Does the Truma electric boiler need to be maintained?

For hygienic reasons, we recommend that you regularly decalcify and sterilise the entire water system. This can be done with special products from specialised dealers or with commercially available products like citric acid or vinegar essence. Products containing chlorine are not suitable.

So that no microorganisms infest the Truma electric boiler, you should regularly heat it to 70 °C.
