Well, that really depends on multiple factors, including the water being supplied to you. Some water softeners are more efficient than others and as a result, the operating costs, as well as purchasing price, may vary. When comparing water softener costs it is important to consider the initial price to purchase and install the water softener but also the price to operate the water softener.
There are time operated softeners and water meter-controlled softeners available. A general price range for purchasing a new water softener could be $500 – $1,200. The water meter-controlled units produce the softest water per pound of salt. Some softeners focus on electricity, but some more recent water softeners use water power.
Costs of operating a water softener greatly depend upon the character of water softener and the type of energy that will be used, but also upon the hardness of the water that needs softening and the water usage. When the water is very hard and used heavily, the costs of softening will rise.
Generally, the costs of operating a water softener will vary between $0, $35 and even up to $65 a day. The advantages and long-term cost savings far outweigh the costs of using water softeners.
