Electronic Water Descaler Review - Yarna Water Softener 

Yarna Water Descaler (CWD24) ....................... amzn.to/31M7j58

So, a guy spends his time and energy trying to show an honest review using POV. Like most of us do. We look and feel, like he did. He never said it would be a scientific test, like they do in laboratories. People come and complain instead thanking the person for the time spent. If you didn't like it, a good idea would be, make a review yourself, easy. As for me, I'm thankful for the time shared.

Water flow test isn't taking into account for inlet pressure changes. Ppm test isn't taking into account for filters at varying stages of life cycle. Overall good video!

You need an iron removal system ahead of the softener that uses NS mix, google that up. As for the filter. Look for a spin down filter with reusable filter. Just take out the filter soak it in iron out and put it back in. I've been using the same 2 filters for 11 years and there still good.

Had it for a year now. Almost zero rust in my water, so that's not a factor. Not sure about the overall health of dishwasher and water heater, but there's a significant reduction in shower and toilet scaling. Not sure about my aquarium. Still seems to leave buildup when the water evaporates but not sure if it's less bad. Overall, I'm pleased. I think people have to be sure they're managing their expectations based on what it says it's capable of and what it's not.

Great review and information. I recently did an unboxing review and initial install. I'll be linking viewers to your video so they can take a deeper dive on how well it works.

It's great that this guy tries to make an unbiased test which is a lot more than what professional reviewers do. But, there is one big criticism. His data on limescale buildup is based upon personal observation is a big no-no with scientific studies because human perception is easily manipulated unknowingly. Just to let you know, scientific research has shown that electronic and magnetic descalers have NO effect. These companies should be sued for selling stuff that's completely fake.

Seems this would be best applied right before the laundry washer and dishwasher and shower. It helps make more suds to clean by reducing water tension the same as soap does from what I've observed and the water loses the effect several feet after. Don't know if it is significant enough to protect a water heaters elements from buildup. I doubt it does much for that. It has more like a temporary micro aggitation effect on the water which goes away rather quickly the farther away from the source.

velcro strips would be better I would think at holding those strips down to the pipe. Excellent video and follow threw thank you for the info!!

A Greensand filter should make the biggest improvement for your rust

Your well pump, unless its a constant pressure system, fluctuates with the pressure switch settings. The swing can be anywhere from 10 to 20 psi. Its impossible to get consistent GPM measurements with a bucket unless you are doing the measurement after each time the pump stops cycling. These descalers ( electronic conditioners) do absolutely nothing for rust. Given the high amount of iron in your water, your water softener resin is more than likely clogged with rust. and is working very inefficiently. Water softener are not designed to deal with large amounts of iron in your water. You need a filter system designed for iron removal like green sand or an air pocket oxidizing filter with an oxidizing media placed before the softener . TDS will not improve with an electronic conditioner as it does not remove any dissolved solids from the water which is consistent with your results. The only thing the electronic conditioners are good for is limescale buildup from hard water and calcium, even then they are no where as good as a salt based water softener. I would get your resin changed in the softener or try running a cycle with iron out in brine well to try and clean the resin bed. Also I would run a product like ResCare with the auto drip system into the softener to keep the resin from fouling up with iron. Great review of the Descaler.

I’ve had a similar product. If you have one at every faucet, it might help keep the particles suspended, but they really are just a placebo. Your water softener and filters should be knocking out the rust and mineral deposits. If you still have issues after your system you need to upgrade or get a larger system.

Thank you for your insights. They really helped. I had no trouble hearing you. It seems that the device does some help but not like a salt-based water softener. I will keep looking and hoping that science comes up with something more definitive and doable. I have a septic tank and can't do the salt stuff.

