Hot water systems in Heathwood
Across Heathwood and the wider 3134 area, more households are swapping old gas and electric units for an energy efficient hot water system that actually keeps bills under control. With an average household size of around 2.6 people and more than 12,700 dwellings, hot water demand adds up fast – especially for busy families and downsizers alike. Rising energy prices mean upgrading your hot water system is one of the simplest ways to lock in long‑term savings.
Heathwood’s climate is well suited to efficient hot water. The local Bayswater weather station records mean daily solar exposure of about 14.6 MJ/m², or roughly 4 kWh/m² per day across the year. That level of sunlight supports strong performance from both a solar hot water system and a modern heat pump hot water system, particularly when paired with rooftop solar. For many homes owned outright or with a mortgage – over 8,900 in the postcode – shifting from older gas or resistive electric hot water to a modern heat pump or solar hot water heating system can deliver impressive annual hot water energy savings.
In Heathwood, three‑ and four‑bedroom separate houses make up the bulk of homes, so a typical family hot water installation might be a 250–315L heat pump hot water system or a roof‑mounted solar hot water installation with a 300L tank. Many homes already have solar PV, so an electric hot water system with a smart timer can soak up daytime excess, while others are moving straight to all‑electric with a Sanden heat pump or Rheem heat pump hot water unit. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices for a solar hot water heating system, while premium Japanese units such as a Sanden heat pump are popular with households chasing the most efficient hot water system on the market.
Typical annual bill savings in Heathwood look like this:
• Old electric to heat pump hot water system: save around $350–$700 per year. • Gas to heat pump hot water: save about $250–$600 per year. • Gas to solar hot water system: save roughly $200–$550 per year. • Old electric to modern electric hot water system run on solar: save about $250–$500 per year.
Over time, these savings help offset the hot water system price / cost, especially when you factor in rebates and lower maintenance. For many households, a quality heat pump hot water system is now considered among the best hot water system Australia options, with the best heat pump hot water system often beating both gas and standard electric on running costs.
Recent years have seen steady growth in efficient hot water across Heathwood. There have already been 584 efficient hot water installations (heat pump and solar) recorded in the postcode. Installations jumped sharply around 2008–2011, with peak years like 2009 seeing 60 systems installed, then continued at a solid pace through the 2010s and into the 2020s. Even in 2024 and 2025, dozens more systems have gone in. This trend shows growing local interest in electrification, lower running costs and getting off ageing gas hot water in favour of an energy efficient hot water system.
Hot Water Rebates, Tariffs & Savings
For hot water VIC households, rebates are a big part of the equation. Federal Small‑scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost or heat pump hot water price / cost, and Victorian schemes can add a heat pump hot water rebate or solar hot water rebate on top. There may also be an electric hot water system rebate when replacing old, inefficient units. Together, these hot water rebate VIC incentives can cut the effective system cost by a substantial percentage, often shaving years off the payback period. Combine a heat pump vs solar hot water choice with rooftop solar, smart tariffs and timers, and many Heathwood homes are saving hundreds of dollars a year while enjoying reliable hot water VIC wide.
If your current unit is nearing the end of its life, needs frequent hot water repair, or you are facing a solar hot water tank replacement, it is a good time to compare heat pump vs solar hot water and even solar hot water vs electric hot water. For some homes, a modern electric hot water installation powered by solar makes sense; for others, a dedicated heat pump hot water installation or solar hot water repair and upgrade is the smarter move. Either way, electric hot water vs gas hot water is tilting strongly towards efficient electric in Heathwood.
