Do *NOT* Buy An Eddy Electronic Water Descaler Until You Read This

Last Updated on March 16, 2021

The Eddy Electronic Water Descaler is sold as an alternative to buying a water softener. But is it really as good as a softener? This article will explore.

Now it is very important that we clarify something before proceeding. This is not a water softener. Yes, it claims to solve some of the same problems as a water softener.

But it does not soften water.Aquasana Whole House Features List

The electronic water softener Eddy is a salt-free solution for limescale problems.

This means that the chemical composition of your water does not change. Instead it changes the way your water reacts with pipes and equipment.

Also, although the Eddy mimics the work of a water softener it does not alter the total dissolved solids (TDS) of water. This means that the healthy mineral content of water is preserved.

Minerals such as calcium and magnesium, which are good for us but harmful to equipment, remain in the water but do not cause limescale in the house. This is achieved through the use of electromagnetism.

This article will help you clarify if the Eddy is right for you.

Do Electronic Water Softeners Work?

It is important to know that hard minerals (magnesium, calcium etc.) are not removed from the water.

These minerals are problems for pipes and plumbing fixtures because they produce limescale but are healthy for us to drink. By changing the chemical state of minerals and not just removing these minerals, the Eddy system does a smart job.

Although the water is not really softened. It still has the same property of soft water as it does not lead to calcification. However, if tested with a water hardness kit, it would have exactly the same composition as hard water.

How The Eddy Works

Although the Eddy water softener is advertised as a water softener, it has some important features.

What is unique here is the fact that it is indeed an electronic device and not a cassette (even though it looks like one).

Optimh20 Whol House FilterThe machine has spools that will wrap around your pipes and plumbings.

It creates an electromagnetic wave that interacts with water. This magnetic field passes through its inflowing water. Its main objective is to prevent lime from sticking in the pipes.

The system is fully electronic and works with a 110 volt power supply. The power consumption is minimal and works at only 5 watts. If you consider that the average light bulb has a power of 40 watts, you can see that the Eddy is very energy efficient.

This system is virtually maintenance free. There’s nothing to clean or change, and I would only recommend checking to see if the lights are on, especially after a power outage.

What Does The Eddy Eliminate?

The short answer is nothing. The Eddy Electronic Water Descaler doesn’t remove or add anything to your water.

In fact, the number or amount of TDS in your water will not change. The product never interacts directly with water, since everything happens in the electromagnetic field.

The water that results will mimic softened water, but essentially nothing is introduced into your taps and pipes. Also, nothing useful is taken out of the water. No salt added. For example, calcium and magnesium remain intact.

The Contents Of The Set

Well, the content of the set is quite simple here. You will receive the box with the Eddy water softener, 4 cables and a power supply is also included.

No plumber is required for the installation as no changes are made to the piping.

It comes with no tube is disconnected as you only connect the machine, place it on the wall or leave it to rest somewhere.

Be sure to wind the wires properly around the tube.

The set has no keys or nails.

You only need the mounting brackets to get started. This is an important note. Never mount the device outdoors. It is not waterproof and 100% electric. It not only works badly but also poses a fire hazard if it gets wet during operation.

Installation of Electronic Water Softener

One of the biggest advantages of this type of water softener is the repair / replacement guarantee is for life.

Yes, the company does not even bother giving you 5 or 10 year warranty as they expect this to be a life-long product.

In addition to this, you also receive a 12-month money-back guarantee.

The other big advantage of this system is how easy it is to maintain and install. Almost anyone can do it as shown in the video below.

Eddy Water Descaler – #ad

** 2 Week Update (The ONLY follow up to this video so far) **

Eddy Water Descaler UPDATE

“2 Week Update (thanks for asking Tony) We cleaned up the water spots in our sinks and fixtures after the install and noticed pretty much right away that the water spots were much “softer” and seem to accumulate less as the water runs off of the side of the sinks better. However, we did have iron streaks reappear in the stool in a few days time. This is partially due to my toilet leaking through a tiny amount of water into the bowl between flushes but we were hoping that the iron would be prevented from sticking. Like I said though Eddy does not claim that this will prevent iron stains. I’ll give it some more time but due to the iron in our water we may need to still add a water softener at some point if we don’t find a solution to the iron in the toilet problem. I’ll update again in the future. Thanks guys.”

Eddy Magnetic Water Descaler

The Eddy Electronic Descaler is a very attractive proposal for three main reasons:

1. It is much cheaper than a conventional water softener.
2. You don’t need to use salt for it to work.
3. Doesn’t need constant monitoring and it’s easier to set up.

First we deal with the money. The suggested retail price is small compared to what you could pay for a quality water softener. In addition, the regenerating water does not become waste water as is the case with a salt water softener. The result of this is lower water bills and you don’t need to spend money on expensive softener salt. Therefore, in terms of money, it easily surpasses traditional water softeners.

Not using salt means you get to save money, but there is another reason why you want to use an unsalted alternative.

