WATER TREATMENT
•
The hardness of the mains water supply conditions the frequency with which the heat exchanger
is cleaned.
•
In hard water areas where the main water can exceed 15°f total hardness, a scale reducing
device is recommended. The choice of this device has to be made taking into consideration the
water’s characteristics.
•
In order to improve the resistance to lime scale, it is recommended to adjust the domestic hot
water temperature as near as possible to the one you really require.
•
The use of a modulating room thermostat reduces the dangers of lime scale formation.
•
We recommend you to check the state of cleanliness of the domestic hot water heat exchanger at
the end of the first year and subsequently, on the basis of the amount of lime scale found, this
period can be extended to two years.
