If, however, the installation requires water treatment: consult us,
particularly for:
- A treatment of the water is in compliance with the use of the
materials used in the construction of the boiler with an aluminium
heating body.
- The precautions to be taken to prevent the formation and
localisation of oxygen in the water in the installation.
- Antifreeze products: ensure that these are compatible with
aluminium and, if need be, with other components in the
installation.
If necessary, our Technical Department is at your disposal.
Renovation of old boiler rooms
If connecting the installation to an old network, we strongly
recommend that you "clear sludge out" of the system before installing
the new boiler.
After carrying out this work, particular monitoring of the installation
may be necessary both in respect of the water in the network and the
quality of the water used for topping it up in order to be in full control
of the consequences.
Suitable filters may be necessary in some cases.
