Capacitive Electronic Water Descaler Whole House Solution - No-Salt Softener System, Reduces Limescale Effects and Mineral Buildup - Model CWD230, Compatible with Pipes Up of to 2 Inches

I've had a traditional water softener almost my entire life, so when we moved from our home to a small, rented apartment and found out we couldn't have a water softener, I was super upset. But then we discovered the Yarna, and have been pleasantly surprised. It's been just over a year. No hard water deposits in bathrooms and dishwasher, although I do periodically clean the sink drains with Bon Ami. We use less detergent, soap, and shampoo than we did while the water was hard. The ony difference I notice between the Yarna and a traditional water softener is that I don't feel "slippery" after a shower.

FYI, I have my water pumped up in the outskirts of mountains and it is very chalky which my 50 liter water-softener tank cannot even take out completely. And I don't like the extra work it brings with it. So I went for the Yarna CWD48.For protection of the device outside against the rain, hot sun and small insects I mounted everything as much as possible in the shadow inside a IP67 P.P. box and shielded the box with Al. covered foam of 5 mm. thickness. The display can be monitored through a square opening in the front. Over the opening a uv-filtering see-through perspex piece is glued with P.P. glue and taped with black duct-tape. Given the low power consumption and the cool water flowing through the pipes I assume that the device will stay below its temperature rating. Because of the frequent net-power variations and interuptions, as a precaution I added a EMI-filter before the device's power-cord.On the short term, it may be my imagination and also considering that I no longer use the water-softener, it seems that when taking a shower the water feels a little different. On the longer term I hope and expect it will do the job!Update May 5 2023:I did not do any actual water-quality test-measurements but the CWD48 seems to be working better than the resin-based water-softener I used before.1) There is no calcium-blocking of taps, at least not when used on a regular basis! I cannot say if less used taps would still be clogged up over time.2) Static calcium build-up on the taps' environment does still happens, but a little less and (just) a little easier to remove.3) Previous calcium build-up in water-closet flushing systems may have caused AND prevented some leakage issues before. The calcium is now probably breaking down gradually and also causing small leakages with 2 of my 3 w.c.'s. I expect to fix this as soon as most of the calcium build-up in the reservoirs has disappeared. After having fixed it I expect/hope that leakages caused by calcium will be a thing of the past.P.s. coincidence or not, a (cheap) tap outside the house also started leaking a bit.Conclusions:--------------(Positive)All in all I am happy to have installed this device from Yarna, even if it were only for its maintenance time- and cost-reduction compared with my previous resin-based water-softener. And actually also a little for environmental- and health reasons.I like the space-saving and low electric power consumption too. Basic mounting of the unit as advertized is quite easy indeed.(Negative)Sometimes the environmental conditions are more harsh, like in my area. So one needs to make electric and/or mechanical provisions for that.The specific round shape of the CWD48 with its particular assembly holes positions, backside groove, as well as the asymmetric front screen relief makes it quite a challenge for non technically educated buyers with a limited toolbox. Imho, although maybe visually less attractive, a simple symmetric square shaped box design with a flat screen would make everything easier for DIY installation.Small point, the LED screen light intensity is a bit low. I realize though that an increase would rise the power consumption of the unit substantially (percent-wise) . Mind you, the trade-off works for me 😉 . Sorry for the long read 📚

Company and product both GRAVE DISAPPOINTMENTDon't waste your money! Both device and the company backing are a GRAVE DISAPPOINTMENT. We purchased a Yarna CWD48 a year ago - 1-10-24. We paid a lot for this - $329.07. We had a different device before that lasted many years, but this one looked better built. Looks can be deceiving! The cost was 3-4 times the other!We started to notice lime scale build up at just about a year - heavy. The device was still running, but clearly was not working. We contacted Yarna. We were put through the busy-work of taking photos of the installation, the graph on the device to show it was working, and answering a bunch of questions - about whether we also had a water softener, if the pipe had an electrical ground, etc. After back & forth emails we were told "Based on your photos, the waveform appears to be working, but the unit may be defective." Then the last email, which should have been sent first! Asking if we had an extended warranty. We did not. So after one year, the product is JUNK, and the company refuses to stand by it. We should have bought another of the old, cheap one!

So at our apartment where we used to live we had a fleck digital head water softener, extremely hard water with extreme iron. At our new house we just moved into, there is much lower iron content on this well water and just hard to very hard water. So I decided “screw the salt if I can get away without a softener” and went for this. I had a friend at work that recommended a descaler as he had one for his house.Install, if your handy it’s really not hard or complicated at all.What my water system here used to have before the descaler: an unknown micron filter from well, I’m guessing 30-50 micron, into a uv light (uvmax) out to the rest of the house. Was not having it.Now what my system consists of: 50 micron filter from well to a 30 micron filter, to two 10 micron filters in parallel, to the uv light, then the yarns is wrapped around blue pex, and then out to the rest of the house.The results 4 months later: immediately noticed ice cubes were clear on outside and had a white core (this is probably from the upgraded filtering). Shower head still shows little to no signs of buildup which I must say I am impressed but I’m not totally convinced that it’s the yarna that’s responsible for that.Our ninja coffee maker at our old place almost got thrown out because it was faulting out for “scale” and wouldn’t make coffee even after like 4 cleaning cycles. I tore it apart cleaned it with wire brush and it worked. So after moving I expected that maybe the hard water here would kill it again. Nope. It acted up like a week after moving in and I said out loud “ohhh H*ll nah!” Literally gave the side of it a smack and it started working. That was nearly four months ago. It has not faulted from scale issues since.Toilet tanks. Put a brand new toilet in a few weeks after moving in. Toilet tank still looks nice, although I can still see some black deposits but hey it’s a descaler right? Not a filter.Anyway faucets are looking good also.Long story short I’m not really seeing any significant effects from hard water anywhere after four months of use with the yarna unit. Does it work? I think it might actually help. Although I don’t think it is 100% effective, I am estimating that it does indeed help mitigate scale.Another note I have measured the water hardness with test strips, this device will not get rid of your hard water so keep that in mind, but this device is supposed to mitigate the effects of hard water. So is it worth the money? I would say so. I haven’t felt a need to get a water softener yet and spent money on bag after bag of iron fighter salt so gotta say I’m happy with it.Would this work at my old place? I’d be inclined to say not a chance. My guess is if you have extreme hard water and a lot of iron, this would be a waste of your time. That would require a softener or something similar. Maybe I’m wrong but that’s my estimation from my water system experienceUpdate: it’s been a few months. All of a sudden our coffee maker needed cleaning. I’m seeing hard water deposit on all of the faucet hardware in sink and shower. Coffee maker reservoir has a rim of deposits around the top hatch. Maybe this thing really was working and just stopped working all of a sudden? Going to reach out to see if yarna will replace it given they have 365 day money back 1 year return policy.
