types of softener

Ion-exchange water softening technology is well advanced with a variety of softeners offering various features and benefits. Your local supplier will provide guidance on the most suitable ion-exchange unit for your needs. You may be offered cheaper 'physical' devices  which claim to work using magnetic, electrolytic or electronic means. However, although in some circumstances they may reduce the formation of scale in heating systems, they do not soften the water. You lose all the benefits of gentle, soft, scum-free water.

For this reason, we recommend that you insist on an ion-exchange water softener – one that uses salt to remove the hardness. Only an ion-exchange unit can ensure that the hardness is removed.

When the British Water, Quality Water Group studied Physical Conditioners, their conclusions included:

• magnetic, electrolytic or electronic devices ... do not change the chemical composition of the water

• there is no widespread agreement, even among those manufacturing the devices, on how these work

• even when a scale reducer works very well in one home, it may fail to work at all in a different home, even though the conditions appear to be similar.

• insist that [companies] selling scale inhibitors provide an extended-time, money-back guarantee to protect the customer should the device fail to work under the particular conditions in their home.

• a scale inhibitor only reduces scale formation and, as it has no effect on scum formation, it will not reduce the amount of soaps, shampoos and household cleaning products used.

• if you want the full benefits of softened water, eradicating both scale and scum, then you will need an ion-exchange water softener. If you are still not sure which product would suit you best, as with the purchase of any major household item, it is always advisable to deal with a reputable supplier with full range of products able to give you expert advice.

The conclusion is clear. For guaranteed water softening, use an ion-exchange water softener – one that uses salt to remove the hardness. Only an ion-exchange unit can ensure that the hardness is removed.
