This product review features the Calmat electronic water descaler.

If you are tired of spending hundreds of dollars due to hard water and scale build-up, the Calmat Electronic Anti-Scale Water Treatment System might just save your day (and pocket).

The unit uses high-frequency electronic impulses to change the physical composition of scale-causing minerals. To put it simply, the revolutionary technology prevents hard scale buildup from choking your pipelines.

Indeed, the best things come in small packages – the compact system measuring 7 x 2 x 6 inches saves your entire house’s plumbing and water-based appliances. As long as the iron and manganese content in your water is less than 1 ppm and 0.1 ppm simultaneously, you should check the bad boy out.

Sounds too good to be true? Let’s find out how far the claims are valid!

Highlights

At the beginning of our Calmat review, a few highlights:

Reduced Maintenance & Repairs

The Calmat removes scale deposits and rust that have accumulated in your plumbing system over the years. This most likely results in fewer maintenance and repair needs saving you time and money.

Higher Water Pressure

Cleaner pipes also means higher water pressure.

Universally Compatible Water Treatment System

The system is universally compatible, regardless of pipe material.

Easy to Install

The water descaler isn’t installation-free, but the process doesn’t take more than 30 minutes.

Service-Free

Once installed, there’s literally nothing you need to do afterwards.

Pros

  • Most importantly, the unit removes scale as well as rust deposited in your plumbing. The two of them are the most significant culprits responsible for damaging pipelines. This is possible due to a gradual release of carbonic acid[1], a natural scale solvent, during the water treatment process.
  • Not to forget, you may see a significant difference in water pressure around the house as existing clogging is flushed out over time.
  • Thankfully, the Calmat anti-scale unit isn’t dependent on water velocity, unlike the ones using magnets. Also, it works regardless of the pipeline material around your house. As long as the maximum pipe diameter is 1½ inches, this descaler is a viable option.
  • The system pretty much pays for itself over time. Don’t believe me? First, you save tons of money that would otherwise be spent on costly repairs to plumbing and water-based appliances, courtesy of hard water. Second, you save cash on cleaning supplies for your kitchen and bathrooms since it’s a breeze to clean with the conditioned water.
  • At the same time, no essential minerals are removed from your water.
  • Unlike traditional water softeners, the system uses neither salt nor chemicals. Thus, it is entirely eco-friendly and maintenance-free.
  • Not only that, the unit consumes only a minute amount of energy. Wave goodbye to massive electricity bills at the end of the month. With the Calmat, the increase in power charges is negligible (less than $10 a year)!
  • The unit is completely portable and needs no permanent installation – it works great for rentals and frequent movers.
  • The entire unit is designed, assembled and manufactured in Germany, famous for its premium production standards. Furthermore, Calmat is an over 70-year-old brand, which’s enough to testify to its credibility.
  • Finally, the Calmat has an international 5-year warranty so that you can purchase it with complete peace of mind.

Cons

  • Apart from a few dissatisfied customers who claimed the unit didn’t work, we have not seen any solid issues. As long as we understand that the system is not a water softener but a water descaler, most problems will be resolved.
  • Keep in mind that the unit is not water-proof and cannot work efficiently in temperatures over 55 degrees Celsius.
  • Of course, it does take time to show full effect since hard water can create hard-to-remove tough walls inside the plumbing.

Installation

Installation is tool-free and requires no changes in plumbing. However, if you attempt to fix the unit yourself, you need to be handy with a few wires. It won’t take you longer than half an hour if you have an electric socket near your main water line.

Select a point before the water heater, and you can begin the installation.

  1. Place the unit over the pipe you wish to install. Using the ties provided in the box, secure it to the pipe or mount it on the wall.
  2. Remove any obstruction on the pipe such as insulation etc. It does, however, work fine if installed on thick connection pieces.
  3. Now all you need to do is insert the red impulse cable in the left socket and wrap it tightly around the pipe. Secure the edges with a cable tie. You have two impulse cables in the package that need to be attached. Therefore, repeat the process with the black impulse cable. The tighter and neater you wrap, the better the performance. Also, the winding can be clockwise or anti-clockwise.
  4. Time to connect the adapter to the wall socket.
  5. Turn the system on.
  6. Now it’s time to program the unit. Input the diameter of your pipe and your pipeline material to select the program.
  7. Once the green control light blinks, it signifies you are good to go!

(All installation instructions are explained in more detail in the instruction manual.)

Maintenance

Like we mentioned earlier, the unit is maintenance-free. After the initial programming, it runs on its own. In case of power failure, the unit goes back to its original programming at the restart.

Just make sure the system isn’t subject to extreme temperatures nor prone to get wet. It’s worth mentioning that you might need to remove and clean a few valves around the house. Why so?

As the system works, it dissolves scale buildup in the pipes, which at times comes off as chunks. These lumps can choke the valves of your taps. The solution is to take it apart, clean it, and fix it back.

Nevertheless, the hassle is worth it since it means the system is clearly doing its job.

What’s Included

Here are the contents of the package.

  • Calmat anti-scale water treatment system
  • Red impulse cable
  • Black impulse cable
  • Power adapter
  • Cable ties
  • Manual
  • Warranty card

Calmat Review – Conclusion & Best For

Unlike many other water descalers that work (rather don’t!) using traditional electromagnetic waves, Calmat actually does the job. Thanks to its top-of-the-line technology, it’s best for removing severe calcification from pipelines all over the house for most of its users.

Many satisfied consumers vouch that their shampoo and cleaning products expenditure was cut to one third, and few mentioned how much easier it was to clean around the house. Safe to say, the unit is rather satisfactory since it’s eco-friendly, economical and needs no maintenance. Go ahead; you probably won’t regret it.
