Review: We have had the Yarna CWD24 Water Descaler installed for about a few months now and have noticed a large decrease in the amount of sediment in our water kettle. It is a clear glass kettle and had deposits that had to be scraped off before. Now, there are still some noticeable white chalky sediments, but they wipe off with a paper towel. The longer the unit is installed, less sediment is showing. Also have noted the water in the shower feels softer. Spring especially gave us an odor with our well water and that has really gone away too. Very happy with these easy changes. Looks like it will keep improving our water as time goes on with the unit installed as we have an older home with older pipes. Installation was simple. Have tape handy to hold down the ends if you are installing alone! Very happy with this very affordable purchase and its effectiveness.

## Features

- HOW IT WORKS: Yarna CWD24 is a Patented alternative water softner for homes that treats water with electric pulses generated within the electronic unit and controlled by a micro-chip! These pulses are transmitted via our Ultra Flat Impulse Bands which breakdown crystals that would otherwise buildup into limescale, which can break appliances.
- WHO BENEFITS FROM YARNA: Our customers report cleaner pipes and faucets, lower costs for descaling and heating, and better overall water quality using our whole house water softener system alternative. Depending on the current condition of your plumbing, it may take up to three months to observe a significant improvement
- EASY INSTALLATION: All you need is access to a minimum of 10" of free pipe space with a maximum pipe diameter of 1". Yarna whole house water descaler is completely DIY with no need for any tools or specialized help. Our whole house water descaler works with any type of piping up to 1" thick
- WHY DESCALING IS BETTER THAN SOFTENING: The Yarna CWD24 water softener descaling system won't eliminate beneficial minerals from water. Additionally, unlike traditional whole house water softeners, Yarna does not require the use of salt and does not allow water to be wasted

## Questions & Answers

**Q: I have read that this process conditions the water and that it only looses its scaling properties for some time (72hrs?.  Is this true of your device?**
A: Yes. Water sitting in a container after it has been treated by our product will revert back to the original state in 2-7 days depending on the temperature, the warmer the better.

**Q: Why is your product more expensive than the rest? How is this different?**
A: That is a very good question, not all descalers are created alike, or function the same way. So let’s go through some aspects:
 
-       Basic operating principle: the Yarna uses a capacitive effect. Most other products have electro-magnetic or simply magnetic effects. The capacitive technology is far more effective and here is why. The two wires together with the water form a capacitor. The role of a capacitor is to store and release energy. The capacitive technology always uses water to its own advantage. Compared to capacitive, the EM effect always struggles to penetrate the pipes and water. So you need a much higher energy to generate a strong enough EM field. Small devices with 12V power supplies just can’t deliver that.  Having the water inside the pipes as our ally and courier, we are able to deliver all the energy right where it is needed (at the Calcium and Magnesium) 
-       Frequency of the impulses: depending on the water speed you need a different frequency of the impulses that are discharged. Some other devices take this into account also, however only somewhat. We have the largest range, from 3 to 33kHz, more than enough for all scenarios. Our device will be effective from the slightest drip to 20 gallons per minute.
-       Works with any grain per gallon: to our knowledge this is the only device that can do that. Because we can deliver plenty of energy and we have the variable frequency we can successfully treat any hardness. The only condition is imposed by the max 2” pipe diameter.
-       Emphasis on quality: every component, from the aluminum enclosure to the active impulse bands to even the zip ties are high quality and built to last. 
 
Also regarding the price, our device is actually very affordable compared to other devices with similar technologies. Similar products range from $500 to $1500, with comparable specifications. We tried to implement the same technology in a much more affordable package so that anyone could install one in their home.

**Q: Any benefit to installing a second unit before our water softener that is in need of descaling?**
A: Thank you for your question!

If you are referring to installing 2 water descalers, then the answer would be, you will need one per household.

It will also depend on your water softener because If you have a salt-based water softener, our product is redundant. And the same is true if you have a Yarna installed, and here is why. Consider the following scenarios:

1. The Salt Water Softener is installed first. When the water hits the softener it will retain calcium (the main component of limescale) and release salt instead. This system will pull out most if not all the calcium and replace it with salt. The Yarn Descaler installed after the saltwater system won’t have anything to act upon. In our opinion salt in the water means trading one nasty side effect for another. Excess salt is highly corrosive and not so good for the body.
2. The YARNA Descaler is installed first. The water reaches the installation point and the electric field converts the calcium into a different form of calcium that will not adhere to anything (the pipes, appliances, etc). You still have calcium and magnesium in the water. Generally, calcium in the water is considered healthy. However, you eliminate all the negative side effects that the untreated minerals have on the pipes. Also, in this case, the now treated calcium (although harmless) will enter the saltwater softener and the same replacement process takes place. You’ll end up with salt in the water.

This is why our recommendation is to chose one of them and NOT have both working. Depending on what you want/need I strongly suggest installing only one of the two. If you want no minerals in the water then salt systems are the way to go. If you want to eliminate the nasty side-effects of calcium, Yarna will do that.

But if you are using a non-salt water softener then you can install our Water Descaler before it. 

I hope that answered your question.

**Q: Does it help get rid of ferrous iron ?**
A: No, just calcium carbonate and magnesium carbonate. And just to be clear, it doesn't get rid of them, they are still in the water but they don't 'stick' to glass doors, dishes, or the insides of pipes.

*by T***R on 1 September 2022*

There are a TON of reviews on this and by and large here is mine: - Simple to install, in fact it seems almost to easy but it just is - Has reduced the hard water spotting we used to have on the chrome fixtures (not eliminate them) - Water is NOT softer, which is what they tell you. It will smooth out the structure of the mineral so it will reduce the buildup and that is the goal with this device - I didn't want a salt brine to have to deal with nor the big bags of salt and the added expense of installation - Other users, at least 94% + like the system and of course there are those who have tried it and for some reason didn't work, but the percentage is simply too high to not give it a try. - Our home is central Canada, very hard water (and added nasty chemicals), so this was installed to help add life to our hot water system and reduce the mineral deposits on the fixtures, mission accomplished there. Cons: - Power cord could be longer, perhaps a 10' cord as it's super light and takes up little space in the package
