What to Look for When Buying Electronic Water Descalers

Some people might think that buying the best electronic water descaler is a breeze after learning about the product’s fundamental components. While this may be true, some people might still be confused about which product to choose from a sea of selection. Here are several water descaler factors prospective buyers must consider.

People have two choices for a water descaler, although a third technology is gaining momentum.

• Electromagnetic

An electromagnetic water descaler is the most common type people can buy in the market. These products produce an electromagnetic field that modifies the shape of carbonate crystals, preventing their adhesion onto plumbing surfaces. Electromagnetic devices are inexpensive but may have insufficient coverage for a large house.

• Capacitive

Capacitive descalers also produce an electromagnetic field like EM devices. However, these products feature an advanced capacitor to deliver electric current to its wires.

One advantage of this system is its hard water effectiveness, handling any calcium and magnesium carbonate level. Unfortunately, capacitive descalers can cost at least twice more than an ordinary electromagnetic descaler.

• Electric Impulse

An electric impulse water descaler works to modify hard mineral composition instead of creating an electromagnetic field to disrupt carbonate chemistry. The alteration prevents carbonate compounds from adhering onto surfaces, eliminating scale buildup.

Because it is a new technology, one can expect these products to be more expensive than electromagnetic and capacitive descalers.

It would be best to understand that descalers do not remove hard minerals such as magnesium and calcium carbonate. Instead, these products prevent carbonate adhesion onto surfaces to eliminate scale formation.

One way to determine a product’s descaling effectiveness is its grains per gallon (GPG) rating. Capacitive descalers have the upper hand on this matter because they are limitless. On the other hand, electromagnetic descalers cap their descaling efficiency to 25 GPG. However, some advanced units can go up to 35 GPG.

Elementary physics dictates that electromagnetism only works with metal objects. Hence, people assume that electromagnetic descalers only work with steel and iron pipes. However, many products today are also compatible with plastics, including PVC and PEX. It would be best to check pipe material compatibility before buying.

Electric water descalers draw their power from an electric source, most often an electrical outlet. That is why many products are for indoor use only. The good news is that some manufacturers design their water descalers with exceptional weatherproofing.

Buyers who want to install these products outdoors must look for their ingress protection rating. It should be at least IP65.

It is one thing to read comprehensive smart descaler reviews and a different matter listening to real people’s experiences. While customer reviews can be biased, consumer opinions enable a prospective buyer to form a clear picture of how the water descaler works in real life.

It would be best to go through each customer review to understand consumer sentiment about the water descaler. Recurring issues often present themselves, serving as red flags for the buyer.

Most electronic water descaler manufacturers guarantee their products up to 12 months, although a few can extend the warranty period to five years or longer.

Unfortunately, some companies also do not cover their water descalers for any defects. It would be best to check customer reviews to evaluate how the company honors its warranty commitments.

A product with an extended warranty tells buyers two things. First, the company vouches for the product’s high-quality construction and performance. Second, it implies durability.

In general, water descalers are more affordable than conventional water softeners. However, there is a substantial price difference among the various water descaler types. Electromagnetic units are the least expensive, while capacitive and electric impulse devices are the priciest.

One must also consider the warranty in the price equation. Low-priced products typically do not have guarantees, and there is a chance they might not last very long. These options require early replacement, which can increase the overall cost.

Do Electronic Water Descalers Really Work

Yes, electronic water descalers work but not as effectively as water softeners. It is also the answer people get when asking, do magnetic water descalers work?

Limescale formation (scaling) results from the adhesion of calcium ions onto plumbing surfaces. Electronic water descalers prevent ionic surface adhesion, eliminating limescale formation.

Most electric water descalers have a box and a pair of wires that people wrap around the main water pipe. If one remembers his elementary physics class, wrapping electric wires around a metal rod and running electricity can produce electromagnetism.

The resulting electromagnetic field rearranges the calcium ions in the water, clumping them together to produce larger calcium crystals with fewer free ions. The result makes the calcium compounds less likely to adhere to the inside surfaces of plumbing and water fixtures.

Calcium and other hard minerals remain in the water. That is why most people can still taste and smell these compounds in their water.

It is essential to understand that descalers only change hard minerals’ ability to adhere to surfaces, not remove them from the water.

Where Do You Put an Electronic Water Descaler

Many electronic water descaler manufacturers recommend installing their products as a point-of-entry device – meaning, one must set up the device anywhere along the house’s main waterline.

However, some companies advertise their products as a point-of-use water descaler, requiring installation near faucets or fixtures the homeowner wants to prevent limescale from forming. Most of these products have a short-range electromagnetic field.

Regardless of where the homeowner decides to install the water descaler, it must be near an electric outlet. These products require electricity to create an electromagnetic field, preventing calcium surface adhesion.

How Do You Install an Electronic Water Descaler

Many electronic descaler reviews highlight the system’s installation ease as one of its most significant advantages. There are no storage tanks to fret about or messy plumbing works.

An electronic water softener or conditioner (as descalers are sometimes called) only includes three fundamental components. There is a box-like contraption that delivers an electrical current through the wires wrapped around the waterline. The device has a power cord for connecting to an electrical outlet.

Installing a water descaler is a cinch, and one can get this system up and running in minutes. One must read the manufacturer’s installation instructions for a hassle-free set-up. Nevertheless, the following steps highlight the product’s installation ease.

Water Softener Vs Descaler: What’s the Difference

The principal difference between a water softener and a descaler is their impact on calcium and other hard minerals. A water softener removes these compounds, resulting in close to zero water hardness minerals.

On the other hand, a descaler only changes the hard water minerals’ chemical characteristics to prevent surface adhesion and limescale formation. Testing the descaled water will reveal that the grains per gallon (GPG) results are similar to regular water.

The good news is that one can drink calcium, magnesium, and other minerals for improved health. Families also do not need to fret over limescale in their fixtures and water appliances.

Examining the various electronic water descaler pros and cons reveals that this product’s principal advantages are affordability and ease of installation. These products cannot have a simpler design: an electronic box, two wires, and a power cord.

If you have a DIY spirit, you can build your own electronic descaler. All you need is a device capable of producing low-voltage current and a pair of electric wires to loop around the water pipe.

Conversely, water softeners may require professional installation. They require modification of the existing plumbing to accommodate the ion-exchange media tank and the brine tank. In some cases, water softener installation might also call for a sediment pre-filter.

Conclusion

The best electronic water descaler saves families from costly plumbing repairs due to limescale buildup. It also safeguards water fixture and appliance integrity, enabling households to enjoy scale-free water. Moreover, people do not get rid of beneficial minerals in the water, consuming them in their drinks or food for better health.

Unfortunately, choosing the right electronic descaler can be daunting for some. That is why one must be cautious and methodical in researching the best unit to bring home.
