The Best Electronic Water Descalers to Prevent Rust Formation and Buildup

Writen by Ronald Brown

Fact checked by Natalie Bridges

Limescale buildup can lead to expensive repairs and replacements in your plumbing systems and fixtures. It’s why you need to ensure scale doesn’t accumulate, and one tool to help with it includes the best electronic water descaler.

It can deal with the limescale deposits that collect and settle on home appliances, plumbing fixtures, faucets, and other places due to hard water.

best electronic water descaler

To find the right one, I’ve researched and compiled the top-tier products, listed their pros and cons, and written about their most essential features and benefits. I hope you can find the right electronic descaler that will improve your water supply’s overall quality.

An electric water conditioner is a cost-effective solution for addressing limescale issues in the home. Consider these three factors when choosing the top-quality electric water descaler to make your purchase worthwhile.

  • Type: Electric water conditioners feature either of two types of technology: electromagnetic or capacitive. Most households use electromagnetic water conditioners because they are more affordable. However, capacitive water descalers are on the rise because of better water-conditioning efficiency despite being expensive.
  • Descaling Efficiency: A downside of water conditioners is their limited hard water descaling efficiency. Most electric water descalers can only manage 25 grains per gallon (GPG). Hence, buyers should note the product’s descaling efficiency and compare it with their personal requirements.
  • Compatibility: Electric water conditioners have electrodes that wrap around water pipes to produce an electromagnetic field. Capacitive descalers have sensors that detect electrical capacitance along the water supply line. Sadly, some products might not work with plastic water tubes. So buyers should check if the electric water conditioner they want is compatible with the household plumbing.

Let’s start with the reviews, and then discuss the considerations and answer the most frequently asked questions.

What Is An Electronic Water Descaler/ Who Is This For


The use of hard water often results in the buildup of limescale. Your household plumbing, fixtures, and appliances frequently exposed to hard water are the most affected. Limescale buildup is not just an unpleasant sight, but its removal is also tedious and frustrating.

A water descaler system like the electronic type effectively gets rid of this unsightly buildup. Salt-free water systems are the same as descaling systems. Such systems are also referred to as “salt-free water conditioners.” However, they do not, in any way, soften or descale your water.

An electronic water descaler makes the process of decreasing the effects of hard water possible. It will not convert hard water into soft water, but it reduces hard water’s negative impact.

Based on the studies, when the mineral component is left suspended and hanging on the water’s surface are charged, its overall structure is altered to a circular form. This change in the construction will stop the minerals from forming and thus building scale deposits.

Electronic water descalers increase the solubility of your water’s hard components. As a result, all the hard particles can pass through your plumbing more smoother without causing it to scale. It doesn’t use any salt, and it keeps the required and positive substances in water.

Electronic water descalers are recommended for folks living in areas where the water is not 100% hard. It is also ideal for those who are not agreeable with the expensive cost of water softeners. If you find water softener installation hard and quite a hassle, this is for you.

Since there are zero salts used in the process, this becomes a perfect solution for people who are allergic to salt. Those who have existing kidney diseases and heart problems where salt-based water softeners are not an option may opt for this alternative. Those using tankless water heaters and areas where water softeners are banned can also use this instead.

How Do Electronic Water Escalers Work

The technology and process working behind an electronic water descaler are very cool.

The primary process that sets it apart from salt-based water softeners and other water filter alternatives is the fact that it does not, in any way, remove anything from the water.

As designed, water softeners will be removing contaminants and particles from your water by using a filtering agent in the form of resin or salt. Electronic water descalers are designed differently because they change the water’s molecular structure without taking out anything.

This method will ensure that the water can flow freely and remove the water molecules’ chance of sticking to each other. In the process, limescale buildup would be less likely to occur.

Using a powerful combination of cable/metal and electricity grouping, electronic water descalers build up a force that will alter the water’s molecular structure. The cable bands, or sometimes metal wrapped around the water’s main supply pipe, generate an electromagnetic wave that stops in hardness particles and eventually repositions them.

With this rearrangement happening, the water can flow through the pipes and fixtures and into the appliances in a molecular structure most suitable for your plumbing because the Magnesium and Calcium are converted in a softer and less corrosive manner.

Note that if these molecules are not structurally altered, the minerals that are left suspended become harmful to the metal surfaces of your pipes, fixtures, and appliances with frequent water contact.

