Review: 100 plus year old well water - This might be different unscientific take. These pics show my Airsense Cpap and the water by it or in it. Usually because my cpap requires distilled water, my well water here clouds up in one night in the humidifier and the heater pad is solid white. It's been well over a week without cleaning the chamber and look at the water. Still water and not a cloud. My refill glass is also 2 days old and no hardness. That's pretty good results and proof enough when you can go from every day cleaning to every other week or so..Pretty impressive for a 120 plus year old well and a easy to install device put in after my 5 micron sediment membrane. I researched and that was the most optimal for my really old house and well. Love it so far.
Review: Don't believe the nay-sayers, I was skeptical but it worked - I was very skeptical this would work but thought I would give it a shot for the ease of installation and the cost. Prior to purchasing I read many reviews stating that these devices scientifically can't work and that they are just a scam. Well, I can confidently say that these nay-sayers were wrong even though they sounded very credible in their reviews. About 2 years ago my wife and I moved into a house on its own well, with all original plumbing since it was built in 1992. The water from the well was tested to be good when we bought the house and the previous owners raved about how good the water tasted, we agreed after drinking it. Although the water tasted great, it definitely had a lot of minerals in that caused a great amount of build up on all the faucets and also in the drains, causing flow issues. Even after we replaced the shower heads and remodeled the kitchen we had white mineral build-up within a month on the new shower heads and faucets, plugging the small spray holes and disrupting the flow. After installing this device I instantly noticed an improvement of the water feeling softer in when showering and washing dishes. It definitely lathers better and leaves your skin feeling less dried out. We have had salt water softeners in the past and it made the water feel very similar. After a few days it cleared out all the newer faucets/shower heads and started to break down the build up on the older original faucets. It even caused a leak in the the drain plumbing under one of the sinks because it broke down the mineral build up in the drain around one of the old seals (I was able to fix it by just taking out the sink drain and trap, cleaning it, and just reinstalling it). Additionally, the dishwasher is not leaving spots anymore and the stainless steel sinks have less spots. After a about week we've noticed all faucets are flowing better and and the old fixtures from 1992 are shedding lots of mineral build up. We can now delay replacing them until we do the bathroom remodels we have planned for the future. The kitchen faucets now spray as they are intended to without any plugged holes. We originally installed this device with the hope of cleaning out the mineral deposits in our plumbing that has built up over the years and hopefully restore some water pressure, and after the results I have already seen I am confident that this will accomplish that. Even though the device does not remove the minerals like a salt softener it definitely descales pipes and improves the quality of the water for our use. DON'T BELIEVE the people that say its a scam or the guys who says he's an electrical engineer and his wife has a few chemistry degrees and call it a pseudoscience scam. The proof is in the results! The only regret I have is not getting the next bigger model that is rated at pipe sizes larger than 1". I assumed my pipe feeding my pressure tank was only 1" but realized it was 1 1/4" when I went to install it. Instead of returning it for the larger one, I just installed it after the pressure tank where the pipe is smaller because I didn't want to spend any more money and I was very skeptical of it working anyway. Unfortunately I won't be able to descale the water going into the pressure tank unless I buy the CWD30, I may end up buying one later on since I am now a believer! Don't be afraid to buy this product this if your goal is to descale your pipes/fixtures, it will do that. Hopefully it will also improve your the quality of your water as it did mine. I typically don't leave reviews like this, but I would have appreciated a review like this when I was researching this product. I hope it can help someone else!

## 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.

### ⭐ This System Does Not Work!
*by S***E on July 15, 2025*

Why did you pick this product vs others?: At the end of 2019 I moved into my newly remodeled condo. I had heard about these electronic devices where you wrap wires around the incoming water pipe to make the water soft. At the time I thought this was a great idea to enjoy soft water without having to buy salt for a softener. Plus this option was less expensive than buying a complete soft water system. So I spent $350 and bought this unit. I installed it correctly. I used it for several years but hard water marks always built up on both my kitchen sink and bathroom sink. I was constantly having to clean it off. Then one day my shower head started making a singing noise. Then my toilet started doing the same thing. At this point I knew I was in trouble with my plumbing. Hard water buildup was causing this singing noise to come from both appliances. So the bottom line is - this device was doing absolutely nothing to soften my water! I ended up throwing this electronic de-scaler system in the garbage. Then I bought a real soft water system that uses softener salt and I have absolutely loved it! I no longer have hard water marks on both my kitchen sink and bathroom sink. So my advice is do not waste your money by buying this system but buy a real soft water system instead that works!
