Appliance description
The hydraulically controlled instantaneous water heater heats
water as it flows through the appliance. When a tap is opened,
the appliance starts heating automatically at the selected output as
soon as the start-up volume is exceeded (see chapter "Installation /
Specification / Data table"). You can adjust the hot water volume
and temperature at the tap by mixing in cold water.
You can choose between 2 output stages. In addition, 2 output
stages are hydraulically controlled in relation to the flow rate.
The flow meter compensates for pressure fluctuations. The flow
meter ensures largely stable temperatures. The control unit limits
the flow rate, thereby ensuring an adequate increase in the DHW
temperature at all times.
Heating system
The tubular heater heating system has a pressure-tested copper
cylinder. The heating system is suitable for soft water areas (for
application range, see chapter "Installation / Specification / Data
table").
