Across the 5016 postcode there have already been 152 efficient hot water installations, combining both heat pump and solar hot water installation jobs. Install numbers built steadily through the 2000s, peaking around 2003–2010, and there has been renewed interest again since 2015 as energy prices climbed and electrification gathered pace. Each new heat pump hot water installation or solar hot water system reflects a local household choosing lower running costs, fewer emissions and a quieter, safer alternative to gas.
For a typical Largs Bay home, hot water can be one of the biggest single energy users, so the savings from an upgrade are substantial. Swapping an old electric hot water system for a quality heat pump hot water system – such as a Sanden heat pump, Rheem heat pump hot water unit or similar – can trim usage by up to two‑thirds. A well‑designed solar hot water system, whether it is a rheem solar hot water, rinnai solar hot water or chromagen solar hot water setup, can cover most of your hot water needs from the sun, with an electric booster for cloudy days.
Here is a guide to realistic annual bill savings for Largs Bay households, depending on your starting point and tariffs:
• Old electric to heat pump: save around $350–$700 per year. • Gas to heat pump: save roughly $250–$500 per year. • Gas to solar hot water: save about $200–$450 per year. • Old electric to modern electric with solar: save around $200–$400 per year.
Actual hot water system price or cost will vary with brand, size and installation complexity, but these savings show why many locals now compare heat pump vs solar hot water rather than sticking with gas. When you factor in a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate where eligible, the effective heat pump hot water price or cost and solar hot water price or cost can drop significantly. Federal Small‑scale Technology Certificates (STCs) reduce upfront cost for approved solar hot water systems and heat pumps, and South Australian programmes can offer additional hot water rebate SA style incentives for efficient upgrades. Combined, these can slice a substantial percentage off the invoice and shorten the payback period to just a few years, especially if you run your system on daytime solar or use timers and smart controls.
For many households in Largs Bay, the choice comes down to solar hot water vs electric hot water, or electric hot water vs gas hot water. A modern, energy efficient hot water system powered by your solar PV or an ultra‑efficient heat pump is usually the most efficient hot water system option overall, helping you future‑proof your all‑electric home and reduce exposure to gas price rises. If you already have an older solar hot water tank, a solar hot water tank replacement and solar hot water repair can bring it back to peak performance, while those on ageing gas units might be better off with a full hot water installation of one of the best heat pump hot water system options on the Australian market.
