Electronic Water Descaler Pros and Cons

Hard water can lead to a myriad of problems in your home, from ugly scale deposits on faucets and fixtures to low water pressure and reduced lifespan of your appliances.

It can also interfere with your cleaning tasks by weakening the effectiveness of detergents and leaving stains on your clothes.

Installing an electronic water descaler in your home will come in handy. It’ll help you fight limescale and deal with the stubborn hard water without eliminating the healthy calcium and magnesium minerals.

What is an Electronic Water Descaler?

Also known as a water conditioner, an electronic water descaler is a high-tech, eco-friendly device that creates a magnetic field to change minerals in your water using a low voltage current.

The charge changes the way these minerals behave and makes them stay in the water instead of building up in your appliances.

This helps reduce the effect of hard water on the appliances and helps prevent future scale buildup from the minerals.

Types of electronic Water Descalers

There are 3 types of electronic water descalers; capacitative electronic descalers, electromagnetic water descalers and DIY electronic water descalers.

1. Capacitative Electronic Water Descalers

Although highly effective, they are the most expensive electronic descalers today.

A capacitative water descaler has 2 wires and a capacitor that stores energy until it’s needed. They give instant results and are easy to maintain.

2. Electromagnetic Water Descalers

These descalers are the most common options and are inexpensive.

For the best results, you need to attach an electromagnetic descaler onto the incoming water pipe. It alters the behavior of hard water minerals and prevents limescale buildup.

3. DIY Electronic Water Descalers

Though uncommon, DIY descalers are usually made by persons with excellent DIY skills. To build one, follow these simple steps:

  • Find your home’s main incoming water pipe
  • Locate the best installation point for 2 wire coils
  • Wind the coil around the pipe
  • Attach the main component to a wall and plug in the coils
  • Connect a power cable and switch it on

Benefits of Using an Electronic Water Descaler

Listed below are reasons you need to get an electronic water descaler for your home.

Electronic Water Descaler Pros and Cons
  • Reduces Scale

Electronic water descalers reduce limescale. And reduced lime scale means less cleaning work.

Limescale, which commonly builds up around faucets, is quite hard to remove. Eliminating it requires special cleaning products and chemicals that are not only costly but also unsafe to use in your home.

With an electronic water descaler, there’s less or no buildup at all, meaning that you’ll have an easier time cleaning your bathroom and kitchen.

  • Environmentally-Friendly

Electronic water descalers don’t require a lot of electricity to operate or produce a lot of waste water. They, therefore, make an effective, environmentally-friendly water softener alternative.

These systems don’t require salt or water to operate; they simply produce an electromagnetic wave that alters how hard water ions behave.

  • Affordable

Compared to salt-based water softeners that cost at least $500, you’ll pay between $100 and $300 for an electronic water descaler.

These systems are also easy to install, meaning that you don’t need to hire a plumber to do the work for you.

In terms of maintenance, you won’t need to factor in the price of new resin or salt, as electronic descalers don’t need any of these to operate.

  • Easy to Install

Since an electronic water descaler requires installation outside the waterline, you only need to follow a simple set of instructions to set it up.

In fact, with just basic DIY skills, you can install it in less than an hour. You just need to get the best location for the installation, wrap the cables around the pipe and install the system on the wall behind it.

Next, connect the unit to a power outlet, and it’ll start working immediately.

Uninstalling the system is also easy when moving house or if you don’t want to use it anymore. You just need to do the opposite of what you did when installing the unit, unscrew it and leave the pipes as they were before.

  • No Maintenance

After installing the electronic descaler, that’s it! You don’t have to do anything else in the form of maintenance.

There’s no resin to keep track of or salt to top up. All you need is access to a constant source of electricity.

Zero maintenance means more benefits when it comes to cost. You won’t require a monthly budget to keep the water conditioner working at its best. You can as well just set it up and forget everything about it.

Disadvantages of Electronic Descalers

With advantages come disadvantages. The following are the disadvantages of electronic water descalers.

  • Do not Soften Water

Electronic water descalers don’t soften water; they just prevent hard water minerals from sticking to surfaces. And because of this, they don’t offer any proof that they are actually doing their job.

You’ll find only that they are indeed working if there’s a reduction in scale.

  • Require Flowing Water

Electronic water descalers only work with flowing water, which is why you have to install the unit at your home’s water line. Don’t try using it on stagnant water, as it won’t work.

  • Not Effective in Areas with Extremely Hard Water

If you reside in an area with very hard water, an electronic water descaler may not work for you. This is because some hard water minerals may still pass through the area of the pipe where the system is installed.

If your home’s water hardness is more than 25 grains per gallon, an electronic descaler might not give you excellent results.

Do Electronic Water Descalers Really Work?

Yes, electronic water descalers do work. They will prevent/reduce limescale buildup and prevent damage to your home appliances.

Electronic descalers make cleaning easier and prevent dry skin and hair, especially for persons prone to eczema.

However, it’s important to note that an electronic water descaler won’t soften your water. It only prevents the effects of hard water.

Consider a water softener if interested in a system that’ll treat your hard water and remove its effect.

Is a Water Descaler Worth it?

Of course! It’s worth it, as it’ll prevent the effects of hard water like limescale buildup on faucets and fixtures. It’ll also prolong the lifespan of your home appliances.

Are Water Descalers Safe?

Water descalers are safe to use and produce water that is safe to drink for humans, animals and plants. The water doesn’t have any added sodium, and the essential minerals are still there.


An electronic water descaler is one of the most effective and inexpensive ways of preventing limescale buildup. The ease of installation and maintenance makes it an excellent fit for any home or business.

The system improves the efficiency of home equipment and appliances like dishwashers, washing machines and tanks while eliminating frequent repairs.

And although the descaler doesn’t soften water, it offers more benefits that make it a worthy investment.
