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 the phenomenon known as “water hammer” from occurring
along the fittings and pipes.
For those who have very extensive systems (with large amounts of water) or which require frequent refilling, to install water softening
systems.
It should be remembered that incrustations drastically reduce performance due to low thermal conductivity.
