CONSTRUCTION FEATURES
The product is designed to ensure maximum energy saving without compromising final user comfort: the promise is to deliver
domestic hot water regardless the external conditions. Therefore the heat pump group preferably works without the electric
group aid; the heating resistance is switched on only when strictly necessary in order to reach the desired set point temperature
in time; the main board controls the heat pump and resistance state and determines when they shall be
switched on or off. The split configuration ensures space saving and noise isolation; moreover its layout avoids cooling
effect, ventilation constraints and permeability problems.
