What type of pipe material does Calmat treat? calmat is suitable for all pipe materials: iron, galvanized iron, copper, steel, stainless steel, plastic, PVC, PE-X, compound pipes (any material mixture) etc.
Do plastic pipes and copper pipes need scale protection as well? Yes. Plastic and copper pipes are prone to calcification, too. The smoother a surface is the longer it can resist the process of calcification. It may take longer until plastic or copper get a first layer of scale. However, once that first layer has built up, the scaling process proceeds just as fast as on any other surface or material.
Can Calmat be used with a Water Softener? 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.
Does the winding direction matter? The winding direction (either clockwise or counter clockwise) doesn’t matter, each impulse cable can be wrapped either way.
Does the number of winding matter? The number of winding around the pipe does not have to be necessarily equal to each other and the unit will perform well regardless. Winding the cables a few inches away from the Calmat device is ok as it wont affect the transmission of the electrical impulses. Ideally we recommend winding the impulse cables as tight and neat together as possible for maximum performance. How long does it take Calmat to sanitize the pipes? 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.
Will the scale that is cleaned out block the pipes? 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.
How long does the effect last? 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 days).
Does calmat help with green colored water problem? Green colored copper pipes are an indication to 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.
Does the placement of the unit matter? No, the placement doesn’t matter. Calmat can be installed even upside down and is going to work well. It will treat the water from the point you install the unit on wards and will protect the rest of the piping system.
What kind of warranty do I get on Calmat? calmat has a full 5-year warranty. It is German TÜV-certified and is CE, CUL and UL listed. Your calmat unit is 100% covered under most circumstances. By purchasing from the manufacturer and listed distributors, your warranty is well-assured. German quality standards and excellent customer service have been our priority for over 60 years.
I heard of similar products and that they don't work. Can you explain? There are similar looking products to calmat on 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.
