Introducing the Vitowell comfort Premium

Vitowell comfort Premium: Increased efficiency and ease of use

Vitowell comfort Premium is another durable electric storage water heater from the Vitowell comfort product family which is equipped with additional features for even better durability and user comfort. For Vitowell comfort Premium water heaters, Viessmann extended the Ceratech Technology anti-corrosion ceramic layer to the heating element, thus further improving durability of the device. On top of this, Premium heaters come with a convenient temperature LED ring  for easily recognizable hot water availability.

Viessmann adopts the exclusive Ceratech Technology® enamel coating formula to extend the durability of its water tanks. The anti-corrosion function performed by the internal water tank ceramic layer has been developed with decades of expertise and continuous improvement of materials and applied technology. The ceramic layer has a particularly high density and a perfectly smooth surface, undergoing a 100% quality check off the production line. Acid corrosion resistance, alkaline resistance, temperature and pressure resistance - all these technical characteristics are in line with the latest German quality standards to guarantee a long-lasting durability of the heater at its core. 

Premium heaters are not only equipped with a ceramic coating of the water tank; also the heating element has been coated. This adds a layer of protection to the heating element and makes both, tank and heating element, more durable.

With the help of a precise temperature regulator, the water temperature of your Vitowell comfort Premium can be adjustment stepless. A LED ring indicator changes light from orange to blue when the heating process has been completed.

Vitowell comfort Premium heaters are available in two designs: cube and slim. The slim heater sticks out by its simplistic, modern design. Thanks to its shape, it can also be concealed in a false ceiling. The traditional, compact design makes the cube heater particularly suitable for small bathrooms.