Thanks brother for your conclusion and hard effort towards it. This system may not be suitable for you requirement as there is more iron content in your water sample as per your feedback, but this system is built to work effectively on Cacium and magnesium hardness in water. Once again thanks for your effort

Based on a quote found on this video, wouldn't it make sense to put a spin down flushable water filter after the descaler to then filter out the water crystals that were formed by the descaler. Assuming the crystals are big enough. This then would have the effect of softening your water and dramatically reducing the TDS measurement. Here is the quote I base this statement on: OK - very simply, what the magnetic field does is that it causes the calcium carbonate to deposit as aragonite rather than calcite. As this tends to nucleate and grow in the water rather than on the pipe surface the solids just wash through. I did some extensive work on this decades ago for my company using two identical electrically heated hot water tanks , one with permnanet magnets on the inlet pipe - the other without. Water was heated and held for 12 hours then drained and refilled. After two months the solids in the tank were analysed (XRD and chemically) - and although there was plenty of loose powdered material in the base of the tank that had the magnets - it was largely aragonite , whereas the other was mainly calcite, a lot of which had deposited on the walls and the heating element. So yes it works - no it doesn't soften the water and yes - two fairly large NdFeB magnets either side of the inlet pipe (in attraction) is all you need.

Thanks so much for this review. I'm wondering how the less expensive units like this would do.

you did wind coils on copper water pipe, is this not bad for electromagnetic field. You need a plastic waterpipe and test again, then the electromagnetic field is stronger.

Good video, thanks! I have read that iron/rust over 0.3ppm actually deactivates water conditioners and makes them ineffective. Have you tried an iron removal system prior to the descaler?

Thanks for the video! I’m really interested in getting one of these electric descalers! 👍🏽👍🏽

You might not be using the right filtration system to treat your iron problems. You most likely have multiple forms of iron in your water (ferric iron and bacterial iron) and you would have to treat your well (shock the well) for the bacterial iron and use an oxidizer filtration system to remove the other forms of iron.

Would a pressure reducing valve in the middle of both wraps be ok, or do the two wraps HAVE to occur on the same flat pipe ?

Great review

My understanding is that this device should delay Calcium ions and Carbonate ions from combining to make solid Calcium Carbonate. If the delay is long enough, the solid isn't formed before in time to clog pipes and shower nozzles, etc. That seems to be why it's less effective at longer stretches of pipe (I think 50' was mentioned in the video). I think about seeding rain clouds: If silver nitrate is added to clouds, it creates places where rain drops can fall (precipitate). This seems to do the opposite: Expose ions to strong magnetic fields to make them LESS likely to combine (form solids that will stick to pipes and nozzles). Does it work? I don't know and the video seems a little inconclusive. Would I pay a few hundred dollars? I'd like to have greater evidence that it works.

Not sure where you got 50ft effectiveness from. That’s the general effective loop for magnetic ones. This capacitive one is said to be effective for over a mile. Also from what I understand is that it’s not effective on iron. It only reacts with calcium and magnesium. I have one myself that I just installed. My expectations is just less deposits on surfaces and maybe less buildup in the bottom of the hot water tank.

can this only be used on copper pipes?

Why did you start so far away from unit instead of straight down ,because your loosing turns on the pipe leaving themstraight over and turning in.i don't know if it works it works if not try the way straight down then turn in over the pipe

You should test it with water softener turn off

I would love for you to do another check since it has been a year. Great video, thanks!

No stereo?

Thanks.

Great video, well done ..

"RUST" => easy to fix ! Water flowing through a gravel tank (coarse sand/ 150 kg) and flushing with compressed air for 1/2h every week.

Buen video Gracias por tu recomendación Creo que sí lo voy a comprar

I wonder is you have a salt softener in place would the results been better

Do you still use a water softener? You mentioned you had one. I am trying to replace a salt based (bags of heavy salt) water softener/conditioner. I have a whole house filter and a then a Water Boss softener - but tired of the bags of salt. I have well water.

