What is a Water Conditioning System?

Water conditioner systems are water treatment systems designed to improve the quality of hard water. It does so by either changing the chemical composition of the water or the molecular structure of the hard water minerals.

Types of Water Conditioning systems

Water conditioning systems can be categorized broadly into:

Magnetic Descalers

A magnetic descaler is a magnet that is fitted on the main supply line. It creates a magnetic field on the water changing the shape of hard water ions. Although this method is quite affordable as you do not require electricity or incur other maintenance costs, it is not as effective as the other conditioning systems discussed below.

Electromagnetic Descalers

These are popularly referred to as electronic descalers or conditioners. They are fitted with a magnet or capacitor, which is powered by electricity to produce an electromagnetic signal.

Typically, their design includes wires or cables that transmit the electromagnetic wave to the water, altering the molecular structure of the hard water ions to prevent them from adhering. It also creates molecular agitation of the hard mineral enhancing their flow in the water.

They are easy to install and you do not require to hire a professional plumber or handyman. They have minimal operating costs as the main cost incurred is electricity. Most have a low power consumption making them energy efficient.

Catalytic Conditioners

Catalytic water conditioners are also known as salt-free conditioners or salt-free water softeners. These conditioning systems use a technology referred to as Template-Assisted Crystallization (TAC) to prevent limescale buildup. They have a tank design with TAC media.

The media traps calcium and magnesium ions. It also has nucleation sites where the trapped ions form into crystals that are then released into the water. These crystals precipitate in the water to prevent adhesion. Unlike salt-based water softeners, they do not alter the hardness level of the water.

Catalytic conditioners do not need to be connected to a power source to operate. They have an up-flow design that allows ample time for the ions to precipitate without altering the water pressure or flow rate. The only maintenance required is changing the TAC after 3-6 years. Since the media is resin beads, it does not need to be replaced as frequently as resin beads do.

Chelating Water Conditioners

Chelating agents are chemicals that react with the metal elements in water to form a water-soluble complex. The chelants have a ring center where the metal ions bond preventing them from adhering to surrounding surfaces.

The most common chelants are citric acid and EDTA. Non-phosphorous chelants are the best as they do not cause orthophosphates. Chelants are best used on stagnant water such as spas, pools, and aquariums.

While it is effective, when used in high amounts, it can cause water poisoning. It also strips the water of calcium and magnesium minerals. It is not suitable for treating cooking water.

Salt-based Water Softeners

Salt-based water softeners are a form of conditioning system as they alter remove hardness causing minerals to prevent limescale buildup. They are also known as salt-based water conditioners.

They employ the process called ion exchange whereby hard water is passed through a resin tank. The resin beads in the tank contain sodium ions. During the ion exchange process, hardness minerals in the water are replaced with sodium ions from the resin beads.

Water softeners are expensive and high-maintenance water treatment systems. They are expensive to buy and need electricity to run. They also waste a lot of water during the regeneration cycle to get rid of the hardness minerals in the resin beads.

Soft water has high levels of sodium ions, which may make it unconducive to drinking water. The softening process also strips the water of calcium and magnesium minerals, which have nutritional value. Note that water softeners are banned in states such as Michigan, Texas, California, and Massachusetts.

With that said, water softening systems are highly effective at preventing scale build-up. Some soft water benefits include that it has a slick feel and causes soap to lather easily.


The most common water conditioning systems include magnetic descalers, electronic descalers, salt-free water conditioners, chelants, and traditional water softeners. The right one depends on a wide range of factors. For example, your budget, water hardness levels, the intended use of the water, and many more. Whichever option you choose should be effective at achieving your desired conditioning results.

Which is Better: Water Conditioner vs Water Softener

There isn’t a better option between the traditional water softeners and water conditioners. The right system for treating water hardness depends on your needs and the factors below:

  • Water hardness level
  • Maintenance procedures and costs
  • Whether you are keen on the environmental impact of a given system
  • Whether you are keen on the chemical composition of resultant water
  • Your budget
  • Installation space
  • Effectiveness of the system
  • Size of your residence and water demand
  • The capacity of the given water treatment system
  • Your location

If you are not sure which water treatment system is best for you even after weighing your options against the factors discussed above, it is best to consult with a water treatment specialist.

How Much Does Water Conditioning Cost?

Water conditioning can cost less than $100 up to thousands of dollars. Chelants are the least expensive as they cost between as low as $30. Metallic and electronic descalers are also relatively affordable as cost less than $100 up to $500. Salt-free water conditioners and salt-based water softeners are the most expensive and their price ranges between $300 t0 $2000. When determining your budget, factor in maintenance costs for each type of conditioning system.
