Stainless steel hot water cylinders - advantages and product range

Stainless steel hot water cylinders for perfectly hygienic hot water supply

A decisive advantage of stainless steel hot water cylinders is their chemical composition. In accordance with the most stringent requirements, the metal is refined with additional alloying elements such as chromium, molybdenum, and manganese, making it highly resistant to rust. Since no additional protective layer is applied, as with enameled cylinders, deposits caused by residues build up over time are prevented. Therefore, Viessmann stainless steel hot water cylinders guarantee perfectly hygienic hot water throughout their entire service life. Furthermore, eliminating the need for a protective anode reduces maintenance costs, even reducing replacement if necessary.

Additional economic benefits of stainless steel hot water cylinders

In addition to high levels of hygiene and water quality, stainless steel hot water cylinders are impressively energy-efficient. They are encased in highly efficient multi-layer insulation made of rigid foam, polyester fleece, and innovative vacuum panels. As a result, they operate virtually without heat loss, which is evident at first glance: Viessmann stainless steel hot water cylinders are rated in the new, highest ErP efficiency class, A+. Compared to hot water cylinders of efficiency class A, the previously highest class, these new appliances save up to 22 percent on energy costs.

Less weight with the same cylinder size

Another advantage of stainless steel hot water cylinders, which becomes apparent even before they are put into operation, is their weight. Compared to enameled cylinders, stainless steel hot water cylinders like the Vitocell 300-V and Vitocell 300-W are almost a third lighter—while remaining the same size. This reduced weight not only facilitates transportation, but also makes on-site installation much simpler for contractors. Furthermore, the dimensions and connections remain identical to those of A-marked cylinders made of enameled steel. Therefore, old cylinders can be replaced quickly and without any major modifications.

A wide selection of stainless steel hot water cylinder fittings

A suitable cylinder makes a significant contribution to economical operation. Viessmann offers a suitable stainless steel DHW cylinder with the required capacity to meet any requirement. For example, the Vitocell 300-V is a stainless steel DHW cylinder with a capacity of 160, 200, 300, and 500 liters. The Vitocell 300-H , on the other hand, is ideal for installation under a water heater. Made of corrosion-resistant stainless steel, this DHW cylinder holds 160, 200, 350, or 500 liters, depending on the version. The Vitocell 300-B stainless steel DHW cylinder with a capacity of 300 or 500 liters is recommended for use with solar collectors for heating.
