## Features

- HOW IT WORKS BETTER: Yarna CWD30 water descaler whole house that treats water with electric impulses which are generated in the electronic unit & are controlled by a computerized micro-chip. The signal-frequencies are transmitted via the ULTRA FLAT IMPULSE BANDS that are wrapped around the pipe. The bands form a frequency-field that changes the crystals in the water as it flows by. By that, the crystals won't stick one to another forming the limescale that breaks your appliances.
- WHO BENEFITS FROM YARNA: Our customers report cleaner pipes and faucets, lower costs for descaling and heating, and better overall water quality using our whole house water softener system alternative. Depending on the current condition of your plumbing, it may take up to three months to observe a significant improvement
- EASY INSTALLATION: All you need is access to a minimum of 10" of free pipe space with a maximum pipe diameter of 2". Yarna whole house water descaler is completely DIY with no need for any tools or specialized help. Our whole house water descaler works with any type of piping up to 2" thick
- WHY DESCALING IS BETTER THAN SOFTENING: The Yarna CWD30 water softener descaling system won't eliminate beneficial minerals from water. Additionally, unlike traditional whole house water softeners, Yarna does not require the use of salt and does not allow water to be wasted
- 365-DAY RETURN POLICY: If the product does not meet your expectations, it can be returned within one year. Our support team is available to assist with any inquiries or concerns after your purchase.

## Questions & Answers

**Q: Can I put one of the coils in the cold water pipe going into the water heater, and the other coil on the hot water pipe coming out of the heater?**
A: You will only be the descaling the hot water, not the cold. Since the cold line tease off before it hits the water heater and comes out hot. Get it

**Q: Can i wrap the cwd30 and/or cwd48 with thermal foam tape (for the winter) when installed outside?**
A: Thank you for your question. Yes, you can use thermal foam tape or other insulation devices to protect the YARNA CWD30 or CWD48 Electronic Water Descaler.  Although both units are for indoor and outdoor use, it's still an electronic device and we still need to take safety precautions. Thus it's best to still be protected from too much heat and cold.

**Q: Is there a limit of time after water is treated that the water goes back into its original state when the waters not being used?**
A: Yes. The water will recombine. Just flow cold water for a few minutes. Hot water (with tank) is another story unless you put the device on the outlet of the hot water tank. The best place to put the device is close to the tap (outlet). Device not perfect but very good at cold water inlet into the house.

**Q: I'm planning to add this in my existing water softener that uses salt. Would you recommend it installed in the inlet or outlet of the resin tank?**
A: Thank you for your question.  If you have a salt-based water softener, our product is redundant. Salt-water softener normally removes minerals (including Calcium and Magnesium) in the water and replaces it with salt. While water descaler acts on the calcium and magnesium in the water by changing its structure so that they looses it's adherence effect and therefore won't stick anymore to any surfaces. So if you have the salt-water softener, it will defeat the purpose of having a descaler. So our recommendation is to only choose one of them and NOT have both working. Depending on what you want/need I strongly suggest installing only one of the two. If you want no minerals in the water then salt systems are the way to go. If you want to eliminate the nasty side-effects of calcium, Yarna will do that.
