Discover hot water comfort with Vitocell

The large heat exchanger surfaces of the tank coil ensure an abundant supply of hot water and even water temperatures all day long.

In contrast to most conventional direct-fired tanks, indirect-fired Vitocell tanks from Viessmann use the heating water from a boiler to heat the tank water. Space heating and domestic hot water production are integrated into one system for maximum performance and efficiency.

Built to last, with a lifetime warranty

For the Vitocell 300 series, both the tank and heat exchanger of are made of high-grade stainless steel, a material known for its durability, hygiene, corrosion-resistance and long service life. And with a limited lifetime warranty in residential applications, you can be sure your investment will deliver long-lasting value, year after year. For detailed terms and conditions, see the warranty sheet.
