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 Hydro Insert and in the heat
exchangers.
Therefore, please get your plumber's advice
concering:
• Hardness of water circulating in the system, to
prevent problems of incrustation and limescale,
especially in the domestic water heat exchanger
(>15° French).
• Installation of a water softener (if water hardness
> 15° French).
• Filling the system
(demineralised).
If you have very extensive system, with a large
amount of water, or which require frequent
refilling, it is recommended the installation of
water softening system. It 'should be noted that
the encrustations drastically reduce performance
because of their low thermal conductivity.
Pellet
The pellets are cylinders of compressed wood, produced from sawdust and wood processing (chips
and sawdust), generally produced by sawmills and carpenters. The binding capacity of the
lignin contained in wood, allows to obtain a compact product without adding additives
and foreign chemicals to the wood, is therefore obtained a natural fuel with high
yield.
The use of expired pellets or any other unsuitable material can damage
parts of the Hydro Insert and impair proper operation: this can lead
to the termination of the guarantee, and its producer responsibility.
For our products use pellets diameter 6 mm, length 30 mm and
a maximum of 8% and A1 certified according to the UNI EN ISO
17225-2 standard. Keep the pellets away from heat sources and not in humid environments
or with explosive atmosphere.
