Top 5 Hard Water Problems for The Home Owner - Page 2
HARD WATER SCALE
Scale is one of the most serious problems caused by hardness mineral deposits. This particular by-product of water hardness puts many water-using appliances out of service. It clogs hot water pipes and can sharply reduce the heating efficiency of a boiler or water heater. When hard water is heated, the scale is formed. This is due to
- the breakdown of calcium and magnesium bicarbonates
- their reversion to the highly insoluble carbonate forms
- their precipitation from the water
- their concentration on the interior surfaces of the water heater
Under certain conditions the deposits form sludges. Both sludges and scale can lead to a sharp reduction in operating efficiency.
