Electronic Water Descaler Buyer’s Guide: Key Factors
If you are looking to purchase a new electronic water descaler, we will cover all the key decision-making factors you need to know below.
How Do Electronic Water Descalers Work?
Electronic water descaler conditioner work by using a process called electrolysis to break down the molecules of limescale. This prevents the lime scale from building up and causing problems. The electronic water descaler installs in under 20 minutes and requires no maintenance. Simply mount the unit to the wall or pipe, and wrap the descaler cables around your water source pipe, then plug the unit in – that’s it! They also require very little energy usage so it will save you money on energy bills, cleaning and repairing your appliances.
How does a water descaler work:
- Hard water contains high levels of calcium and magnesium.
- These minerals build up on pipes and fixtures, causing a variety of problems such as reduced water flow, decreased efficiency of appliances, and higher energy bills.
- Electronic water descalers use electrolysis to break down the molecules of limescale as water passes through the plumbing that has the descaler wires wrapped around it, preventing them from bonding to pipes and fixtures.
- This allows the water to flow freely and prevents the buildup of limescale, and actually removes existing scale on your fixtures.
- The electronic water descaler is easy to install and requires no maintenance. It is also very cost-effective, as it will save you money on cleaning and repairing your appliances.
Types of Electronic Descalers
There are two types of electronic descalers:
Electromagnetic water Descalers
These devices attach to your water supply and create an electromagnetic field that breaks up the minerals in the water, preventing them from attaching to surfaces and creating build-up.
In addition to preventing hard water spots, electromagnetic water descalers can also improve the taste of your water and extend the life of your appliances by preventing mineral build-up. If you’re looking for a way to improve the quality of your home’s water, an electromagnetic water descaler may be the answer.
Capacitive Electronic water Descalers
Capacitive electronic water descaler system work by sending out electromagnetic waves that create a magnetic field. This field helps to break down the bond between the water molecules and the minerals, preventing the formation of the new scales.
In addition, descalers can also help to remove existing scale from pipes and other surfaces. By using a capacitive electronic water descaler, you can help to keep your water-based system running smoothly and efficiently.
Benefits of Electronic Water Descalers
When it comes to the benefits of electronic water descalers, there are many. Here are just a few:
- Reduces Scale: During the process of electrolysis, the water descaler emits electromagnetic waves that help to break down the bond between the water molecules and minerals. This prevents the formation of new scales and helps to remove existing scales from pipes and other surfaces.
- Lower Price Point: When compared to traditional methods of descaling, such as chemical treatments or mechanical abrasion, electronic water descalers are much more affordable.
- Easy Installation: Most electronic water descalers can be easily installed by anyone with basic DIY skills in 15 minutes.
- No Maintenance: Once installed, there is no need for regular maintenance or upkeep. Simply plug in the unit and let it do its job.
What to Look for When Buying an Electronic Water Descaler?
When shopping for an electronic water descaler, there are a few things you’ll want to keep in mind. Here are a few factors to consider:
The Type of System
There are two main types of electronic water descalers: electromagnetic and capacitive. Each type has its own advantages and disadvantages, so it’s important to choose the right one for your needs.
The Size Of The Unit
Make sure to choose a unit that is the right size for your home or business. If you have a small space, a lower capacity unit may be all you need, or you can even consider a portable water softener. For larger spaces, however, you’ll want to choose a larger, more powerful unit like the Yarna or Scalewatcher.
Your Home’s Water Hardness
The hardness of your water will play a role in how effective the descaler is. You will first want to test how hard your water is. If you have very hard water, you’ll want to choose a descaler that is appropriate for your specifications.
Some units require professional installation depending on where you need to locate the unit, while others can be easily installed by anyone with basic DIY skills. Be sure to choose a unit that can be installed easily and without the need for special tools or skills.
Water Flow Rate
The water flow rate is the amount of water that can be treated in a given period of time. If you have a high water flow rate, you’ll want to choose a unit that can handle the amount of water you’re using.
Most units come with a warranty of at least one year. However, some companies offer longer warranties for an additional cost. If you’re concerned about the longevity of the unit, choose a model with a longer warranty period.
Frequently Asked Questions
Do electronic water descalers actually work?
Yes, water descalers do indeed work with hard water and scale buildup. However, they use a different process vs. water softeners. Water descalers don’t actually “soften” the water, so although the hardness ions are still present, they will not stick to your plumbing and appliances.
What’s the difference between a salt-free water softener vs a water descaler?
There are several differences between a water descaler vs salt-free softener. Of course, there is the size and simplicity factor. Water descalers take up almost no room, and cost very little vs a salt free-water softener. Functionally, neither option actually removes hard water minerals like an ion exchange softener. They both condition the water’s minerals composition so that it wont cause scale buildup.
To learn more about salt-free softeners, read our best salt-free softener guide here.
How much does an electronic water conditioner cost?
Water descalers range from a little over $100 to over $500. It depends on the water hardness and size of your home or RV for how powerful you will need the unit to be.
Can I use an electronic descaler with well water?
Yes, water descalers can work with well water. Since well water is typically much harder than municipal water, you will want a more powerful unit like the Yarna to get the results you’re looking for.
However, if your well water has heavy sediment or iron, it is advisable to get a water softener designed for well water.
How effective are electronic descalers?
There are mixed messages about water descalers out there. Water descalers are effective at altering the water composition to reduce and remove scale buildup with hard water. You need to be sure you are getting the appropriate model that is strong enough for your particualal needs. For the price and efficiency, water descalers are great. That said, they are not AS effective as a whole house salt-free water softener or ion exchange softener system.
How do I install an electronic descaler system?
Installing a descaler system takes only 15 minutes from start to finish. Simply mount the electronic descaler module within close proximity to your water supply line. Then wrap the included cables around the plumbing, keeping it in a tight coil formation. Once the system is mounted and installed, all you need to do is plug it in and you are ready to start reducing scale buildup!
If you’re looking for a way to improve the quality of your home’s water, an electronic water descaler may be the answer. By using a unit, you can help to reduce scale, extend the life of your appliances, and improve the taste of your water.
When shopping for a unit, be sure to keep in mind the type of system, the size of the unit, your home’s water hardness, and the installation process. By taking these factors into account, you can be sure to choose the best electronic water descaler for your needs.
