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.

Our heating water buffer cylinders are designed to be combined with a variety of heat generators such as solar thermal systems, heat pumps and solid fuel boilers. With a capacity range of 200 - 2000l depending on the model, we have a solution for every need including multiple flow and return connections, plus additional connections for test points. All-round, high grade thermal insulation ensures heat losses whils the optional Vitotrans 353 freshwater module, available as an accessory, allows for hygienic DHW heating in accordance with the instantaneous water heater principle.
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.
Our heating water buffer cylinders are designed to be futureproof and are compatible with a variety of alternative fuel source heat generators.
We always recommend the installation of a solar thermal system to help you to save energy and also save money when heating water in your home.
The quality of the inner surface of the DHW buffer cylinder is crucial to providing DHW hygienically. For this reason, Viessmann 100 series buffer cylinders relies on a Ceraprotect enamel coating for safe and hygienic DHW with lasting protection against corrosion.
