WATER CHARACTERISTICS
The characteristics of the water used to ll the system are very important to prevent the build-up of mineral salts and the formation of
incrustations along the pipes, in the boiler and in the heat exchangers.
Therefore, please ASK YOUR PLUMBER FOR HIS ADVICE CONCERNING:
• Hardness of water circulating in the system, to prevent problems of incrustation and limescale, especially in the
domestic water heat exchanger. (> 25° French).
• Installation of a water softener (if water hardness exceeds 25° French).
• Filling the system with treated water (demineralised).
• Possibly providing an anti-condensation circuit.
• Installation of hydraulic shock absorbers to prevent water hammering along the ttings and pipes.
If you have very extensive systems (with a large amount of water) or which require frequent relling, the installation of water softening
systems.
It should be remembered that incrustations drastically reduce performance due to their extremely low thermal
conductivity.
