so now it's got me! The thermostat.

Luckily there is a FAQ!

Now my question: I bought Glysantin from ATU today. For the purpose of replenishing the system. Now I've been told by the ATUmänmchen, the destiled water instead of the taps
==References== 
So, was muss nun rein? Destiliertes oder normales Wasser?

Thanks for the answers!
Greetings René
