also for renewable use – is a combined buffer cylinder that works according to the tank-in-tank principle. The heating water in the buffer cylinder can be heated through a large solar exchanger coil in the bottom part or by a solid fuel boiler. In the top part of the buffer cylinder, there is a second, smaller domestic water cylinder. This means that large quantities of hot water up to 30 litres per minute are available for use. The domestic water is heated by the heating water in the buffer cylinder; but it is also possible to heat it through a gas or oil boiler. Storacell Eco CBSA is available in five sizes with volumes from 500 to 1500 litres (heating and domestic water).
The Storacell Eco series also includes the buffer cylinder Storacell Eco P 750 S-solar for solar heating support and a large number of universal buffer cylinders for operation with freshwater stations and renewable energies.
Freshwater stations are the ideal solution for hygienic instantaneous water heating. Beside freshwater stations for single- and two-family homes, Junkers now offers freshwater stations for up to 20 apartments. A single device heats up to 40 litres per minute, while a cascade arrangement even provides for up to 80 litres of hot water per minute (at 75 °C buffer cylinder and 60 °C hot water outlet temperature). Freshwater stations are particularly suited for the combination with solar systems, heat pumps or solid fuel boilers as they generate very low return flow temperatures to the buffer cylin-der. Moreover, due to their particularly hygienic water heating method, freshwater stations are perfectly suited for the sanitary needs of buildings that are not permanently used, like sports facili-ties.
For solar domestic water heating and heating support, Junkers pre-sents a new modular system: the large solar system LSS-TF for multi-family houses with up to 20 apartments, smaller hotels and similar buildings. The system includes preconfigured components as well as the solar energy centre with solar station and controller, the Junkers flat collectors (20 to 100 square metres of collector area), one or two freshwater stations and one or two buffer cylin-ders
