Storage Water Heaters

Those who think that such fast heating must come at higher cost may be assured: Viessmann designs all products with sustainability in mind. Therefore, low energy use is a priority for us. Lab tests show that consumers reduce water heater-induced power consumption by up to 16% when using Viessmann devices. This is not only due to the design of the heating rod and water heater case but also because of the way Viessmann processes the inner insulation: during the production process, a patented foaming agent is fully spread inside the heater’s case, leaving no gaps at the outer edges as other products do. This translates into better heat conservation, thus lowering the need for energy.

Vitowell comfort storage water heaters are unbeatable in terms of durability which is enhanced by the heating rod’s nickel-/chromium incoloy. This material resists corrosion even in extreme environments like highly humid climates. This technology, the exclusive Viessmann Ceratech Technology, guarantees maximum corrosion resistance of the water tank. Made out of high-quality ABS material, the housing is splash-waterproof and highly UV resistant. We are therefore able to offer the longest warranty on the market which is up to twelve-years.

Viessmann's German heritage obliges us not only to offer products at high quality but also high safety standards. Our storage water heaters meet EU standards for health, safety, and environmental protection and are developed as per strictest quality standards. Their safety is certified by established German certification institution TÜV SÜD which works at highest standards.
