What is Limescale?

Limescale is mineral buildup from hard water found in hot water appliances and household pipes. Since about 85% of American households have hard water, it is a common problem that not only leads to increased energy bills and reduced water pressure, but everyday frustrations such as spotted dishes.

You may be experiencing limescale problems in your home, costing you money on both energy bills and broken appliances, if you are:

  • Seeing spots on freshly washed dishes out of your dishwasher (or on the interior of the dishwasher)
  • Noticing reduced water pressure
  • Experiencing a long wait for hot water
  • Detecting traces of limescale in your coffeemaker, showerhead, tub and faucets

Visible evidence of limescale is usually confirmation of a much larger problem. If any of the above hints ring a bell, chances are your hot water appliance pipes and household plumbing pipes are clogged with mineral buildup.

How is Limescale Formed?

Limescale is formed from naturally occurring minerals in hard water: Carbonate (lime), magnesium carbonate, calcium sulfate, calcium phosphate and sediment formations. When these minerals are exposed to high PH levels, increased temperature or pressure changes, they crystallize and attach to surfaces. This is why limescale is so prevalent in appliances such as hot water heaters, dishwashers, clothes washers, showerheads, and faucets.

The Effects of Limescale

Limescale negatively effects both insulation on heating elements in your pipes and and temperature sensors. The buildup of limescale on heating elements creates insulation that reduces the transfer of heat from the heating elements into the water. The presence of limescale does not allow water to make contact with temperature sensors in pipes. This causes readings to call for more heat when, in reality, the temperature may be higher than indicated and extra heat is unnecessary. In both cases energy is wasted due to limescale in even the most energy-efficient appliances and technologies.

Limescale buildup

Limescale wastes a significant amount of household water by running water for extended periods of time while waiting for it to get hot.

The buildup also causes corrosion in pipes and appliances, increasing both repairs and early replacement. With many appliances, damage from limescale is not covered under warranty. In fact, according to a recent Battelle Institute study, hard water can lead to as much as a 48% loss of efficiency in water heaters. The same study found showerheads lost 75% of their flow rate in less than 18 months due to limescale buildup. The study additionally found tankless water heaters operating in hard water failed after only 19 days of testing.

The good news is an easily installed, environmentally friendly, cost-effective HydroCare unit not only reduces spotting on dishes, shower doors, tubs and faucets, but also removes existing limescale buildup and prevents more from forming, saving homeowners from high utility bills and appliance breakdown. One unit has the strength to protect a home’s entire plumbing system and hot water appliances.

Please Note: HydroCare units are engineered for the US electrical specifications and for the appliances and plumbing system in residential homes. Warranties and guarantees are valid only when sold through authorized dealers.
