An easy way to determine what types of water heaters can be installed in a particular situation is to use the step-by-step guide available on the Energy Division’s website at www.dtei.sa.gov.au/energy/waterheaters/. See the Information for Plumbers section. This guide is also available at www.piasa.com.au
The water flow rate Standard requires each shower outlet supplied by a new or replacement water heater to have a flow rate of 9 litres per minute or less. This can be achieved by having a gravity fed hot water system, or by installing a shower head or flow rate restrictor with a 3 star water efficiency rating.
Plumbers licensed to install water heaters are required to comply with these water heater and flow-rate standards. Plumbers who become aware of installations that do not comply with these or other requirements should report the noncompliance to SA Water’s Senior Compliance Officer, phone 8463 6096. Reports can be made confidentially.
Illegally installed systems are not only a hazard, but installers who cut corners may be robbing business from plumbers who are doing the right thing.
Plumbers requiring further information can contact the Energy Division’s plumbers information line: 1300 883 019. This information line has been extended up to 19 September 2008..
