Is the 12 month money back guarantee really "no quibble"?
Our 12 month money back satisfaction guarantee is completely "no quibble". If you are unhappy with the performance of your Eddy unit for any reason whatsoever within 12 months of purchase, simply return the unit to us for a full refund of your purchase cost. As a matter of principle we will test any returned unit and inform you of any fault condition so that you can request a replacement unit. Eddy is sold for DIY installation so we do not undertake to reimburse any costs incurred from the use of professional tradesman for fitting Eddy. We receive a negligible number of returned units and the vast majority of our customers are highly satisfied with the performance of Eddy which either meets or far exceeds their expectations.

How does Eddy inhibit scale formation?
Eddy produces a complex electro-magnetic wave which is applied through two coils wound round your incoming water supply pipe. In this way your water is subjected to an ever changing magnetic field as it passes through the coils. This alters the electric charge distribution on the crystals of limescale in your water supply and changes the adhesion properties of the limescale so that it no longer deposits itself on your clean surfaces, within your pipes or inside your appliances, so that they are freed of its damaging and corrosive effects. Eddy does not add anything to the water and it does not remove any healthy minerals. Limescale stays in solution in the water and is simply washed away!

Is Eddy a water softener?
Eddy is not a water softener, but in the majority of cases it can remove or greatly reduce the nuisance of limescale without the initial cost of a water softener and without the ongoing costs of salt for a water softener. Due to our 12 month money-back warranty you can try Eddy without any risk and we are sure you will agree with many thousands of satisfied customers that Eddy will remove the need for an expensive water softener in the majority of cases. Please see our 100% genuine customer testimonials from just a few of our happy customers who agree that they do not need a water softener after fitting Eddy.

Where do I fit Eddy?
Eddy is usually fitted to your main cold water supply line at the point where it enters your home. In this way all of the water in your house will be treated, including water used in the hot water system. In cases where you cannot get to the main supply pipe, Eddy should be fitted at the earliest accessible point in the system.

Can I fit Eddy outside?
Eddy is designed to be installed indoors but some of our customers have used it outdoors by installing in a weatherproof enclosure. The plug-in power unit should also be protected from the weather. Another option (if practical) is to use longer coil cables so that the main unit and power supply are mounted indoors, but the cables pass through the wall to the pipe. Alternatively the main unit can be placed outside (in weatherproof enclosure), and the power supply can be used with one of our low voltage extension power cables to get from the power socket indoors to the main unit outdoors. We sell a set of cables with longer coil wires for larger pipes, but if these are used on a standard one inch pipe, then the distance from the coils on the pipe to the main unit can be up to 8 ft. The standard power cable supplied is about 6ft long. We sell extension low voltage power cables in lengths of 9.5ft and 16ft.

Can I fit Eddy myself?
We believe that anyone can fit Eddy safely and simply. All that is required is the ability to identify the mains water inlet to your home (instructions given) and find a mains electricity socket within a short distance of the Eddy installation position (or use a mains extension lead if necessary). No special tools are required. If, however, after reading the comprehensive instructions supplied you feel unable to tackle the job, any electrician or plumber should be able to fit Eddy for you in about half an hour.

I have a large house. Is Eddy powerful enough?
When we designed Eddy we decided to produce one device capable of treating any sized property up to and including small industrial applications. Eddy will easily cope with most sizes of domestic property and is already in very successful use in small industrial applications which are more arduous than anything likely to be encountered in the domestic situation. We believe that Eddy is the most powerful electronic descaler available for domestic use.

Will I notice an immediate difference after I fit Eddy?
After a few weeks, newly formed scale deposits are soft and powdery and can be cleaned off easily from taps and sinks. Your hot water system may need turning down to a lower temperature setting, saving you money. Kettles start to show a marked reduction in scaling and any scale remaining should become soft and easily rinsed away. Shower heads remain free running and people report that they use less soap, detergents and shampoos. Not only that, but Eddy gets to work on existing old scale and over time should literally clean up your water system and restore its efficiency. Some of our customers have also reported a major improvement in skin problems such as eczema (please see testimonials).

How much does Eddy cost to run?
Eddy draws very little power. At current standard electricity prices, Eddy will cost approximately 10 cents per week to run.

Does Eddy work on copper, lead, plastic or iron pipes?
Eddy can be installed on a copper, plastic, or iron pipe, but we do not recommend installation on pipes made from lead, as descaling a lead pipe may re-expose your water to direct contact with lead. Without descaling, the coating of limescale inside your lead pipes may offer some protection against the detrimental effects of lead on your health. Unlike many manufacturers, we therefore feel unable to recommend installation on lead piping. There is often a pipe of different material (copper or plastic) further "downstream" of where the lead main enters the house so a suitable installation point can usually be found.

What sizes of pipe does Eddy fit?
The US model of Eddy comes with coil cables adequate for fitting on pipes from approximately 3/4 inch diameter up to 1 inch diameter. On a 3/4 inch diameter pipe, each coil is wound with around 40 turns onto the pipe. With larger pipes, less turns are wound (approximately 30 turns onto a 1 inch pipe), but there is no reduction of the magnetic field. Any magnetic field strength lost through fewer turns is made up again by the larger cross sectional area of the coil on the larger pipe. For pipes with a diamter of 1.5 inches or more please see the extra-length coil cable set in our web store ($15).

