Does a water softener need an electrical supply?
Not necessarily, there are some water softeners that will work on water pressure alone, but they are susceptible to varying pressures and flow rates, if your water pressure is adequate then kinetic type water softeners may also be adequate, water softeners that use electricity only do so for the running of a timer, and uses the about the same amount as a kitchen clock, approximately 35-40pence a year, they are also much more adaptable and varied, allowing a much higher degree of control and tailoring to precise household requirements, and are generally cheaper to buy and run.
