Instant hot water at 99.7% energy efficiency
The Billi Kwikwash I Series incorporates unique heating technology that directly heats the water without using a conventional resistance element, called Optimised Direct Energy Transfer. The unit will use no power at all unless the tap is being used. When the water flows, the system determines the exact amount of energy needed to heat the water to the required temperature reducing scale and increasing efficiency.
Using life-cycle analysis, the heating technology, installed in medium density apartments, is up to 3.1 times more energy efficient than gas and up to 1.6 times compared with solar-boosted gas!
No TMV requirement
As the KwikWash I Series unit has an incorporated temperature monitor, it is able to provide water within +/-1.5C, eliminating the need for a TMV reducing upfront installation and ongoing maintenance costs. This is unique in the instant water heating market. The Billi Kwikwash has been tested to and is compliant with NSW Health requirements.
Typically hot water units are rated to different inlet water temperatures which means you are required to choose the correct system. The Billi Kwikwash I Series has a single model which delivers the accurate temperature water no matter what the inlet temperature.
Note; not suitable for SA and WA due to water quality and conductivity requirements. New model to follow.
The Billi KwikWash incorporates an inbuilt safety sensor which prevents the temperature exceeding 43.5°C eliminating the risk of scalding.

Every Billi KwikWash I Series is manufactured under an ISO9001 certified quality control system. The Billi KwikWash has been tested and complies with all required standards: Tested to AS/NZS 3498 and AS/NZS 4020. C-Tick approved; Watermark License Number 22136; AS/NZS 3500 In accordance with AS/NZS 3500 Section 1.9, the Kwikwash does not require the installation of tempering valves or thermostatic mixing valves, tested and certifies as meeting the requirements of NSW Health*; AS/NZS 60335.2.35 and IEC 60335.2.35 for electrical safety; IP rating is IP44
*Certificate available on request
Yes. The technology used in KwikWash I Series is new. It is this revolutionary new technology that delivers these additional features and benefits:
The unit draws just the required amount of power, just when it is needed. It may draw up to 40Amps, but it only uses energy while the tap is in use.
The unit will stop and restart. Every time the unit restarts it needs to be run for about 1min before it will start to heat again.
The unit will stop working and the LED on the front will go RED. This may happen intermittently in areas where the water supply agency blends water from different sources.
