The Ariston Velis is perhaps one of the most eyecatching electric water heaters currently available thanks to its sleek design. The design and the fact it is merely 27 cm (10.6 inches) deep allows you to install it anywhere in plain view. The electric water heater Suitable for both horizontal and vertical installation. 

The ECO function will record water consumption during a week and will then automatically switch to ECO mode. The recorded data the electric water heater can achieve considerable energy savings. The use of two internal tanks means there is less mixing of cold water and less water needs to be heated, so the electric heater power of merely 1500 watt is sufficient. Ideal for a trailer, for instance.
