Shifting from old gas or resistive electric hot water to a heat pump hot water system, solar hot water heating system or efficient electric hot water system is a logical next step if you are already thinking about electrification or solar. Families and downsizers alike are looking for the most efficient hot water system they can reasonably afford, because hot water can be one of the biggest single energy users in the home. In a postcode with a median household income around $1,389 a week and plenty of separate houses, the annual hot water energy savings from upgrading can make a real difference to cash flow over time.
Across 3741 there are 2–3 bedroom homes, chalets and apartments, so hot water demand varies, but the pattern is similar: long winters, heavy hot water use, and a strong incentive to lower running costs. Local installations often feature brands like Rheem heat pump hot water, Sanden heat pump units for very high efficiency, and Rheem solar hot water or Rinnai solar hot water for properties with good roof space. For many, a quality heat pump hot water installation is now seen as the best heat pump hot water system choice for cold climates like Hotham Heights, while others prefer a robust solar hot water installation with an electric booster.
When you look at heat pump vs solar hot water, both can deliver big savings compared with gas or an older electric hot water system, especially when you factor in a solar hot water rebate or heat pump hot water rebate. Typical average annual bill savings in a Hotham Heights-style climate might look like:
• 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–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year
These ranges depend on tariffs, household size and how you use hot water, but they give a feel for what is possible. Upfront hot water system price / cost, heat pump hot water price / cost and solar hot water price / cost will vary by brand and size, and there are options from mid-range to premium. Systems from Solahart, Thermann and others sit alongside Rheem solar hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water in the local market, so it is worth getting tailored advice on the best hot water system Australia can offer for your specific property.

Install numbers ramped up sharply around 2009, with 59 systems that year, and have continued at a steady pace since, with additional installs each year right through to 2024. This trend shows growing interest in hot water VIC upgrades that reduce reliance on gas, lower running costs and support all-electric homes that pair well with solar PV.
Hot Water Rebates, Tariffs & Savings
All of this interest in hot water VIC upgrades is being helped along by generous incentives. For Hotham Heights homeowners, Australian Government Small-scale Technology Certificates (STCs) reduce the effective solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, the Victorian hot water rebate VIC programs can offer further discounts on an approved heat pump hot water system or solar hot water system, and in some cases on an efficient electric hot water system rebate as part of a broader energy upgrade. Together, these hot water rebate VIC schemes can cut the upfront hot water system price / cost by a substantial percentage, often bringing payback periods down to just a few years. When you add rooftop solar, timers or solar-diversion controls so your electric hot water installation or solar hot water tank replacement runs mainly on sunshine, the savings can jump again, often worth hundreds of dollars per year off bills.
For many properties, the choice comes down to solar hot water vs electric hot water or electric hot water vs gas hot water. A well-designed energy efficient hot water system, whether it is a rheem solar hot water setup, a sanden heat pump, rheem heat pump hot water or another best heat pump hot water system option, will usually beat older gas on both emissions and long-term cost. And if you ever need hot water repair or solar hot water repair, local specialists can assess whether it is better to fix the old unit or move to a modern replacement.
