Eddy Limescale Removal System

The most recent reviews for this product are shown below, please use this link to add a review of our Eddy Limescale Removal System,

5/5 Early days to give a full thumbs up (the instructions say it can take some months to see full results) but there seems to be less limescale. The area that i live in has very hard water - the kettle seems cleaner and areas around taps - let's wait another couple of months before unfurling the flags! —Peter Warner

Frequently Asked Questions

If you have any questions about this product, please let us know and we'll do our best to answer.

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!

Where do I fit Eddy?

Eddy is usually fitted to your mains cold water supply pipe (also known as the rising main) at the point where it enters your house. 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 rising main, Eddy should be fitted at the earliest accessible point in the system.

Can I fit Eddy myself?

Anyone should be able to 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 Eddy was designed it was 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. Eddy is one of the most powerful electronic descalers 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 customers have also reported a major improvement in skin problems such as eczema.

How much does Eddy cost to run?

Eddy draws very little mains electricity. At current standard electricity prices, Eddy will cost approximately 10p per week to run at most.

Does Eddy work on copper, lead, plastic or iron pipes?

Eddy can be installed on a copper, plastic, or iron pipe, but it is not recommended to install it 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. It is therefore not recommended install Eddy 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.

My incoming water main splits in two after entering the house?

No problem! Eddy has been designed with two coils for two reasons. Firstly, because winding two coils around your incoming water main 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 main 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. Problem solved!

Does Eddy help reduce maintenance of combi-boilers?

There are many happy customers using Eddy with all types of boiler and other types of water heating system. Combi-boilers are particularly prone to build-up of limescale deposits because of their design. They can then need increased maintenance. There are many customers who report much reduced maintenance requirements after fitting Eddy.

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 loft storage tank and hot water cylinders is fully replenished before the benefits of treatment wear off. In houses with very low water consumption you may wish to consider fitting the Eddy unit to the "exit" pipe from the main water storage tank, though bear in mind that this may mean that not all areas of the house may be treated, i.e. those areas that take a feed of water directly from the water main (often the kitchen).

Will Eddy help with skin problems?

Eddy was not specifically designed to help with skin problems, though there have been customers who report an improvement in skin conditions after fitting Eddy.

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. Eddy's power supplies are manufactured by one of the world's largest power supply manufacturers, "Sun Power" who are certified to BS-EN-ISO 9001:2000 standards (the highest standard). They have been specially chosen (like all of the components in Eddy) for supreme reliability. In the time Sun Power units have been used there has not had one single power supply failure - a testament to their superb reliablity. The unit is also very small and light - barely larger than a standard British mains plug.

How long is the cable from mains plug to Eddy unit?

The cable from the plug-top power unit to the main Eddy unit measures 1.7 metres.

How much space do I need? How big is Eddy?

The dimensions of the main unit are (w x h x d): 17cm x 9cm x 3.5cm ( 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 it is recommended fitting on the incoming cold water main to the property.

Do units sold for overseas have the correct power supply and mains 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. Units sold for other non-UK countries have a standard European style plug. If you have other requirements, please let us know which mains plug style you would like us to supply when you order (UK, USA or Euro).

In what languages is the instruction booklet available?

The instruction manual supplied with Eddy is currently printed in the English language only. The Eddy unit itself is tested to all required CE and FCC standards for worldwide sale.

Is the 12 month money back guarantee really "no quibble"?

The 12 month money back satisfaction guarantee is completely "no quibble". If you are unhappy with the performance of you Eddy unit for any reason whatsoever within 12 months of purchase, simply return the unit for a full refund of your purchase cost.  Don't forget to retain proof of purchase. As a matter of principle any returned unit will be tested and you will be informed of any fault condition so that you can request a replacement unit. Eddy is sold for DIY installation so costs incurred from the use of professional tradesman for fitting Eddy will not be reimbursed . A negligible number of returned units are received and the vast majority of customers are highly satisfied with the performance of Eddy which either meets or far exceeds their expectations.

How long is the parts and labour guarantee?

Eddy now 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 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. Very few units are returned because of component failure.
