Hot water systems in Queensferry
Across Queensferry and the 3984 postcode, more homeowners are rethinking their old gas and electric hot water system and moving to smarter, energy efficient options. With an average household size of around 2.3 people and more than 2,900 dwellings, many locals are families and downsizers looking to cut bills without sacrificing comfort. Median household incomes sit in a sensible middle range, so every dollar saved on running costs matters.
Queensferry’s coastal climate is well suited to an efficient hot water upgrade. Nearby Corinella records mean daily solar exposure of about 15.1 MJ/m², which is roughly 4.2 kWh/m² per day over the year. That steady sunlight helps both a solar hot water system and a modern heat pump hot water system perform well, especially when paired with rooftop solar. For many homes, shifting from older gas or resistive electric units to an energy efficient hot water system can deliver substantial annual hot water energy savings, freeing up money for other household costs.
In this part of Victoria, most homes are separate houses, with a good mix of three and four bedroom properties, so hot water demand is steady year‑round. Many households already have solar PV, making the choice between heat pump vs solar hot water a practical conversation rather than a theoretical one. Brands like Rheem heat pump hot water units and Sanden heat pump systems are popular for all‑electric homes, while Rheem solar hot water and Rinnai solar hot water are common choices for those wanting a full solar hot water heating system with roof collectors and a solar hot water tank replacement when the old cylinder finally gives up.
Typical annual bill savings in Queensferry look like this:
• Upgrading an old electric hot water system to a heat pump hot water system: around $400–$800 per year • Switching gas hot water to a heat pump: around $300–$600 per year • Switching gas to a solar hot water system: around $250–$550 per year • Replacing an old electric unit with a modern electric hot water system and using rooftop solar: around $200–$500 per year
Over time, these savings can offset the hot water system price / cost, especially once rebates are applied. Many locals ask about the best hot water system Australia has to offer for their situation. For some, the best heat pump hot water system is a premium Sanden heat pump or high‑efficiency Rheem heat pump hot water unit. Others prefer a robust solar hot water installation using Rheem solar hot water, Rinnai solar hot water or Chromagen solar hot water components. Where a simple replacement makes more sense, a quality electric hot water installation can still be an energy efficient hot water system when paired with solar PV and smart timers.
Recent installs in Queensferry and the wider 3984 area show how quickly things are changing. There have been around 800 efficient hot water systems installed here, combining heat pump hot water installation and solar hot water installation jobs. From just a handful of systems in the early 2000s, installations jumped sharply from 2016 onwards, peaking in 2022 with 125 new systems before remaining strong through 2023 and 2024. This steady growth reflects rising interest in electrification, lower running costs and moving away from gas hot water.
Hot Water Rebates, Tariffs & Savings
Across Victoria, and specifically for hot water VIC upgrades in Queensferry, there is strong interest in replacing ageing gas or electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water heating system. Australian Government Small‑scale Technology Certificates (STCs) can reduce the upfront solar hot water price / cost or heat pump hot water price / cost, while state programs often add a heat pump hot water rebate or solar hot water rebate on top. There are also schemes that can provide an electric hot water system rebate when you move to more efficient technology.
For many Queensferry households, these hot water rebate VIC incentives can cut the effective system cost by a substantial percentage, turning a multi‑year payback into just a few years, especially when combined with rooftop solar and off‑peak or flexible tariffs. Typical savings from an efficient hot water upgrade can easily reach hundreds of dollars a year, particularly when you use timers or solar diversion to ensure your hot water installation runs mainly on cheap or self‑generated power. When you compare solar hot water vs electric hot water or electric hot water vs gas hot water on total running costs, efficient electric and solar options usually come out ahead as the most efficient hot water system over the long term.
If your system is leaking, running out of hot water, or simply getting old, it is a good time to check whether your Queensferry home is ready for a hot water upgrade.
