With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.
With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Comet and the 4702 area, 2,215 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.
With Comet's climate delivering an average of 5.7 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot Water Demographics - Comet
Based on the Australian Bureau of Statistics 2021 Census (ABS), Comet has around 11,695 private dwellings, home to approximately 25,902 people. With an average household size of 2.7 people, and around 50 litres of hot water used per person each day in Australia, Comet households use approximately 135 litres of hot water daily, equating to a massive 1.6 million litres of hot water used across the suburb every single day.
Other census insights reinforce Comet's suitability for energy-saving improvements like energy-efficient or solar-powered hot water. The Comet community is home to 2,326 couple families with children and 751 one-parent families, meaning a large proportion of households face substantial hot water demand. With 3,462 homes owned with a mortgage and 3,316 owned outright, many residents also have the homeownership and growing equity that make switching to efficient hot water systems a practical way to lower expenses.
Comet is converting hot water demand to efficient systems faster than many peers, with 18.9% of dwellings already upgraded.
Hot water systems in Comet
Across Comet and the wider 4702 area, more households are switching from old gas and tired electric units to modern, energy efficient hot water systems. With an average household size of around 2.7 people and thousands of separate houses across the postcode, reliable hot water is non‑negotiable – but so is keeping power bills under control. Many families are juggling mortgages of about $1,560 a month and median household incomes near $1,649 a week, so upgrading to a more efficient hot water system is a logical way to bank long‑term savings.
Comet is blessed with serious sunshine. The local weather station records mean daily solar exposure of about 20.6 MJ/m², which is roughly 5.7 kWh/m² per day – ideal conditions for a solar hot water system or a high‑efficiency heat pump hot water system. That strong solar resource helps a solar hot water heating system deliver most of your hot water for free, and it also boosts the performance of heat pump hot water, especially when paired with rooftop solar. For many homes, hot water can be one of the biggest energy users, so shifting to an energy efficient hot water system can deliver meaningful annual hot water energy savings.
In the 4702 postcode, most dwellings are three‑ and four‑bedroom homes, so hot water demand from showers, washing and dishwashers quickly adds up. That is why more locals are comparing heat pump vs solar hot water and even looking at modern electric hot water system options that work with solar. Brands like Rheem heat pump hot water, Sanden heat pump units and Rinnai solar hot water systems are increasingly common, alongside trusted names such as Rheem solar hot water and Chromagen solar hot water for roof‑mounted and split systems.
Typical bill savings for Comet homes upgrading their hot water installation look like this:
• Old electric to heat pump hot water installation: save roughly $350–$700 per year. • Gas to heat pump hot water system: save around $250–$600 per year. • Gas to solar hot water installation: save about $300–$650 per year. • Old electric to modern electric hot water installation with solar: save roughly $250–$500 per year.
So far, around 2,215 efficient hot water systems have been installed in the 4702 area, covering both heat pump and solar hot water installation projects. Install numbers climbed strongly from the mid‑2000s, peaking between 2007 and 2011 when over 200 systems a year went in, and they have remained steady since, with ongoing installations from 2020 through to 2025. This steady trend shows growing local interest in electrification, moving away from gas hot water, and cutting running costs with the most efficient hot water system a home can reasonably fit and afford.
Hot Water Rebates, Tariffs & Savings
For Comet homeowners, there is strong interest in replacing old gas or electric hot water with efficient options such as a heat pump hot water system, a solar hot water system or a modern electric hot water system that can run on rooftop solar. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively lowering the upfront hot water system price by hundreds of dollars at the point of sale. On top of that, Queensland programmes can offer a heat pump hot water rebate or solar hot water rebate from time to time, and an electric hot water system rebate may also be available for certain efficient models.
When you combine a hot water rebate QLD options with solar feed‑in tariffs and smarter controls, payback periods can shorten dramatically. Many Comet households see total heat pump hot water price and solar hot water price paybacks drop to just a few years, especially when using timers or solar‑diversion so the system heats mainly during sunny hours. That can mean hundreds of dollars a year off bills and a much lower lifetime hot water system cost compared with sticking with basic electric hot water vs gas hot water tariffs.
If you are wondering about the best hot water system Australia can offer for your Comet home, it often comes down to your roof space, budget and whether you already have solar. A well‑sized Sanden heat pump or similar best heat pump hot water system can be ideal for all‑electric homes, while a quality Rinnai solar hot water or Rheem solar hot water setup can be a great fit if you have good north‑facing roof space. For older properties, solar hot water tank replacement or solar hot water repair may be all that is needed to restore performance, while others might be better off with a completely new hot water installation.
If your current unit is ageing, noisy or your bills keep creeping up, now is a smart time to look at hot water QLD options and compare solar hot water vs electric hot water and heat pump choices. Talk with experienced local hot water repair and installation specialists who understand Comet’s climate, tariffs and housing.
