tank.

Then you can activate powerful operation. The domestic hot water tank will start
heating up the water to the 

Comfort

 temperature.

INFORMATION

happen.

Powerful  operation

 allows the domestic hot water production to be assisted

by the booster heater. Use this mode on days when there is more hot water usage
than usual.
