Product Features

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.

View Sizing Table

Water-King Sentry

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.

Water-King WK-SE

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

Water-King WK2

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.

Water-King WK3

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.

Water-King WK4

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.

Water-King WK5

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.

Suggested Specification & Technical Advice

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.
