Electronic Water Descalers – Water Descaler Technical
- Substantially reduce scum marks on sinks, baths, and kettles.
- Chemical-free solution to water descaling and softening.
- No moving parts – fit and forget.
- No need for regular refilling or maintenance.
- Self-monitoring – indicates any system fault, internally or externally.
- Reduces reliance on cleaning products that are less effective in hard water.
- Does not affect the chemical composition of water – safe to drink.
- Relatively low-cost solution.
- All the benefits attributed to softer water – kinder to skin, hair, etc.
- Less detergent required.
- Reduce heating costs by preventing scale build-up inside systems.
- Quick installation – no plumbing required, plugs into a standard outlet.
- Helps avoid premature replacement of boilers, pipework, showers, and appliances.
Hard water is rich in calcium and magnesium minerals. While not harmful in itself, these minerals create limescale, which leads to multiple problems:
- Scale build-up in bathrooms and kitchens, especially around outlets.
- Colours in laundry can seem faded.
- Appliances and heating systems clog with mineral deposits.
- Reduced efficiency and lifespan of appliances.
- Dry, brittle, or irritated skin and hair.
- Soaps and detergents form soap scum, difficult to wash away.
- Lingering stains on glass and surfaces.
- Aggravation of eczema symptoms such as redness and itching.
Over time, scale acts like insulation inside pipes and tanks, reducing efficiency and restricting water flow. The efficiency of heating systems can also decrease over time as the mineral buildup act as an insulator. Hard water can also lead to skin and hair problems too. Find out the effects of hard water on skin and hair.
Electronic water descalers (sometimes called water conditioners) are small devices fitted next to your main water pipe. Coils of wire are wrapped around the pipe, emitting a controlled electromagnetic field.
Unlike traditional softeners, descalers:
- Do not change the chemical composition of water.
- Keep beneficial minerals such as calcium and magnesium.
- Prevent limescale formation rather than removing minerals.
They are cost-effective, easy to install, and suitable for both domestic and commercial properties.
Descalers alter the form of calcium carbonate without changing it chemically. This keeps minerals suspended in the water instead of forming solid limescale deposits.
The process uses a computer-controlled, time-variant magnetic field that is harmless to humans. Unlike static magnets, the waveform frequencies are optimised to stop scale from forming.
Benefits:
- No added chemicals or salt.
- No effect on water pH.
- Safe for drinking and cooking – no salty or metallic taste.
The University of Bath tested electronic water descalers and demonstrated measurable reduction in scale deposits. Compared with an untreated control, 10mg less scale formed per 300mm of 25mm pipe over 30 days.
Water Descalers – Pros
- Easy to install, minimal maintenance.
- Prevents scale build-up.
- Keeps beneficial minerals in water.
- Low running cost.
Cons
- Water does not feel “soft.”
- Does not remove existing scale deposits.
Water Softeners – Pros
- Removes hard minerals completely.
- Produces soft-feeling water.
- Better for areas with extremely hard water.
Cons
- Expensive to install and maintain.
- Requires salt refills and wastewater for regeneration.
- Can leave water with a salty taste.
How is hard water treated?
Hard water can be addressed with either an electronic descaler or a water softener. Descalers alter mineral behaviour, while softeners remove minerals entirely.
Do electronic water descalers really work?
Yes. Independent testing has shown significant reductions in scale build-up by altering the behaviour of calcium and magnesium ions.
Do descalers increase the water bill?
No. Descalers use only a few watts of electricity, costing around 18p per month. They use no additional water.
