UK-based Eddy Water Descalers makes the Eddy Electronic Descaler, a system that uses electromagnetic treatment to effectively soften water (this treatment does not actually remove hard water minerals, but prevents them from forming scale). Like other electronic systems, the Eddy descaler is affordable and very easy for any homeowner to install. Wrap some wires around your water pipes, plug it in, and you’re done – that’s basically all there is to it.
One of the most attractive aspects of this system is the one-year money back guarantee. On top of that, it also features a lifetime repair or replace warranty.
You can order the Eddy Electronic Descaler though any number of online retailers, including Amazon.com.
