The unusual design of this tank provides a considerable heating surface (larger than one square meter) wrapped in a special heating cover. Once powered up, the cover reaches a temperature of 120°C and takes the temperature inside the inner tank walls as high as 85°C: this increases the thermal exchange with water and, at the same time, prevents lime scale build-up.
Cold water flowing into the tank from below is conveyed along heated walls, so that the temperature exchange between water and the walls is faster and more effective and water is heated up more quickly.
This results in reduced and optimised power consumption thanks to: i. the heater – which is made up of carbon fibre cables (carbon fibres cut power demand by 40% given the same target temperature), and ii. power splitting (470 W - 1220 W - 1470 W in "Plus" mode).
The process is supervised by an electronic control unit. The control unit, provided with a display unit, is connected to two water temperature measuring probes working continuously: one of them is installed in the lower and the other in the higher part of the tank.
The control unit allows you to:
Thanks to the above, the Water Heater can:
The above performances combined with an electronic control unit allow you to pre-set hot water supplies depending on your actual needs.
