Residential (Domestic) Scalewatcher® Descaler Solutions

You may know that the washing machine can fail prematurely due to hard scale buildup. Additionally, the problem also affects boilers, coffee makers, kettles and water faucets and aerators in the kitchen and bathroom. Scalewatcher® is an excellent and environmentally conscious way to stop these problems. Scalewatcher®, attached on the incoming main will protect all water using applicances in your home.

When considering a model for residential use, we recommend the Scalewatcher® 3 Star, the most powerful residential unit for indoor use, effective when treating the hardest of waters. For outdoor installation and for swimming pools, you should purchase the Scalewatcher® 5 Star Weather Proof Heavy Duty model. The Scalewatcher® Small Wonder should only be considered when financially constrained, albeit it is not made for longevity.
WARNING: Avoid unpatented versions of Jan de Baat Doelman's Scalewatcher®. There are "copycat" units which do not perform the same, whereas they cannot use Scalewatcher® technology. In addition, new companies are relabeling the Small Wonder and 3 Star, to take advantage of our global marketing. They close up or change names and your warranty is instantly worthless. Scalewatcher® cannot honor the warranty of unethically relabeled units.
