The Vitocell 300 is the leading tank series in the Vitocell line of domestic hot water storage tanks. It?s extremely durable, efficient, hygienic and provides all the hot water you need. For the Vitocell-B 300 the heat from solar collectors is transferred to the water via the lower heat exchanger coil. The upper heat exchanger coil accommodates reheating by the heating boiler.

The narrow, cone-shaped heat exchanger coils and their design provide maximum energy transfer in connection with Viessmann solar collectors.

  • Stainless steel domestic hot water tank for hygienic domestic hot water heating.
  • Dual heating exchanger coil for solar heating applications in conjunction with solar collectors and a heating boiler.
  • Long service life due to corrosion-resistant hot water tank and heat exchanger coil construction of high-alloy SA240-316Ti stainless steel.
  • No sacrificial anode required for additional corrosion protection; therefore no anode replacement costs.
  • Heating of the entire water content by a heat exchanger coil extending to the tank bottom.
  • Reliable hot water comfort due to fast, even heating with large-diameter 1"/25 mm non-finned heat exchanger coil.
  • Minimal standby losses through highly effective foamed-in-place or wrap-around HCFC-free insulation.
  • Two thermometers to show the domestic hot water temperature at the top of the tank and at midpoint.
