Hot water systems in Kearns
Across Kearns, more households are switching to energy efficient hot water systems to keep bills down and future proof their homes. With most of the 3,500-plus dwellings being separate houses and an average household size of three people, hot water demand is solid, especially for busy families on median mortgages of around $1,950 a month. Upgrading from an older gas or electric hot water system to a modern heat pump hot water system, solar hot water system or efficient electric hot water system is a logical way to trim running costs without sacrificing comfort.
Kearns enjoys strong sunshine, with nearby Varroville recording an average annual solar exposure of about 16.2 MJ/m² per day – roughly 4.5 kWh/m²/day. That level of sun makes a solar hot water heating system or heat pump hot water system a smart match for local roofs, particularly where homes already have solar power. For many owners, hot water energy use is one of the biggest chunks of the power bill, so choosing the most efficient hot water system can deliver meaningful savings year after year.
In 2558, the typical three to four bedroom family home uses plenty of hot water for showers, washing and cleaning. That is where efficient hot water system price and performance really matter. Brands like Rheem and Rinnai are common choices for solar hot water installation and electric hot water installation, while premium options such as Sanden heat pump units are popular with homeowners chasing the best heat pump hot water system on the market. For solar hot water, systems like Chromagen solar hot water and Rheem solar hot water are often paired with rooftop PV to maximise daytime self consumption.
When you compare heat pump vs solar hot water, the right answer in Kearns usually comes down to roof space, budget and when your household uses hot water. A heat pump hot water installation can work well even on shaded roofs, while a solar hot water installation shines on north facing roofs with clear sun. Either way, both options are generally more efficient than a standard electric hot water system, and far cheaper to run than older gas units. Even a modern electric hot water installation, when timed to run on solar, can be a very energy efficient hot water system.
To give you a feel for the numbers, here are typical annual bill savings for Kearns homes (actual results depend on usage, tariffs and system size):
• Old electric to quality heat pump hot water system: $400–$800 per year. • Gas storage to heat pump hot water: $300–$600 per year. • Gas storage to solar hot water system: $250–$550 per year. • Old electric to modern electric hot water with solar: $200–$500 per year.
Over the years, Kearns has seen 176 efficient hot water installations, combining heat pump and solar hot water systems. Installations peaked around 2009 and 2010, with 49 and 29 systems installed respectively, and there has been a steady trickle of upgrades since, including new systems in 2023 and 2024. This pattern shows a long running local interest in electrification, lower running costs and moving away from gas hot water where possible.
Hot Water Rebates, Tariffs & Savings
For Kearns households, hot water nsw incentives are making it easier to replace old gas or electric units with efficient options. The Australian Government’s Small scale Technology Certificates (STCs) reduce the upfront hot water system price for eligible solar hot water and heat pump systems, effectively cutting the heat pump hot water price or solar hot water price by a substantial percentage at install time. On top of that, state based schemes can offer a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate for approved upgrades, especially when replacing gas. These hot water rebate nsw programs can shorten payback periods to just a few years, particularly if you also have rooftop solar and use timers or solar diversion to heat water when the sun is shining.
Whether you are weighing up solar hot water vs electric hot water, electric hot water vs gas hot water, or planning a solar hot water tank replacement with brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump or Chromagen solar hot water, it pays to get local advice.
