Function; Hot Water Demand - Austria Email SISS 350/100 Instrucciones De Uso

FUNCTION

The service water stored in the internal boiler enamelled according to DIN 4753 is heated indirectly by the sur-
rounding heating water. The buffer content (heating water) can be heated indirectly by means of a large-surface
pipe register that is welded in permanently, and/or directly through the coupling sleeves by means of a boiler,
heat pump, solar system, screwed-in heating for the buffer area and a built-in heating for the service water area.
The array and number of sleeves, as well as the pipe register that is available on various models allow a multivalent
operation.

The temperature of the cold water required for mixing to the specified hot water temperature was estimated at
approx. 12 °C.
Due to the hysteresis of the temperature control (± 7 K) and possible radiation losses (cooling-down of the pipe-
lines), the temperature specifications are subject to an accuracy of ± 10 K.
