WATER CHARACTERISTICS
The characteristics of the water used to fill 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 GET YOUR PLUMBER'S 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 plumbing bumpers to prevent banging along the fittings and pipes.
If you have very extensive systems, with a large amount of water, or which require frequent refilling, the installation of water softening
systems.
It should be remembered that incrustations drastically reduce performance due to low thermal conductivity.
