People have been searching for an alternative to salt-based water softeners for years. Lugging around bags of salt can be a pain, and having to worry about salt levels constantly does not leave you peace of mind that your softener will be in peak shape.

Best Electronic Water Descaler

Additionally, salt-based water softeners take up TONS of space and can be pricy to install and maintain. Luckily, with the evolution of the electronic water descaler, these issues are a thing of the past. Using electromagnetic waves rather than salt, an electronic water descaler will not remove unwanted particles but rather suspend them in the water to keep them from reaching your pipes and glasses.

Electronic water descalers are becoming more and more popular with people all over the globe because of their maintenance-free nature, affordability, and easy installation. There are so few moving parts with electronic water descalers that any homeowner or landlord could install it with little to no resistance.

All you need is a standard 110-volt electrical supply, and you will be able to have cleaner, more pure water throughout your home. There are several choices to choose from when deciding on the best electronic water descaler, but with our in-depth review section and buying guide, we are confident we can help you find the perfect choice for you.

How Do Electronic Water Descalers Work?

The science and technology behind electronic water descalers are super cool. The biggest difference between salt-based softeners and other alternatives is that descalers do NOT remove anything from the water.

Softeners will remove particles and contaminants from the water using a filtering agent like salt or resin. Electronic water descalers will change the molecular structure of the water without removing anything. This helps the water flow freely and does not allow water molecules to stick to each other and cause scale build-up.

Electronic water descalers use a combination of electricity and cable/metal bands to create the force that changes the water’s molecular structure.

The cable or metal bands that are wrapped around the main water supply pipe will create an electromagnetic wave that stops hardness particles and rearranges them. This allows the water to come through the pipes and into appliances in the best molecular structure for your pipes and appliances.

4. Capacitive Electronic Water Descaler System

Capacitive Electronic Water Descaler

The Yarna CWD24 electronic descaler is one of the unique systems that we have investigated thus far. Rather than the typical electromagnetic field that most electronic water descalers use, this system uses the water flow to its advantage by using the water flow’s energy.

Because the bands are so much larger than most comparable systems, you are getting more energy dispersed in a larger surface area, allowing more areas for hardness particles to be trapped.

One of the biggest advantages of choosing this system is handling any amount of water and any level of hardness. Because the metal bands are so wide, you do not need to worry about the distance between your descaler and your water inlet.

This device can manage the water for 20 apartments and effectively remove hardness particles and save your appliances from scale buildup for years.

How to Install the Eddy Electronic Water Descaler

The beauty of an electronic water descaler is the ease of installation. It requires virtually zero plumbing experience or really any experience with home improvement products.

An important factor that is regularly overlooked is where is the best place to install the water descaler. Before you purchase it, ensure that there is an outlet (standard 120-volt) somewhere near the water main. Ensure that the electronic water descaler you choose has a long enough power chord to reach the pipe from the wall outlet.

Once you have scouted the perfect place to install the descaler, the installation can occur.

This is a very quick process and one that will have you feeling accomplished when completed. After plugging the switchboard into the wall, it is now time to place the metal cable bands onto the main water pipe.

According to the instructions that come with the unit, carefully wrap the band around the pipe, leaving a tiny bit of room between each wrap. Work your way from inside to outside with cable bands and wrap them tightly onto the main water line.

Repeat the same process for the other cable band are ensure they are connected to the switchboard. From here, the electromagnetic wave that the cable bands create in correlation with the power supply will do all the work.
