Επειδη ειχα στειλει ενα email τοτε στην Eheim για το θεμα των thermoφιλτρων, σας παραθετω την απαντηση τους :
Dear Vasilis
Thank you very much for your inquiry by email. The heating element of the wet/dry thermofilter for fresh water is not resistant by using marine water. The heating element will rust.
It is possible to change the heating element of your filter in a marine resistant version – but this is only possible here in Germany. We therefore kindly ask you to send your filter to our service department:
EHEIM GmbH & Co. KG
Plochinger Strasse 54
73779 Deizisau
Germany
We can change the heating element. The costs therefore are about € 61,36 plus tax and the costs for the transport.
I hope that this information is helpful for you.
If you have further questions please don't hesitate to contact us again.
With best regards
i.A. Cornelia Veith
