What to know about hot water install in Adelaide
New hot water installations in SA must include a compliant tempering valve (max 50°C at the bathroom outlet) under AS 3498 and the Plumbing Code of Australia. Every network plumber includes the tempering valve in the quote. If you see a quote without one, ask for a revised line item.
Heat pump and solar installs trigger federal STC rebates plus SA-specific incentives under the Energy Productivity scheme. The plumber handles the paperwork; you should get the post-rebate price in writing before you commit. A heat pump quoted at $5,500 pre-rebate is often $3,700 to $4,500 out of pocket after rebates.
Gas hot water work in SA requires the plumber to also hold a Gas Fitter registration. Every gas appliance install must come with a Certificate of Compliance issued through the Office of the Technical Regulator. Network plumbers always issue the certificate - never accept a gas install without one.
