YARNA

Capacitive Electronic Water Descaler System - Alternative Water Softener Salt Free for Whole House, Reduces The Effects of Limescale [CWD24, Max 1" Pipe]

YARNA

CA$169.99

More Details
Main highlights
- WHY DESCALING IS BETTER THAN SOFTENING: The Yarna CWD24 Water Descaler System will not eliminate wanted minerals from the water that are good for our bodies. The patented system allows the hardness level of water to remain unchanged before and after treatment, which mitigates the negative effects such as preventing minerals from forming scale deposits, which is the main disadvantage of hard water. Unlike traditional water softeners, Yarna does not require the use of salt or any water to be wasted.
- WHO BENEFITS FROM YARNA: We serve homeowners and small businesses by reducing the negative effects of hard water and protecting appliances. Our customers report cleaner pipes and faucets, lower costs for descaling and heating, and better overall water quality. Depending on the current condition of your plumbing and how large existing limescale deposits are, it may take up to three months to observe a significant improvement.
- RISK-FREE 365 DAYS, 100% MONEY BACK Service: You will enjoy a limescale-free environment as long as our Yarna house water softener descaling system is installed. To that end, should you not be satisfied with the products performance, you have a whole year to return it for a full refund!
- HOW IT WORKS BETTER: Yarna CWD24 is a Patented Water Descaler System designed to treat water for the whole house! Our descaling system treats water with electric pulses generated within the electronic unit and controlled by a micro-chip. These pulses are transmitted via our Ultra Flat Impulse Bands that are wrapped around the pipe and change the crystals in the water as it flows by, allowing for the breakdown of crystals that would otherwise buildup into limescale, which can break appliances.
- EASY, CLEAN INSTALLATION: All you need is access to a minimum of 10 inch of free pipe space with a maximum pipe diameter of 1 inch . Yarna water descaling system is completely DIY with no need for any tools or specialized help. Installation is simple, takes only 15 minutes and is 100% maintenance free. Our whole house water descaler works with any type of piping up to 1 inch thick including iron, copper, stainless steel, plastic, PVC, PE-x, and compound pipes.
