Does the water container of the Truma Combi heater have to be decalcified or sterilised?

For hygienic reasons you should decalcify the water container occasionally. Use special decalcification products from camping specialists or conventional vinegar essence or citric acid, for example. Fill the decalcifying product in the recommended ratio into the appliance via the water system, allow it to work and then rinse the Combi heater thoroughly with fresh water.

Do not use the water from the Truma Combi as drinking water.
