16.2 Anti-frost protection
The Evolution boiler has a function for preventing damage to the installation by frost. This will
function as long as the appliance remains plugged into the mains. Despite this function, and
particularly in areas with very cold weather, we recommend taking precautions in order to prevent
damage to the boiler. We recommend adding antifreeze to the water in the heating circuit. If the
boiler is to be out of action for long periods of time, we recommend draining all the water and
leaving it empty.
16.3 Boiler water characteristics
In areas with water hardness of over 25-30ºF, we recommend using treated water in the heating
installation, to avoid any scale deposits on the boiler.
It should be noted that even a thin layer of scale deposit will greatly reduce the boiler’s heat
conductivity, causing a major reduction in its performance.
In the following cases treated water must be used in the heating circuit:
- Very large circuits (containing a large amount of water).
- Frequent filling of the installation.
If repeated partial or total draining of the installation is necessary, we recommend filling it with
treated water.
