When you heat hard water, it forms scale around the heat source.
The most obvious place to see this is in your kettle, where the element becomes scaled up over time and either needs cleaning or replacing.
This scaling effect is also happening inside your hot water system, although you never see and cannot clean it easily.
How scale affects your heating system
Scale is a fantastic insulator and when it forms around a heat source, it traps heat in. As you can see in this diagram, the layer of scale needs to be heated first before any heat reaches the water. To heat the scale you use more energy, which is reflected in your gas / electricity consumption. A scaled up heat source cannot work as efficiently as it was designed to. The more water you heat, the more scale you produce, the more energy is required, and so the vicious circle goes on.
In this diagram you can see a scale free heating element. Without any scale the heat is transferred directly into the water and much less energy is used to achieve the desired effect.
The Battelle Study (WQA 2009) drew the following conclusions:
“Gas storage tank household water heaters operated on softened water maintained the original factory efficiency rating over a 15-year lifetime”
“Hard water can lead to as much as a 24% loss in efficiency in water heaters”
How will a water softener help?
Soft water will dissolve away any existing scale that has formed throughout your entire system. Because the hardness minerals have been removed from your water, no more scale will build up. This means not only will soft water return your heating element to full working efficiency, it will also keep it that way for good.
And of course, reducing the amount of energy you use will reduce the amount of money you spend on fuel. With fuel prices rising dramatically, this cost saving will only increase as time goes on.