Can I use this in conjunction with a water softener or is it only 1 or the other? Would this make my water heater last longer

Thanks 💕dear

It's a water conditioner, not a water softener. Should try a whole house water filtration system that functions almost like the reverse osmosis filter, it will remove probably over 90% of your minerals including calcium and iron rust.

I have done a lot of digging since I really need something. I have to replace my water heater element every 10 month without adding salt to my softener. How long can this product extend my element usage? Half a month? Two month? Based on my weeks of reading, the main conclusion statistically is: "May or may not work", "a little improvement", "seems working". I am not sure if this type of product is really useful since my salt softener has extended my heater element usage 10+ years. I wish I am wrong, need somebody help me to see it.

Someone knows if this can be harmful regarding electricity and magnetism if installed in a bathroom (where the main pipe is), meaning being near your head? I don't know if the magnetism only "runs inside the pipe" or also to the other way around. Also if it's completely healthy, Do it means having the bigger one on an inch pipe will make its job better? Thanks!

3 years later... are you still using this system. I am having a problem with my water flow and looking at options I can use in conjunction with my salt softener to improve the flow. Any insight?

Did you turn of your water softener when you performed each test? Your results might not be accurate if the second reading was done right after the water softener was washed while the results from the first reading was done much longer after the water softener was washed.

I want to manufacture this product where can I find literature about this product,can you help.

Did you stop using the filters and softener during the experiment?

No, Yarna is effective for 1.2miles. The electronic ones are only good for 50ft

did the water feel better when you took a shower or no?

Thank you very much for this review. At least there is a choice before buying the $ 5000 soft water at my house. Any recommendations for soft water system less expenses please?

I've read a bunch of "theories" on how these are supposed to work, and none of them are plausible. They all seem to generate small voltage pulses that are supposed to chemically change the scale so it doesn't precipitate. It takes a lot of energy to do that. The Yarna probably generates similar pulses and uses the two copper wraps to couple them into the water. However, with a copper pipe it makes a capacitor and so those tiny pulses are going to turn into a current through that short length of pipe. Nobody can show evidence that such a tiny AC magnetic field will have any effect on hard water ions. Data over 3 months will be highly variable due to changes in the incoming water over the seasons, which is why people who have spent big bucks on similar systems sometimes report "I think it's working". Of course you don't hear from the from the others who realize they've been scammed. .A real test would show improvement instantaneously and could be tested chemically. Also, parallel water streams should be compared.

Are u suppose to put it before the water softener in the entrance of house before it hits the Presure tank or after ? The softener and all filters ???

How did this hold up over time? I've seen some pictures of pipes oxidizing. Thanks for the tips

rust + YOU NEED REINZAND / GRID IN A Tanks ( ~INOX) of +/- 500L with 1/3 GRID and rinsing every hour /5 minutes and meanwhile blowing in compressed air above, you can collect the water for .... . Replace GRID every 2 to 3 years ! "Will be perfect "

Do you think it will prevent scale build up on water heater elements?

Does it work on plastic pipes the same way as copper ones?

Did you stop using softener salt during trial?

After six months the improvement at our home is very low

Microphone is unbearable but otherwise nice review

NO WAY BUY FILTER+

Something major is wrong with your microphone, mumbling throughout the video.

:D This guy has well water with pump and tank. Dou you know that your tank has different pressures every time you open faucet? YOUR PUMP OPERATES IN RANGE OF PSI !!! There is a pressure switch and usually about 10 PSI difference in your tank you GENIUS :D More PSI = more water in your bucket! Also you have to install this shit on main line and after WH, if you installing only one I would go after WH.

Sorry but this is completely misleading. The conclusion is like "it is making an improvement", while all data is saying "this is not making anything at all". This is a goddam $300 device, that it has "no maintenance" is part of the scam, you already spent the money man, come on! And you keep comparing this to what you spent on filters, while it will never ever replace them, so what's the point of the comparison? Again this is misleading since people could interpret this like they can avoid the filters and place this instead, which is an heresy of course.
