    • Great product; Great support; Highly cost-effective
BOTTOM LINE: After 3 years... still working strong! Tremendous time-saver and money saver on continually replacing salt weekly to monthly! Customer support is fine also! My first interest in this were the reduction of unnecessary chemicals (salt), the cost and time savings as well as the technology. We have very hard water. The TDS (total dissolved solids) is extremely high. Lots of calcium precipitation with this or the salt-water treatments. Installation location on incoming city water pipe: We installed our Yarna unit before the house water shutoff valve and connected the cord to a standard wall outlet in the basement. We did not use an extension cord. We have unplugged and reinstalled the wrapping coils at least once as we wanted a tighter fit than we initially had. Hot Water Heater to Navien A2: We had an old 60 gallon hot water heater that we replaced with a Navien A2 unit after about 1.5 years of using the Yarna unit. Both are were in our basement installed just below the kitchen. The Navien has a pre-filter so after a year we had it serviced. There were some slivers of calcium buildup in the pre-filter which we removed. There has been no negative impact on the Navien A2 unit so it's working fine. Dishwasher: We have a Bosch dishwasher (15 years old?) that exhibited serious internal calcium (white) buildup on the bottom and sides after we decided to not use the salt-treated softwater approach. Distance from the Yarna unit is about 20' (basement to kitchen). Then we installed the Yarna CWD24 as our city water lines are 1" (CWD30 works for 2" max). After about a year or so, I noticed that the dishwasher deposits were coming off. Additionally, our dishes were looking better with less calcium on them. I eventually purchase the Bosch Dishwasher Quick Descaler (#00312918 - 2 pack). The first time I used it it really (!) cleaned the insides of the dishwasher. About 6 months later, I used it again and the insides are sparkling. So we have a 'new' dishwasher! ;-) Faucets: With such success on the dishwasher, we then went to our faucets (9 in the house - some chrome, some brass). I didn't do the hose connections on the outside. We put CLR in 50% strength on almost all faucets, some with 100% strength and let it soak over night to nearly a week! In all cases we had success. The only issue we still have would be related to where CLR can't get to but these are being taken care of via the Yarna unit's ability to 'soften/eliminate' the calcium buildup in the pipes. Shower heads: Same results with CLR but we were able to remove the shower heads and soak them. Toilets: Inside the water tanks we noticed the buildup and crusting of the calcium which is being neutralized still to this day. We did replace some of the water-closets workings but not all since the calcium made some parts 'hard' (flapper etc.). Some flappers had crust on them that eventually came off - somewhat encouraged by manually wiping these areas and stirring up the calcium deposits from the bottom of the tank to be flushed out. The actual bowl is cleaner also. Shower doors: After years of taking a shower without a softener and then using the Yarna unit we noticed that parts of the shower doors (glass and brass) were losing the calcium deposits (being washed off without any effort on my part). We then started using CLR (1.5" paint brush in a cottage cheese container) and then Kaboom to clean these doors even on cultured marble. I personally like CLR a bit better (used at 50% and Kaboom at 100%) but both work! Both have some 'slickness' to them but it's very minor when you're working in the shower/bath stalls. The shower doors, floor, brass etc all look 90% better but I'm still working on them. Crevices and screw heads take a bit more time. Water taste: Removes salty taste and makes water taste more 'normal'. This may be a personal preference. Cooking: Nothing changed except there's no calcium deposits that occur nor is there any residual 'salt' added. Health: Hard to determine but, with the Yarna unit, we're drinking water without the additives. I would easily rebuy! Actually thought about a 2nd one but I’m told it’s not needed. I don't know how long it will take to fully do our pipes. I don't know of any downsides unless you desire the salt and 'slicker' water. ... show more

    • Does exactly what it's designed to do
This product is designed to help specific plumbing systems, and it does very well when used in the correct application. Hard water, but not too hard. Reasonable minerals, not excessive. This applies to most wells but not all, and where you have very high levels you probably need a full softener. Also note there are two descaling systems that I can see, one that works for 50 feet (which is nothing) and one that works for 1.2 miles (the good one). Get the good one. We are on a rural well with moderate hardness and minerals in the water. 3K square foot house with well over 50 feet of plumbing. This descaler has pretty much eliminated the orange iron stains on bathroom toilets and shower and when there are water spots in sinks or on counters they wipe off easily where they used to take serious scrubbing. We have one stainless sink that always had scale buildup because the drain was not designed quite right and a bit of water pooled and did not drain. No more, the scale is far less and comes off with a light scrub where it used to take soaking in vinegar or Barkeeper's Friend overnight. Super easy to install, you do have to get AC power to it. I put it on the 1" incoming line from our well before it hit the pressure tank. We noticed an immediate difference after installation. Several months in and we have no discernible orange iron staining and substantial improvement on water spotting on glasses in the dishwasher and on countertops. I did not have room in the well closet for a full softener so this was a good solution to keep minerals in suspension rather than removing them. ... show more

    • It works!... depending on your goals
There's lots of debate about the effectiveness of electronic descalers. So does this work? Yes, but it might not do what you're expecting. First some background: The water in my area is very hard (~25gpg). It also has a distinct odor and a metallic taste. My salt-based water softener failed so after reading reviews, I decided to try an electronic device. The nice thing about this system is how easy it is to install. I "might" have taken 10 minutes to wrap the pipes and secure them with the included zip ties. I was able to place this directly after the municipal water shutoff in my home. There is an obvious difference in the water after going from no conditioning solution to this descaler. After a month of use build-up in pipes has decreased. There are noticeably fewer limescale deposits on faucets, shower doors, etc. So it does work. Since this device doesn't change the chemical makeup of elements in the water shower water still feels hard, soap doesn't lather much better, and skin gets the feeling of a slight coating. Our skin isn't drying out like the normal hard water but it still feels strange. Also even with multiple filters our water still has a strange taste and odor. (Not the device's fault since it's not a filter) So with all that, in mind, I'm going back to a traditional softener to treat our water. However, because this device was so easy to install and I do see less build-up, I plan to keep it in addition to a salt solution. Water softeners are usually after some infrastructure like water spigots, pool systems, etc (you don't really want salt on your lawn) so this device will continue to maintain those plumbing systems in my house. ---------- Edit April 2021 --------------- After reading this honest review, the company reached out to me and offered me either a refund or a higher-powered unit. Every interaction with their support team has been fantastic. This is obviously a company that cares that their customers find a solution and I appreciate that perspective. ... show more