Salt is actually considered a pollutant when it is released into the environment, and chloride (Cl-) is dangerous to aquatic life and crops.

When water softeners dispose of salt water from the drain during the regeneration process, they increase the pressure on the local environment. So, to be more ecological use salt-free alternatives.

Eddy Electronic Water Descaler WORTH It?

Maybe. Mainly if you’re on a tight budget.

If you have medium to hard water then you need to get a water softener as the Eddy won’t make much difference. Or you can opt for a more POWERFUL sand EFFECTIVE salt free softener like Simplysoft Whole House From Aquasana.Mr Water Geek Thinking

The Eddy Electronic Water Descaler uses electromagnetism to reduce the negative effects of certain elements in hard water.

Electromagnetic waves are transmitted by water directed to the salts of calcium, magnesium and manganese.

These elements form what we know as “cal.” Electromagnetic waves change the shape of these magnesium and calcium crystals and make them more soluble.Aquasana SimplySoft

This makes tubes, taps, boilers, and appliances in your home less likely to suffer from hard water.

Preventing these crystals from interacting with their environment reduces the risk of limescale.

Get a water softener if you have = hard water levels OVER 25 PPM

This water is very hard and you have a lot of problems with limescale in your kettle and hard white stains all over your pipes and plumbing.mrwatergeek winner badge

You can consider getting a water descaler/conditioner = hard water levels UP to 25 PPM

This means your hard water is low to medium. You don’t have too many or aggressive limescale but simply want to protect your appliances, plumbing and pipes.See customer reviews

  1. Happened to look at my Eddy today…it had about 3/4” of water in it…how can that be??? I unplugged it and it will be headed for the trash. Not impressed at all

  2. Hello.

    As I am a tenant, I am rather looking for solutions which does not involve me paying a big and expensive installation that will be left behind when I will leave my flat, therefore the Eddy configuration would come handy here. However I read that it doesn’t work above 20 GPG but rather shows the best results at 10 GPG and under. The water in my area is at 15 GPG, would you think it worth it or I should go for something that will shows better results even though it might be left behind? Also at 15 GPG would it prevent limescale building up in my kettle or not really?

    Kind regards

    1. Hi GK

      My understanding is that the Eddy is only effective at lower levels of GPG and even then I’m still skeptical because I’ve seen so many mixed reviews.

      Stay hydrated,

  3. Hi a year and ahalf after installing the Eddie we still have water stains and a new problem white chunky goop that builds up under the toilet rim as this is a new problem I think its the Eddie our pipes are clean now our toilet is getting the residule left over from the pipes this stuff is as big as half your thumb and like a pastey caulk

  4. I was wondering if there was any downside to installing the Eddy descaler after my well pump and then a water softener. Will the Eddy interfere with the softener’s job? I would be using a standard salt-based softener.

    1. Hi Tim

      I doubt that very much because the Eddy temporarily changes the structure of your water so that the “hard water minerals” don’t stick to your pipes – at least this is what it’s supposed to do in theory.

      However, if you are already getting a salt-based softener then I don’t think you need the Eddy because the softener will deal with the hard water much more conclusively?

      Stay hydrated,

  5. Hi
    I’ve heard these things have a limited range in piping. If I was to install this, I would imagine it would be right at the water entrance to my house. What would the effects be in my hot water heater? Would I need to install another one downstream of the water heater?

    1. Hi Mike

      I don’t think the Eddy will do anything significant to your heater except reduce the scale buildup. If this is what you want then installing it closer to the heater where it can be more effective makes the most sense.

      However, this is just my guess. Shoot the company an email and see if they can clarify further

      I would love it if you could get back to me and let me know how you got on so I can update my own knowledge in this area.

      Stay hydrated,

    1. Hi Dave

      Not really because the descaler doesn’t remove anything from your water it supposedly “re-conditions” the water so you stop experiencing things like limescale.

      So perhaps use limescale remover before you install your new device and see if the limescale returns to know if the descaler works.

      Stay hydrated,

    1. Hi Sher

      Yes you can.

      You can install the Aquasana at the mains supply and then install the Eddy at another point of the entry pipe. However, Aquasana by itself can treat hard water up to 24 GPG (Grains Per Gallons), which is very hard. It will also filter your water and make it safe to drink by itself unlike the Eddy.

      Let me know if you need any further help.

      Stay hydrated,

  6. Does the Eddy and other water Descalers change the Ph of the water? Are there any known human health effects to drinking this magnetized ionized water? I want to be careful about the solution we choose because this is what we drink and bathe in! We are at about 9 GPG. Thanks!

    1. Hi Lydia

      Descalers don’t change the make up of your water, they simply move the minerals around so they act differently. They don’t filter, soften, or change the pH of your water. This means that if you already have high pH water then you will still have high pH water after installing a descaler.

      If you want healthier water for drinking and bathing in then you should really add on a water filter to the descaler. Aquasana is the best at allowing you to add on filters and other water treatment options to a salt free water “softener” descaler.

      Best wishes,
