The Viessmann Vitocell heating water buffer cylinders only require a small floor space. Thanks to their elegant design they can always be installed in multi purpose rooms.

Heating water buffer cylinder

Heating water buffer cylinders are cylinders that temporarily store excess thermal energy from heat generators which is not currently needed and transferred back to the heating system when there is a demand again. The heat generators can be boilers, heat pumps, CHP units including micro CHP units, or solar thermal systems. The combi cylinder is a combination of heating water buffer cylinder and DHW cylinder. Heat is transferred for DHW heating via an internal heat exchanger.
