What it does for your water
The YARNA CWD48 Electronic Water Descaler is an electronic descaler that works on the pipe from the outside.
Expect no change on a hardness test. Salt-free units are sold on reducing scale build-up; removing calcium and magnesium takes an ion-exchange softener.
Electronic units need a power outlet near the pipe and work only on the pipe they are wrapped around; the maker lists which pipe materials and diameters suit them.
Other listed details: mounting DIY; power Corded Electric; capacity stated as 1 tons; model CWD48; material Copper.
The listing gives dimensions of 1 in (L) x 1 in (W) x 1 in (H) and installation kit in the box.
