Filling the installation
6.8.1
Water treatment
In many cases, the boiler and central heating system can be filled with
normal tap water and water treatment will not be necessary.
Warning
Do not add chemical agents to the central heating water without
consulting Remeha. For example: antifreeze, water softeners, pH-
increasing or lowering agents, chemical additives and/or inhibitors.
Such agents can cause errors in the boiler and damage to the
heat exchanger.
Important
For untreated water, the pH value of the water in the installation
must be between 7 and 9 and for treated water between 7 and
8.5.
The maximum hardness of the water in the installation must be
between 0.5 and 20.0 °dH (dependent on the total heat output
generated).
More information is available in our Water quality regulations.
Always adhere to the instructions in the aforementioned docu
ment.
