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.
