Water plays a major role in every aspect of our lives. This includes everything from how we hydrate our body to how we keep it clean. We also use it to ensure that the environment we live in is sanitary.

With that said, it’s not surprising that we should all strive to have the best quality water in our pipes.

How can we achieve this? One of the most straightforward solutions you can do is to use the best electronic water descaler.

What Is an Electronic Water Descaler?

Depending on where you are located, more often than not, the water entering your home is actually hard water. This type of water contains high levels of minerals.

What is hard water?

Before it reaches your home, water passes through deposits of gypsum, chalk, and limestone. This natural occurrence then produces hard water containing magnesium and calcium sulfates, bicarbonates, and carbonates.

With hard water, you would often find water spots forming on your dinnerware, faucets, and other plumbing fixtures. What’s more, it makes your skin feel dry, takes away the shine from your hair, and makes you use up more detergent when washing clothes.

If you want to solve this problem, the solution is simple: get a water descaler!

How Do Electronic Water Descalers Work?

An electronic water descaling system, unlike water softeners, does not use salt. Instead, it changes the structure of the water down to the molecular level by using an electromagnetic wave.

Through electricity and the metal bands wrapped around the main water supply, the hard particles in the water are stopped and rearranged. As a result, you get better-quality water without having to remove the minerals from it.

Here are the Best Electronic Water Descalers in 2022

Finding an electronic water descaling system that meets your household’s needs can be a tough project. This is especially true because of the wide selection you’d find.

Buying a Water Descaler System? Here’s what you need to know

Finding the right unit for your home could prove to be a challenging task, especially if you don’t have any idea of what you’re looking for.

In that case, we’ve got your back!

To help you choose, we’ve listed the most important factors you’d want to take into consideration when deciding on which water descaling system to buy.

Water Hardness Level in Your Area

Before anything else, it would be wise to know the hardness level of the water supply in your area.

Try to find out what the ballpark number is. In this way, you will know if the descaling unit you’re looking at can or cannot handle the water that’s in your pipes.

Look for a model that is strong enough to work on water supply with a hardness level of anywhere from 19 to 25 gpg. Any more than this might require the use of a water softener instead.


Similar to any other product you wish to buy, also check out the brand you’re purchasing the descaling unit from. When you do, you will know whether or not they offer a guarantee or warranty service on their products.

Getting to know the brand also means you’d see if they offer reliable and accommodating customer support.

Free Space

The system you choose would also depend on the free space you have at the main pipe. It should be large enough to accommodate the unit. Also, there should be enough free space to which you will need to wrap the coils/bands.

Electricity Consumption

These are electronic devices, so they would need to be plugged into the wall. If the reason you’re buying a descaler is that it’s more environment-friendly than a water softener, also check out how much electricity it eats up.

Still, compared to its counterparts, this type of descaling system is the most economical.

Ease of Installation/Use

Finally, you should also make sure that the unit is easy to use and install. It should not require the help of a professional plumber, and there should be no modifications to the house’s plumbing system.

Aside from that, it would also help if there are indicator lights on the unit. These will help you determine if the device is running or not. In this way, you can be sure that it’s working hard to make your water supply better.

Which is better: electronic water descaler vs water softener?

With all these talks about water descalers, you might be asking: how does it differ from a water softener?

We believe you already have more than a slight idea as to what these two technologies are. While both of them work on water, they differ in a couple of aspects. You can see the most significant difference in the kind of water each one produces.

A water softener treats hard water to “soften” it, which basically means changing the composition of the water by removing the “hardness” brought by magnesium and calcium.

Then again, we need these minerals.

As such, more and more households are choosing an electronic water descaler instead. This device uses electromagnetic technology to make hard water become “soft” without getting rid of essential minerals.

How to install the Eddy electronic water descaler?

Regardless of the brand and model you are planning to get, installing an electronic water descaling system is quick and easy. In fact, many can attest that it would not take you more than 30 minutes to do everything by yourself!

Also, the unit will most likely come with an instruction manual, so you really won’t have to worry about doing any research to find out how it’s done.

Nevertheless, here is a step-by-step guide you can follow:

  • Step 1: Wind the Coils

The package will include two sets of coils, which you would need to wrap around your main water line. By this, we mean the main pipe from where all the water supply in your house comes.

  • Step 2: Mount the Unit

Once you are done with that, you can then begin mounting the unit to a nearby panel or wall. There’s no need to worry about mounting hardware, too, as the package already comes with adhesive pads.

Both ends of the two coils feature a jack each. Plug them into the main unit, depending on the color.

  • Step 3: Connect to Electrical Supply

Finally, plug the main unit into a wall socket nearby or use an extension wire. Turn it on to check if all the indicator lights are on, which signifies the unit is now at work.

What are the benefits of using an electronic water descaling system?

Are you still having doubts about getting a descaler for your home? Well, we’ve got news for you.

To help you decide if it is indeed a wise buy for your household, here are the different advantages of an electronic descaler:

Longer-Lasting Plumbing System

This innovative device prevents the build-up of limescale, which can cause pipes to get clogged and hinder water flow. In time, this would mean that you will have to replace the damaged pipes and buy new ones.

Obviously, if you don’t do something about that build-up, the same thing will happen again in the future. Enter the electronic descaler.

With this device, not only will the build-up be prevented, but existing deposits will also be eliminated. It will take some time, but you can trust that the constant flow of conditioned hard water will solve this problem.

Appliance Protection

In line with better plumbing system health, your appliances will also benefit from this device. Of course, this can only be said about appliances that use water, such as ice makers, electric kettles, coffee makers, dishwashers, and washing machines.

Health Benefits

If you have sensitive skin, then you probably experience itchiness, redness, and dryness because of hard water. A descaler will help you achieve a softer feel on your skin, so there’ll be less irritation.

Aside from your skin, your hair will also benefit, resulting in a shinier and healthier appearance. (Source)

How soon will you see results?

As soon as you plug the device in and allow it to run, the descaling process starts, and you can expect that there would be no further build-up.

However, limescale deposits that are already in the pipes would take months to get eliminated. This means that the sooner you get a unit installed in your home, the sooner you’d see results.

How long will a descaler last?

As you may have noticed, the coils/bands are wrapped around the pipe. As such, they won’t be in contact with the moving water. Basically, no part of the entire system moves, and there are also no chemicals involved in the whole process.

An electronic water descaler, then, will last similar to any other electronic device.

While it requires no maintenance, it would be wise to check it out once in a while to see that all the indicator lights are on. This would indicate that there are no problems within the unit and that it is working as it should.


While softened water may sound like the best choice for your home, we believe that opting for conditioned water instead is better. With this, you won’t be removing the naturally occurring calcium and magnesium in your water supply, something our bodies would be thankful for.

To achieve this, all you need to do is find the best electronic water descaler that has the right features to match your needs.

After carefully reviewing the list of the best choices we looked at, we have concluded that the wisest choice would be the HQUA 5000E.

Although the brand may not be as experienced as Eddy or Scalewatcher, the fact that it can handle water with a hardness level of 25 gpg is more than impressive. Another reason is the fact that it consumes less than 10 bucks worth of electricity per year!

If this model does not meet your requirements, though, you can always check out the other options we looked at. Again, these are all from trusted brands, so you can rest assured that your investment won’t go to waste.
