Protecting the installation against scaling
Additional precautions are required to protect the installation:
• If a softener is installed, the equipment must be checked in accordance with the manufacturer's
recommendations to ensure that it is not discharging chloride-rich water into the network: the chloride
concentration must always remain below 50 mg/litre.
• If the water in the network does not have the desired qualities (e.g. high hardness), treatment is required.
This treatment must be carried out for the filling water as well as any subsequent refilling or topping up.
Periodic monitoring of water quality in accordance with the water treatment supplier's recommendations
is required.
• To avoid the build-up of scale deposits (particularly on the heat exchange surfaces), the installation should
be commissioned gradually, starting with operation at minimum power and ensuring at least the nominal
water flow rate of the system before the burner is started up.
• When work is carried out on the installation, it is not advisable to drain the entire system. Only the
required sections of the circuit should be drained.
Protecting the installation against corrosion
The phenomenon of corrosion that can affect the materials used in boilers and other heating installation
equipment is directly linked to the presence of oxygen in the heating water. The dissolved oxygen that enters
the system when it is first filled reacts with the materials in the system and disappears quickly.
Without oxygen replenishment via large water inflows, the plant suffers no damage. However, it is important
to comply with the installation's sizing and operating rules to prevent any continuous penetration of oxygen
into the heating water. If this point is complied with, the water in the circuit will have the characteristics
required to ensure a long installation life: 8.2 < pH < 9.5 and dissolved oxygen concentration < 0.1 mg/litre.
Where there is a risk of oxygen ingress, additional protective measures must be taken. We advise you to call
on companies specialising in water treatment, who will be able to offer:
• The appropriate treatment depending on the characteristics of the installation.
• A monitoring and performance guarantee agreement.
In the case of installations where the water is in contact with heterogeneous materials (e.g. copper,
aluminium), appropriate treatment is recommended to ensure the longevity of the installation.
