Discover hot water comfort with Vitocell

Vitocell 300-W domestic hot water tanks are  made of high-alloy stainless steel to satisfy the highest expectations with respect to hygiene, recovery rates and service life expectancy.  The large heat exchanger surfaces of the tank coil ensure an abundant supply of hot water  and even water temperatures all day long.

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.
