What is the difference between a timed and metered water softener?
   
 
Time Clock - The more basic water softeners operate on a timed basis. The time clock is set to carry out its regeneration on set days. This is usually calculated by the hardness of your water supply, the capacity of the water softener and number of people in the property. When installed, the softener is set to regenerate at usually 2.00a.m. at the calculated regeneration frequency. To ensure that soft water is always available, the interval between regenerations will be under estimated rather than over estimated.
The softener will then regenerate at this set interval regardless of the volume of water used. If the water usage is low, for instance, one or more of the residence is away, there will be unused softened water capacity at the time of regeneration, which can be argued as an unnecessary waste of salt and regeneration water. Similarly, if there is an increase in your water usage, the softened water capacity will me than likely be exceeded and the water would go hard towards the end of the cycle before the next regeneration. If you are going to be away fromthe property for a period of time, i.e. on holiday, and there will be no water flowing through the water softener it is advisable that it is switched off until your return.
 
 
Metered - Metered water softeners are the most economical softener when it comes to using salt and regeneration water. A metered softener will only regenerate when a pre-set volume of softened water has been used regardless of the number of days this takes.
This avoids under or over regenerating of the softener when your water demand varies. Again the volume of softened water is calculated by the hardness of your water supply, the capacity of the water softener and number of people in the property.
