Acquaprojet Blue water heaters are equipped with a dashboard with a simple and essential design: 2 knobs allow you to manage all the functions of the appliance in an easy and intuitive way. The models are equipped with an LCD display for viewing the temperature. Guaranteed savings The Acquaprojet Blue line is equipped with the special Economizer device which allows the hot water temperature to be selected as desired, always supplying it at the same temperature even when the quantity drawn varies. An important gas saving is thus achieved, up to 50%, since the insertion of the device allows to limit the maximum thermal power supplied when the usage requirements are limited (low temperature difference or reduced withdrawal flow rates such as for example in the summer).
