1 Introduction
The AMP ECO water heater stores and heats water for sanitary purposes.
Cold water enters the tank through the water inlet (2). The heated water leaves the tank
at the top through the hot water outlet (1). When hot water is used, the tank of the water
heater is filled with the same amount of cold water.
To operate the water heater, the display (3) is used.
