Question 1

How long does it take Calmat to sanitize the pipes?

Accepted Answer

After the installation you typically see some or all of the effects in the first few days. Depending on the water compositions one effect may be stronger than the other. Typically you notice that soap and shampoo lather much better, then you may expect the water boiler, kitchen and bathroom to begin to lose limescale accumulation. We have users that have seen some effects right away, others after a week and some after a month. The whole lime scale disintegration process from your piping system usually can take from few weeks up to six months; This will vary on the amount of build up through out the past years.

Question 2

Can Calmat be used with a Water Softener?

Accepted Answer

Yes! Calmat can be used by itself or in combination the water softener, you can use it either way; if you want your water to be softer, you can keep using both the water softener and Calmat, or if your goal is to simply remove the lime scale from the pipes and appliances, you can use just Calmat. Also We recommend to place Calmat before the water softener so the softener is treated as well.

Question 3

How long does the effect last?

Accepted Answer

Calmat is continuously removing new and existing limescale. When mono-crystals are created by the impulse variation, it is important that they grow as long as possible before they start their way through the piping system. The larger the crystals, the longer it takes until the crystals fall apart again and eventually "die". In warm water, these crystals grow faster and therefore are stronger and live longer. This explains why the calmat-effect lasts the longest in warm water (up to seven days) and shorter in cold water (approx. two to three days).

Question 4

Does Calmat help with green-colored water from copper pipes?

Accepted Answer

Green-colored copper pipes are an indication of oxidized copper or copper rust - similar to rust in iron pipes. The Calmat treatment produces hydrogen dioxide (H2O2) which protects blank copper surfaces against oxidation. This way, Calmat reduces the green colorization of the water.

Question 5

Will the scale that is cleaned out block the pipe?

Accepted Answer

No, the scale is slowly dissolved back into a solution and the calcium and magnesium is washed away in the water as a fine powder.

Question 6

I heard similar products do not work. Why does Calmat work?

Accepted Answer

There are similar-looking products to Calmat in the market that claim to do the job but don't. Almost all other products on the market are working with inductive (electromagnetic) technologies. You can easily recognize them by their cables. Those cables run in a loop from the electronic unit - to the pipe and back into the unit.

In comparison, Calmat works exclusively with capacitive impulses that guarantee a stable output. Its impulse cables end on the pipes, similar to antennas. Furthermore, regardless of inductive or capacitive impulses: Calmat utilizes far wider frequencies of 3,000 - 32,000 Hz (= 3-32 kHz) and operates with energy levels at 24V.
