Hard Water Problems
What is lime-scale?
Scale mainly consists of calcium and magnesium - two minerals that by themselves have a healthy effect on the human body. However, what is good for living organisms quickly becomes a scale problem as scale deposits in the piping system, in machinery or on surfaces around the house.
So-called hard water holds high concentrations of calcium: the more calcium in the water, the harder the water and more problems.
The birth of scale deposits
Scale builds up as soon as hard water flows through a pipe. Calcium in untreated water crystallizes into a sticky structure (1). These crystals adhere to each other, adhere to surfaces and immediately produce solid scale deposits that have a very destructive effect.
Scale grows in particular when the water pressure changes.
This happens when water changes direction in a bend or intersection which then causes turbulence; or when it leaves the piping system through a faucet. This drop in pressure enhances the formation of calcium crystals, which form a burr-like structure that adheres anywhere.
Scale also particularly forms in warm areas such as on heating elements or radiators. The hotter the surfaces, the more scale will develop. Typical problem spots are heating elements, water heaters etc.
