After 4 months, no white scale was seen, only yellow rust was left. Although there were still substances in the plate heat exchanger, they had been softened This cleint stopped using all additional chemicals and water softening equipment to treat their water as part of this 4 month test. Although there were still substances in the plate heat exchanger, it was soft and could easily be removed manually. There are no more white mineral scales on the heat exchanger plates, only yellow-brown impurities left.
The Knill family in Bernhardzell, Switzerland, was initially skeptical about the Vulcan 5000.

Kitchen utensils with tap water is much easier to clean because there is little trace of limescale. We can only recommend the Vulcan, because it is efficient, easy to install and has no maintenance costs
