Maximum pipe diameter 67 mm
Direct Fired Water Heaters – We recommend maximum heat rating for different sized units and this also varies
according to whether they are gas fired, oil fired or heated electrically.
Direct fired gas / oil 350 kW
Electrical boiler 50 kW
Flow Rate – Flow rate is immaterial as far as Water-King is concerned. The greater the flow, the more effective
the units tend to be.

All Water-King units work on all pipe materials (with the exception of lead). Pipework lagging can also be re-attached, once Water-King aerials have been installed. Water-King will also deliver continuous treatment both upstream and downstream irrespective of flow or usage, providing units are correctly located after pump-sets and storage tanks, unlike other technologies that rely on a temporary memory effect

Self-Diagnostic “Guard Chip” – Every computer system is prone to malfunction, especially if there is a sudden
variation in the power supply, which can jam the program. Most systems have to reset by manual re-booting.
Water-King units overcome this problem by an additional “Guard Chip” program, which monitors the performance of the main program and resets the system automatically if it detects a variation or system failure.

There is no need for manual resetting after power outage.
Maintenance – Once installed, the WK3 requires no maintenance.

Lifecycle costs – Running costs are less than £15.00 per annum. The design life is 25 years with a 5-year manufacturers
