Hard Water Areas; Normally it is not a problem to install a heat pump in hard water areas since the normal
domestic hot water working temperature will be not greater than 60°C . In areas where exceptional water
conditions prevail, consideration may need to be given to the fitting of a device capable of inhibiting scale .
In such circumstances the advice of the local water authority should be sought .