My incoming water line splits in two after entering the house?
No problem. We designed Eddy with two coils for two reasons. Firstly, because winding two coils around your incoming cold water line increases the time for which the magnetic field is applied to your water, increasing the efficiency of the treatment. Secondly, in situations where the the pipe splits immediately in two after entering the house you can simply wind one Eddy coil on one of the pipes after the split, and the other coil on the other branch.

Does Eddy offer protection to my heating system or water heater?
There are many different types of boiler, furnace and water heating systems commonly installed in the US home. Pumped water heating systems are heated indirectly using a closed circuit of water which is filled and then sealed between boiler/furnace service intervals. Eddy treats the incoming water main and so cannot offer protection of this secondary heating circuit or the boiler heat exchanger in this type of system. You should consult your heating system engineer for advice on additives that may help protect against system damage in hard water areas. Eddy may offer some additional protection to your water heater, primarily any parts that come into direct contact with the incoming fresh water supply, such as inside hot water storage vessels or the heat exchanger in some types of tankless water heaters. The amount of additional protection given is dependent on the exact hardness in your area and also the chemical composition of the naturally dissolved solids in your water supply. Also the operating temperature that the heater is adjusted to work at. In the majority of cases Eddy can be highly effective in helping to reduce scale build up in your hot water heating system.

For how long does the Eddy water treatment remain effective?
Depending on the degree of your water hardness, we would normally expect water treated by Eddy to retain its beneficial properties for up to 72 hours after treatment. This is more than adequate in a house with normal water consumption to ensure that any water in the main cold water storage tank and also the hot water tank is fully replenished before the benefits of treatment wear off. In houses with very low water consumption you may wish to consider fitting an additional Eddy unit to the "exit" pipe from the main water storage tank, though we always recommend trying one unit on the incoming main first as this usually proves more than adequate. In houses where there are no storage tanks, Eddy is at its most effective, as water is used very soon after treatment at the incoming main.

Will Eddy remove scale already present in my water system?
We cannot guarantee that Eddy will remove all of your existing limescale deposits, but Eddy does change the crystal formation of limescale in the water and in time it should slowly dissolve existing deposits. How effective this feature will be depends on many factors, such as the exact hardness of your water, chemical composition and flow rate (flushing action) in your system. In the majority of cases deposits should be slowly eroded after fitting Eddy.

Will Eddy help with skin problems?
We did not specifically design Eddy to help with skin problems, though we have had customers report an improvement in skin conditions after fitting Eddy. Please see our testimonials section for reports from customers.

I've heard that separate "plug-top" power supplies are unreliable?
Some manufacturers claim that "plug-top" power supplies as used with Eddy are unreliable. Our power supplies are manufactured by one of the world's largest power supply manufacturers, who are registered with BS-EN-ISO 9001:2008 standards (the highest standard). They have been specially chosen (like all of the components in Eddy) for supreme reliability which has been well proven during the time that we have used them. The unit is also very small and light - barely larger than a standard power plug.

How long is the cable from power plug to Eddy unit?
The cable from the plug-top power unit to the main Eddy unit measures approximately 6ft. We can supply extension cables if you need to mount the Eddy unit further than 6ft from your available power outlet (see online store).

How much space do I need? How big is Eddy?
The dimensions of the main unit are (w x h x d):
6.75inches x 3.5inches x 1.5inches

Does it matter which way the water flows through the coils?
It does not matter in which direction the water flows, or whether the water flows through the red coil before the yellow coil or vice versa. All that matters is that all of the water that you wish to treat flows through at least one coil or the other or preferably both. For this reason we recommend fitting on the incoming cold water main to the property.

Do units sold for overseas have the correct voltage and style of power plug?
All Eddys are sold with a special power supply that adjusts automatically to the mains voltage in your country. Units sold for the USA have a USA style plug. If you have other requirements, please let us know which power plug style you would like us to supply when you order (USA, Euro or UK).

Is Eddy tested to comply with necessary compliance standards?
Eddy is tested to comply with all necessary FCC standards for sale in the USA.
(Certificates available for inspection).

In what languages is the instruction booklet available?
The instruction manual supplied with Eddy is currently printed in the English language only. We hope to supply a multi language version in the near future.

How long is the parts and labor guarantee?
Eddy comes with a LIFETIME repair or replace guarantee in the event of electrical failure. Should the unit suffer electrical or mechanical malfunction at any time during the ownership of the original purchaser, and be returned to us together with proof of purchase, it will be repaired, or replaced with a unit of identical or updated specification. All components in Eddy are "double rated" to ensure a low failure rate and a very long service life. We are proud to report that very few units are returned because of component failure.

. . . . so what have I got to lose? Absolutely nothing! In the unlikely event that you are unhappy with the performance of Eddy in any way, we offer a no quibble full refund of your purchase cost at any time up to 12 months after your purchase. Order Eddy today and start enjoying the huge benefits of limescale free water in a chemical free, environmentally friendly way.
