Water-King offers specifiers and installers an easy to install, maintenance free, non-chemical alternative to traditional hard water treatments. For sizing and location guidance, please read the information below or call our technical helpline on 01608 811707
Lifescience Products Ltd are experts in physical water conditioning with a reputation built over more than twenty years of providing the best technical advice and hard water treatment solutions to consulting engineers, installers and plumbing merchants.
We have been at the vanguard of alternative water treatment technologies with much of our research now accepted as industry standard.
In general we recommend installing Water-King as close as possible to where water is being heated and scale is most likely to form. This ensures that continuous treatment is delivered to the area where it’s needed most. In practice this normally means installing a Water-King on the cold water supply within the same plant room as the water heater.
Where point-of-use electric water heaters are installed and hot water demand is sporadic, such as in an office, it’s best to fit a dedicated unit to each water heater or cluster of heaters.
The signal generated by Water-King is continuously transmitted through the water, both upstream (back signal) and downstream, irrespective of flow. This means that appliances upstream of the unit can also be treated, although the signal won’t work as effectively through pumps and storage cisterns. Water-King units should be fitted after pumps and tanks to ensure signal transmission to downstream services.
When installed tactically in this way Water-King will deliver continuous treatment to downstream services, ensuring all of the water is treated all of the time. This is unlike alternative technologies that only treat water as it passes through the device, relying on a temporary signal memory to treat downstream services.
Cold water storage tanks can cause discontinuity in the signal transmission resulting in decay of the clustering effect generated by Water-King. This problem is overcome by installing Water-King on the outlet pipes and utilising a ‘back signal’ to treat the stored water.
Pumps cause a significant reduction in the effectiveness of Water-King so, in general, wherever there is a pump there should be a Water-King installed downstream.
In practice Booster Pumps will often be located immediately downstream of a cold water storage tank. Installing a Water-King after both will ensure continuous signal transmission to the downstream services.
We recommend that Hot Water Secondary Return pipework be treated with a Water-King installed between the circulation pump and the water heaters or buffer vessel.
For Re-Circulating Systems where water is constantly circulated, such as swimming pools, the Water-King should be fitted downstream of the pump, as close as possible to where the heating process is occurring.
For Irrigation Systems install a Water-King after the pump. On high pressure master lines we recommend installing a Sentry unit to each line.
Where a pump is installed on the cold water inlet side of a Heat Exchanger, such as on a plate frame heat exchanger or Modular Tank Heater like the Andrews MAXXflo, it is more effective to treat the hot outlet side. The signal from Water-King will travel in both directions, treating both the heat exchanger upstream and buffer vessels downstream.
Much of the scale formed in these fittings is precipitated from cold water. Even when a conventional softener is installed to treat only the hot water services it is common to find scale forming in mixing valves, shower heads and taps. Fitting a Water-King on the cold water services will reduce this scaling.
Each Water-King aerial requires up to 6cm of straight pipe. Pairs can be fitted either side of bends on vertical or horizontal pipes. No plumbing is required nor is there a need for a bypass. Insulation can be fitted over aerials after installation.
Units should be located within one metre of a power supply and 45cm of the pipe.
Having decided where to locate Water-King select an appropriately sized unit according to the pipe diameter.
If water is being heated then select the larger size according to the maximum output rating based on the type of water heater installed (this varies according to whether they are gas fired, oil fired or electrically heated).
Running costs of all Water-King units is less than £15.00 per annum. The design life is in excess of 25 years with no servicing or maintenance requirements and a 5 year manufacturer’s warranty. There is also a 100-day money back guarantee, extendable by negotiation.
Every Water-King unit comes pre-fitted with a “guard chip” which monitors the performance of the main program and resets the system automatically if it detects any variation or system failure. There is no need for manual resetting after a power outage.
Our entry level unit designed with the needs of housing associations, landlords and build to rent developers in mind. It is suitable for pipe sizes up to 28mm, easy to install, tamper resistant and automatically resets so requires no monitoring. It is also fully waterproof so can be used in damp and hostile environments, including catering applications and external irrigation systems. It is ideally suited to protecting individual appliances and heaters.
Designed for treatment of high output electric water heaters or hot water cylinders with multiple immersion elements. It should be selected for individual heaters or clusters of heaters where heat output is up to 12kW
Larger and more powerful than the Sentry. It has two pairs of aerials which can be used to reinforce the signal to a single pipe (up to 42mm) or be split between two smaller pipes. This arrangement ideally suits the designs of many heat exchangers.
A powerful unit designed for most commercial applications. It is frequently specified to treat mains cold water supplies to direct fired water heaters and paired with a Sentry on the secondary return. The WK3 and all larger units feature an LCD display and benefit from an output for building management systems (BMS) to detect power failure.
Designed to treat larger commercial applications, with pipe sizes up to 108mm. It is frequently used in high rise office and residential developments, student accommodation blocks and hotels where it can provide continuous treatment to downstream services irrespective of flow.
The largest standard Water-King. It has six aerial outputs arranged as three pairs and is designed to be used in the same applications as the WK4 but where the pipe size is up to 159mm. Larger units are available upon request.
For consulting engineers looking to specify Water-King for their projects we recommend inclusion of the following text:
"One or more Water-King electronic water conditioner shall be fitted to the cold mains supply and HWSR in accordance with the manufacturer’s recommendations.
The unit shall have one or more pairs of open-ended aerials wrapped around the pipework generating a series of square waves of random length and occurrence between 1kHz and 10kHz. The peak to peak output voltage will be in excess of 80 volts.
Units should be proven by independently laboratory tests to partially soften hot water and performance tested using the IGC-335 protocol. "
Where technical advice is required, please contact our helpline. We’re experienced at advising consultants and contractors on the most effective way of treating hard water using water conditioning technologies. We are also able to provide CIBSE and CIPHE accredited training seminars for those looking for a more detailed understanding of the technology.
