There are a number of phrases that have to do with water: “If you are underwater, it means your home is worth less than you owe”; “If you are in water over your head, it means you spent more than you have”; and, “water, water everywhere nor a drop to drink,” a line from Samuel Taylor Coleridge’s late 18th century poem titled Rime of the Ancient Mariner. The last phrase has a number of meanings, one of which we can all relate to, which is: We live on an island surrounded by salt water that we can’t drink. The same salt is in the air, and it’s corrosive.

If you’ve lived in Hawaii for even a short length of time, you have seen the outside of your refrigerator, washer or dryer deteriorate — in many cases before its warranty runs out. What you can’t see, though, is what you should be aware of before you get into hot water.

We’re talking about your water heater. Our water is “hard water,” and it causes corrosion inside the water heater. For some reason, we never think of water heaters as appliances, but they are. Your good old water heater is hidden in a corner, behind closed doors or somewhere else where you can’t see it on an everyday basis. After all, water heaters aren’t very glamorous, and they rarely come in attractive colors with high-tech buttons and bells. It is a workhorse appliance, though. It dependably heats your water day in and day out, until the buildup and corrosion inside the water heater takes its toll. Then one day, without warning, there’s no more hot water.


The anode rod inside the water heater is meant to attract the corrosive minerals in the water to delay corrosion in the tank itself. But over time, the accumulation of limescale deteriorates the rod. To prevent that from happening, you need to heed the advice of Harald von Sydow, director of Nano Tek-On.

An expert in environmentally friendly nanotechnology, Harald von Sydow is particularly high on a little unit called HydroFlow these days. It stops limescale and calcium buildup from forming in plumbing and water-using appliances.

Remember, the water heater is an appliance. The HydroFlow unit, easily installed on your plumbing (installation is a plug-on with no pipe cutting), prevents buildup without changing the mineral composition of the water. This means that the water coming out of the water heater will flow more freely, and the water will be hotter, since your water-heater is working more efficiently. HydroFlow breaks up existing scale, maximizing the performance and energy-efficiency of your water heater — and all water-using appliances — at the same time. These include dishwashers, washers, refrigerators, freezers, spas and pools. And it is maintenance-free with no filters to buy.


HydroFlow is specifically designed to stop limescale buildup. When a HydroFlow unit is installed, randomly varying electric fields are introduced into the water throughout the entire plumbing system, breaking up corrosion and limescale precipitation. The suspended particles wash away in the flow. HydroFlow normally dissolves existing scale in just a few months. It also makes it possible to slow down corrosion by up to 65 percent, extending the lifespan of existing corroded parts.

HydroFlow’s technology also can reverse limescale buildup. For example, HydroFlow technology increases the efficiency of water heaters by removing the scale that builds up over the electric elements. By keeping all particles in suspension, HydroFlow also prevents corrosion-causing calcium deposits from forming on the bottom of the water-heater tank. This greatly lengthens the lifetime of the tank. There is also an added bonus, as this process keeps shower doors spot-free with minimal maintenance.

Nano Tek-On specializes in environmentally friendly surface treatments and water-conditioning including HydroFlow; sealants for glass and natural stone; antimicrobial coatings that kill bacteria, viruses, odors, mold, mildew and allergens; and self-cleaning surfaces.
