The body of the Casarte CV gas water heater combines dark stainless steel with a glass display that is also dark and imitates its metal counterpart. In this way, the heater appears to be made from one single material. This impression is reinforced by the fact that there are no screws visible anywhere. The user interface of the display is easily handled, and the device is equipped with safe, eco-friendly technology. A particularly user-friendly feature is the prevention of fluctuations in the water temperature.
