When you upgrade from an old gas or electric unit to a quality energy efficient hot water system, it’s common to cut hot water energy use by 50–75%, which adds up to serious annual hot water energy savings for Waterways homeowners.
Most homes in 3195 are separate houses or townhouses, with a good share of three and four bedroom properties, so hot water demand is steady – especially for families with teenagers using long showers. A modern solar hot water heating system or the best heat pump hot water system for your needs can cover the bulk of that demand while keeping running costs low. Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water are all popular options locally, offering efficient choices across heat pump hot water, solar hot water and electric hot water system upgrades.
Typical annual bill savings in Waterways can look like this:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$600 per year • Old electric to modern electric hot water system with solar PV: $200–$500 per year
These ranges will depend on your usage, tariff and how your hot water installation is set up, but they give a realistic idea of what’s possible.
Efficient hot water is already taking off in Waterways. There have been around 940 efficient hot water installations recorded in the 3195 postcode, covering both heat pump hot water installation and solar hot water installation jobs. Install numbers really ramped up from the mid‑2000s, peaking around 2009 with 100 installs in a single year, and there’s been a steady stream of new systems every year since. This shows how more locals are interested in electrification, lower running costs and the most efficient hot water system they can afford.
When you compare heat pump vs solar hot water, the right choice for your home often comes down to roof space, budget, and whether you already have solar panels. A heat pump hot water installation can suit shaded roofs and townhouses, while a roof‑mounted solar hot water system or split solar hot water tank replacement can be ideal for sunny, unshaded homes. Either way, pairing an efficient hot water system with solar PV is one of the easiest ways to cut bills and emissions.
Hot Water Rebates, Tariffs & Savings
Across VIC, there’s growing interest in replacing old gas or electric hot water with efficient options like heat pumps, modern electric hot water system units and solar hot water in Waterways. For many households, the hot water system price or cost is the main hurdle, but current incentives help a lot. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water and heat pump systems, effectively acting as an upfront discount. On top of that, Victorian programmes can offer a heat pump hot water rebate or solar hot water rebate, and in some cases an electric hot water system rebate when switching from gas.
Together, these incentives can reduce the heat pump hot water price or cost or the solar hot water price or cost by a substantial percentage, often bringing premium systems like Sanden heat pump or quality Rheem solar hot water into reach. Many Waterways households see payback periods fall to just a few years, especially when they use timers or solar‑diversion to run their electric hot water installation or heat pump during solar hours. With the right tariff, solar hot water vs electric hot water and electric hot water vs gas hot water comparisons usually come out strongly in favour of efficient, all‑electric options.
If your current unit is older, noisy, or struggling to keep up, it’s a good time to check whether your Waterways home is ready for a hot water upgrade.
