After 6 months, almost no trace of hard limescale was visible

I am sending you this letter to inform you that the device is working as it should. Today I moved the heating element of the water heater and found that after 6 months, almost no trace of hard limescale was visible and that a simple soft brush was sufficient to clean it. The last maintenance done on it, prior to the installation of Vulcan, was particularly painful because of the sediments that were proving to be as hard as stone.

At the foot of the boiler, there is now a large amount of limestone powder that the heating element itself has dissolved. My wife has also noticed that the maintenance of the glass wall of the shower cubicle, as well as the taps, was only a simple wipe. Previously, she had to use vinegar to remove the hardest sediment. In the kitchen, the maintenance of stainless steel pots and pans is now much easier. A small drop of vinegar and a minute's wait is enough to remove the few remaining sediments, whereas in the past we had to wait half an hour. (Switzerland)
