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 relling, the installation of water softening

systems.

It should be remembered that incrustations drastically reduce performance due to their extremely low thermal

conductivity.
