Savings with sonic

With the ever increasing cost of energy it is essential to have a really efficient plumbing system.

When hard water becomes limescale it forms a thick layer of chalk on the heat exchangers in your water heating system which effectively acts as a thermal insulator. This STOPS the heat generator from heating efficiently so requiring more and more energy to heat the same amount of water. This is a complete waste of energy which increases your energy costs.

In addition the problems caused by hard water such as dry skin and eczema, poor use of soap and detergents are all too apparent. The old salt system of water softeners (ion exchange) is cumbersome and expensive and requires costly plumbing along with a need for a dedicated pipe for a supply of untreated cold water to your drinking tap.

(which you will almost certainly use to fill your kettle, thus retaining the limescale problem in all boiled water!) It is not advisable to drink water treated by a salt water softener as it is bad for you plus the fact that it is not at all palatable!

Modern electronic water softener units such as Elemental’s Sonic range require no chemicals or maintenance and can be fitted without plumbing and is an easy DIY installation for most people. The units deliver softer water as well as removing and preventing limescale at a fraction of the cost of the older style salt water softener systems which many people now regard as obsolete.

With water treated by the Elemental Sonic water softener unit you have drinking water all round your property and available from every tap. As Calcium is good for you and helps developing children’s bones and teeth this is an additional bonus

Choosing & Installing your Sonic unit

In order to choose the most appropriate Sonic unit you need firstly to consider your type of plumbing system. Is your plumbing UNVENTED with no water tank in the loft as in the first diagram below or is it VENTED as in the second diagram with a water tank in the loft. When you have decided you will then need to go to our Easy Selection Chart below to choose the unit/units you require

Unvented Plumbing Systems

(i.e. with Combination boiler or unvented Pressurised system such as Megaflow and no loft tank)

Where? It really doesn’t matter where you install your Sonic unit as long as it’s on the COLD mains pipe. This is because Sonic puts a ‘current’ in the water like a beam of light, which travels up-stream and down-stream to the remotest parts of the cold plumbing system. It is NOTHING to do with the direction of the water flow!. Also it doesn’t matter whether the Sonic unit is lying on its side or upside down. A lot of people now use two-sided Velcro to attach the Sonic unit to a wall, as they really don’t weigh very much (under 200gms). Don’t worry about what the pipe is made of. Sonic works very well on all pipes including plastic, galvanised and copper.

If your boiler is some distance from where your water enters the property you should fit a second Sonic unit on the cold pipe into the boiler. If you have a larger property with say 5+ bedrooms you will need an WS2 on the cold pipe and you may also consider a dedicated WS1 on the cold feed to the boiler if the house has several bathrooms.


(i.e. with Combination boiler or unvented Pressurised system such as Megaflow and no loft tank)

Sonic units will only treat the water if there is no break in it. With a tank in the loft, the water fills up the tank through a ball valve so there is a break in the current. The water in the tank becomes untreated.

You will either need to install 2 x WS1s, one on your cold mains and one on the cold down service or if your cold mains pipe to the tank in the loft and the cold down service to your hot water cylinder run parallel together in your airing cupboard as they often do, you can fit an WS2 as in the diagram below. One aerial is wrapped around the cold mains and the other is wrapped around the cold down service. Don’t forget that the WS2 has 4 times the output of the WS1.

You may also find power in the airing cupboard too either as a fused spur or a plug. Have a look in your airing cupboard and if you have a 3-pin plug then installation of the WS2 is very easy. If not then you will need to ask an electrician or a plumber capable of electrical installation who holds a Part P certification.

You will also find a smaller tank in the loft, which is the top-up tank for the central heating. The water in the central heating system is sealed and already treated with a chemical to stop scaling so needs no further treatment. If you have a larger property with say 5+ bedrooms then you should install a WS2 on the cold mains and an WS1 on the cold down service to your hot water cylinder.

The WS3 Solo (the only one in the world) is equivalent in output to a WS1 but requires no mains supply as it runs on batteries.

Larger properties with 10+ bedrooms will require an WS5 on the mains inlet and an WS2 on the cold down service. If you have a secondary return pipe to the boiler then another WS2 should be fitted to this.
