the enamel.
The DHW heat exchanger in fresh-water storage tanks is cleaned by flushing it with a
suitable descaling agent (e.g. citric acid).
IMPORTANT: After the cleaning, the connections have to be checked for tightness again
before and after the reheating and they have to be retightened if necessary. We assume
no liability for damages caused by water.