Not only will you be faced with limescale buildup but also the risk of clogging and your appliances losing their efficiency. You’d be confronted by potential repairs and replacements, which cost a lot of money.

What Are The Different Types Of Electronic Water Descalers


Choosing the right kind of electronic water descaler is essential so that its primary objective and purpose can be achieved.

The types of electronic water descalers are:

Electromagnetic water descalers – this type is also commonly referred to as magnetic water descalers. This is a plug-in device that homeowners can clip into their incoming pipe. As a result, the established magnetic field alters the properties of the water’s minerals. These minerals are specific to Calcium-Carbonate. The pipes reject these minerals due to the altered components, so the Calcium buildup is prevented.

Capacitive electronic descaler – by far claimed to be the top-tier type of descaler because of the technology-infused on it. Two wires with the water are the components needed to form the capacitor. This capacitor will then store the energy and eventually release it when needed.

Capacitive technology, in most cases, always utilizes water to its own benefit. As the most effective, it is also the most expensive of all. Maintenance-free, you can automatically see the effects in your water after the installation.

DIY electronic water descalers this is your build your own electronic descaler, and the process is not complicated at all. The steps to create one are:

  1. Look for the incoming main pipe of your cold water. This is usually found under your staircase or your sink.
  2. Identify where you will place the two-wire coils along the pipe.
  3. Tightly wind the two coils around the main water pipe.
  4. Attach the main component of the descaler to your wall using a heavy-duty Velcro and plug the two coils.
  5. Your DIY electronic descaler is all set, and you can already turn it on.

Knowing the advantages of every type can help you decide which one is the best for you. One type can be better than the other solely based on how efficient it meets your needs.

The principle it follows is the same, though, regardless of whether it doesn’t remove anything on the water’s components but focuses on altering your water components.

Advantages And Disadvantages Of Using An Electronic Water Descaler

Having a whole-house electronic, hard water conditioner & descaler system have many perks. Depending on your overall water hardness level, this is the solution to having better water quality while at the same time preventing the risks of limescale buildup. Here are just some of the benefits that you get when you opt to use this type of water system:

  • Cost-effective – nothing beats an effective system that is pocket-friendly. You’re not just looking at the system’s initial purchase, but the operational costs and maintenance costs are also affordable. On average, you only need to allocate a budget of $5 to $7 per year for its operation. Maintenance costs are minimal to zero, unlike water softeners with which you need a steady replenishment of salt and filters to be replaced now and then. It doesn’t give your energy a shock because it is low in usage, so your electrical bills would remain pretty much the same.
  • No more limescale buildup – this is one main reason why water descalers are installed, and it does an excellent job of ensuring that you can make the most out of your pipes, fixtures, and appliances. You won’t need to repair or replace it anytime soon because you won’t have ugly scaling problems. Your pipes are also well protected from corrosion.
  • Easy installation – regardless of brand, electronic water conditioners boast an effortless and easy installation process. Homeowners don’t need a professional to get this incorporated into their incoming plumbing system. In about less than an hour, you’ll be all set, and the system will automatically work.
  • Eco-friendly – there will be no high amounts of salt discharge into the groundwater and sewers. It sustains the ecological balance. Lesser plant and animal lives would be disturbed by the high salt content that the ground absorbs.

No product is perfect, and a water descaler also has its shortcomings and drawbacks:

  • Limited use – water descalers don’t work on stagnant water stored in your reservoir. It only works with running water.
  • It doesn’t soften water – you won’t get softer water with a descaler. It will not remove any contaminants and bacteria from your water. Hard minerals would still be present in your water.
  • Maximum Water Level Hardness – if your area naturally has a high level of hardness, the softener’s efficacy might not be as suitable. This system is best only for areas whose water hardness is below 25 grains per gallon.

Buying Guide

Choosing which electronic water descaler can be difficult because there are many great brands on the market today, and the difference between each brand from the other is very minimal. When buying, the brand should be secondary to your decision.

Always remember that what works for your friend or neighbor may not necessarily work for you. It would help if you considered your personal needs because every home is different.

Here are the factors that you need to consider when shopping:

Installation – almost all electronic water descalers are easy to install. But it is understandable that sometimes, non-techie and non-mechanical folks can still be challenged with the process. You have to make sure that you can complete the installation despite not being a DIYer fan. Get a system where the instructions are simple – one that you can comprehend even without any background or prior knowledge in installing such systems. It might be best to go with a brand that can provide support and additional instructions as needed.

