Introducing the Vitowell comfort Classic

Vitowell comfort Classic: robust and safe

The Vitowell comfort Classic line equips you with a reliable and secure water heater. Viessmann adopts the exclusive Ceratech Technology enamel coating formula to extend the durability of water tanks. Acid corrosion and alkaline resistance, temperature and pressure resistance meet the latest German quality standards to assure long-lasting durability of the heater at its core. An electronic earth-leakage circuit breaker (ELCB) and high-quality, water-resistant casing material provide maximum safety.

Ceratech Technology®

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.

Engineered for safety

The innovative Viessmann earth-leakage circuit breaker (ELCB) safety switch protects you against electrical hazards. The mechanical circuit breaker immediately reacts to any possible electrical leakage. For an increased level of safety, the double-safety thermostats assure that the device is not overheating.

Two design options

Vitowell comfort Classic 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.
