Hot water systems in Frankston
Across Frankston, more households are switching from old gas and electric units to modern, energy efficient hot water systems. With power prices rising and many locals paying around $1,845 a month on the mortgage, getting your hot water bills under control simply makes sense. In a suburb with more than 22,000 dwellings and an average household size of 2.4 people, hot water is a big chunk of everyday energy use.
Frankston’s coastal climate is ideal for an efficient hot water upgrade. The local solar exposure at Carrum Downs averages about 15.1 MJ/m² a day – roughly 4.2 kWh/m² – which is strong enough to support both a solar hot water system and a high performance heat pump hot water system. That means better performance from your hot water installation, whether you are looking at a solar hot water heating system on the roof or a compact heat pump on the side of the house. For many families and downsizers here, upgrading from an older gas or resistive electric hot water system can deliver substantial annual hot water energy savings without sacrificing comfort.
In Frankston 3199, most homes are separate houses or townhouses, with more than 17,000 stand‑alone houses and nearly 3,900 townhouses, so there is usually good space for a solar hot water installation or heat pump hot water installation. Many properties already have rooftop solar, so pairing panels with an electric hot water system or a Sanden heat pump or Rheem heat pump hot water unit is a smart way to soak up excess solar and create the most efficient hot water system for your situation. Brands like Rheem solar hot water, Rinnai solar hot water and Chromagen solar hot water are common choices locally, and are often shortlisted when people search for the best hot water system Australia wide.
When you look at heat pump vs solar hot water, both can dramatically cut running costs compared to gas or an older electric unit. A modern electric hot water installation, managed with timers and solar diversion, can also be an energy efficient hot water system, especially in an all‑electric home.
Typical annual bill savings in Frankston can look like:
• Old electric to heat pump hot water system: save about $400–$800 per year. • Gas to heat pump hot water: save around $300–$600 per year. • Gas to solar hot water system: save roughly $250–$550 per year. • Old electric to modern electric hot water system with solar: save about $300–$700 per year.
Since 2002, there have been 741 efficient hot water systems installed in Frankston, combining solar hot water and heat pump units. Installations surged between 2008 and 2011, with around 90–95 systems a year at the peak, and there has been a steady stream of upgrades again from 2018 through to 2024. This reflects a growing interest in electrification, lower running costs and moving away from gas hot water towards options like heat pump hot water, solar hot water vs electric hot water, and even electric hot water system rebate supported upgrades.
Hot Water Rebates, Tariffs & Savings
For hot water VIC households, rebates are a big part of the story. In Frankston, many owners are replacing old gas or electric units with a heat pump hot water system, a more efficient electric hot water system or a solar hot water heating system to cut bills and emissions. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, and Victoria offers additional heat pump hot water rebate options and solar hot water rebate support under state programs. These can reduce the heat pump hot water price or cost, or the solar hot water price or cost, by a substantial percentage, bringing premium products like Sanden heat pumps or Rheem solar hot water within reach.
For some Frankston homes, the effective hot water system price or cost after incentives is hundreds or even over a thousand dollars lower. Combine that with yearly bill savings of several hundred dollars and the payback period can shrink to just a few years, especially if you are using timers or solar diversion. There are also electric hot water system rebate options that can help when shifting from gas, making solar hot water vs electric hot water and electric hot water vs gas hot water well worth comparing. Add in options like solar hot water tank replacement, hot water repair, solar hot water repair and ongoing hot water maintenance, and it becomes easier to keep your hot water VIC system running efficiently for the long term.
