Calmat works totally maintenance-free and is very simple to install, no tools or plumbing are needed. Calmat is an solution that protects the piping system and appliances against scale deposits and rust removing existing deposits. Calmat prolongs the lifespan of household appliances; less time and money spent on repairs and maintenance in your home. Calmat offers considerable savings in washing and cleaning agents and protects against lime-scale deposits on shower heads, sinks and faucets. The Calmat exclusive Electric-Impulse-Technology is based on the principle of physical water treatment; changing the crystallization process of the liquid calcium and this way the hard scale loses its adhesive power. Calmat works independently from the water velocity like other systems that use magnetic fields do. Calmat is suitable for all pipe materials. Review: Unbelievable improvement - This was one of those articles that I was skeptical if really work, but I give it a try. Our water is not the hardest, let me start with that. In about two months we are cleaning the toilet bowls with no chemicals at all, just a brush an very little effort. Previously we used chemicals and had to wait for about 15 mins. Just in money savings of the chemicals, time saved, and no chemicals smell it is definitely a win. Shower heads are not clogging and cleaning the shower is just a matter of a damp cloth. Easy and quick to install, one of the best investments I had made. Review: Set it up and forget it! - Works well and very inexpensive compared to buying tanks and paying for filters that need replacing. Just set and forget it. We've used it for over 2 years and have had excellent results. ## Features - Successfully treats water with hardness levels over 59 GPG / 1000 ppm.

Is it closer to the v3000 or v5000?** A: Yes, Calmat and Vulcan are made in Germany by the same factory. **Q: What is the maximum allowable distance between the two coils? As shown in the picture the distance between the two coils in my set up is 33 inches. B** A: As long as the majority of the cable is wrapped around the pipe, it should be effective. The minimum distance is 1-inch space between the two impulse cables. There is no maximum, technically the more the impulse cable is wrapped around the pipe, the better and more effective the treatment will be. the further the impulse cables are from each other the less surface area the cables are capable of covering the pipe. **Q: Will the 1 1/2" setting work on pipes that are 1" or should you just use the 1" setting? Silly question, I know, but it says "up to 1 1/2" - Thanks!** A: It wraps more than enough in either setting. **Q: Grounded plug? The only outlet near my water inlet is for 2-prong.** A: The Calmat device works with a 2-prong power adapter. The outlet near your water inlet will work well. You can also attach a standard 2-prong extension cord to the power adapter if it is not long enough to reach. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Unbelievable improvement *by D***O on January 2, 2020* This was one of those articles that I was skeptical if really work, but I give it a try.

Shower heads are not clogging and cleaning the shower is just a matter of a damp cloth.

Just set and forget it. We've used it for over 2 years and have had excellent results. ### ⭐⭐⭐⭐ Working well *by C***. on June 27, 2022* I read quite a bit about electronic descalers, both the magnetic and capacitive types. Reviews and testing were mixed and I honestly didn't think it would work. My main reason for purchasing the unit was to reduce or eliminate the calcium deposit ring in our pool. It's hard to remove and expensive to have it done professionally. We also have calcium residue on shower heads and glassware from the dishwasher. I tested our water and it is not very hard. The only issue we have is with calcium. From what I have read, it won't help with any other minerals or metals. All of the units I looked at are designed to be installed on the inlet water pipe in a basement. We live in AZ, so no basement. This makes installation a bit harder. I bought this unit, because I liked that it was made in Germany and had lots of approvals, such as CE, UL, TUV, etc. At least I could be confident that it wouldn't burn down the house. Since it's not rated for outside mounting, I had to purchase a weather proof box to mount it. Not too bad mounting and we have a electrical outlet relatively close. What would be ideal would be the unit already mounted in a weather proof box with a small solar panel and batteries. We have had the unit installed for 2 months. Our shower head has zero calcium build up in this time. Also, glassware does not have the spotting and rings that they did before. So far, the pool is fine, but it will take several more months of testing before I know that it definitely works there. So, at least in our case, it does seem to work. I'll try to report back again in a few more months with additional observations. UPDATE: I've had the unit for a little over a year. Calcium build-up on the tile of our pool is definitely less. The big positive is a pumice block removes the build-up fairly easily. This is much different than before the installation, when the calcium was almost impossible to remove. Based on this, I would say the unit works as advertised. ## Frequently Bought Together - Calmat 1-6004-000USA Water Conditioner, Translucent and Black - Varify Water Hardness Test Kit - Water Testing Kit for Home, Drinking, Well, Spa, Swimming Pool, Softener, Dishwasher & More - Hard Water Test Strips for Calcium, Magnesium etc (0-425 pmm, 150 Strips) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/58211472-0-59-gpg-electronic-anti-scale-and-rust-water-conditioner](https://www.desertcart.de/products/58211472-0-59-gpg-electronic-anti-scale-and-rust-water-conditioner) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-14*
