What is an electric water softener?
An electric water softener is a device used to soften a property’s water supply. It removes magnesium and calcium from hard water through a process called ion exchange to prevent limescale building up in household appliances, boilers or pipes. For a complete understanding on how this process works, check out our How a Water Softener Works guide.
Having softened water in your home brings many household and health benefits, as well as cost savings. You can choose from an electric or non-electric softener; we’ll explain what the difference is between the two here. The Harvey Water Softener™ is a non-electric water softener.
How do electric water softeners work?
Electric water softeners work in a very similar way to non-electric water softeners like those sold by Harvey Water Softeners™. Unlike non-electric water softeners, electric water softeners use an electric timer to work out when to regenerate the resin bed inside the tank.
At a set time, usually once a day, the timer tells the water softener to flush the resin bed with water and salt so it can continue softening water. This means that cleansing of the resin in the water softener is controlled electrically, therefore, there are times where the resin bed is cleansed without actually needing it yet. This is a waste of resource due to the design of electric water softeners.
Some makes of electric water softener come with a single tank. This works fine until the time comes for it to regenerate, at which point it can no longer soften water until the process is complete. This can leave your home without softened water for a period of time.
Electric vs non-electric water softener
Non-electric and electric water softeners are very similar in their results; both deliver softened water that prevent the buildup of limescale around the home.
The big difference between them is the fact that non-electric softeners work on a geared, throughflow model, rather than an electric timer. The water displacement meter in a Harvey Water Softener™ (which is non-electric) has been developed so that it only triggers the cleansing process when enough water has passed through it to deem cleaning necessary.
This means that the resin bed is only regenerated when it absolutely needs it, once a certain volume of water has passed through and been softened and the resin has been completely used up. The benefit of this over a timer is the fact that it wastes less water and salt, both of which cost money.
The Harvey Water Softener™ in particular uses a twin cylinder design, which means that when the cleansing process is triggered for one cylinder, the other cylinder takes over the job of softening, meaning you get softened water 24 hours a day, 7 days a week.
