The Scalewatcher Nano Water descaling Unit


Compact and portable, the Scalewatcher Nano is an eco-friendly electronic descaler for your small home or apartment. Designed for residential use only, the Scalewatcher Nano is an excellent way to address hard water problems in your home. While not harmful to you, hard water can wreck havoc in your home; creating scale build-up in your pipes, on heating elements in washing machines and leaving an unsightly mess on your faucets and sinks. Ideal for homes with municipal water, the Nano is the smart alternative for treating hard water.

The Scalewatcher Nano unit consists of an electronic unit and a coil, which is wrapped around the pipe of the incoming water supply. The electronic unit works by sending out magnetic and electric fields that have a continuously changing signal. This signal agitates scale-forming calcium and magnesium in the water causing them to change shape into smaller, rounder crystals that will not easily adhere to themselves or any other surface. Additionally, because no new scale layers are being formed, old scale deposits are slowly removed by the force of the flowing water. Note: this action will temporarily increase the hardness of the water until all the scale layers have been removed.

The Scalewatcher Nano is easy to install and maintenance free. It is compatible with all types of pipes, including copper, steel, PVC and lead; all you need is at least 4” of straight pipe in order to properly install the unit. Not only will one Scalewatcher descale and protect your whole home, but it will prevent new scale from forming on everything from sinks and bathtubs to hot water systems and appliances, extending their life and improving their efficiency. Unsightly existing scale found on faucets and showerheads is softened over time with the use of a Scalewatcher making it easier to remove. The Scalewatcher Nano unit uses very little energy and costs less than $14 per year! Unlike other water softening systems that use salt or other chemicals, the Scalewatcher is environmentally friendly as it does not use any of those things, making it gentler for your skin.


The Scalewatcher Nano is guaranteed to prevent or considerably reduce the accumulation of scale and to remove already existing scale during the first 30-90 days of installation.