Water Supply Capacity and Water Flow Rate – a smaller household size can work with a single electronic water descaler. Still, if your size ranges from mid to extensive household size, you might need more than two salt-free water conditioners to handle your water demand. You also have to take into consideration that water descalers only work when the water is running. This system cannot process stored and stagnant water.

Required maintenance – compared to all other water treatment systems, electric water descalers need the least maintenance, but you also have to consider their longevity and reliability. Should there be any regular maintenance needed, what is the frequency and what needs to be done?

Warranty and Certification – for additional peace of mind, it would be preferable if your choice of descaler comes with CE and FCC certification to UK, US, and EU standards. A warranty from the manufacturer can also allow you to purchase without any stress. You know that the company can provide you with a full refund should you not be fully satisfied with the system’s output.

Package Content – your water descaler of choice shouldn’t be massive that it requires a large space allocation. Your descaler of choice should be space-saving and extremely lightweight for your convenience.

Product Effectiveness – what’s your expected output when you are planning to get a water descaler? Those who want a better quality of water for their overall skin and body care can consider similar feedback like the Hqua 5000e electronic water descaler reviews. After a single use, clothes washed after the water descaler’s installation became softer and smoother on the skin. You have to know the purpose of buying a descaler.

These factors can make your decision-making easier and geared towards your ultimate and unique needs. It would be beneficial at this point to invest some time and effort and research the top electronic descalers that can meet your expectations and essentials. Do not just consider its money back guarantee but also its superbly valuable features.

Can I use an electronic descaler with well source water?

Yes, you can use an electronic descaler with well water to make teeth brushing, showering, car washing, and clothes washing more pleasant.

However, we must caution that most electronic water conditioners can only accommodate water with a maximum hardness level of 25 grains per gallon (GPG) or 427.5 mg/L (427.5 ppm). You are better off with a salt-based water softener if your well water has too many hard minerals.

What are the most trusted electronic water descaler brands?

Purchasing your electronic water descaler can be a little daunting. With so many brands on the market today and each claiming to be the top-rated in quality, functionality, and results, deciding can be intimidating. To help you create a good list of great buys, here are the top and most trusted electronic water descalers:

Eddy Electronic Water Descaler – for that easy installation, eco-friendly, and maintenance-free system. It uses zero salts and maintains all the healthy minerals of your water.

iSpring ED2000 Whole House Electronic Descaler Water Conditioner – a system that can descale your whole household without using any chemicals or salts. This can be easily installed without the need to modify your current plumbing system.

HQUA 5000E Electronic Water Descaler – energy and cost-effective, this is more than capable of dissolving and liquefying limescale.

Scaleblaster – a computerized system that requires zero maintenance with no plumbing modification required during its easy installation process.

Eddy electronic water descaler vs. scaleblaster: Which one is better?

Eddy electronic water descaler and Scaleblaster are two of the top water salt-free water conditioners on the market today. These two brands are guaranteed for their superb quality, efficiency, and reliability.

So, which one is better? Here is an overview of both electronic water descalers:

  • Pipe Size Capacity: Eddy at 1.5 inches and ScaleBlaster at 1.25 inches
  • Grains per Gallon Capacity: Eddy at 20 gpg and ScaleBlaster at 19 gpg
  • Signal Cable Length: Eddy at 5 feet and ScaleBlaster at 46 feet
  • Maximum Range: Eddy and ScaleBlaster both at3000+ square feet

Comparing it with each other, there is not much difference between the two brands. The subtle difference can make you favor one brand over the other, depending on your inclination. Although the ScaleBlaster might be on the upper edge because it can be used both indoors and outdoors, unlike Eddy.

The Eddy, though, is more economically friendly. Again, identifying which one is better is entirely up to you, your needs and preferences, and factors like your actual water hardness level and your house’s size.

What is the difference between a descaler and a water softener?

There are two standard systems for hard water treatment. One is the usual water softener and the other one, is an electronic descaler system. There are also other water treatments that you’d want to learn like an electronic water filter. Understanding their differences can help you identify what the most trusted purification treatment applicable to you.

The main difference between these two systems is the process of treating water. Water softeners alter the water’s chemical composition while a water descaler changes the molecular structure. It charges the water and lessens the effects of the minerals that can cause buildup.
