Why do we even need to decalcify?
In the last article we learned, how the lime gets into the water. This is actually a so-called saturated solution, which means that under normal circumstances the lime remains a component of the water. After treatment in the waterworks, this lime-containing water is brought into the house through our pipes. When this water is heated, the lime dissolved in the water turns back into limestone. precipitation.
This process is intensified as soon as the water reaches a temperature of 55 to 60 degrees Celsius. You can therefore protect yourself from excessive calcification of the equipment, for example, by keeping the operating temperature below this critical limit. This is possible without any problems in modern heating systems, for example. But unfortunately, this simple measure cannot be applied everywhere. A coffee machine that produces coffee only with a water temperature of 60 degrees produces only a warm brew.
The lime is best deposited in our coffee machines on the wall, on the floor or on the heating coils. All appliances with such heating coils, such as coffee makers, kettles, washing machines, etc. become real power guzzlers, because energy must first be used to heat the lime before the water is heated. Metallic pipes and valves also become clogged with lime over time.
Therefore, the deposited lime should be dissolved from time to time. For this purpose, one usually uses an appropriately suitable descaler.
