Excellent

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

Main highlights

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.

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.
