Not sticky anymore, the limestone is now pretty easy to clean and doesn't clog our filters like before. Major improvement. I waited many months before writing this review.

Bei Amazon sind 4 W Leistung angegeben, am Gerät sind es 2 W, und der tatsächliche verbrauch liegt bei0,3 bis 0,7 W . Bei diesem verbrauch darf man keine wirkung erwarten.Nach 3 Monaten keine änderung immer noch wasserränder in Kaffeemaschine, Töpfe oder auf ArmaturenNicht empfelenswert !!!

funciona pese a mi escepticismo.

HQUA 5000E Electronic Water Descaler, Alternative Water Softener, Salt Free, Limescale and Rust Removal and PreventionShipped on October 27 arrived on Nov 3. Good time for delivery.The box had damage to one corner, but they packed it so well there was no damage to the unit. It took me a bit to figure out where on the line I wanted to place it as there are options. I Installed it close to the water purifying system and at the start of the water entry into the house. This way I could take advantage of descaling the water before hitting any faucets or fixtures. The installation didn't take long at all, finished in an hour. I also had to make my own bracket as it did not come with the two sided tape, but no biggy. I kept the box and all the stuff inside in case I had a problem and had to return the unit. The Pics Tell More. Enjoy**UPDATE **This has been installed for a couple of months now. I did my D&D and cleaned all the faucets and any water outlets with CLR to be sure it was clean. As of recent I noticed a build up on all my outlets. It looks like the unit is on but is not doing it's job. This upsetting as I have all new water piping installed and was hoping this would stop the build up of calcium AS IT SAYS IT DOES .... but I guess not. So it is one of those buyer beware things. At one time you could contact the seller but this new AI thing Amazon is using is less than useless to get answers. They should have left well enough alone. Since I cannot get to the seller direct I cannot get the answer to the question , "of why it's not doing it's job" ... so now I am left hanging??

Been a year now so time to review. I decided to try this out instead of a water softener. We bought a house on a well with hard water issues a year ago. The previous owner didn’t do much to combat the scale from the looks of things. So I spent quite a bit of time descaling everything in the house. It was bad! I mean 1/2 inch of scale in some places….. So I installed this. The hard water spots still happen. As this does not remove the deposits from what I understand. But it stops them from binding to surfaces as quickly. So the spots seam to wipe up easily. Also hair felt sticky after a shower when we first moved in and there was a ton of soap needed to get a lather. Not anymore. Was it this? Or the new UV system? Hard to say…..I also noticed a fine powder once on the bottom of a pot on the stove that had dried out. I think it was stuff released from the pipes. Also the dishwasher has way less spotting. So yes I think it helps. But seeing as I did such a good job of descaling to begin with it’s hard to say if it was my hard work or this unit. One spot I have noticed no change is my new shower wands. The metal hoses seem to scale up badly. It does not come off easily. For this reason I knocked off 2 stars. But that said the lather and hair feeling and lack of dishwasher issues make up for that. The dishwasher had the worst scaling issue when we took possession. It was unusable. So to see it working so well now is a welcome surprise. And the scale in the toilet tanks is no longer forming. So I would say it helps. But I would also say it’s not perfect. If it breaks I would wait to see if I notice a change before I replace it. But I also do not want to unplug it to see if it’s making a difference in fear of starting from scratch again. If that makes any sense lol.

****Update****I took two glasses of water, filled one before installation and one two days after. After two days of sitting, the 1st glass of water drawn before installation had noticeable precipitates of Calcium Carbonate (see picture). The 2nd glass of water drawn two days after installation and two days after sitting, had very little precipitate and no "clumps" of CaCO3 crystals (see other picture). The bottom line: THE PRODUCT SEEMS TO WORK on our 25 GPG well water. If the manufacturer would modify their installation method for wall attachment (see below), I would change the rating to five stars.***Original Post***The product arrived in less than 24 hours (congrats, Amazon) in an artful and well engineered box. It was so well packaged, with custom foam cushioning, that it was somewhat difficult to remove. Installation required about 30 minutes to wrap the copper bands around the pipe and use the supplied double-sided tape to stick the unit to the wall (Picture 1). As one might expect, double sided tape is inappropriate for concrete walls and yielded in about 8 minutes, allowing the unit to drop and dangle from the connecting wires. I am not sure what kind of walls the designers had in mind for likely installation, but in the U.S. it is highly likely to be poured concrete or concrete block. The double sided tape will not stick to these surfaces. It might possibly work with clean drywall, but the likely point of installation would be a basement in many/most parts of the U.S. (anywhere the ground freezes in the winter).Instead of the recommended wall mount, I screwed the supplied cable tie brackets (that were intended for the pipe mount option) to the wall with masonry screws and clamped the unit between them with cable ties (Picture 3). I believe this approach to be stable and durable.The system appears to be well constructed and I prefer the flat band pipe conductors to the more common cables, as it supplies a greater surface area per length of pipe compared to the insulated wire design of other systems. This approach should improve the electric field strength within the pipe. I am conducting a test of rate of precipitation of CaCO3 before and after installation. I will update this review, when I am able to evaluate efficacy.

Update 2/8/21: The SS tub in our dishwasher is sparkling once again after the first use (was clouded with white layer of lime or soap residue). My wife notices improved lathering and skin feel after her shower. Laundry air dries to a softer feel. I am very happy so far- will update from time to time.Local water is relatively 'hard' and we didn't want to commit to a traditional water softener for the obvious reasons being cost, hogging up space (we have no basement), maintenance, drinking water taste + removing healthy minerals, and the nuisance of salt. After doing some research, I decided to give the HQUA a try for its decent reviews and the copper tape seems to be an improvement over the simple bell wire used on some other competing descalers. It arrived well-packaged and with a nice booklet. To be honest, $150 is a small gamble vs. thousand$ on a salt water softener. What's to lose?Planning the installation was the hardest job due to water inlet and figuring out the plumbing; the place I chose was not optimum but the only option in a loop inside the water meter. Actual installation took about an hour because I wanted to be meticulous. The hardest part was running power to the unit since no power was available in the closet where street water enters the house. I was careful to do the wraps in opposing fields (instructions say this wouldn't be an issue but I wanted to give best practice if it would make a difference). Also our inlet pipe is copper (instructions suggest plastic is best).From the first time I washed my hands, I could see and feel improvement in the lather and rinse. Later in the afternoon I took a shower and was pleasantly surprised at the improvement- both in suds, skin feel after rinsing, and my hair after it dried (more fluffy). Note: The instructions suggest it takes time to feel the benefits, however the fact that we have a TANKLESS hot water heater and no summer/winter boiler system for heat may have made the effect more immediate. Due to this, the 'descaled' water turns over faster in my theory without 'sitting' in pipes or the tank since it seems the effect diminishes over time as the molecules 'decouple'. We wouldn't have this issue in our home.So far I am totally pleased: Wife is showering today (I am waiting for her objective comments) + we haven't done any laundry or run the dishwasher yet. I will report back periodically. But I can tell you for our home, this thing is a home run so far.Objectively every situation is unique: The hardness of our local water may be within a range that is more easy to descale (I tried to find a hardness spec from the local Water Authority to no avail . Tankless hot water means less comingling. When I carefully digested the negative reviews, it occurs to me (since I had a hard time figuring out the plumbing) user error could be one of the reasons for less-than-optimal results, i.e. not locating the inlet for all the water; not wrapping coils to allow space between them or tight enough; comingled fresh/descaled water; or the local water itself. CONCLUSION: Seems to work great for us!
